2 Getting Started14 SNB900 Radio-Modem User Guide2.7 Use and CareThe 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.CCAUTION – Do not operate or store the SNB900 radio-modem outside the temperature range specified. Doing so can damage the instrument.27.1 Use and care of the internal batteryCWARNING – Do not damage the rechargeable Lithium-ion battery.

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.CWARNING – 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).
2 Getting Started16 SNB900 Radio-Modem User GuideTo charge the radio-modem’s internal battery, connect the unit to a 15 Volt external power source and turn in on. If the SNB900 radio-modem 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.

Download the latest upgrade from the same location as the WinFlash utility. For more information, see Step 1: Installing the WinFlash utility, page 27.2. Use the WinFlash utility to upgrade the firmware in the SNB900. In the Operation Selection dialog (see page 29), select the Upgrade radio firmware option.3.1 Installing the SNB900 Radio-Modem in the FieldYou can install an SNB900 radio-modem as a base, a rover, or a repeater.31.1 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.
SNB900 Radio-Modem User Guide 33Configuration and Installation 331.2 Installing the SNB900 radio-modem as a baseWhen 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.3. Assemble the antenna and then attach the antenna to the antenna bracket.4. Attach the antenna bracket to a tripod or pole.5. Connect the antenna cable to the radio-antenna port on the radio-modem. For the location of this port, see Figure 2.2 on page 12.6. Connect a 12 V DC power source to one of the ports on the radio-modem. Use either the LEMO connector or the 26-pin connector for this, depending on which power source you are using. 7. Make sure that the Sync and Tran messages are flashing on the radio-modem display.
3 Configuration and Installation34 SNB900 Radio-Modem User Guide30.1 Installing the SNB900 radio-modem as a repeaterTo 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: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. Connect the antenna cable to the radio-antenna port on the SNB900 radio-modem. For the location of this port, see Figure 2.2 on page 21.5. Connect a 12 VDC power source to one of the ports on the SNB900 radio-modem. You can use either the LEMO connector or the 26-pin connector for this, depending on which power source you are using.6. Make sure that the Sync, Tran, and Rcv messages are flashing on the radio-modem display.

Make sure that the Sync and Rcv messages are flashing on the radio-modem display.30.1 Installing antennasTrimble recommends that you use the 5 dB whip antenna when the 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.SafetyCCAUTION – 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
3 Configuration and Installation36 SNB900 Radio-Modem User Guide(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.HeightAntenna 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 objectsIf possible, do not place an antenna near any other object. Metal objects, in particular, can severely limit the efficiency of an antenna.

4 Antenna Details38 SNB900 Radio-Modem User Guide4.1 Omni-Directional AntennasThe 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 RangeIn 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.
