OK, one more question, do you need the RS-232 port if you only want to lock
a vcxo to the 10kHz? My guess is no, just +5 volts and ground, and take the
10kHz from pin 20 of the connector.

I have used the older Rockwell GPS stuff and they seem to need to have a
recent almanac transferred to them before they will get a fix. Rockwell
used to distribute a freebie software package that would help you deal
with all the setup stuff. It was called something like Lab_10 or Lab_X
or somesuch. The newer stuff may need less handholding.

Good Luck,
