An Introduction To The Monika System
Purpose Of The System A Monika system provides centralised monitoring and management of one or more temperature controlled environments. Most commonly these environments include refrigerators, freezers, cold rooms, servery counters, dishwashers, display cases and other cold or hot storage units. Wherever temperature-critical items such as food, pharmaceuticals, chemicals and organic materials are held, Monika has an application. In the areas of food service, food retailing or food processing, use of a Monika system can ensure simple, trouble free compliance with food hygiene regulations. The availability of logged data will enable the demonstration of due diligence should the need arise. How The System Works The Monika system consists of a central console linked to ‘slave’ units in the cabinets or rooms to be monitored. The slaves process information from probes and other input channels, and transmit it back to the console. The Monika slaves communicate with the Monika central console via “RF” (Radio Frequency) transmission. Each slave unit is wired either to a transformer outputting 12V or to a 12V supply from the electrical supply of the storage units to be monitored by the system. Usually it is mounted within the control enclosure. Probes are screwed into the slave units, and mounted at strategic monitoring points within the cabinet or cold room. The probes monitor the temperature or other required data for transmission by the slave to the central console. Each slave can support two probes and two status monitors. A number of different types of probes are available. They include product simulation packs for monitoring food temperatures, air/fluid probes for monitoring air and liquid temperatures; door-open limit switches for monitoring whether doors are open or closed; and others. The slave also incorporates additional status monitor input channels to sense whether specific circuits are switched on or off. In a refrigeration system it would be normal to monitor whether the refrigeration plant is running or idle, and whether the unit is in defrost or not. On other types of unit it is possible to monitor whether the unit is being used or not. Monitoring Functions The Monika console is continuously monitoring all units on the network with pre-determined maximum and minimum temperature ranges established for each cabinet. As soon as temperatures move outside these ranges the potential for an alarm condition arises. Time delays can be specified to allow for temporary temperature deviations. Once the time delay is exceeded, the alarm will register. Similar procedures apply to door open and other monitoring options.

System Requirements Chef’s / Catering Manager’s Office(s):
• Network Master Unit (NMU) requires a dedicated single socket mains supply (13A/230V) at its proposed location. (and may also require a LAN socket point)
• Docking Cradle and (Optional auto dialler) each require a dedicated power supply (13A/230V) adjacent to the NMU.
• Pentium Class PC running Windows 2000, XP or Vista with Internet Explorer 6 or later, two spare Comms Ports (RS232 or USB) and a CD ROM drive. LAN connection maybe required.
• A dedicated BMS normally open/closed connection terminated at the NMU location. (Optional)
• Dedicated dial in/dial out telephone extension sockets are required for auto-dialler (Optional)
Networking of monitored units:
• A fused spur (13A/230V) is required for each slave Repeater necessary to ensure complete network continuity.
Process Locations (Goods in, Production, Serving): A wall mounted Hand Reader docking cradle will require a dedicated power supply (13A/230V) at a suitable point in each specified process location and may also require a LAN socket point.

Overview of installation process
Equipment
The following equipment should be carried at all times when visiting a Pathfinder RF site.
• Laptop running AVR Studio, Tibbo DS Manager and Telegesis Terminal
• Telegesis Co-ordinator module (USB or CF)
• STK500 and PSU and/or AVR ISP MK11 – for programming and debugging
• USB Serial adapter for above (if required)
• Gateway debug lead (for old style Gateway)
• Wi-Spy Spectrum analyser (if required)
• Crossed network patch lead for Tibbo diagnostics
Planning the Installation It is recommended that the network is established and configured during the hardware installation phase. This minimises the amount of configuration work and reduces potential diagnostic work later on. However it is accepted that this is not always possible and the network may need to be configured after the hardware has been installed. The key to a trouble-free installation is working methodically and completing the Site Installation Schedule as work progresses. This will ensure that you have all the information available for configuring Monika PC later on, without having to reopen control panels to check ID’s and or probe allocations. It is recommended that you first identify all the areas to be monitored and the central monitoring point where the NMU and PC will be located. On LAN based sites each remote area should be considered as a self-contained network with the LAN converter as the central data collection point. TIP: Contact the site’s IT department when you first arrive on site so they can arrange for suitable access to the PC for the software installation.

