Hi,

Would anybody have the wiring diagram for a RJ45 PUC cable?

I'm having trouble sourcing a cable (seems to be a shortage) and was wondering if an existing cable with a 3.5mm pin could be repurposed with a RJ45 connector.

Thanks

Peter

Here's the page from the Beolink Handbook v1.9.  It shows the adaptors also, but doesn't actually map the connections across to confirm polarity (click to enlarge):

Further to this - I checked against the BV10 and BV11 service manuals.  For the IR PUC with 3.5mm plug the tip is the IR signal.  For the RJ45 version, pins 5 and 7 are the IR signal (pins 6 and 8 being ground) - here's the page in the BV11 manual:

Thanks Guy for the info.

I attempted to use an existing IR lead and convert to RJ45. That didn’t go well.

Have ordered the adapter.

No problem.  I assume that the 3.5mm PUC cables just weren't suited to crimping into an RJ45 plug.  To be honest I am generally averse to removing original plugs and connectors and prefer to make or buy adaptors, thus retaining the option to swap back.  In this situation I would probably take a spare RJ45 patch cable and cut one end off, then buy a 3.5mm socket and solder to the appropriate network cables.
