I have the SL30 hooked up, both TX and RX, on a serial port 2. I'm getting a needle indicating a bearing to the station and VOR freq and ID on the Skyview, but I'm not getting a CDI nor can I change the course. When I select OBS on the SL30, I get "FLAGGED" on the SL30. I suspect a setting in the SL30 set-up parameters. What are the settings for the SL30 to fully talk to the Skyview. I have "SERIAL" on the SL30 setup menu.....................What else?