Interfacing the Monika NMU to BMS
The Monika NMU (Part 2001) is equipped with a volt-free alarm contact to allow
connection to other alarm systems. The contact will change state if an
unacknowledged high temperature or communication alarm persists for more than a
given period, or if the power to the NMU is lost. Custom alarm strategies can be set
up so that BMS alarms are only active between specific periods for specific cabinets.
When connected, the alarm contact will only provide an indication that an alarm
exists, it will not provide a temperature signal; the user will have to view the alarm in
Monika PC in order to establish the specific alarm.
The alarm contact socket is a 6-pin DIN socket situated on the base of the NMU on
the right hand side with the connection details given below:

Pathfinder RF Slave Selection Chart: General rule of thumb:
Use Single Probe Slave if only 1 temperature probe is required AND no monitoring of Compressor/Defrost/Door Open etc is required AND the unit is never switched off.
Use Multifunction Slave if 2 temperature probes are required OR monitoring of the Compressor/Defrost/Door Open etc is required OR the unit will be switched off when not in use.
Use High-Performance Slave if a Multifunction Slave is required but the Slave Unit itself will be installed inside a metal box thus degrading RF performance (such as inside a Dishwasher Unit).

Monika Food Simulation Pack Installation Guide Warning; before carrying out any installation work, ensure that the equipment being worked on is totally isolated from the mains supply.
1. Determine the location of the Simulation Pack within the cabinet, ensuring that;
• It is not in direct airflow.
• It is not liable to damage from the door opening and closing.
• Does not impede placement of internal racking.
• There is sufficient room to access the fixing screws from below.
2. Mount the Simulation Pack backing plate in the chosen location using fixings appropriate for the type of surface.
3. Route the probe cable between the Monika Slave and the probe location. Select the most appropriate cable entry and knock out the blanking plug. Ensure that the cable is:
• Securely fixed.
• Will not impede normal use of the cabinet.
4. Connect the probe cable to the terminal strip in the backing plate.
TE-D2098-E Page 24 of 115
Mount the Simulation Pack to its backing plates as follows: Snap out the cable exit as required. This is only necessary when using the side or bottom cable entries.
5. Connect the loom to the male connector above the terminal strip.
TE-D2098-E Page 25 of 115
6. Mount the body to the backing plate. Insert the upper of the cavity in the body first.
7. Secure with 2 off M3x6 CSK screws into the holes on the lower surface of the body.
TE-D2098-E Page 26 of 115
Monika Air / Fluid Probe Installation Guide The Air and/or Fluid Probe can be used in conjunction with the food simulation pack or independently according to the users requirements. An A/B or C/D probe gives a temperature of the current air, fluid or other medium in contact with the stainless steel tip, inside which, is a potted thermistor bead. These two types of probe are used in conjunction with the 3 Pathfinder RF slave unit types allowing temperature ranges to be monitored to a high degree of accuracy for slave/probe combinations and temperature ranges.
Installation
Warning; Before carrying out any installation work, ensure that the equipment being worked on is totally isolated from the mains supply.
This is the standard probe for use at refrigeration and incubation temperatures below
60C. Installation of an A/B probe depends on its designated purpose. In most applications the probe is used to indicate whether the refrigeration process is functioning correctly within the unit or not. In cold room environments the probe should be located in the air on position centrally behind the evaporation unit. This allows the user to monitor the temperature of air flow in to the evaporation unit before being cooled in order to alert of any general air temperature problems due to door left open or refrigeration problems etc. In a smaller enclosed refrigerated unit the probe should be located in the air off position. The smaller area means that the difference in temperatures between air off and air on to the evaporator is reduced and therefore refrigeration problems or unit operation problems will show themselves accordingly.
• The Air Probe should be located and secured approximately 25mm to 50mm away from the evaporation coil (adjacent to the manufacturers probe where possible) in both air on and air off applications.
• Ensure that the stainless steel tip is not in contact with any surface especially the evaporator coil and fins and that air is flowing freely around it.
• If an Air Probe has been specified for a still air unit such as fish fridges, displays or milk packs it is essential that the probe is located at a point that will monitor refrigerated air.

