16. Simultaneous Data over GPRS and SMS
When GPRS data upload is unsuccessful, GSX8 will redial and try to connect to GPRS network for re‐
uploading the data.
During the redial interval or re‐uploading the data via GPRS DATA, any SMS command will be lost and
schedule SMS data upload will also be dismissed.
Therefore, when the GPRS data upload interval is short, it is recommended to select a longer SMS
upload interval and vice versa.
It normally takes about 45~60 seconds to complete an incoming SMS command or outgoing SMS data
upload.

17. Data over Ethernet
17.1) Ethernet Data
Both UDP & TCP protocol are supported in Ethernet Data.
Packet Data format over Ethernet is supported only when GPRS is enabled.
17.2) Data Upload Interval
Upload Interval is the same for both GPRS and Ethernet Data.
17.3) Can the server receiving GPRS data and the server receiving Ethernet data the same computer?
Computer installed with Ultimate Server software will be able to receive data over GPRS
and Ethernet at the same time.

20. How Data Logger response on alarm?
Alarm is triggered when Digital Input state is changed or AD Input reading is higher or lower than user
preset values. User can be alerted via Ethernet, SMS or GPRS when alarm is triggered.
When first level alarm is triggered:
Live Data will be uploaded to Server via GPRS or Ethernet header: STH
Live Data will be sent to Control Centre via SMS header: STH
Alarm Text will be sent to Alarm Phone via SMS header: STA
When second level alarm is triggered:
Live Data will be uploaded to Server via GPRS or Ethernet header: STG
Live Data will be sent to Control Centre via SMS header: STG
Alarm Text will be sent to Alarm Phone via SMS header: STA
Example:
When Temperature 1 is over alert high value “85.00”, message “It is hot” is sent to user.
Alarm Phone receives alarm text message:
STA:000000:TM:2009/12/08/16:10;A13:85.00,It is hot
Centre receives data message:
#STH:000000,000;L:310;TM:03/04/2009,09:34;D:1;T:01;C:25;A00:0.166;A01:00000;A02:0.578;A0

;P05:00000000;P06:00000000;K01:13333330000000000;O01:0000;8F#
GPRS Ethernet Multipoint Data Logger GSX8 /GSN8 / NSX8 Technical Guide
~ 36 ~
21. Temperature Alarm Delay Time
Alarm is triggered when TEMP 1 ~ 8 temperature reading is higher or lower than user preset
values.
Alarm will only be valid when the temperature keeps at higher or lower level for the time delay.
User will only be alerted via SMS, GPRS or Ethernet only after the preset delay.
When temperature reading returns to normal level within the time delay, the alarm will be
cancelled.
Configure the Temperature Alarm Delay Time:
Command: 888888#TDY:xxxx#
Y: Temperature Channel (TEMP 1 ~ 8)
xxxx Delay Time (0000 ~ 9999 seconds)
Note: When the freezer or cold storage door is open for a while, the temperature may rise to an
alert level during the worker operation. It is useful to avoid this kind of false alarm.

22. Capturing, Logging & Upload
1. Data Capturing
It captures data from sensors every 2 seconds checking the alarm levels.
2. Data Logging
It logs the captured data into its internal memory in interval of 5/15/30/60 minutes options.
Logging interval is user programmable.
Every logging interval, one record of data will be stored in internal memory.
3. Data Upload
It uploads the logged data records in interval from 5 second up to once a day.
Upload interval is user programmable.
4. Packet Data
When “Packet Data” is selected, more than one data records will be uploaded in packet.
For example:
Logging Interval = 5 minutes Upload Interval = 15 minutes
At 8:00 am, GSX8 will upload three data records logged at 7:50, 7:55, and 8:00 am in one packet.
At 8:15 am, GSX8 will upload three data records logged at 8:05, 8:10, and 8:15 am in one packet.
5. Live Data
When “Live Data” is selected, only the last and real time data record will be uploaded.
For example:
Logging Interval = 5 minutes Upload Interval = 15 minutes
At 8:00 am, GSX8 will upload one data record captured at 8:00 am.
At 8:15 am, GSX8 will upload one data record captured at 8:15 am.
Data records at 8:00, 8:05, 8:10 and 8:15 am will be logged (saved) in internal memory. But only
data captured at 8:00 and 8:15 am will be uploaded.
6. Instant Data Upload
When GSX8 receives 999999#STATUS# command, it will capture the instant data and upload it.
That means it will upload the real time data upon this command.
However, this data record will not be logged (saved) in internal memory.

23. Testing Data Upload
A) Testing GPRS Data Upload
Free bundled testing software “GSX8_Centre” is used to test the GPRS connection, data upload and
device operation. Both UDP and TCP are supported.
Please check carefully your local network and router configuration. In the example case:
GPRS Data Logger – server network configuration
GPRS Server IP: 210.3.133.88
Server Port: 9050
Computer running the GSX8_Centre should have the following network properties.
Computer IP: 192.168.0.12
Local Port: 9050
Router Setup
When router is installed between the PC and Internet, please open the ports for UDP and TCP.
Firewall Setup
Click “GSX8_Centre” program as exception in Firewall or disable the firewall.
Open the ports defined by GSX8_Centre in the firewall setting.

B) Testing Ethernet Data Upload
Free bundled testing software “GSX8_Centre [UDP]” is used to test the GPRS connection, data
upload and device operation. Only UDP is supported via Ethernet.
Please check carefully your local network and router configuration. In the example case:
Ethernet Data Logger – its own network configuration
Device IP: 192.168.0.200
Device Port: 7005
Ethernet Data Logger – server network configuration
Server IP: 192.168.0.18
Server Port: 6005
Computer running the GSX8_Centre should have the following network properties.
GSX8 Centre IP: 192.168.0.18
Local Port: 6005
Please refer to “GSX8_Centre” manual for detail.

24. TCP and UDP Operation
(1) Data Format: TCP
This is a type of handshake data transmission with auto data recovery to ensure accuracy. When
the network signal coverage is weak, data transmission bandwidth will be huge.
(2) Data Format: UDP
This is a type of data upload without checking the data accuracy. Data transmission bandwidth
can be expected or preset in advance.
In UPD format, packet data is considered as a secure way of data transmission to ensure the
receipt of data in control centre.
GSX8 sends out the data packet to control centre (CTR IP). CTR IP replies with “@888” message
once it receives the data. GSX8 will try to resend the data packet if reply message “@888” is not
received.
(3) Data Acknowledge
When Server receives the data from GSX8, it will be acknowledged with the GSX8 current port
number and IP address. A confirmation message “@888” will be replied to GSX8. If any control is
necessary, CTR IP can send the command as “@888xxxxxxx” (e.g. @888888888#SDx:y#) to GSX8
at the same time. Usually, this method of sending command is secure because the port number
and IP address of GSX8 will remain unchanged within 60 seconds after GSX8 sends out data. It is
normal that the port number and IP address of GSX8 will only be released when GPRS Internet
connection is idle after 60 seconds.
