Moray can you Mix n match or is it one or tuther..?

Mix and match.

There are 8 encoder channels (actually 16 differential inputs on the Kanalog - they're not solely for encoder inputs), which at KFlop level means 16 inputs, but those 16 inputs are actually general purpose IOs which also provide the Step/Dir outputs.
4 of the encoder channels go through a separate RJ45 (Ethernet style connector) cable to the Kanalog, with the other 4 being in amongst the main 26pin ribbon cable with all the other signals. If you only need 4 encoders, you can simply make up your own cable to take 4 sets of Step/Dir signals from the RJ45 connector on the KFlop. Otherwise you have to start splitting cables depending on how many encoders and Step/Dir signals you need.