Fluid Probe Position Installation Of Type Fluid C/D Probe
The type C/D probe is used to monitor temperatures above 60C. It is essential that
the probe has heat resistant cable and seals up to the maximum temperatures it will
see. A C/D probe is used mainly to monitor hot units such as dishwashers, bain
maries and heated storage units. The optimum position in this type of unit is alongside
the existing manufacturers control thermostat probe e.g. within a dishwashers wash or
rinse tanks or the food storage area of hot units and bain maries.
Dishwashers Purpose Of Monitoring A dishwasher has several critical temperature control points in order to provide an effective and clean wash cycle. These points are easily identifiable and temperatures must be taken regularly to ensure that the units operation is providing a thorough and hygienic cleansing of pots and crockery. Probe Positions
• The points that should be monitored are wash and rinse tank temperatures.
• It is not always possible to place the C/D monitoring probe directly into the tank or into the gland containing the units own thermostatic control probe.
• Where this is not possible the probe must be attached with direct contact to the outside of the appropriate tank.
• The other option is to attach the probe with direct contact to the appropriate tanks water feed pipe to the operational area of the dishwasher. If this option is chosen, the water must be heated prior to entering the pipe. The Monika probe may require calibration against the actual tank water temperature to confirm correct readings.
TE-D2098-E Page 29 of 115
Out of Use Monitor Note; This connection can only be made where a slave’s power supply remains live whilst the unit it is monitoring is switched off.
• Where required, connect the orange wire from the Monika slave unit to the load side of the monitored units on/off switch. This will give a supply status indication to the Monika slave. In the case of a dishwasher this can be found on the switched side of the power supply contactor.
• Ensure that this is on the same supply phase as the supply to the slave unit.
TE-D2098-E Page 30 of 115
Coldroom Probe Position Warning; Some circuits within coldroom control panels, usually lighting, will remain LIVE when main isolator is in the OFF position.
• Ideally the slave unit should be located within the cold room control panel or in a separate enclosure box adjacent to it.
• Power for the slave unit should where possible be taken from the coldroom control circuit which will normally be fed from a low current supply. Do not take the supply directly from the main isolator.
• The defrost connection point should be determined by first locating the defrost contactor control feed and working back to a convenient terminal (usually found on the defrost time clock). Note that some units may be using NEUTRAL switching.
• The white ‘compressor monitor’ should be connected such that it monitors control-thermostat activity as distinct from compressor activity. Depending on the type of control system compressor activity is not always an indication of cooling activity.
• Cold room installations will usually involve longer and more complex cable routing which will require the use of suitable conduit or trunking. It is sometimes possible to use spare capacity within existing cable containment but care must be taken to ensure that the integrity of the existing installation is maintained.
• Holes will normally need to be drilled through the insulated walls and ceilings of the room to allow probe cables to be installed. Before drilling such holes always establish exactly where the hole will exit and that there is no risk of damaging any fixtures (e.g.; cable runs on other side).
• When drilling or fixing in a food storage area always ensure that there is no danger of contamination of the products contained within.

General A/B & C/D Probe Installation Procedures
Warning; Before carrying out any installation work, ensure that the equipment being worked on is totally isolated from the mains supply.
• Once the probe location is confirmed the tip should be secured with a cable gland if conduited or cable tie where appropriate.
• It is essential that any fixings and cable will withstand the units maximum and minimum temperatures.
• The probe cable must be run back to the relevant slave as neatly as possible so as not to compromise the units functions. Ensure that the probe position and subsequent cable route do not affect the removal and refitting of any of the units shelving.
• This can be carried out by various methods according to the environment to be monitored e.g. PVC conduit in cold rooms or cable ties in smaller units running alongside existing pipe work or cabling where possible.
• When fitting the probe and cable it is essential that there are no refrigeration pipes or other obstacles that can be damaged in the area. This applies especially to still air units using an A/B probe such as fish fridges, display cabinets, chest and ice cream freezers.
• Care should also be taken to ensure the cable cannot be damaged whilst in situ, for example by door movements, fan blades or defrost heaters.
Any holes drilled for cable access must be grommeted, cable gland or silicone sealed to protect the cable and create an air/fluid seal. The probe is mounted to the cabinet wall using the four 4mm mounting holes provided in the back plate. Suitable fastners include pop rivets or stainless steel self-taping screws. The probe should be mounted within the food compartment of the unit being monitored. It should be out of the direct air flow from the evaporator fans but not in a ‘dead air’ spot. Particular attention should be given to minimising the affects of warm air entering the cabinet near the door and the heating effect from any internal lighting.

