What is the PC port on my CGE mount for?

If you have hand control firmware version 4.13 or higher, the MC firmware can be upgraded via the port on the bottom of the hand control. For this you need the NexStar RS-232 cable (part number 93920).
If your computer lacks a serial port, you’ll also need a USB to RS-232 converter cable for either method (Celestron part number 18775).
