Page 5: Introduction
The GLONASS system is operated by the government of Russia, which is solely responsible for its accuracy and maintenance. Although the GPS 19x HVS is a precision electronic NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted, and therefore become unsafe. Use these products at your own risk. To reduce the risk, carefully review and understand all aspects of these Technical Specifications before using the GPS 19x HVS. -
Page 6: Overview
1.2 OVERVIEW The GPS 19x HVS is an embedded receiver and an antenna. Based on the proven technology found in other Garmin GPS receivers, the GPS 19x HVS tracks multiple satellites at a time while providing fast time-to-first-fix, precise navigation updates from once per second up to ten times per second, and low power consumption. This generation of GPS sensors includes the capability of FAA Wide Area Augmentation System (WAAS) differential GPS. -

The unit accepts TIA-232-F (RS-232) level inputs and transmits voltage levels from ground 3.3 V, TIA-422 (RS-422) polarity. 2.1 GPS 19X HVS PINOUT GPS 19x HVS... - Page 10 GPS 19x antenna, and connect the white/orange wire (Rx/B) to ground. Note: The orange (accessory on) wire is used when wiring the GPS 19x to a Garmin chartplotter, or other NMEA 0183 device that has a defined accessory signal wire. If you are wiring the GPS 19x to a device that does not have an accessory signal wire, the orange wire from the GPS 19x should be connected to ground.

“GRM” indicate that it is Garmin’s proprietary sentence. The letter (or letters) that follow the characters “$PGRM” uniquely identifies that particular Garmin proprietary sentence. It is also possible to configure the GPS 19x HVS to transmit binary data information over its serial interface. See Appendix B: Garmin Binary Output Format for details. -

Page 14: Additional Sensor Configuration Information (Pgrmc1)
4.1.4 Additional Sensor Configuration Information (PGRMC1) The PGRMC1 sentence provides additional information used to configure the GPS sensor operation. Configuration parameters are stored in non-volatile memory and retained between power cycles. The GPS sensor will echo this sentence upon its receipt if no errors are detected. If an error is detected, the echoed PGRMC1 sentence will contain the current default values. -
Page 15: Output Sentence Enable/Disable (Pgrmo)
The PGRMO sentence provides the ability to enable and disable specific output sentences and assign them high or low transmission priority. The following sentences are enabled at the factory for the GPS 19x HVS: GPGGA, GPGSA, GPGSV, GPRMC, GPVTG and PGRMT. -
Page 16: Transmitted Nmea 0183 Sentences
Sending the sentence “$PGRMO,,G” will cause the COM port to change to Garmin Data Transfer format for the duration of the power cycle. The Garmin mode is required for GPS 19x HVS series product software updates. 4.2 TRANSMITTED NMEA 0183 SENTENCES The subsequent paragraphs define the sentences that can be transmitted by the GPS 19x HVS. -
Page 17: Transmitted Time
The maximum number of fields allowed in a single sentence is 82 characters including delimiters. Values in the table include the sentence start delimiter character “$” and the termination delimiter <CR><LF>. For the GPS 19x HVS, the factory set defaults result in a once per second transmission at the NMEA 0183 specification transmission rate of 4800 baud. -
