Did you power cycle both units as part of connecting them together at J5 to J5? And can you remind me whether you are using the supplied interface cable, or are you using something else? After warmup, the ON light is on for the REF-0 unit and the STBY light is on for the REF-1 unit. While running, there is no output from J8 on the unit marked STBY. J8 works on the unit marked ON. There is a timestamp coming from J6, and I think a 1PPS signal on some pin or other.

I'm still having no luck with mine. When I power on, the LEDs cycle, the Fault light is on and the No GPS and Standby lights flash. When I connect my GPS antenna, the No GPS light stops flashing and stays on. After several minutes only the Standby light is on.
When I connect both the Ref1 and Ref0 together with the interface cable, the Fault lights on both units are illuminated.
Do you see the same? I don't know what to infer from the Fault light since there is no supplemental data to work from.
