I got it, header j3, pin1 +15(green), pin2 +5(red), pin3 acom, pin 4 acom(blue), pin 5 test ref, pin 3 and 5 should be jumpered. Now, i just need the pinout for the ocxo. Its a McCoy mc833x4-003w that i picked up on ebay for a song and a dance. I need to find the pinouts so i can throw it on the counter first to see how it compares to my gpsdo.
