selection using the front panel pushbuttons, the remote control, or the
RS-232 serial interface.
Manual Selection
To manually select an HDMI source for a display, press the output
pushbutton that corresponds to the input port the display device is
connected to. Pressing the pushbutton will cycle the two attached HDMI

The remote control can change the Input source of any Output display,
power on/off individual Output displays, and power on/off all Output
displays simultaneously. Before using the remote control, the IR External
Receiver must first be plugged into the rear of the GHMS8422 and placed
where the IR signals can be received.
RS-232 Serial Interface
The GHMS8422’s built-in bi-directional RS-232 serial interface allows
system control through a high-end controller, PC, and/or home automation.
