I have a problem with this thing. Trying to mend it and wondered if anyone will please buzz out the round plug that goes from the multiplexer to the RS232/RS485 converter.

Attached is a pic of my cable, it seems to be slightly different to most as I have a short cable with a 15 pin D type on the end, I have also two cables that will attach to that, one with the RS232/RS485 converter in and one without, just a 9 pin D type on the other end. It seems that all the ones I have seen on eBay have only one cable, the RS232/RS485 cable with a 9 pin D type on one end and the round multiplexer plug on the other.

What I need is for some kind person to look at the pictures and buzz out there RS232/RS485 round plug and tell me if there are shorts in the cable as shown on my picture. I have tried to find a schematic for this cable and can't find one and I do not know anyone with one of these things.

If you're near Burnley and you have one and don't mind me poking it then let me know and I will be much appreciative.

I have access to several Star Diagnosis. I'll check as soon as possible and let you know.

I actually found the schematics for it so here it is for the next guy that is looking.
