Thanks, Do you think I am right on the everything else, the GRX and the GTX ( does rx connect to tx or does rx connect to rx)

The GPPS is likely designed to connect to a GPS Pulse Per Second - which is likely the measured pulse thing...
Caveat - I know nothing about the RTCM, but I do know some about interfacing GPS modules for other purposes.

I am now going to solder the Garmin 18x GPS to the DB15 connector for the RTCM.
I am a little confused by the labels so is this pinout correct?
RTCM --- GPS
GRX ----- TXD GPPS ---- GND ------ GND +5V ----- Input Voltage GTX ----- RCV RST -----
Is this correct? There is also a "measurement Pulse Output" wire, but I don't know what to do with that.
