Lucent KS-24361 RS-422 interface pinout
I got my pair of REF-0 and REF-1 to lock, REF-1 is now in STBY and the
REF-0 is on. Thanks to Bob suggesting I wiggle and/or re seat the
interface cable.
However, I have not been able to "peek" inside using the DIAG port.
Rather than try the hack suggested by Stu I bought a USB to RS-422
interface cable, a Startech ICUSB422. It has a DB-9P which plugs
directly into the DIAG connector BUT on comparing it's pinout to the
"hack cable" suggested by Stu, it seems that they really don't line up
correctly.
This is Stu's suggested "hack cable" from his very informative earlier post
RFTG PC
DE-9P DE-9S
7 <---GND---> 5
8 <--------- 3 TXD
9 ---------> 2 RXD
The ICUSB422 pinout is as follows (arrows point in direction of data flow)
ICUSB J8 - Diagnostic
1 TXD- --------> 8 (based on Stu's diagram and description)
2 TXD+ --------> ??
3 RXD+ <-------- ??
4 RXD- <-------- 9 (based on Stu's diagram and description)
5 GND --------- 7 (based on Stu's diagram and description)
6 NC
7 NC
8 NC
9 NC
But what pins to TXD+ and RXD+ connect to? After much searching and
looking at a bewildering number of variations of pinouts, I am still
confused on where these two go. A Wild Ass Guess (WAG) is that 2 TXD+
--> 4 and 4 RXD- <-- 5 but I am really uncertain and that is just based
on one of the pinouts I found in my searchs.
I thought I would be lucky and would just be able to plug and play with
the ICUSB422 directly to the J8 Diagnostic port but it isn't so; I will
need to make up an additional adapter to get the right pins going to the
right pins.
I am hoping someone on the list knows for certain. Failing that I will
have to poke at it with a scope or DVM tomorrow and to see if I can make
sense of it.

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.

Hi Graham,
There was a post, I think by Anthony, that discussed the USB adaptors. But your pinout looks different than the adapter I got. You have pin 1 listed as TX (-) whereas on mine pin 1 is TX (+). Likewise, you list pin 2 as TX(+) where mine is TX (-). In any case, here is the wiring I used on J8
4 TX (+)5 RX (+)8 TX (-)9 RX(-)7 Gnd
At first, I thought the USB adapter I got was bad. The problem turned out to be that it doesn't play well with a USB extension cable.

I haven't had any luck with my 422 adapter so I'm still using the - lines.

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.

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.
