Getting StartedThis section describes how to assemble, deploy, and maintain the communicationsystem. The following tools are required:

l Phillips and Standard slotted screwdriversl Bolt drivers or wrenches: 16 mm, 13 mm, and 8 mm (5/8", 1/8", and 5/16"

approximate SAE equivalents)l Post driver for antenna post

The hardware installation will take about 30 to 60 minutes. Software configurationwill take about 30 minutes to 2 hours. Activating the gateway depends upon thewireless service provider.

Note: We recommend that you fully assemble the system, configure your net-work account, and test the system in your office or lab before deploying it in thefield.

1 Arrange a Data Plan

Prior to using the cellular gateway you need to arrange a data plan with a wirelessservice provider that offers cellular coverage at your site. See Considerations for Select-ing a Data Plan on page 3-1.

l For Verizon Wireless, the coverage should be CDMA/1xRTT/EVDO/LTE. You'llneed to establish a static, unrestricted IP address with Verizon. Prior to settingup service, retrieve the IMEI number from the modem (see Product Labels onpage 1-4). Call 800-526-3178 for business sales or 800-256-4646 for personalsales.

l For AT&T, the coverage should be AT&T GSM/GPRS/EDGE/HSPA+/LTE.You'll need a business account with AT&T. Your data plan should supportM2M communication. Ask for an "I2Gold APN". Contact your AT&T rep-resentative or Blu-Telecommunications at 877-422-2616.

Both Verizon and AT&T will provide you with a SIM card (mini SIM, 2FF) thatmust be installed inside the modem, a 10-digit telephone number that is associatedwith the SIM card and used for billing, an IP Address, and an Access Point Name(APN).

2 Install the SIM Card

The SIM card installs in the upper slot (1). Press it in until the card clicks in place,the reinstall the cover.

3 Assemble the System

Assemble the components and install the data cables and power supply cables forthe system. See Assembling the System on the facing page.

4 Configure the RV50 and Sensor Network

The gateway and instruments must be configured to communicate with each other.

l For all systems, see Log In on page 2-1, and then go to Configure Port Forwardingon page 2-5.

l For a basic CO2/H2O eddy covariance system see Configure the Eddy CovarianceSystem Communication on page 2-11.

l To add an LI-7700 see Configure LI-7700 Communication on page 2-13.l To add a Biomet System see Configure Biomet System Communication on

page 2-16.l To add an LI-8100A Soil Gas Flux System see Adding an LI-8100A on page 2-26.

5 Connect to the System

If everything is configured properly, you'll be able to access your eddy covariancesystem from any computer on the Internet and do some or all of the following:

l Connect with the FluxSuite web service (www.fluxsuite.com)l Download data from the EC system (see Automated File Transfer on page 2-21).l Download data from the LI-8100A (see Transferring LI-8100A Data on page 2-30).l Modify instrument configurations (see Connect with Remote Instruments on

page 2-20 and Connecting with the LI-8100A on page 2-30).


Assembling the SystemThis section describes how to install the communication module in the systemenclosure. You may find that it is easier to install the cables before mounting theRV50 in the enclosure. Regardless of the order that you do things, one thing isessential: Route the data and antenna cables through the openings in the bottom ofthe enclosure so that you can close the lid.

1 Install the switch and gateway in the biomet enclosure.

If not already present, install a piece of DIN rail (part number 6579-023) hori-zontally in the upper left portion of the biomet enclosure as shown below. Use twoPhillips pan head 8-32, 3/8" stainless steel screws (part number 122-00012). Installthe switch and gateway assembly on the DIN rail, as shown.


1-9Assembling the System


2 Install the power wires.

The AirLink® RV50 gateway power wire connector plugs directly into the gateway.Cut the cable to a suitable length and then strip the insulation. Twist the red andwhite wires together and connect them to a red power supply terminal (12, 13, or14) and the solid black lead to blue terminal (18, 19, or 20). The green wire is notused.The Ethernet switch connects to the power supply using black and red leads fromthe spares kit. Install the red lead between the switch terminal labeled 2 and a redpower supply terminal (12, 13, or 14). Install the black lead between the switch ter-minal labeled 1 and blue power supply terminal (18, 19, or 20).

3 Install the data cables.

One 15 cm (0.5 ft) Ethernet cable (part number 616-16844) connects the networkswitch to the cellular gateway. A red Ethernet cable (included with the Sutron) con-nects the network switch to the Sutron datalogger. A weatherproof Ethernet cableconnects the Ethernet terminal on the LI-7550 or the LI-7500DS to the switch.Your system may include one of the following cables: 392-13990, 392-13977, 392-16699, or 392-13967.