Installation Procedure for New Sites
This procedure is for sites where no equipment has previously been installed. If you are installing additional equipment or attending a site that is part complete you should refer to the section on Network Configuration after Installation. In all cases the installation should be broken up into areas. 1. Set up the laptop in a convenient location where it will be in RF range
of the Gateway and slaves being installed. Plug in the USB or CF card Co-ordinator module in the laptop and start the Telegesis Terminal application. Select the appropriate COM port that your Co-ordinator module is using (you may have to check in the Windows Device Manager to determine this) and connect to the coordinator by clicking the ‘Connect’ button. When you have successfully connected the terminal window will become active. Verify that you have communication with the Co-ordinator by clicking the ‘Reset’ button. You should see the AT&Z command appear in the terminal window and the ‘OK’ response. This command will restore the factory defaults and ensure that the new network is established on a channel available to factory default devices.
TE-D2098-E Page 33 of 115
TE-D2098-E Page 34 of 115
2. Establish a PAN with the ‘Establish PAN’ button. The Coordinator will
scan the available channels and establish a new PAN on the best available channel. The Coordinator will also join this PAN after a few seconds. Make a note of the PAN on the Site Installation Schedule for future reference.
3. If possible you should now install the NMU and Gateway, or LAN Converter if you are starting in one of the remote areas. This is because these units are the ‘SINK’ for their respective areas; the node that all the monitoring units send their data to. Refer to the hardware installation section for details. If this is not possible then start installing the first slave.
TIP: If you are working in a operational kitchen, plan your work around the busy areas e.g. avoid working in the main cooking area during meal service times, or in the office when the Chef is ordering or planning his menus.
After installing the Gateway or first slave and powering it up check the laptop to verify that the new unit has joined the PAN. This can take a minute or so and is usually evident by a NEWNODE:<SLAVE ADDRESS> string in the terminal window. However, this is not always the case so you should periodically scan the PAN for new nodes using the ‘Scan PAN’
TE-D2098-E Page 35 of 115
button. Any new nodes (slaves, Repeaters, Gateway etc) will be displayed in the device window.
Once the new unit has joined the PAN you need to ‘lock’ it on to that PAN by programming its PAN ID register. This is done using the ‘Set PAN ID’ button. After pressing the button you will need to select the unit from the Device List and enter the four digit PAN ID (you should have made a note of this on the (installation Schedule).
4. Continue to install the rest of the slaves and networking equipment using the above method. It is not recommended but circumstances may dictate that you have to install several pieces of equipment before you can configure them on the laptop. This is not a problem but you have to be careful to ensue you configure each unit later and don’t miss any.
TE-D2098-E Page 36 of 115
Configuring a Network After the Installation This procedure should be used when configuring a site that has hardware installed, but not configured.
1. Reset the Coordinator module using the RESET button. This will restore the factory defaults and ensure that the new network is established on a channel available to factory default devices.
2. Use the SCAN FOR PANS button to search for any PANs that may
have already been established. This is likely if slaves and repeaters have been fitted and powered up on a previous visit. If any PANs exist they will be displayed in the terminal window:
Make a note of any PANs found for future reference.
TE-D2098-E Page 37 of 115
TE-D2098-E Page 38 of 115
3. If no PANs are discovered then you will need to establish a new PAN with the ESTABLISH PAN button. The Coordinator will scan the available channels and establish a new PAN on the best available channel. The Coordinator will also join this PAN after a few seconds. You should now find that slaves and repeaters will start to join this PAN. This is indicated by ‘NEWNODE’ strings appearing in the terminal window. It may take several minutes for all the units to join and it is possible to miss the NEWNODE string for some units, so it is best to periodically press the ‘SCAN PAN’ button to search for any units that have joined. Following a scan any units that have joined the PAN will be displayed in the right-hand terminal window.
4. After several scans you should find all the slaves, repeaters and other
nodes on the network.
5. Refer to any documentation you have to determine the addresses and locations.

Monika PC Software Installation
Product Description Monika PC™ is a fully integrated Temperature Management and Reporting System. Key Features The system comes in four integrated modules. Modules can be added together as the size of your business increases:
1. Wireless Hand Probing, combining the RFID Hand Reader and Probe to create a cordless logging thermometer.
2. Food Simulation logging, where temperature histories are collected
from storage locations with the same wireless hand reader. 3. Networked monitoring, where temperatures are monitored centrally
from storage locations on a continuous basis. At the heart of our system is the Network Master Unit, which is the conduit to the PC. Data is stored on this unit, which continues to function during PC downtime. When the PC connection is restored, the computer is updated automatically with missing data. The master unit is networked to Food Simulation Probes mounted in fridges and freezers, away from the direct airflow. These probes contain a food stimulant, and move in temperature in line with the actual food products stored. There is also an optional RFID Hand Reader. When used in conjunction with special RFID insertion probes, this acts a cable-free logging thermometer. It can also be used to collect data from Stand-alone Food Simulation Loggers, which may be used in fridges etc., which are impractical to network due to cost or location. Basing the new Monika™ probe on RFID makes it battery free. The temperature data is transferred to the hand reader over a wireless RFID link. The probe itself uses a tiny digital temperature chip mounted in the point of the spike, replacing the thermister or thermocouple and related electronics used in conventional probes. These technologies make the probe simple, accurate, reliable and low cost. Tags within the probes also enable them to be programmed for sampling specific products at specific locations. This information is collected when the temperature is taken, ensuring that the temperature is correctly linked to product and point of production. The result is a ‘cordless logging traceability thermometer’.

