Hello!

I have a brand new iOptron CEM40EC and I am trying to get it to connect to one of my Stellarmates. I have tried all the cable and port combinations I can think of, including an RS232 to FTDI/USB, which works very well for my CEM120EC2. 

Has anyone out there successfully made this connection? Note that the newer CEM40EC port configurations are different from what iOptron shows in the manual. 

Thanks!
