●
RTCM input, in this mode, the PORT D Rx is connected to the internal GNSS receiver COM2 Rx so
differential correction data can be sent to the internal GNSS receiver for real time RTK. Please note
that in this mode, the PORT D Tx is sill connected to the GPS 1 Tx signal.
Note: Whatever the PORT D function is, the PORT D Tx is always connected to the internal GNSS
receiver COM 1. This is very useful if you would like to use the PORT D to input RTCM corrections
while sending GGA frames @ 1 Hz from the GNSS receiver.
