Connecting a PC to the Maintenance Port

To program your user-defined satellite(s), you first need to connect a

PC with Windows HyperTerminal installed.

TIP: If you are a KVH-authorized technician, you can use the KVH Flash

Update Wizard instead of HyperTerminal. Enter commands in the wizard’s

“Antenna Comms” window. You do not need to flash the antenna to enter commands.

1. Set the switchplate’s power switch to the Off (down) position.
