I recently purchased one of the ASIAir wireless control units in an attempt to simplify the cable tangles on my telescope setup.
The ASIAir unit comes with a cable that lets you control the mount as well as cameras and other USB devices. However, the mount-control cable is a USB-A to DB9 - presumably for the NEQ6 type of mount. I have an EQ8 mount and want to use the device to control it, so I plan to add an adapter to the DB9 end that I can plug into the mount's RJ45 handset socket.
To avoid any chance of frying the mount's control circuitry, I need to ensure that the adapter has the correct pinouts at each end. After looking at the pinout diagrams for both the NEQ6 and EQ8 mounts, my question is: which DB9 pins should be connected to which RJ45 pins inside the adapter?
Thanks in advance for any authoritative advice.
