I have three OTAs in my Obsy each with a motorised focuser but only one focuser control unit. I just swap the cable from the controller to the focuser motor on whichever OTA I'm using for imaging.

I'm now "upgrading" to run two cameras to double my image capturing whenever there's a gap in the clouds. So I need two focuser control units.

I've started a build of Robert Brown's DIY controller - just waiting for the bare PCB to be delivered from China.

I have a Lakeside focuser motor connected to one of the OTAs which has the standard Robofocus motor wiring on pins 1-5 of the DSub - but it also has a temperature sensor which looks to be connected to the pins 6-8.

Does anyone know what type of sensor is on the Lakeside units and what the pinout connections are across the pins 6-8?

If possible I thought I'd use this temperature sensor to do the focus compensation.