TE-D2098-E Page 55 of 115
Before Upgrading Monika PC
Identifying the COM Ports used by Monika PC The first step before upgrading your Monika PC Software is to identify which COM Ports Monika PC uses to connect to the Network Master Unit and Hand Reader Docking Cradle. To identify the COM Ports used by Monika PC you must log into Monika PC with a username that has full “Manager” privileges. Once logged onto Monika PC, click on the “Setup” menu item on the tool-bar: Now click on “Operational Configuration” to open the configuration dialog: Now click on the “Connections” tab: Listed here at the top of the dialog is the COM Ports currently used by Monika PC. The first COM Port listed is used to connect Monika PC to the Network Master Unit (NMU) and the second COM Port listed is used to connect Monika PC to the Hand Reader Docking Cradle. Please take a note of both of these for selection later after the software has been upgraded. You can now close the “Operational Configuration” dialog. Identifying the location of the Monika PC “Data” folder The Monika PC “Data” folder holds all the settings for Monika PC plus all the recorded readings downloaded to Monika PC. The “Data” folder can be in a number of locations depending on the existing Monika PC Software version and the choice of location made when installing the existing software e.g. the “Data” folder may be installed onto a “Network” drive on a Server for backup purposes. Firstly identify the existing Monika PC Software version. To do this click on “Help” on the tool-bar and select “About”. This will display a dialog detailing the software version and current licensing: The version number is written at the top of the dialog: If your current version is 1.3.X.X or less the “Data” folder will either be on a “Network” drive or located at: C:\ Program Files \ Monika \ Monika PC \ Data
TE-D2098-E Page 56 of 115
If your Monika PC version is greater than 1.3.X.X then the “Data” folder is again either on a “Network” drive or located at: C:\ Documents and Settings \ All Users \ Application Data \ Monika \ Data The “Application Data” folder in “All Users” is usually a “hidden” folder so if you cannot see the folder when you have opened “All Users” then click on “Tools” on the menu-bar and select “Folder Options”: Click on the “View” tab and in the “Advanced Settings” window at the bottom of the dialog, under the “Hidden Files and Folders” section, click on the radio button beside “Show hidden files and folders” and then click on “OK” to close the “Folder Options” dialog. You should now be able to see the “Application Data” folder and within this folder you should find the “Monika “ folder. Please make of note of the location of the Monika PC “Data” folder so during the installation of the upgraded version you can select the same location. Download Hand Readers before upgrading Monika PC Before continuing with upgrading Monika PC you should dock all your Hand Readers and download all readings to prevent any possible synchronisation issues. Shut down Monika PC before continuing with the new installation.

Trouble-shooting the Pathfinder RF Network
There are some odd things that can happen if a Pathfinder RF system has been left without configuring it at the time of installation e.g. it is possible for two PANs to be created with the same ID if they are in isolated parts of the kitchen. In nearly all cases it is possible to rectify the situation with the following procedure. To simplify the procedure it is assumed that you are familiar with the Telegesis Terminal software and conversant with Pathfinder RF terminology. If not then please refer to the relevant section of this manual.
1. The factory defaults on all Pathfinder RF equipment have S0 (S Register 0), the channel mask, set to FFF0 (hex). This masks channels 11,12, 13 and 14. If the existing PAN on site has been established on one of these channels then the new slaves will not be able to join it. Check the sites PAN ID to establish if this is the case. e.g. 12,3432 indicates a PAN on channel 12 with ID 3432.
The table below details how the channel mask is set (channels in RED are not useable by units with factory default register setting)
Hex F F F 0
Binary 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0
Channel 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11
2. Before starting the procedure it is advisable to have a full list of all the
Pathfinder RF units on the network; this information should be available on the original Installation Schedule. This will help ensure that you do not end up with any ‘orphaned’ nodes on the network.
3. Join the current PAN and make a note of its channel and ID. Clear the Device window and perform a scan to pick up all the slave, repeaters and other nodes on the PAN. Refer to the list of nodes (see above) and check that they are all visible.
4. Reset the channel mask of the visible nodes by performing an ATSALL00=FFF0 command.
5. Now determine a new PAN ID to use for the new network, this can be any 4 digit hex number as long as it is not the same as any other PANs on site. Make a note of the new ID for future reference. Perform an ATSALL01=<NEW ID> to set the PAN ID of all the visible nodes to the new ID.
6. Disassociate each of the nodes in turn with the DASSR (button reference) command. Always start with the nodes that are furthest away from the Co-ordinator so that you don’t become isolated from the network. Leave the PAN.
7. Now perform an AT&F to reset the Coordinator to the factory defaults, then set the Co-ordinator’s PAN ID to the new one you decided on above by typing ATS01=<NEW ID>
TE-D2098-E Page 66 of 115
8. Establish a new one with AT+EN. The Co-ordinator will establish a new PAN with the new PAN ID and on one of the unmasked channels. Make a note of this new PAN for later reference..
9. The disassociated nodes should now start to join the new PAN. This could take several minutes so periodically press the SCAN button to pick up the new nodes as they join.
10. Once all the nodes have joined you should find that the old PAN ceases to exist, but if another PAN with same ID as the original existed then that will now be visible if you scan for PANs. To do this and be sure of picking up all PANs you will need to set the Co-ordinator to view all channels by removing the channel mask. Do this by sending ATS00=FFFF to the Co-ordinator. Now scan for PAN’s.
11. If no PANs are discovered then move to another area of the kitchen and rescan, in case you were in a location out of RF range.
12. If other PANs are found join the first one and perform a scan. There should be nodes visible otherwise the PAN would not exist. Send the ATSALL00=FFF0 to reset the channel masks on all the nodes on that PAN, then ATSALL01=<NEW ID> to set their PAN IDs to the newly created PAN.
13. Now disassociate each of the nodes in turn. 14. Leave the PAN and then scan for PANs to see which PANs remain.
Continue with steps 11 through 14 until you have removed all the node from all the remaining PANs, until you are left with only new PAN you created.
15. Check all the nodes you find against the Installation Schedule to verify that you have found all nodes that were installed.
16. Join the new PAN, clear the Device List and then scan for nodes. You should find that all the nodes you removed from the other PANs start to join the new one. Periodically perform a scan until you have all the nodes on the PAN.
17. If you are still left with some nodes that have not joined the new PAN then it is best just to replace these units.
If a new ‘factory fresh’ slave (or other Pathfinder RF unit) cannot be found on the PAN after power up:
1. It may have joined another PAN, either a new on or one with the same ID as the one you are scanning.
2. It may not be able to join the PAN if the existing PAN has been established on a channel masked by the S0 register.

