Control
USB connections
Connect a host computer to the USB mini-B port on the receiver (see
Receiver connections for display or device control
The serial, IR, digital I/O, LAN, and CEC ports can all be used for device control. All of these ports must be configured using
Global Configurator
Serial
For serial control using RS-232, connect the serial control port
of the AV device to the COM port (see
3) of the HCR 102 receiver as shown below.
