Telescope and mount: NexStar 4se
USB2Serial cable: ATEN UC-232A
OS: OSX 10.9.2 (Mavericks)

Scope is configured as Celestron NexStar 4 GT.
Pressing the connect button results in the "Configure" button being greyed out. All other buttons remain greyed out, and the position displays show "N/A".
Using the same configuration on SN6 on the same Mac works as expected.
