I have struggled with this before also. We ended up with a CAT5e cable with an RJ45 on the processor end and solder/crimping the Tx/Rx/C conductors to a 3.5mm TRS connector into the Niles ZR6. I forgot the pinout, you will need to look at the XP6 and ZR6 documents.
We did similar on a ZR-6...We may have used a URC remote cable..been awhile
has been a couple of years now but no issues on any we have done
