TABLE A-3. PGRMO Output Sentence Enable/Disable
$PGRMO,1,2,*hhCRLF
1 Target Sentence description (e.g., GPVTG)
2 Target Sentence Mode, where:
0 = disable specified sentence
1 = enable specified sentence
2 = disable all output sentence (except PSLIB)
3 = enable all output sentences (except GPALM)
4 = restore factory default output sentences
PGRMO Notes:
1. If the target sentence mode is 2 (disable all) , 3 (enable all) or 4 (restore
defaults), the target sentence description is not checked for validity. In this
case, an empty field is allowed (e.g., $PGRMO,,3), or the mode field may
contain from 1 to 5 characters.
2. If the target sentence mode is 0 (disable) or 1 (enable), the target sentence
description field must be an identifier for one of the sentences that can be
output by the GPS sensor.
3. If either the target sentence mode field or the target sentence description
field is not valid, the PGRMO sentence will have no effect.
4. $PGRMO,GPALM,1 will cause the GPS sensor to transmit all stored
almanac information. All other NMEA 0183 sentence transmission will be
temporarily suspended.
5. $PGRMO,,G will cause the COM 1 port to change to GARMIN data
Transfer format for the duration of the power cycle. The GARMIN mode
is required for GPS 16/17 series product software updates.
