Connecting the ASIAIR series to the Explore Scientific PMC8 fitted mounts like the EXOS2 and the Losmandy G11's sold by ES can be problematic unless you have the right cable and configuration settings on cable and ASIAIR!
This was a new one on me and its to do with the way the PMC8 monitors the RS232 cable for connected equipment and it need a specific cable to get it working!
This is a regular support question and I got Tyler to show us the right cable to buy, how to program it so that it recognises the ASIAIR and what configurations to choose on the AA to make a successful connection.
without this cable its going to be a lesson in frustration
