Why are there two COM ports on the servo drive electronics box?
You can use DigitalSky Voice™ software (included with your mount), in conjunction with Software Bisques TheSky™. You will need two available serial ports on your computer since both programs must obtain positional data from mount continuously. Our computer drive system was designed to input/output RA and Dec numbers (same protocol as the Meade LX200, LX650 and LX750 mounts). Other programs written with this protocol should also work.
