 ?? ? I have both of my units sitting on the bench. I found that I needed to connect them together to get the REF1 unit to come out of standby ? . ??

 ??I suspect that somebody will have to figure out what the 15 pin connector / jumper is doing. On previous RFTG units there was a way to re-wire the crossover interface to fake out the slave detect process. That would let you run a single GPS equipped box and have it behave correctly. Without the fake wires trick none of them played nice without the slave being present ? . ??
Reposting what I had posted over a week ago, in case you missed it ? .

Way back on Fri Jun 11 16:48:43 UTC 2010 I posted about using one of these units I had modified but at the time there wasn't a single person who was interested. I have been using the RFTG-u REF1 since then and it is a nice unit. The modifications I added (including a power supply -see photo) allows the lights to cycle through their normal sequence on warm-up and the second unit isn't needed at all ? . ??
