Getting Started
Use and Care
The radio-modem is configured as a base or rover, and can be
connected to most Trimble survey-grade and construction-grade GPS
receivers through a single serial I/O cable and power cable. When used
as a repeater, the radio-modem operates autonomously and requires
only a power and antenna connection, with no connection to the serial
port.
To achieve line-of-sight (LOS) coverage to all points in a survey area, an
SNB900 radio-modem network can include repeaters. The rovers use
the data packet from the base or repeater, whichever the rover receives
first.
The radio-modem is designed to withstand rough treatment typical of
equipment used in the field. However, it is a precision electronic
instrument and should be treated with reasonable care. It operates at
temperatures from –40 °C through +65 °C (–40 °F through 149 °F). The
casing is sealed and weatherproof.
27.1
Use and care of the internal battery

WARNING – Avoid contact with the rechargeable Lithium-ion battery if it
appears to be leaking. Battery fluid is corrosive, and contact with it can
result in personal injury and/or property damage.
To prevent injury or damage:
- If the battery leaks, avoid contact with the battery fluid.
- If battery fluid gets into your eyes, immediately rinse your eyes with
clean water and seek medical attention. Do not rub your eyes!
- If battery fluid gets onto your skin or clothing, immediately use clean
water to wash off the battery fluid.
WARNING – Charge and use the rechargeable Lithium-ion battery only in
strict accordance with the instructions. Charging or using the battery in
unauthorized equipment can cause an explosion or fire, and can result in
personal injury and/or equipment damage.
To prevent injury or damage:
- Do not charge or use the battery if it appears to be damaged or leaking.
- Charge the Lithium-ion battery only in a Trimble product that is specified
to charge it. Be sure to follow all instructions that are provided with the
battery charger.
- Discontinue charging a battery that gives off extreme heat or a burning
odor.
- Use the battery only in Trimble equipment that is specified to use it.
- Use the battery only for its intended use and according to the
instructions in the product documentation.
WARNING – The SNB900 radio-modem contains a Lithium-ion battery
and should not be disposed of with general refuse. Dispose of the SNB900
radio-modem in accordance with all local codes and regulations for
products containing lithium ion batteries. Contact your local
environmental control or disposal agency for further details.
The SNB900 radio-modem has an internal battery that supplies power
and enables it to operate when no external power is supplied. The
internal battery operates at temperatures from -20 °C through +60 °C
(-4 °F through 140 °F). If the temperature is above or below this range,
the radio-modem no longer accepts power from the internal battery
and an external power source is required. Charge the internal battery
only at temperatures from 0 °C through 40 °C (32 °F through 104 °F).
SNB900 Radio-Modem User Guide

Getting Started
To charge the radio-modem’s internal battery, connect the unit to a
15 Volt external power source and turn in on. If the SNB900 radiomodem is turned off, the internal battery will not be charged. Trimble
provides the recommended power supply (P/N 48800-00) in the
SNB900 kit.
The internal battery of the SNB900 radio-modem will gradually lose
capacity over its life. After approximately 500 charge/discharge cycles,
the battery will be down to 80 % of its original capacity. After 750 cycles,
the battery will have approximately 50 % of its original capacity.
This is true of all batteries. The cycles specified by Trimble are based on
the battery manufacturer's specifications. After 500 cycles, the battery
will still charge. However, the battery will not charge to full capacity.
When the battery can no longer take or hold a charge, please arrange
for an authorized Trimble service center to replace the battery. If the
radio-modem is operating on external power and the unit is not being
recharged, then the internal battery is not completing
charge/discharge cycles and will therefore last much longer.
If users operate their SNB900 radio-modem for 200 days a year on only
internal battery and recharge the unit each day, the radio-modem’s
internal battery will reach the 500 cycle mark after about 2½ years.
Note – The SNB900 radio-modem continues to operate from an external
power supply even when the internal battery is unusable.

Important notes
•
Make sure that each radio-modem in the network is set to the
same network number.
•
High-power signals from a nearby radio station or radar
transmitter can overwhelm radio-modem circuits. This does not
harm the radio-modem, but it can prevent it from functioning
correctly. To avoid problems, try not to use the radio-modem
within 400 meters (1300 feet) of powerful radar, television, or
other transmitters. Low-power transmitters, such as those in
portable phones and walkie-talkies, do not normally interfere
with SNB900 radio-modem operation.

