144.1.4 Additional Sensor Configuration Information (PGRMC1)The PGRMC1 sentence provides additional information used to configure the GPS sensor operation. Configurationparameters are stored in non-volatile memory and retained between power cycles. The GPS sensor will echo thissentence upon its receipt if no errors are detected. If an error is detected, the echoed PGRMC1 sentence will containthe current default values. Current default values can also be obtained by sending the sentence “$PGRMC1E” to theGPS sensor.$PGRMC1,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>,<13>*hh<1> NMEA 0183 output time 1 to 900 (sec).<2> Binary Output Data, 1 = Off, 2 = On.<3> Low Velocity Position Filter (1 = Off, 2 = On)<4> No Effect (DGPS beacon frequency: 0.0, 283.5 to 325.0 kHz in 0.5 kHz steps)<5> No Effect (DGPS beacon bit rate: 0, 25, 50, 100, or 200 bps)<6> No Effect (DGPS beacon scanning, 1 = Off, 2 = On)<7> NMEA 0183 version 2.30 mode indicator, 1 = Off, 2 = On<8> DGPS WAAS mode, W = WAAS Enabled, N = WAAS Disabled<9> Power Save Mode, P = Power Save mode, N = Normal<10> No Effect (This field is not used on this model and is included only for backward compatibility)<11> No Effect (This field is not used on this model and is included only for backward compatibility)<12> No Effect (This field is not used on this model and is included only for backward compatibility)<13> Measurement Pulse Output Auto Off Mode, 1 = Off, 2 = OnConfiguration changes take effect immediately, with the exception of Binary Output Data, which takes effect on thenext power cycle or a reset event. Send the sentence “$PGRMI,,,,,,,R” to command a reset (refer to section 4.1.2Sensor Information (PGRMI). If the GPS sensor is in the Binary data mode, it is necessary to send the followingeight-byte data stream to temporarily change the data format to NMEA 0183:10 0A 02 26 00 CE 10 03 (Hexadecimal)Then send PGRMC1 with field 2 set to turn off the Binary Output Data format.4.1.5 Additional Sensor Configuration Information 2 (PGRMC2)The PGRMC2 sentence can be used to control sensor operation parameters that are newly introduced with GPS19x.Configuration parameters are stored in non-volatile memory and retained between power cycles. The GPS sensorwill echo this sentence upon its receipt if no errors are detected. If an error is detected, the echoed PGRMC2sentence will contain the current default values. Current default values can also be obtained by sending the sentence“$PGRMC2E” to the GPS sensor.$PGRMC2,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>,<13>*hh<1> Positioning update rate, 1 = once per second, 5 = five times per second, 10 = ten times per second.<2> GPS engine dynamics mode, LOW = low dynamics, HIGH = high dynamics<3> GNSS system name, GPS, GLONASS<4> GNSS system command, ON = enable, OFF = disable (the GNSS system specified in param <3> )<5> Talker ID, AUTO, GP, GL, GN (specified talker ID use for NMEA0183 output sentences)<6> Profile ID, PR0 = no resistor wire, PR1 = with resistor wire (specifies which configuration to affect)<7> NMEA0183 output compatible with GPS17x, 0 = not compatible, 1 = force compatibleSome configuration changes take effect immediately, some take effect after power is cycled. However, the intendeduse of PGRMC2 sentence is such that the sensor is power cycled or reset (using PGRMI) after all configurationsentences have been sent to and processed by GPS sensor.Notes on use of PGRMC2 parameters:Profile ID:If the Profile ID parameter is supplied, it takes effect before any other parameters. All other supplied parameterswill be applied to the configuration profile specified by the Profile ID parameter. Also, any other configurationsentences sent to the sensor will from now on affect the specified configuration profile until it is changed again oruntil sensor is power cycled or reset. If the Profile ID parameter is not supplied then the affected configuration isdetermined by the presence of the accessory resistor wire on the Accessory-ON signal line.