Checking Telegesis Modules Registers Are Set Correctly All Monika Slave Units should have these registers set at the factory:
Register Value
0D 003F
0E 003F
26 0028
27 0111
28 0111
To check if these registers are set, send the command for each register:
Command
atsrem0D:<module id>?
atsrem0E:<module id>?
atsrem26:<module id>?
atsrem27:<module id>?
atsrem28:<module id>?
To set these registers on a Slave Unit, send these commands to the unit:
Command Function
atsrem0D:<module id>=003F Sets current value of register 0D to set the I/O direction to be an Input
atsrem0E:<module id>=003F Sets power up value of register 0D to set the I/O direction to be an Input
atsrem26:<module id>=0028 Sets the frequency of sending data to the “SINK” to 10 seconds
atsrem27:<module id>=0111 Sets functionality of register 26
atsrem28:<module id>=0111 Sets power up value of register 27
All Monika Gateways / LAN Converters should have this register set at the factory to make them a “SINK”:
Register Value
06 010C
To set this register, send this command to the module:
Command Function
atsrem06:<module id>=010C:TG-ETRX1 Set remote module to be a “SINK”
Command is case sensitive as the “TG-ETRX1” is a password and needs to be in capitals.
TE-D2098-E Page 68 of 115
All Monika Repeaters do not need to have any registers set as they are just used to connect distant Areas/Slaves etc together. Other Programming Issues
All modules should appear in the Telegesis Terminal as “FFD” (Full Function Device). If this is not the case for a module then send the command: atsrem06:<module id>=000C:TG-ETRX1 You will then have to disassociate the module from the network and allow it to rejoin again, it will then appear as an “FFD” and from there send the other commands required to set the module up to be what you want it to be.

Trouble-shooting an old style Gateway (new Gateway built into the NMU) The old style Gateway is a fairly simple device. Its function is to receive Pathfinder RF data strings on one channel, store any them in memory, and pass this data back to the NMU on another channel when requested. Basic Functionality Test Power up the Gateway and check that the LED gives one brief flash. If this is not the case then switch off immediately and check the power connections. Unplug any ST, LAN or RF cards and try again. If the LED now flashes then there is a problem with one of the cards. If the LED still does not flash then check the power supplies. If the +5 and +15 are not present then check the main fuse on the board.
Symptom Possible Cause
Action
Both +5V and +15V supplies are dead
Fuse blown Check and replace fuse
+5V supply missing
Check regulator is soldered to
board correctly.
+15V supply missing
Check regulator is soldered to
board correctly.

The debug Output The Gateway has a serial output that can be used for diagnostic purposes. You will need an STK500 dev board and comms lead to make the connection to your laptop. Connect to the gateway as shown below. CONNECTION DIAGRAM HERE If switches 7 and or 8 are closed on the Gateway board then various debug data is transmitted on the zigbee port. In this case it is important that the data is not transmitted to the zigbee sink. If switch 7 is closed, all characters received from the NMU are transmitted as two hex characters and a space. In addition, if a poll message is detected (i.e. at the end of a poll message) then a <cr><lf> is also transmitted. If switch 8 is closed the following data is transmitted: s if a setup poll message is received. SAAAAZZZZZZZZ
If a setup message is received. AAAA is the eeprom address (slave ID * 4), and the Z’s are the zigbee ID stored in the eeprom.
p1<sp>AAAASSstp1p2 p2<sp>AAAASSstp1p2
if a valid normal poll message is received. p1 and p2 give the probe number, AAAA is the data table address (slave ID * 4) and the SSstp1p2 are the contents of the data table as described previously.
n is added to the above if the seconds count is 0. m if a normal poll message has an invalid ID or the command byte is not 0. EAAAASSstp1p2
If a zigbee message is received. AAAA is the eeprom address (slave ID * 4), and the SSstp1p2 is the data stored in the data table.

