Introduction to the communication system
The cellular communication system enables wireless communication with LI-COR
eddy covariance systems and soil gas flux systems over cellular networks. The sys-
tem includes a Sierra Wireless AirLink RV50X cellular modem that supports 4G
LTE with fallback to HSPA+ protocols. The RV50X requires a service agreement
with a cellular provider.
Two models of RV50X are available to support global cellular networks. These are
made available from LI-COR as package 7900-715 and 7900-716 (see Table 1-1
below). Both packages include all of the hardware required to use the cellular com-
munication system with LI-COR eddy covariance and soil gas flux systems.
Table 1-1. LI-COR cellular communication packages and regions supported.
Part Number Region
7900-715 North America, South America, Europe, Middle East, Africa (NA, SA,
EMEA)
7900-716 Asia Pacific (APAC)
Arranging a data plan
Prior to using the RV50X you need to arrange a data plan with a wireless service
provider that offers cellular coverage at your site. The cellular service should be
3G/4G and be compatible with the frequencies and bands supported by the modem.
Obtain public fixed IP address. If you have access to a corporate or institutional cel-
lular account, you may need to arrange a payment plan within your institution. See
Selecting a data plan on page A-1.
Typically, the service provider will issue a SIM card (mini SIM, 2FF) that must be
installed in the modem see Introduction to the communication system above). They
AirLink Cellular Communication 1-1Section 1. Introduction to the communication system
will also provide a telephone number, IP Address, and Access Point Name (APN)
that are associated with the SIM card.

Connecting network cables
Important: Do not connect the RV50X Ethernet cable to the switch yet. Leave it
disconnected until all of the instruments are configured.
Install an Ethernet cable between the LI-7550 or LI-7500DS and the switch; and the
SmartFlux System and the switch. Leave the 30-cm Ethernet cable (part number
616-16844) from the RV50X disconnected for now.
Connecting network cables 2-7Section 2. Initial assembly
Connecting the antenna
Warning: Maintain at least 20 cm separation distance between the antenna and
your body when the RV50X is powered on.
The antenna cable is a slender coaxial cable that attaches to Cellular terminal on the
RV50X. The other end connects to the terminal on the bottom of the antenna.
Tighten the cable connections securely.
Note: When closing the enclosure, carefully fold over any cables and secure
them in the box. Use caution to ensure that the cables are not bent sharply or
pinched by the lid.
Installing the antenna in the field
Important: The antenna is a transmitter-receiver that broadcasts electromagnetic
radio 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. Never
put the antenna in an instrument enclosure, adjacent to instruments on your
instrument platform, or pointing toward instruments or cables. Maximize the dis-
tance between instruments and the antenna using the provided 4.6 m cable to
reduce the chance of radio interference.
Position the antenna so that it has clear reception and does not interfere with the
variables you are measuring. Be sure it does not shadow any radiation sensors,
obstruct the rain gauge, or obstruct eddies in an eddy covariance system.
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 50 cm into the ground and attach the antenna using the
included bracket and band clamp. In sandy, muddy, or loose soils additional sup-
port may be required to secure the mounting post.

Configuring the RV50X
Prior to using the communication modules, you have a data plan with a service pro-
vider (see Arranging a data plan on page 1-1).
Note: Sometimes networked cellular devices take a few minutes to finish booting
and to establish communications. If the devices seem unresponsive, wait a few
minutes and try again before you give up.
Connect the RV50X Ethernet cable to the switch
At this point in the setup, everything should be powered on. Connect the RV50X
Ethernet cable to the network switch then proceed through the steps in this sec-
tion.

