Yes, unfortunately that is a very unhappy choice of Hitecastro to provide only a cigarette adapter plug power supply.
I had to cut mine and adapt so I have both possibilities.
I emailed David again to request communication protocol. On initial testing, it seems the focuser connects just fine, but I don't have any DC motors around to test it with the actual unit, but it's responding fine. I asked David to send me the communication protocol and waiting for response.
Have you had any response from David regarding the communication protocol? Meanwhile I tried to use Kstars for Windows but don't seem to be able to install my gear locally. Only remote installation is possible. ("Local" is greyed out).
Do I have to install any drivers. The ascom drivers for my gear I have but do I need indilibrary drivers and how do I install those? Thx.
I literally spent the whole day writing a completely new driver for this, but I still can't get any response from the controller. I emailed David to ask for more info and we'll see, but the driver is ready whenever this bit of communication issue is resolved.
