I have a case full of my cables all mixed and have confused my QHY5L-II guide cable with a few other RJ10 cables and can't remember which cable was the correct one.
Anyone here with the same camera can provide a picture of the correct RJ10 cable?
It should be a standard RJ11/RJ12 Cable with 6 pins, make sure there are six coloured cables in there and they are the same order at the other end and you are good to go.