4 Install the antenna.

The antenna cable is a slender coaxial cable that attaches to a 90° adapter and theCellular terminal on the gateway. The other end connects to the terminal on thebottom of the antenna. Tighten the cable connections securely. See Mounting theAntenna on the next page for details.

Note: When closing the Biomet system lid, carefully fold over any cables andsecure them in the box. Use caution to ensure that the cables are not bentsharply or pinched by the lid.


1-11Assembling the System


Mounting the AntennaWarning: Maintain at least 20 cm separation distance between the antenna andyour body when the gateway is powered on.

Position the antenna so that it has clear reception and does not interfere with thevariables you are measuring. Be sure it does not shadow any radiation sensors,obstruct the rain gauge, or obstruct eddies in an eddy covariance system.

Important: The antenna is a transmitter/receiver that broadcasts electromagneticradio signals. Some electronic devices, data recorders, and sensors may be sus-ceptible to radio interference from this antenna. Therefore, it is important to pos-ition the antenna at a reasonable distance from sensors and data recorders. Neverput the antenna in an instrument enclosure, adjacent to instruments on yourinstrument platform, or pointing toward instruments or cables. Maximize the dis-tance between instruments and the antenna using the provided 15 m cable toreduce the chance of radio interference.

1 Before you dig!

Check to ensure that there are no underground gas lines, electrical lines, or unex-ploded ordnance in the vicinity.

2 Drive the antenna mounting post.

Drive the post at least 18 inches (0.5 m) into the ground and attach the antennausing the included bracket and band clamp. In sandy, muddy, or loose soils addi-tional support may be required to secure the mounting post.

Figure 1-1. Antenna mounting configuration. Drive the post at least 45 cm (18 inches) intothe ground or more in sandy, loose, or muddy soil.

Securing CablesCommunication and power cablesshould be secured so they do not applystrain to connectors and junctions.Secure the cables to the strain-reliefplugs as shown.


1-13Securing Cables

Section 2.Configuring the Communication System

Prior to using the communication modules, you must arrange a data plan with acellular provider that provides communication with either CDMA or GSM pro-tocols. If you have access to a corporate or institutional cellular account, you mayneed to arrange a payment plan within your institution.

Note on patience: Sometimes networked cellular devices take a few minutes tofinish booting and to establish communications. The devices may seem unre-sponsive, requiring you to wait a few minutes. Think of it like a new marriage—it might take some time to learn how to communicate, and it probably will tryyour patience. Like in marriage, your patience and commitment will pay off inthe end.

Log InIf you have trouble connecting to ACEmanager™, refresh the window (press F5) ortry a different web browser. Firefox, Google Chrome, and Microsoft Edge all seemto work well.

1 Connect the gateway to your computer with a standard Ethernet cable (part number 616-06116)and power it up.

2 In an Internet browser, enter: http://192.168.13.31:9191 in the address bar.

This will connect to the gateway with the ACEmanager™ interface.3 Enter the default user name and password:

l User Name: userl Password: 12345



IMPORTANT: To protect your data and system from digital security threats, it isimportant to change the password. See Changing the Gateway Password onpage 3-8. In addition, check the Sierra Wireless website for product information.Update the embedded software any time updates are available.

Configure the Access Point NameYour cellular service provider will provide you with an Access Point Name (APN)when you sign up for cellular service. If not, you may need to contact the providerand request the APN associated with your wireless account. The APN may be con-figured automatically or need to be entered manually. To check the APN:

1 Power on the gateway and connect the network cable to your computer. Log into ACEmanager(see Log In on the previous page).

2 Check the IP address.

Under Status > Cellular, the IP Address field will show the IP address. If it is 0.0.0.0or anything other than your assigned IP address, follow these steps to set the APN.


3 Click theWAN/Cellular tab.

Under Network Credentials GSM > APN Type, change Select From List to UserEntry and enter the assigned APN into the Select From List field. If you do not havean APN from the cellular provider, change the APN Type to broadband.

4 ClickApply.

When prompted, Restart the device and log in again.5 Repeat steps 2 above and check the IP Address.

The gateway should display your assigned IP address. It will be a numeric string offour octets (groups of three-digit numbers >0 and <255 like 192.168.13.100). It willtake several minutes for the gateway to collect all the needed information and estab-lish a connection with the network—patience is a virtue in all things, and espe-cially when configuring the gateway.

6 Verify the connection.

If your IP address, APN, and phone number are given, the connection is con-figured properly.