Trouble-shooting a LAN Converter Basic Functionality Test Power up the LAN Converter and check that the LED flashes continuously. If this is not the case then switch off immediately and check the power connections. Unplug any ST, LAN or RF cards and try again. If the LED now flashes then there is a problem with one of the cards. If the LED still does not flash then check the power supplies. If the +5 and +15 are not present then check the main fuse on the board.
Symptom Possible Cause
Action
Both +5V and +15V supplies are dead
Fuse blown Check and replace fuse
+5V supply missing
Check regulator is soldered to board correctly.
+15V supply missing
Check regulator is soldered to board correctly.
Check Tibbo Device is appearing on the LAN Power up and connect LAN Converter to the LAN and then Using DS Manager scan for the device. If the device does not appear on the LAN then return to the LAN Converter and check the LEDs on the Tibbo Device. If the Tibbo is powered up but has no Ethernet Connectivity then the LEDs should show only a “Green” flashing light which indicates it’s waiting for a LAN Connection. Check the network socket it is plug into is working correctly and if so check the patch lead being used or replace it. If the LAN Converter is on the LAN but keeps dropping off the LAN then the problem may lie with the regulator on the board. Check that it is soldered correctly to the board and the heat sink is making good contact with it. If there is not a problem with the LAN Converter but you are still not getting temperatures from the Slave Units in that area then check the RF Module in the unit is set to be a “SINK”. If it was not the “SINK” then the problem may lie with the RF Module “seeing” another “SINK” on the same PAN. Change the PAN ID for that area to be different to all other areas. All LAN Converters should be setup to be on a different PAN to any other on that Site so that “SINK”s do not see each other as there can be only 1 “SINK” per PAN.
TE-D2098-E Page 74 of 115
Trouble-shooting the LAN System
There are essentially three elements to a LAN based system: the NMU/Gateway, LAN converter(s) and the Monika Pathfinder LAN service.
The Monika Pathfinder LAN Service can be debugged via a Telnet session, for convenience there is a shortcut in the Monika Program Files menu. To begin a debug session click the shortcut and the following window will open. In the sample below the NMU/Gateway IP address (Master) is 192.168.1.249, and there is one LAN Converter with address (Slave) 192.168.1.46. The number after the address in both cases just identifies the port being used and is always 1001.
You should see a steady stream of streaming Slave strings. The strings will be in random order but you should see all LAN Converter IP Addresses appearing without any “Could not connect…” messages. If you do see any “Could not connect…” messages then check the LAN Converters are functioning correctly and appear on the LAN via Tibbo’s Device Manager. If you see the message “Could not connect to Master” (the “Master” being the NMU/Gateway) then check the NMU/Gateway is on the LAN. If the Gateway is the older style that is not integrated into the NMU, then use Tibbo’s Device Manager to check the settings on the Gateways Tibbo Device and that it appears on the LAN (see below for settings). If the Gateway is integrated into the NMU then use Telecom Design’s Device Manager to check the settings on the TD-Extract module (see below for settings).

Also change the “Ethernet” type from “Automatic” to “100 baseT”. Please note that the “Serial Baud Rate” does not display when being read back but should be set to 19200 as shown above. Click on the “Send Config” button to set the parameters on the device. The module currently being used is a G3 but this may be replaced a G4 where the Monika LAN Service can run on it without having to install the service on a computer or Server.

Trouble-shooting Slave Units
Checking that the Slaves Sending Data
Sometimes it can be difficult to determine if the slaves on the network are actually sending data back to the Sink. You can verify this by temporarily setting your Co-ordinator as the Sink. First switch off the Gateway or LAN converter for the area you are in. Join the PAN of the network you want to test the slaves on. Then set the Co-ordinator as the SINK by typing ATS06=010C. After 20 seconds or so you should start to see NDATA strings streaming in from the slaves. You can confirm which slaves are sending data from the address after the NDATA characters. After the test perform a factory reset on the Co-ordinator so that it is no longer the SINK.

