1) If the target sentence mode is ‘2’ (disable all) or ‘3’
(enable all), 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 being output
by the GPS 35/36.
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,GPLAM,1 will cause the sensor board to
transmit all stored almanac information. All other
NMEA sentence transmission will be temporarily
suspended.
4.2 NMEA TRANSMITTED SENTENCES
The subsequent paragraphs define the sentences which
can be transmitted on TXD1 by the GPS 35/36.
4.2.1 Sentence Transmission Rate
Sentences are transmitted with respect to the user selected
baud rate.
The GPS 35/36 will transmit each sentence (except where
noted in particular transmitted sentence descriptions) at a
periodic rate based on the user selected baud rate and user
selected output sentences. The GPS 35/36 will transmit the
selected sentences contiguously. The contiguous
transmission starts at a GPS second boundary. The length
of the transmission can be determined by the following
equation and tables:
