If the mount receives equatorial coords, doesn't it convert it internally to Az/Alt and go to the target? Sorry not exactly familiar with how it works so how does it work now if you try to slew to a particular area in the sky as is?
No that is not as strait forward. The Skywatcher AZ/EQ 6 mounts designed to be mechanically configured in either Azimuthal (AZ) mode or Equatorial (EQ) mode. In equatorial mode, the RA axis is parallel to the Earth rotation axis, while in AZ mode, the RA axis is oriented to be parallel to the zenith axis.
With the hand control alone, at start up, I can inform the mount firmware that the mount is configured in AZ, which I can not do with the indi driver I have tried up to now.
Without knowing that the mount is in AZ configuration, the mount firmware will think it is in EQ mode and will give me a very bad pointing. Also, in AZ mode, I need tracking on both axis while in EQ mode, tracking on RA, with accurate initial calibration, shall be enough.
Of course, I can write down some formula to compensate for the difference but the mount firmware itself is already doing that, as long as it know that the mount is in either AZ or EQ mode. Thus I would rather prefer to use an indi driver that already give me the capability to work in AZ mode. Even if I still need to pass to the mount the RA/DEC coordinates, as long as I am able to inform the mount that it was installed in AZ mode, it should not be a problem. But, what is important is that the mount need to know how it as been setup.
I think I will open a new post on that subject. I may be get more indication.
I will close met issue regarding my problem of connection.
