Hi Fred, The PPS in/out of the PRS10 do not appear to connected to the TS2700 logic board. I'll look back the the documentation for step #22. I'm not looking for a PPS that's just a frequency/period reference, but instead places the PPS at the GPS PPS position. Perhaps the TS2700 is already do it, but so far, I've only seed evidence that it's a frequency reference. I was a bit dismayed that selecting the TOD output as either NTP or Cisco results in an "unimplemented" error message. As for the connections between the PRS10 in the TS2700, here's a pinout: PRS10 Connector Wire Color PRS10 function Pin 4 White TXD or PHOTO I/V OUT Pin 6 Green +24V Heater/Lamp Pin 7 Red RXD or EFC OUT Pin 9 Orange +24V Electronics Pin 10 Yellow Ground The center coaxial 10 MHz output is connected to the logic board via a white coaxial (RG-178 ?) cable. Pin 1 (PPS out) and Pin 5 (PPS in) are not connected. After I re-install the PRS10 in the TS2700, I'll add wires to log the RS-232 communication between the TS2700 and the PRS10. Thanks for sharing your investigation.
