Do not plug the External Power cable into the USB
port. This will destroy your Hiper-AG receiver.
WARNING
Use the attached port cover to seal the USB port. This will prevent any
accidental plugging of the external power into the USB port.
Communication with the X20 console is achieved by plugging the
Communication (Comms) cable (Figure 5-1) into either the A or D
Ports. The 9 pin (computer) plug on the other end of this cable plugs
into the COM1 Port on the back of the X20 console (Figure 5-2 on
page 5-2).
