I am sure this has been covered, but I did have much luck in the archives.
I have an HP Z3805A with the nice faceplate and 6 leds on the front. I also have a Z3801A also with 6 LEDs. What is the difference in the com ports? The Z3805A works fine with a standard 25pin to 9 pin adapter. The Z3801 does not. The Z3801 was my first GPSDO and I once had it working until the oscillator crapped out. I recall I might have had a special com port wiring on that unit but my memory fails me. Can someone point the differences between the two and can someon provide the pinouts for the Z3801A. Also, my Z3805A is on the fritz. Things went south after a lightning storm, but I can't be sure the two are related. I looked at it a few days after the storm and it wasn't working. The status says it is tracking two, sometimes three sats, but it just doesn't lock. I tried two different antennas, no difference. Is the GPS damaged possibly? Any clues?
