To disable the function: press the output2 selection button and the key lock button at the same time for
about 3 seconds. After all the output1 LEDS and the output2 LEDS flash twice, the function is disabled.
The sequence of “IR1, IR2, IR3, IR4” one-to-one correspond with “HDMI INPUTS1 through 4”. When an
output chooses certain input, the call-back IR signal of RJ45 on this output will choose the correspond-
ing “IR” port to send the signal out.
For example, OUTPUT1 chooses INPUT3, and then the call-back IR signal of RJ45 on OUTPUT1 will
choose “IR 3” to send the signal out.
Note: The switcher can only accept and route IR signal which doesn’t exceed 38 KHz. In other words, if you are
trying to send IR signal from the remote location though out HDMI receiver and the IR signal is higher than 38
KHz, the IR signal will not pass though.
EDID SETTINGS
(PLEASE READ, IT IS VERY IMPORTANT)
When any of our HDMI/DVI distribution amplifiers are powered on, they will automatically go through
an Identification cycle, which means that each output will send an EDID call back request to each one
of the display. Once that done, the distribution amplifier will identify the data received and choose the
most appropriate EDID setting. The EDID setting chosen will be compatible with all the displays.
The reason why we manage EDID the way we do is because we want to make sure that user will al-
ways get signal.
If customer does want to send higher resolution to all the displays which are 1080p and lower resolu-
tion to the 720p display, we do offer a up/down scaler box which would be able to scale 1080p down to
whatever the TV’s native resolution is.
When it comes to our larger matrix switchers, starting at 4x8, we allow users to choose the EDID. User
can even choose 1080p and 7.1 Channel Audio, even though some displays may not be compatible. In
this case no audio or video will appear on the displays that can’t
Support it; however since it is a matrix switch some inputs not always have to be selected and therefore
the EDID settings are the way they are.
The functionality of the switch will depend on how you select the DIP Switches below. Please read the
instruc¬tions and explanations below to understand the purpose of different configurations. There are
four DIP switches on the back of the 4x4 matrix switcher. Below you will find the definition of each one
of the dip switches.
