Its a good chance that the GPS receiver used is a Trimble
Acutime/Acutime 2000 or Acutime II, since they are used with most
Bancomm bus level timeing cards. (bc627AT, bc637PCI 12043/PMC/CPCI)

They usually are connected with a HD DSUB15 (like the VGA connector),
but it seems the PMC card uses a DSUB9. Check table 7-4 in


Does your DSUB9 have 12VDC(with +100mA sourcing) at pin 9? Ground at pin 3? Maybe you can
trace some pins and see if they end up going to a 422 receiver/sender? 

(Do not blame me, if you break anything...)

The present Acutime2000 has a 12pin interface, older versions had a

good luck!
