3 GPS 10X SOFTWARE INTERFACE The interface protocol design of the GPS 10x product is based on the National Marine Electronics Association’s NMEA 0183 ASCII interface specification. This standard is fully defined in NMEA 0183, Version 2.30. Copies may be obtained from NMEA, http://www.nmea.org/. In addition to the standard NMEA 0183 sentences, the GPS 10x may also be configured to transmit information over their serial interface using NMEA 0183 compliant Garmin proprietary sentences. These

3.1.2 Output Sentence Enable/Disable (PGRMO) The $PGRMO sentence provides the ability to enable and disable specific output sentences. The following sentences are enabled at the factory: GPGGA, GPGSA, GPGSV, GPRMC, and PGRMT. $PGRMO,<1>,<2>*hh <1> Target sentence description (e.g., PGRMT, GPGSV, etc.) <2> Target sentence mode, where: 0 = disable specified sentence 1 = enable specified sentence 2 = disable all output sentences 3 = enable all output sentences (except GPALM)

3.2.2 Transmitted Time The GPS sensor outputs UTC (Coordinated Universal Time) date and time of day in the transmitted sentences. Before the initial position fix, the on-board clock provides the date and time of day. After the initial position fix, the date and time of day are calculated using GPS satellite information and are synchronized with the one-pulse-per-second output. The GPS sensor uses information obtained from the GPS satellites to add or delete UTC leap seconds and correct the

APPENDIX A: BINARY PHASE OUTPUT FORMAT In binary phase output mode, GPS 10x series products will transmit two types of packets once per second. One record contains primarily post-process information such as position and velocity information. The second record contains receiver measurement information. Refer to the Garmin Device Interface Specification for details on how to form and parse Garmin packets. At the time of this printing, these specs are available from the technical suppport
