Hardware Installation

Make sure that the power to any device that you connect to have
been turned off and all devices you will be installing is properly
grounded.
To install the switch, refer to the installation diagram as you perform
the following steps:
1. If you are using the serial control function, use an appropriate
RS-232 serial cable to connect the computer or serial controller to
the GHMS8422's female RS-232 port.
2. Use a grounding wire to ground the unit by connecting one end of
the wire to the grounding terminal and the other end of the wire to a
suitable ground.
Note: Do not omit this step. Proper grounding helps to prevent
damage to the unit from surges or static electricity.
3. Use HDMI cables to connect the video display devices to the HDMI
output ports on the rear of the GHMS8422.
4. Use HDMI cables to connect the video source devices to the HDMI
input ports on the rear of the GHMS8422.
5. Connect the IR Receiver to the External IR Receiver Input Port (if
you will be using this feature).
6. Plug the provided power adapter into an appropriate AC power
source and plug the power adapter cable into the Power Jack on
the GHMS8422.
This completes the basic installation of the 2x2 4K HDMI Matrix
Switch. You may now power on the display and source devices.