Logging in to ACEmanager™
If you have trouble connecting to ACEmanager™, refresh the window (press F5) or
try a different web browser. Firefox, Google Chrome, and Microsoft Edge all seem
to work well.
1 Open an internet browser and enter: http://192.168.13.31:9191 in the address bar.
This will connect to the RV50X with the ACEmanager™ interface.
2 Enter the default user name and password. The user name is user .
For devices that support unique passwords, the default password is printed on the
device label. For other devices, the default password is 12345.
IMPORTANT: To protect your data and system from digital security threats, it is
important to change the password. See Changing the RV50X password on page A-8.
In addition, check the Sierra Wireless website for product information. Update
the embedded software any time updates are available.
Configuring the access point name
Your 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 provider and
request the APN associated with your wireless account. The APN will either be con-
figured automatically or it must be entered manually. To check and configure the
APN:
1 Log into ACEmanager (see Logging in to ACEmanager™ above).
2 Check the IP address.
Under Status > Cellular , the IP Address field will show the IP address. If it is 0.0.0.0
or anything other than your assigned IP address, follow these steps to set the APN.
4-2 AirLink Cellular CommunicationSection 4. Configuring the RV50X
3 Click the WAN/Cellular tab.
If you installed the card in slot 1 (see Installing the SIM card on page 2-3), select SIM
Slot 1. The APN assigned by the service provider may already be shown beside APN
In Use. If it is not, enter your assigned APN beside User Entered APN.
If the service provider also requires network authentication, on the same page,
under Advanced, enter information for Network Authentication Mode, Network
user ID, and Network Password.
4 Click Apply.
When prompted, Restart the device and log in again.
5 Repeat step 2 above and check the IP Address.
Look for your assigned IP address. It will be a numeric string of four octets (groups
of three-digit numbers >0 andSection 4. Configuring the RV50X
Viewing the RV50X IP address
You must know the RV50X IP address in order to connect with the system and any
connected device. The RV50X will have either a public Static IP address (recom-
mended) or a public Dynamic IP address (see One-way or two-way communication
with the RV50X on page A-4 for more information).
When your computer is connected to the RV50X and you are logged in, you can
view the RV50X IP Address under Status > Home > Active WAN IP Address.
Reserving an IP address range
It is useful to have an IP address range reserved so do not have to alter your com-
puter's network settings when connecting. In doing so, you will be able to connect
a computer that is configured for a dynamic IP address (assumed to be the com-
mon default setting) to the RV50X. It will be assigned an IP address by the RV50X
when connecting.
The range of 192.168.13.100 to 192.168.13.150 will work for the applications
described here. This range should not encompass the IP addresses assigned to
instruments.

Troubleshooting
Power on problems
Check the power supply wire connections to be sure all the connections are secure.
Depending upon what is included in the system, the devices typically require
between 12 and 28 VDC at 3 Amps (the maximum voltage allowed depends on
components in the system). Check the power supply voltage at the enclosure to be
sure it is adequate. With long power cables, expect some voltage drop between the
origin and end of the cable. Be sure adequate voltage is delivered to each com-
ponent in the system.
For the RV50X, be sure that both the white and red power supply wires are con-
nected to the (+) power supply. The white lead controls a switch in the RV50X that
must be activated before the RV50X will power on.
Cannot connect to RV50X using ACEmanager
l Wait a few minutes for the RV50X to initialize; it may just need to finish.
l Only connect one computer to the RV50X at a time. If you have connected mul-
tiple computers to the RV50X simultaneously, restart the RV50X and try con-
necting again.
l Restart your web browser or use a different web browser.
l Restart your computer.
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.

l Mounting hardware - periodically check the nuts, bolts, and band clamps that
secure the enclosure to the tower and tighten any loose fixtures.
l Power and communication cables - check the junctions to ensure that they
are tight. Check any cable ties that are used to secure the cables to ensure that
they have not slipped. Also look for damage from rodents and replace any dam-
aged components.

Additional considerations
This section describes several operations that may simplify your use of the RV50X.
Selecting a data plan
Prior to selecting a data plan, it is wise to consider your data transfer needs and
what you wish to accomplish while accessing the instruments remotely. For
example, do you want daily or weekly status reports on the overall performance of
the system? Do you want to download raw eddy covariance data sets directly to your
computer?
The typical raw data volume when logging compressed .ghg eddy covariance files is
about 1 MB per half hour, or about 1.5 GB of raw data in 30 days. See Table A-1
below for more details.

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 octet
ranges in value from 0 to 255. When entering an IP address, the octets are sep-
arated with a period. For example, 192.168.13.201 is a valid IP address. Some IP
address 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 you
will create with your instruments), we suggest choosing an IP address from the
private range—192.168.13.151 to 192.168.13.255. In this range, the first 3 octets,
which represent the network address, are fixed at 192.168.100. The last octet, which
represents the host address, must be different for each node on the network. For
simplicity, you can number your first device 192.168.13.201, your second device
192.168.13.202, and so on.
For example, if you have an eddy covariance flux system with an LI-7200x or LI-
7500x, LI-7700, Biomet Station, LI-8100A, and a PC, you could assign IP addresses
given in Table 3-1 on page 3-2. In addition to the IP address, you may need to set
the netmask and gateway.
The Netmask is a set of 4 octets used to separate an IP address into two parts; the
network address and the host address. If you are using LI-COR's recommended IP
address 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 local IP address (e.g.,
192.168.x.x) that has been assigned 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 make
sure you choose IP addresses that are unique and in the range of addresses sup-
ported by that network.