31.2
Installing the SNB900 radio-modem as a base
When the radio-modem is used as a base radio, it transmits GPS
corrections from a base station receiver to rovers in a network.
To install the radio-modem as a base:
1.
If necessary, reconfigure the radio-modem serial port settings.
These settings must be the same on the radio-modem as they are
on the GPS receiver.
2.
Connect the radio-modem to the base station GPS receiver.
Note – Data that is received in CMR format on the LEMO port is reflected
out the Modem port. This means that you can monitor how much data in
CMR format is entering the SNB900 radio-modem. It also means that no
special cable is needed if you want to attach an extra radio-modem, such
as a TRIMMARK™ 3 radio-modem, to the GPS receiver.

Installing the SNB900 radio-modem as a repeater
To achieve coverage to all points in a project site, you can add up to
four repeaters to the network. Repeaters retransmit data packets in a
way that prevents mutual interference with the base and with each
other.
A rover receiver uses data packets from the base or from a repeater,
whichever it receives first. (The operation of the repeaters is
transparent to the rovers.)
To install the SNB900 radio-modem as a repeater:
34
1.
If the network has only one repeater, make sure that the SNB900
radio-modem is configured as Repeater 1. If the network has
multiple repeaters, make sure that the repeaters are numbered
sequentially. For example, this radio-modem cannot be
Repeater 3, unless there is also a Repeater 1 and a Repeater 2 in
the network.
2.
Assemble the antenna and then attach the antenna to the
antenna bracket.
3.
Attach the antenna bracket to a tripod or pole.
4.

SNB900 radio-modem is operating as a base or repeater radio, and the
3 dB whip antenna when the radio-modem is operating as a rover
radio. Both antennas antennas are provided with the radio-modem.
Safety
CAUTION – For your own safety, and in terms of the RF Exposure
requirements of the FCC, always observe the precautions listed here.
- Always maintain a minimum separation distance of 21 cm

Configuration and Installation
(approximately 8 inches) between yourself and the radiating antenna on
the SNB900 radio-modem.
- Do not co-locate the antenna with any other transmitting device.
- For mobile operation, do not allow the maximum gain of the antenna to
exceed 5 dBi.
Height
Antenna height is the single most important factor in achieving
maximum range with a radio-modem: Doubling the height of an
antenna results in an approximately 40% increase in line-of-sight range.
When installing and locating an antenna, place it as high as is legally
possible. An antenna should be higher than any surrounding hills, trees,
vehicles, buildings, or other obstructions. Try to make sure that the
radiating element of the antenna is higher than any possible
obstruction.
If you need to increase the length of the antenna cable in order to
elevate the antenna, use low loss cable.
Other objects
If possible, do not place an antenna near any other object. Metal
objects, in particular, can severely limit the efficiency of an antenna.

Omni-Directional Antennas
SNB900 Radio-Modem Antenna Range
Energy Patterns
The SNB900 radio-modem uses an omni-directional antenna that
concentrates radio frequency energy and then radiates it equally at all
azimuths in the horizontal plane.

Antenna Details
Omni-Directional Antennas
The SNB900 radio-modem uses an omni-directional antenna. The
antenna concentrates the radio frequency energy that it receives from
the radio-modem and then radiates that energy equally in all directions
in the horizontal plane. The antenna does not increase the energy that
it receives.
Note – The omni-directional antenna used with the radio-modem is not
omni-directional in the vertical plane. You must orient the antenna
vertically.
The degree to which an antenna concentrates radio frequency energy
in one direction is called directivity. Like antenna gain, directivity is
measured in decibels (dB).
High antenna gain results in high directivity, as more energy is
concentrated and then radiated in the particular plane.
4.2
SNB900 Radio-Modem Antenna Range
In an omni-directional antenna, all azimuths receive equal energy, but a
5 dB antenna radiates four times more power in the horizontal plane
than a 0 dB antenna does. In the field, this equates to almost double the
range.
However, it is the elevation and orientation of the rover antenna that
determines which antenna—the 5 dB or the 0 dB antenna—provides
the stronger signal.
