Thanks all for answering my question. 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

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.
