I had been unsuccessful communicating with these units using the RS232 to RS422 cable hack that Stewart Cobb described in his original post (https://www.febo.com/pipermail/time-nuts/2014-October/087274.html). I was able to see, via a scope, the data coming out of the REF 1 unit, but it was never picked up on the PC.
I finally bought a USB to RS422/RS485 cable. That didn't work out of the box - I needed to use the supplied breakout board to remap the pins to a DB9-M connector as follows (Tx- to pin 8, Tx+ to pin 4, Rx- to pin 9, Rx+ to pin 5, Gnd to pin 7). All 4 wires were needed for this to work. Thanks to Bob Camp and Tom Van Baak for their help on this Anthony _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
