This driver uses the alignment procedures offered by Ekos that are based on the alignment subsystem of the indilib.
See the Align tab of Ekos. There is several documentation around.
This is the first step to see correct coordinates in your scope.
Remember that an alignment with ta least two stars can automatically establish if your mount is equatorial or altazimuth oriented.

I developed the serial connection for the driver on my CPC 1100 that has only serials, no USB.
If the AVX mount slew with manual commands from Ekos, this is really good. meaning that the AVX mount can be added to the supported list.

A question: which cable and port are you using? USB or RJ connector? If RJ, how many contacts has the connector?
