Hello,

The referenced USB cable plugs into the input port of the controller. The referenced cable plugs into the PC. This is a closed loop. The “and” is missing. That “and” is the mount. The PC must see the mount. The controller sees the mount. The PC sees the controller only. The mount contains the RA and DEC motors. Motors are controlled by the hand controller in this NexStar model.

Something must happen for INDI to see the mount. One method is to use the ST4 port. The PC would see the mount through the ST4 port.

The Adafruit HAT can control RA and DEC motors which are accessible through a port or wiring. I use an AstroEQ to manage my external RA and DEC. To me, the Adafruit must have a custom cable to manage the mount through the ST4. The Adafruit and RPI4B replace the controller.

I am suggesting a picture of the assembly be taken to see how these three devices are being implemented. Add the picture here.
