Hardware Installation
To install the switch, refer to the installation diagram as you perform the following steps:
1. Use an HDMI cable to connect the video display device to the HDMI output port on the rear of the GHSW8441/
GHSW8481.
2. Use HDMI cables to connect the video source devices to the HDMI input ports on the rear of the GHSW8441/
GHSW8481.
• If you are using the serial control function, use an appropriate RS-232 serial cable to connect the computer or
serial controller to the GHSW8441/GHSW8481’s female RS-232 port.
• 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. Plug the provided power adapter into an appropriate AC power source and plug the power adapter cable into the
power jack on the GHSW8441/GHSW8481.
4. Connect an IR extender (not supplied) to the external IR receiver input port (if you will be using this feature,
otherwise you can skip this step). This completes the basic installation of the 4/8 port 4K HDMI Switch. You may
now power on the display and source devices.
5. In order to use the RS-232 serial interface to attach to a controller (such as a PC) and the GHSW8441/
GHSW8481, use a serial modem cable. The end connecting to the GHSW8441/GHSW8481 should have a 9-pin
male connector (DB-9).
