port. Again, consult your GPS manual for the name of this pin; names vary by vendor.
Also, make sure this pin will accept an RS232 signal (+ and – voltages).
Alternate GPS Input
In the MT1200, an alternate input for GPS data is available. This input is pin 2 on the
MT1200 “Radio” port, and is enabled with the command GPSPORT. A data signal
ground is also required, which is pin 6 or pin 9 on the “Radio” port.
Note: The default function for pin 2 on the radio port is XCD (external carrier detect). If
pin 2 has been connected to a GPS device, and GPSPORT has been configured for
GPS input on this pin, the XCD function is not available.
