I sent you my posting earlier today, so hopefully you saw it. The Lucent unit seems liberal in its interpretation of the pinouts, but once you've deciphered it and got the +ve and -ve pins connected, it works reliably.

I looked through old posting but obviously didn't stumble upon Anthony's posting otherwise I would have had my answer. I made up a short cable to connect the Startech ICUSB422 to the KS-24361 J8 Diagnostic port and I can now connect. This is the final pinout: Startech KS-24361 ICUSB422 J8 - Diagnostic ========================================= 1 TXD- --------------> RXD- 8 2 TXD+ --------------> RXD+ 4 3 RXD+ <-------------- TXD+ 5 4 RXD- <-------------- TXD- 9 5 GND --------------- GND 7 6 NC 7 NC 8 NC 9 NC Seems RS-422 is a standard but pinouts vary. Live and learn. cheers, Graham ve3gtc On 2014-12-01 21:10, Bob Camp wrote: > Hi > > If you dig back a month or so, there is a post with all the pinouts on all > the connectors. > > 4 RX+ > 8 RX- > > 5 TX+ > 6 TX- > > 3 and 7 ground > > It ??s serial so TX on one goes to RX on the other. + goes to + and - to -. > The pins are numbered on the connector in *very* small print. > > Bob > > > _______________________________________________ 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. _______________________________________________ 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.
