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.
Current default values can also be obtained by sending $PGRMC1E<CR><LF> or
PGRMC1E*3F<CR><LF> to the GPS sensor.
$PGRMC1,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>,<13>*hh<CR><LF>
<1> NMEA 0183 output time 1 to 900 (sec).
<2> Garmin Binary Output, 1 = Off, 2 = On.
<3> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<4> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<5> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<6> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<7> NMEA 0183 version, 1 = version 2.20 (factory default), 2 = version 2.30
<8> DGPS WAAS mode, A = Automatic, W = WAAS Only , R = RTCM Only, N = None (DGPS
Disabled)
<9> Power Save Mode, P = Power Save mode, N = Normal
<10> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<11> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<12> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
<13> PPS Auto Off Mode, 1 = Off, 2 = On
<14> No Effect (This field is not used on the GPS 15xH/15xL and is included only for
compatibility with other models.)
Configuration changes take effect immediately, with the exception of Garmin Binary Output,
which takes effect on the next power cycle or a reset event. Send the sentence
$PGRMI,,,,,,,R<CR><LF> or $PGRMI,,,,,,R*3F<CR><LF> to command a reset (refer to 4.1.2) . If
the GPS sensor is in the Garmin binary data mode, it is necessary to send the following eight-
byte data stream to temporarily change the data format to NMEA 0183:
10 0A 02 26 00 CE 10 03 (Hexadecimal)
Follow by sending a PGRMC1 sentence that turns off the Garmin Binary Output format:
$PGRMC1,,1<CR><LF> or $PGRMC1,,1*4B<CR><LF>
4.1.5 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.
This sentence is not intended for turning on and off sentences as a means of polling while the
receiver is in use; instead, it is intended to allow systems integrators to initialize the GPS receiver
so it produces only the sentences required by the target application.
