Have you tried the following?
Select "iOptron CEM40(EC)/GEM45(EC)" in ASIAIR.
In SkySafari, use Scope Type "iOptron CEM/iEQ Pro/AZ Mount Pro."
For SkySafari Communication settings, use Port 4030 as the ASIAIR mount proxy port for the iOptron mounts.
If ASIAIR is set up as a wireless HotSpot, and your iPad's networking is connected to the ASIAIR access point, use 10.0.0.1 as the IP Address in SkySafari.
If your ASIAIR is connected to your home network, either with WiFI Station Mode, or with Wired Ethernet, check ASIAIR or your router for the IP Address that has been assigned to ASIAIR by your home router, for example, something like 192.168.0.234.
I don't use an iOptron mount, but the above works with my mount simulator, set to simulate the CEM40/GEM45.
