3 Configuring the SNR90014 SNR900 Operation Manual3.3.3 NetworkTo change which GPS base station a SNR900 listens to, set the Network number. The SNR900 offers 40 different Network numbers.Note – If you only have one GPS base station on your site, set all your radios to the same Network number. If you have more than one GPS base station on your site, each GPS base station must be on a separate radio network. Select a different Network number for each radio network.When you initially set up a radio network for your site, configure a rover to the Network number you require and listen to see if anyone is currently using this network in your area. If the rover sync light glows, you must select a different Network number for your site. This will avoid interfering with the other network user. 3.3.4 ModeEach radio in a SNR900 network can be set to one of three operational modes:• GPS Base – when it is connected to the base station GPS receiver that is generating CMR corrections• Rover – when it is mounted on a machine that is connected to a receiver required to generate RTK positions• Repeater – when it is used in a network to increase coverageNote – A network can have many rovers but only one base radio. It can also have up to four repeaters, each uniquely identified by a different repeater number (#1, #2, #3, and #4). Repeaters can be chained two in a row. 3.3.5 Serial Port Baud Rate and ParityThe serial port baud rate list and the serial port parity setting list configure the baud rate and parity of the radio port that is connected to the GPS receiver. Set the baud rate to 38400 and the parity to None.SNR900.book Page 14 Friday, December 3, 2004 2:02 PM

4 Installing the SNR900 Network18 SNR900 Operation Manual4.1 IntroductionTrimble recommends that you read this chapter before installing your SNR900 radios.4.2 Physical DescriptionThe SNR900 radio-modem is encased in a rugged, waterproof metal case. It has an antenna mount on the top cap, and a connector and LED on the bottom cap. The physical aspects of SNR900 hardware are outlined below, followed by details covering interface connections and antenna installations. 4.2.1 Connectors and IndicatorsThe SNR900 bottom cap is fitted with an 8-pin male Bendix connector and an LED indicator light. See Figure 4.1.Figure 4.1 SNR900 bottom capPower I/O connector (8-pin male Bendix)Data/Powerindicator LEDSNR900.book Page 18 Friday, December 3, 2004 2:02 PM
SNR900 Operation Manual 19Installing the SNR900 Network 4The LED can be orange and/or green depending on the situation, as shown in Table 4.1.Note – The top cap of the SNR900 has an antenna contact tip. The tip is designed for maximum efficiency and very low loss. Please take care not to damage this tip. Keep the low-profile antenna or flexible antenna base screwed on to the top of the radio when storing the SNR900, see page 32. Figure 4.2 shows the top cap.Table 4.1 Operational statusLED Color StatusOrange (solid) Power is available.Orange and green (both solid) With the SNR900 configured as a base radio (that is, a source of GPS), power is available. The base is always considered to be synchronized. “Sychronized” means that the radio can receive and transmit data. With the SNR900 configured as a repeater or rover, power is available and the radio is synchronized. Even if the radio is synchronized, the radio may not be receiving data.Orange and green (both flashing at 1 Hz together)Radio is in flashloader mode. To resolve this, turn the power off and on. If this mode repeats when the radio is turned back on, reload the firmware.SNR900.book Page 19 Friday, December 3, 2004 2:02 PM

4 Installing the SNR900 Network28 SNR900 Operation ManualThe DB-9 connectors can connect to a GPS receiver and to a PC at the same time. This is particularly useful for troubleshooting. This cable requires its own power for the radio. It has no Conxall connector for the MS750 GPS receiver. You can connect it to the MS750 with the hammerhead connector B1/B2 cable PN 37382 that comes with the base (reference) station kit. The cable has a TA-3 connector for power to the radio only. The MS750 must be powered separately with the cables provided in the base station. See Figure 4.8.Figure 4.8 Service cable assembly (PN 40942-03, -40, -99)The 1 m (3 ft) cable (PN 40942-03) is designed for use with a survey backpack.1-shell 5-pinLemo powerDB-9 GPSDB-9 I/O 8-pin BendixTo SNR900To PC fordata orconfigurationTo cablePN 37382 SNR900.book Page 28 Friday, December 3, 2004 2:02 PM

SNR900 Operation Manual 31Installing the SNR900 Network 44.5 Antenna DescriptionThe standard SNR900 antenna is a 0 dB, low-profile antenna. An optional infrastructure installation kit comes with an antenna base and 5 dB whip antenna tip. The 5 dB antenna measures 81 cm (32") in length, including the base. See Figure 4.11.

4 Installing the SNR900 Network32 SNR900 Operation Manual4.5.1 Antenna ConsiderationsNote – Please use care when removing the radio antenna. The SNR900 antenna contact tip is designed for maximum efficiency and very low loss. To maintain its integrity, do not remove the top cap from the radio housing.Make sure that you mount the base and repeater radios as high as possible. An increase in the antenna height increases your line of sight and is the most effective way to increase the radio’s range. Figure 4.12 shows the optional infrastructure antenna mounting for the SNR900.Figure 4.12 Infrastructure antenna mountingTop capO-ringFlexibleantennabase5 dB tipMake sure that you fit the O-ringsthat are providedO-ringSNR900.book Page 32 Friday, December 3, 2004 2:02 PM

SNR900 Operation Manual 35Technical Specifications A1 Power consumption, as well as the permissible number of repeaters in a network, depends on the information content and wireless data rate (that is, CMR vs RTCM SC-104 Ver. 2.x packets at 1 Hz epoch rates).2 Broadcast frequency and radiated power are regulated by countries-of-use. These are unique on a per country basis. The broadcast frequencies, and country-of-use for the radio-modem must be specified at time of order.Radio-modem performanceRangeOptimalTypicalFrequency rangeNetworksTransmit powerWireless data ratesModes10 km (6 miles), line-of-sight3–5 km (2–3 miles)Varies with terrain and operating conditions.
