Section 1.
Overview of the communication system
Communication modules enable remote wireless communication with LI-COR eddy
covariance systems, soil gas flux systems, and other systems that support Ethernet
communication. The satellite communication system (7900-720) provides access to
most sites located in most parts of the world, with the exception of the poles and
areas that are blocked from geostationary satellites.
In these instructions, the term terminal is used to refer to the Hughes 9502 satellite
modem that connects your system to the internet.
Figure 1-1. The 7900-720 communication system transfers data from a site to computer net-
works through a geostationary satellite.

Section 2.
Initial setup
This section describes how to assemble, deploy, and maintain the communication
system. The following tools are required:
lPhillips screwdriver
lBolt drivers, wrenches, or adjustable wrench (16 mm, 13 mm, and 8 mm)
lStandard slotted screwdriver (optional, instead of 8 mm bolt driver)
lPost driver for antenna post
The hardware installation will take about 30 to 60 minutes. Software configuration
will take about 15 to 30 minutes. Activating the terminal depends upon the wireless
service provider.
General steps
Note: We highly recommend that you fully assemble the system, configure your
network account, and test the system in your office or lab before deploying it in
the field.
1Arrange a data plan
Prior to using the satellite radio you need to arrange a data plan with a wireless ser-
vice provider in your area. We recommend Inmarsat BGAN M2M from Galaxy 1
Communications, but you can choose another provider if you prefer.
Important: Be sure that your service provider supports two-way communication
and that they have configured your account to allow two-way communication
through their firewall.
2-1Satellite Communication

Section 2. Initial setup
2Assemble the system
Assemble the components and install the data cables and power supply cables for
the system. See Initial assembly on the facing page.
3Configure the satellite gateway
Some settings in the gateway must be configured in order to connect to the net-
work. These are described in Configuring the communication system on page3-1.
4Configure the sensor network
The terminal and instruments must be configured to communicate with each other.
lFor a basic CO2/H2O eddy covariance system see Configure LI-7500x or LI-7200x
eddy covariance system communication on page4-2.
lTo add an LI-7700 see Configure LI-7700 communication on page4-4.
lTo add a Biomet System (Sutron) see Configure Sutron biomet system com-
munication on page4-7.
lTo add an LI-8100A Soil Gas Flux System see Connecting with an LI-8100A on
page5-1.
5Connect to the system
If everything is configured properly, you'll be able to access your eddy covariance sys-
tem from any computer on the internet and download data, connect with web ser-
vices such as FluxSuite, and modify instrument configurations.
Caution: Be careful to avoid data overage charges! You can easily transfer many
megabytes of data over the satellite terminal, which may incur large data
charges. We recommend that you disable automatic updating on your computer
when connected to the satellite system, refrain from opening web pages in your
browser when configuring your satellite connection, do not download raw data
from your site, and do not leave the connection open for longer than necessary.
Monitor your data usage. If you use Galaxy 1 Communication, register with their
billing services (https://www.ibisbilling.com) to track your data usage and set lim-
its to data transfer.
2-2 Satellite Communication

Initial assembly
This section describes the initial configuration of the communication system.
1Assemble the system.
Install the power cable first because it is difficult to access the connectors after the
terminal in installed in the enclosure. Mount the terminal in the enclosure as
shown.
Section 2. Initial setup
2-3Initial assembly

Section 2. Initial setup
2Install the Ethernet data cable and antenna cable.
A long, weatherproof Ethernet cable (part number 392-13977 for the LI-7550) con-
nects the terminal to the LI-7550 or LI-8100A Ethernet port.
3Mount the enclosure, antenna, and antenna cable.
The antenna cable is a slender coaxial cable. Tighten both cable connections
securely. Mount the antenna to a tripod or mast so it has adequate reception from
the wireless service provider. Be sure that the antenna placement does not obstruct
the wind or alter any of the variables that are measured at the site (see Mounting the
antenna on page2-6).
2-4 Satellite Communication

Mounting the communication enclosure
The enclosure mounts on a tripod, tower, or post with two mounting brackets (part
number 9979-022). It should be mounted at the base of the tower, away from instru-
ments. Cables should be secured so that strain is not applied to the cable or con-
nectors and to avoid sharp bends in the cables.
The mounting brackets and band clamps accommodate a mounting post of up to 7
cm (2.75 inches) in diameter. Hardware is included to attach the mounting plates to
the enclosure. Band clamp brackets should be attached to the mounting plates, and
then the band clamps can be inserted through the holes in the brackets and
tightened around the post, as shown in Figure 2-1 below.
Figure 2-1. Attach mounting plates to the enclosure, attach band clamp brackets to mount-
ing plates, and secure to a mast using band clamps.

Section 2. Initial setup
Mounting the antenna
Warning: Maintain at least 20 cm separation distance between the antenna and
your body when the terminal is powered on. Do not stand in front of the antenna
or place your head or body parts in front of the antenna when the system is oper-
ational.
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.
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 15 m cable to
reduce the chance of radio interference.
1Before you dig!
Check to ensure that there are no underground gas lines, electrical lines, or unex-
ploded ordnance in the vicinity.
2Drive the antenna mounting post.
Drive the post at least 18 inches (0.5 m) into the ground and attach the antenna
using the included bracket and band clamp. In sandy, muddy, or loose soils addi-
tional support may be required to secure the mounting post.
3Install the Azimuth/Elevation Bracket on the antenna.
Then install the antenna as shown in Figure 2-3 on the facing page.
