1.0 PREFACE The Global Positioning System (GPS) is a sa tellite based navigation system operated and maintained by the U.S. Government. The G PS consists of a constellation of 24 satellites providing world-wide, 24 hour, three dimensi onal (3-D) coverage.
acquires a position fix with minimal delay after power cycling. The following information is necessary to help decrease th e tim e to track satellites after power-up and is stored in RAM when backup p.
TAIP TAIP is an easy-to-use ASCII protocol de veloped by Trimble for vehicle tracking. The user can set up polling schemes and mark G PS m essages with unique identifiers. The TAIP messages and output rates are user selectable and can be configured to operate on either Port 1 or Port 2.
earth. Trimble’s active antennas include a pream plifier that filters and amplif ies the GPS signals before delivery to the receiver. There are two GPS antennas offered by Cole man Technologies, Inc. (1) magnetic m ount antenna and (2) bullet antenna.
2. Connect the antenna cable to the receiver. Push the connector onto the MCX connector on the receiver. To remove the antenna cable, pull the antenna connector off of the MCX connector. 3. Place the antenna so that it has a clear view of the sky. 4. Using the DC power cable, connect to the 3-pin power connector on the receiver.
Note – 3.0 V is the minimum allowable voltage for battery backup. When the power output drops below 3.0 V, the real-time cloc k may not operate over the specified full temperature range and this can significantly extend the time to first fix. Power requirements are listed in Table 3.
3.2 Software Interface This section describes the SV12 GPS Receiver software interface, the start-up characteristics for the different interface protocols, a description of the receiver operating modes, and a brief description of the interface protocols.

Table 3.2.4-3 TAIP Receiver Protocol Summary Setting Default NMEA 0183 out/RTCM SC-104 V2.1 In Port 1: 4800 baud none-8-1 TAIP bi-directional Port 2: 4800 baud none-8-1 TSIP Data Output The Trimble Standard Interface Protocol (TSI P) is the native language for the SV12 GPS Receiver.
Note – Although the SV12 GPS Receiver supports the seven NMEA sentences that contain GPS information, the factory default setting for the receiver only outputs the GGA and VTG data strings. To change the out put interval or sentence output, use TSIP Command Packet 0x7A.
