Chapter 5 - I/O Commands
NMEA PROTOCOL SELECT (@@Ci)
Applicability: M12+ Positioning Receivers
This command causes the M12+ positioning receiver to change the serial data format on the
primary port from Motorola binary to NMEA 0183. The baud rate of the port is switched from 9600
to 4800 and input commands are recognized in NMEA format only. Note that the default mode of
all of the NMEA output messages is off. To initiate NMEA output, the NMEA input commands
detailed in the following pages must be utilized.
NOTE: There is no binary response to this command by the receiver. The receiver immediately
switches to NMEA protocol and awaits NMEA commands.
Legacy Code Compatibility: The @@Ci command has been implemented in an identical fashion
on virtually all Motorola VP, GT+, and M12 Oncore positioning receivers.