2-3Configure the Access Point Name


View the IP AddressYour wireless gateway will have either a public Static IP address (recommended) ora public Dynamic IP address (see One-way or Two-way Communication? on page 3-4for more information). Regardless of which it has, you will need to know the IPAddress in order to connect with the device and any sensors that are connected to it.

When your computer is connected to the gateway and you are logged in (assumingthe gateway is registered and configured), you can view the IP Address under theStatus > Home > Cellular IP Address tab.

Configure Port FilteringInbound Port Filtering can protect the instruments at the site from nefarious hack-ing attempts over the network. For this reason we recommend blocking port 22using the filtering option described here.

1 Connect to the gateway as described in Log In on page 2-1.

2 Enable Port Filtering.

In ACEmanager, click Security > Port Filtering - inbound.3 For Inbound Port Filtering Mode choose Blocked Ports.

4 ClickAddMore and set user Start Port: 22 and End Port: 22.


Configure Port ForwardingPort forwarding allows remote computers and devices to connect to a specificdevice within a Local Area Network. Port forwarding must be enabled in the cel-lular gateway to allow you to communicate with the devices that are connected toit (such as an LI-7500DS or other instrument).

1 Connect to the gateway as described in Log In on page 2-1.

2 Click Security > Port Forwarding.

3 Set Port Forwarding to Enable.

About Sensor NetworksA basic knowledge of network principles will help you exploit the power of net-worked sensors—and help ensure successful deployment of your system. In this sec-tion we describe some basic concepts of networking that may help you understandhow the system works, how to configure communication in the system, and howto solve communication problems.

LI-COR eddy covariance systems and soil gas flux systems communicate usingstandard Internet communication protocols. In an eddy covariance system that hasmultiple instruments, the devices will create a Local Area Network (LAN). Thelocal area network allows the devices to communicate with each other like com-puters on the Internet.

Each instrument in the flux system (including the LI-7500x, LI-7200x, LI-7700,Biomet system, and LI-8100A) can be added to the LAN. In order to communicatewith other devices in the network, each instrument must be given a unique Inter-net Protocol (IP) address within the LAN. When configured for cellular com-munication, the wireless communication system will get a unique IP address,which isolates the instruments from the global Internet in a LAN, while allowingaccess to the instruments from computers on the Internet.

The IP Address is a number that uniquely identifies each device on the network.The address is composed of a set of four numbers called "octets", where each octetranges in value from 0 to 255. When entering an IP address, the octets are sep-arated with a period. For example, 192.168.100.2 is a valid IP address. Some IPaddress ranges have been set aside for private use, and are typically used by organ-izations for internal networks. For a peer-to-peer network (such as the network youwill create with your instruments), we suggest choosing an IP address from theprivate range—192.168.100.0 to 192.168.100.255. In this range, the first 3 octets,which represent the network address, are fixed at 192.168.100. The last octet, whichrepresents the host address, must be different for each node on the network. Forsimplicity, you can number your first device 192.168.100.1, your second device192.168.100.2, and so on.

For example, if you have an eddy covariance flux system with an LI-7200x orLI-7500x, LI-7700, Biomet Station, LI-8100A, and a PC, you could assign IPaddresses given in Table 3-1 on page 3-1. In addition to the IP address, you mayneed to set the netmask and gateway.


3-3About Sensor Networks


The Netmask is a set of 4 octets used to separate an IP address into two parts; thenetwork address and the host address. If you are using LI-COR's recommended IPaddress range, the netmask should be set to 255.255.255.0 for all instruments.

The Gateway is a node that routes traffic to another network. For cellular com-munication systems, the gateway should be set to the IP address that has beenassigned to the router.

Note: LI-COR sensors always use static IP addresses when in wireless com-munication systems. Therefore, when connecting to an existing network makesure you choose IP addresses that are unique and in the range of addresses sup-ported by that network.

One-way or Two-way Communication?The network settings can be configured for one-way communication, whichenables you to recieve status information from the instruments, or two-way com-munication, which enables you to recieve raw and processed data and send con-figuration files.

One-way Communication: Status Notifications OnlyIf you simply wish to check the status of your system, use a Dynamic IP Address.This setting is often referred to as Obtain an IP address automatically and ObtainDNS server address automatically. This will enable the system to send statusreports. See Using a Dynamic IP Address on page 3-6.

Two-way Communication: Data and Configuration FilesIf you wish to send configuration files to the system, you will have two options:

l Option 1: Assign a Static IP Address and enter the required information (seeUsing a Static IP Address on page 3-6).

l Option 2: Configure the system to have a Dynamic IP Address and use aDynamic DNS service to keep track of the gateway's IP address (see Using aDynamic IP Address on page 3-6).


About IP AddressesWhen connected to the Internet using a cellular gateway, the cellular gateway andeach networked instrument in the system will get a unique IP (Internet protocol)address. You will communicate with the system using the IP address of the cellulargateway.

IP addresses are either static (fixed) or dynamic (assigned by a service provider ordevice; likely to change when the system restarts). You can configure your devicesto use either static or dynamic IP addresses. The choice depends upon your object-ives, region, and resources (e.g., money and time). In either case, the IP addressshould be a public IP address.

When should you use a static IP address?Use a static IP address if one is available for purchase and it is affordable.

l Advantages: The cellular gateway will always have the same IP address, so youwill be able to connect with your devices from any networked computer byentering the IP address. A static IP address is the simplest way to ensure thatyour devices can communicate with each other.

l Disadvantages: Static IP addresses are not available in some countries andregions. Static IP addresses may cost $500 for an unlimited time, depending onthe service provider. They may be available from your cellular carrier. See Table3-3 on the next page for a list of Static IP address providers.

When should you use a dynamic IP address?Use a dynamic IP address when you only need to get information from the devices,but never send information to the device (i.e., receive status updates but not sendconfiguration updates), or when a static IP address is not available or if it is toocostly.

l Advantages: There are no additional fees as with the static IP address. DynamicIP addresses are not limited to regional availability.

l Disadvantages: Since the IP address is assigned by the Internet service provideror device, it may change frequently. You will need to enlist the services of aDynamic Domain Name Server (DDNS) to connect with your instrumentsonline. A DDNS makes a dynamic IP address act like a static IP address by

tracking the device IP address when it changes, and providing it to you. Severalcompanies provide this service free of charge or at low cost. See Using a DynamicIP Address below for a list of DDNS service providers.

Using a Static IP AddressThe gateway will probably configure its IP address automatically when you installthe SIM card (and enter the APN, if needed). If it does not, be sure that you haveacquired a static IP address from the cellular service provider and follow these steps.

Table 3-3. Static IP Address service providers.

Using a Dynamic IP AddressA dynamic IP address is one that is assigned—typically by a service provider—andthat may change whenever the device restarts. The trouble this presents is that youmust know the IP address of your gateway anytime you want to connect to it. If theIP address has changed, you probably do not know what the new IP address is. For-tunately, you can use online services to resolve a dynamic IP address of the wirelesssystem.

To use a dynamic IP address, first set up a Dynamic DNS (DDNS) with a serviceprovider from the list of supported providers. You may need to create an accountwith the DDNS provider. Table 3-4 below lists free and paid DDNS service pro-viders.

MaintenanceWhen visiting the field site, check over the system to ensure that everything isinstalled properly and that the components are free of damage. Check the fol-lowing:

l Mounting hardware - periodically check the nuts/bolts and band clamps thatsecure the enclosure to the tower and tighten any loose mounts.

l Power and communication cables - check the junctions to ensure that theyare tight. Check any cable ties that are used to secure the cables to ensure thatthey have not slipped. Also look for damage from rodents and replace any dam-aged components.


Section 4.Troubleshooting

Power On ProblemsThe devices require between 10 and 28 VDC at 3 Amps. Check the power supplyvoltage to be sure it is adequate. Check the power supply wires to be sure all theconnections are secure.

For the Sierra Wireless RV50, be sure that both the white and red power supplywires are connected to the (+) power supply. The white lead controls a switch inthe gateway that must be activated before the gateway will power on.

Cannot Connect to Cellular Gateway UsingACEmanager™ Control Panel

l Wait a few minutes for the gateway to initialize. Patience is a virtue in allthings—especially when using cellular gateways.

l Only connect one computer to the gateway at a time. If you have connectedmultiple computers to the gateway simultaneously, restart the gateway and tryconnecting again.

l Restart your web browser or use a different web browser.l Restart your computer.l Be sure the gateway has finished starting up and connecting.l Check the Ethernet cable to be sure it is good. Swap it out with another one to

test it.l Check the user name and password.


Section 4. Troubleshooting

Cell Reception is Poor (>-110 dBm)l Out of cellular range. Try to reposition the antenna to get better reception.l Antenna wires not tightened properly—check the cable connections and tighten

them.

I can connect to the Internet through the gateway,but I can't connect to my instruments over theInternet

This is likely a result of improperly assigned Access Point Name (APN) from thenetwork provider or improperly configured port forwarding in the wireless gateway.

l Check your gateway APN (see Configure the Access Point Name on page 2-2). Didthe service provider give you an APN? Is it set properly? If not, you may need toget one and configure it.

l Check your port forwarding configuration, as described in Configure Port For-warding on page 2-5.
