Setup

Note: All Cat5e/6 cables must be terminated to 568B standards. 

Unsheilded (or properly terminated sheilded cable), solid core Cat5e,

 

Cat6, Cat6e, Cat7 or Cat7e cable can be used. Str

anded core is not 

suggested as it can reduce signal transfer. Recommended to use a 

continuous length of cable terminated at the matrix and receiver ends.

With the matrix power switch in the OFF position, connect an HDMI High 

Speed cable from the HDMI Output of the most commonly used audio/

video source to the HDMI Input 1 located on the rear of the matrix. 

Similarly

, connect the remaining source devices to the HDMI Input Ports 

on the matrix.

Tips: Use the shortest length HDMI cables possible in each point 

in the installation. Use only High Quality and High Speed HDMI 

cables.

If desired, run a LAN cable from your network or router into the port 

labeled LAN IN on the rear of the matrix.

Next, connect a Cat5e/6 cable to the HDBase

T Out 1 port on the rear of

 

the matrix. Connect the other end of the Cat5e/6 cable to the HDBaseT 

IN port on the rear of the HDBaseT receiver positioned near the TV. Run 

a short, High Speed HDMI cable from the HDMI Out port on the receiv

er 

to the HDMI In port on the TV.  If desired, two Ethernet ports are 

provided on the rear of the receiver for connection to Internet enabled 

TV and/or computer. Plug a provided power adapter into an AC outlet 

and the other end into the HDBaseT receiver. Using the same steps, 

connect the remaining audio/video sources to the matrix.

The matrix has internal memory that stores the system 

information for faster switching. Please follow the steps in the 

order listed:

 T

urn ON the displays and ensure they are awake (not in 

standby mode). Check the displa

ys INPUT setting to ensure the correct 

HDMI port is active. 

T

urn on the source devices and ensure they are awake (not in standby

 

mode). Connect the power adapter to the matrix. Plug the power 

adapter into a surge protected AC power outlet. Turn the matrix power 

switch to the ON position.

The matrix has a low power draw and is intended to be left on. If 

the matrix is turned off, start up the system as noted above. If new 

hardw

are is added, please perform a RESET

.

To

 RESET the matrix, turn off the display and source devices. 

Power off 

the matrix and unplug the power adapter from the rear of the matrix. 

Wait 20 minutes for the memory of the system configuration inside of 

the matrix to be deleted. 

Fo

llow the setup instructions above to correctly 

initiate the setup.
