Finally got a chance to try this. The first time I connected the solar guider it wouldn't show up as any port and was throwing an error. Unplugged and replugged back in and it came up as its own separate COM port from the CP4. Not sure what was going on but it seems to be working now.
Greatly appreciate your time and help!
Glad to hear it's working. Windows is picky about USB drivers. The fundamental rule of thumb is, install the driver software BEFORE plugging in the equipment. Maybe if finally figured out what driver to us for your solar guider.
