Page 3: Preface
The SV12 GPS receiver is differential-ready for applications requiring DGPS accuracy. The SV12 GPS Receiver is an upgrade to CTI’s SV8 GPS Receiver (which was a replacement for the Trimble SVeeEight Plus GPS Receiver). The SV12 GPS Receiver is manufactured by Coleman Technologies, Inc., located at 20 North Orange Avenue, Suite 300;... -
Page 4: Interface Protocols
Interface Protocols The SV12 GPS Receiver operates using either of three protocols – Trimble Standard Interface Protocol (TSIP), Trimble ASCII Interface Protocol (TAIP) and NMEA 0183 (Version 3.0). The SV12 GPS Receiver also supports RTCM SC-104 for DGPS. The factory default settings for the different factory default configurations are listed in Table 2.1-1 and Table 2.1-2. -

GPS antenna must be located outdoors with a clear view of the sky. The SV12 GPS Receiver requires an active antenna. The received GPS signals are very low power, approximately 140 dB, at the surface of the... -
Page 6: Power
The SV12 GPS Receiver is designed to be plug-and-play. The receiver requires +9 to +32 VDC. Power can be supplied to the SV12 GPS Receiver using the DC power cable. The power cable is terminated at one end with a 3-pin plastic connector which mates with the power connector on the metal enclosure. -

The receiver does not require any special power up or down sequencing. Power is supplied through the 3-pin Conxall connector. The SV12 GPS receiver provides an input for battery back-up (BBU) power to keep the receiver’s RAM memory alive and to power the real-time clock when the receiver’s prime power is turned off. -

(not allowing for SA). 3.1.3 Mounting The SV12 GPS Receiver is packaged in an anodized aluminum casing. When mounting, consider vibrations. If the vibration is within the design specifications, then the receiver can be hard-mounted. If not, select a mount that dampens the vibration enough to bring the receiver back into specification. -
Page 9: Software Interface
3.2.1 Start-up When connected to an external GPS, the SV12 GPS Receiver contains all the circuitry necessary to automatically acquire GPS satellite signals, track up to 12 GPS satellites, and compute location, speed, heading, and time. The receiver automatically begins to search for and track GPS satellite signals at power-up. -

3.2.3 Protocol Summary The SV12 GPS Receiver is shipped from the factory with the configurations listed in the following tables: Table 3.2.4-1 TSIP and NMEA Receiver Protocol Summary Setting NMEA 0183 out/RTCM SC-104 V2.1 In... - Page 11 TAIP bi-directional TSIP Data Output The Trimble Standard Interface Protocol (TSIP) is the native language for the SV12 GPS Receiver. TSIP is a binary language with a wide variety of commands and reports. TSIP reports can be output automatically, or they can be output as responses to queries. The format of the automatic reports can be easily configured.
- Page 12 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 output interval or sentence output, use TSIP...
