Step 1
Use HDMI cables to connect the “HDMI In” ports on the
video display devices to the “HDMI Out” ports on the rear
of the GHMS8044.
Step 2
Use HDMI cables to connect the “HDMI Out” ports on the
source device(s) to the “HDMI In” ports on the rear of the
GHMS8044.
Step 3***
Plug the provided power adapter into an appropriate AC
power source; plug the power adapter cable into the
Power Jack on the GHMS8044. This completes the basic
installation of the 4x4 HDMI Matrix Switch. You may now
power on the display and source devices.
***Note: The matrix can take 15sec. to 60sec. to boot up
and capture EDID data.
To provide even more HDMI displays, additional GHMS8044 units can be cascaded from the parent
GHMS8044's HDMI Out ports, making it an excellent solution for digital signage systems. Simply use
additional Male-to-Male Type A HDMI cables to connect an HDMI Out port on the parent matrix to the
HDMI In port on the child matrix.
Recommended distances between devices in all cascade levels for transmitting a high resolution signal
are as follows:
Source device to GHMS8044 1.8m (5.9ft)
GHMS8044 to GHMS8044 15m (49ft)
GHMS8044 to display device 20m (65.6ft)
