Bill, Try a jumpers on the RS232 cable 4 to 5 and 6,8,20 together. If you have a RS232 break out box you could put it between the PC and GPSDO to see which levels change when the program is running. Stanley N4IQT

I was checking one of the units using TAC32 and I discovered that it would lock the 5 MHz to GPS ( as compared with my Z3801) when the PC software was running When I stopped the TAC32 it would lose lock. Anyone have a clue what this thing needs to stay locked.. The circuit board has a date of 1992 and it has a label that has TRN7793818 LA081WN. On the back it has connectors for; 48 Volt power Redundancy Control Remote GPS (10 pin) RS232 DCE 1 PPS out 5 MHz out. And an On Line LED Amy place I can get more information?
