TRIMMARK 3 Radio Modem

1 Key features and benefits Versatile: use asbase, repeater orrover Flexible: 2, 10, or25W power output Channel spacing pro-grammable at 25 kHz Easy to use and con-figure Built-in channelselector and monitor Rugged and weather-proofTRIMMARK 3 Radio ModemSmall, rugged and versatile multichannel Radio modemThe TRIMMARK 3 radiomodem provides a convenient, ver-satile means of establishing arobust wireless data broadcast net-work for real-time, high-precisionGPS survey and telemetry applica-tions. It s a quality accessory forthe Trimble Toolbox of IntegratedSurveying rugged, compact TRIM-MARK 3 Radio Modem is designed foruse in tough environments and in avariety of situations. The single unit isusable as a base station, repeater sta-tion, or rover receiver for maximumversatility.

2 However you use it, you llappreciate its simplicity and famousTrimble reliability and the power you needThe TRIMMARK 3 Radio modemprovides selectable power outputs of 2,10, or 25 Watts to support both short-and long-range operations, conserve bat-tery life and minimize risk of interfer-ence with other systems. A 25W base unit broadcasts up to15 km (8 miles) line-of-sight, underoptimal conditions. Path obstructionsand terrain can reduce the typical effec-tive range to 10 to 12 km (6 to 7 miles).One or two additional units can be net-worked as repeater stations to extendrange, minimize base station moves, andprovide seamless coverage around localobstacles such as large buildings or typical range of a 2W repeater is 5to 8 km (3 to 5 miles). A TRIMMARK 3 Radio modembroadcasts or repeats data to Trimblesurvey-grade GPS receivers, such as theTrimble 4700 or 4800, that either con-tain an internal Radio Modem or arebeing used with a TRIMMARK TRIMMARK 3 is fully backwardcompatible with the TRIMMARK IIeradio Modem , so it can be used in bothnew and existing it to your needs The TRIMMARK 3 Radio modemcan be configured completely and easilyin the office by using the suppliedWinFLASH utility on your functions also can be configuredin the field from the front panel orfrom the Trimble Survey Controller software used with your GPS surveyreceivers.

3 The serial port communica-tion settings are easily set to match thedefault settings on the GPS can configure each broadcastnetwork to operate on one of up to20 programmed channels via a built-inchannel selector. Channel spacing ofeither or 25 kHz is programmableat the factory or by a service provider. To reduce the risk of interferencein a congested RF environment, youcan use the built-in audio speaker tomonitor activity on the selected chan-nel. The unit also can automaticallymonitor the channel using its software-selectable carrier detect function todetect other users on the channelbefore transmitting. The TRIMMARK 3 Radio modemis available as a stand-alone product aswell as in convenient base and repeaterequipment sets. Available in three fre-quency bands, the TRIMMARK 3radio Modem is designed to meet thelicensing requirements of many coun-tries around the world.
