celestron Aux driver: Connects but doesn't work

mount
Advanced-VX

I created an interface for this site and tried to connect.

It is connected and the mount position is displayed at the north pole of the home position, but it does not work even if GOTO is performed.

The mount position does not change even if you operate it with a mount controller.

We will send you a log of the operation, so please check it.

There was a wiring mistake in one place, and when I fixed it, it worked.

However, the coordinates of the driver seem to be only the coordinates of the fork-type equatorial mount. (I found the cause using SkyPotal)

German equatorial mounts, such as the Advanced-VX equatorial mount, are currently unavailable due to their different coordinates than the folk equatorial mount. ....

Please have the coordinates of the German equatorial mount ready.

On Cloudy Nights, the handle name mlord has published a number of homebrew interfaces for Celestron mounts.

The interface I made is one of them, but I think the interface that connects to UART is the easiest to make.

If you use this circuit, you can connect the Celestron mount directly to the USB of the PC from the AUX terminal or HC terminal like EQMOD.(However, the German Equatorial Mount works because the driver does not have the correct coordinates, but it moves to a considerably different position with GOTO.)