TE-D2098-E Page 89 of 115
Handreader Charging Problem
Before carrying out any work on a returned Handreader we need to identify where the problem with charging may lie. Firstly place the Handreader in a known working cradle and leave on charge for at least 8 hours or until the display shows the Handreader to be “Full”. Remove the Handreader from the cradle and place against a WIP on “Check Only” and time how long it takes before the Handreader shuts down. A fully charged Handreader should be able to read a WIP for up to 3 hours. If the Handreader manages this without further checks then the problem may lie with the cradles on site that are being used to charge it. If the Handreader does not manage at least 2 hours then follow the actions given below:
Handreader Issue
Modifications Done
Action
Is the Handreader a new model? (Issue 7 on the PCB board)
All modifications are integral to the PCB
Check Contact screws on Handreader as shown below
If contacts are ok or problem persists check / replace battery
Checking The Battery On The Handreader Open the Handreader to check the data written on the battery. If no date appears or is over 1 year old then replace the battery with a new one and write the current date on the battery. Replace the cover on the Handreader (but don’t replace overlays yet) and place on charge for at least 8 hours and perform the “Check Only” test against a WIP again. If the Handreader now passes the test replace overlays and return to site. If Handreader still fails after this then return to Monika for further investigation.
TE-D2098-E Page 90 of 115
Checking The Handreader Charge Contacts
Check that the correct number and type of washers and screws are fitted. There should be a red fibre washer and a stainless steel wave washer installed as shown below.
Check that the contact screws are tightened sufficiently to ensure that the internal thread insert is making good contact with the connection eyelet. Keep tightening progressively until a positive increase in resistance is felt. As a guide this will be around a torque value of 1Nm.
Checking The Docking And Charging Cradle Contacts Ensure that the cradle charging contacts protrude by 4-5mm and that they are free to move, and do not stick in when fully depressed.
TE-D2098-E Page 91 of 115
TE-D2098-E Page 92 of 115
Cradle Charging Problem
Checking The Docking And Charging Cradle Charge Current
1. Connect a 9V DC 500mA supply to the power jack. 2. Check that power LED illuminates. 3. Check the voltage across the charge contacts is steady 9V±2 VDC. 4. Check that the unit is regulating current to 400mA by connecting an
ammeter across the charging contacts.
If the unit fails the above test then open the case and check the soldered connections to the charge contacts and the PCB, as there may be a dry joint or broken connection. Give each wire a gentle tug to make sure it is secure.

Cradle Comms Problem
Checking For “Noisy” Docking Cradle Comms The easiest method to check for a noisy Docking Cradle is to use Monika PC and have a Handreader placed in the cradle. Open the “Show Log Window” from the “Engineers” menu item and open the “Comms” tab. Disconnect from the NMU if connect. Watch the raw Comms for a while, if you do not see any red writing or items reported as “Invalid Char” / “Bad Serial Header” then the cradle is OK and would indicate the cradle was not at fault on site but the Handreader or PC to Docking Cradle lead (but do modify the cradle anyway with the modification shown at the end of this document). If you do see something like the following then follow the modification shown at the end of this document:
TE-D2098-E Page 95 of 115
Other Methods To Determine If Docking Cradle Is “Noisy”:
2023 Docking Cradle (and serial connection on 2021) Set up a HyperTerminal session with the following COM Port settings:
Bits per second 115200 Bits 8 Parity none Stop Bits 1 Flow Control Hardware
With no Handreader in the cradle there should be no characters appearing in the HyperTerminal window. If random characters are appearing then cover the IR window on the cradle in case the random characters are due to ambient IR then they will stop. If the characters continue then the cradle is suspect and should be replaced or modified.
2021 Ethernet Cradle From a DOS prompt Telnet to the cradle’s IP address on port 1001 as shown:
Telnet <IP ADDRESS> 1001 With no Handreader in the cradle there should be no characters appearing in the Telnet window. If random characters are appearing then cover the IR window on the cradle. If the random characters are due to ambient IR then they will stop. If the characters continue then the cradle is suspect and should be replaced or modified.

Pathfinder RF Compatibility Issues
Overview
There are often concerns when operating RF (radio frequency) based products in certain sensitive environments. Generally such concerns relate to the potential for the system to interfere with other electronic equipment, or a more specific concern regarding the affects on existing RF based networks or devices. Monika recognises this and has chosen its RF technology to address, as far as possible, both of these areas of concern. Firstly, the Monika Pathfinder RF system operates within the ubiquitous 2.4 GHz band that is recognised worldwide. This was chosen since the proliferation of wireless networks and communication devices, operating predominantly within this bandwidth, effectively preclude the notion that RF radiation within this part of the electromagnetic spectrum can be avoided. Also Monika’s relative low power and data rate ensures that a Monika system will form a negligible proportion of the background level of RF in this band. Secondly, Monika has chosen to use a ZigBee based technology compliant with the internationally recognised IEEE802.15.4 standard which forms part of the IEEE 802 range of harmonised standards covering, amongst others, wireless networks. This ensures its safe co-existence with other RF technologies within the scope of the standards, most notably 802.11b/g; wireless LAN or ‘WiFi’. As a further safeguard against interoperability issues, Monika configures its systems to operate on specific ZigBee channels that fall outside the range of those used by standard 802.11b/g wireless LAN networks, namely channels 15, 20, 25 and 26, as indicated below.
TE-D2098-E Page 113 of 115
In addition to the above, the RF elements of a Monika system have appropriate approval such that: 1) The device may not cause harmful interference. 2) The device must accept any interference received, including that which may cause undesired operation.
