CONNECTING THE 4X2 SWITCHER FOR HDMI
OPERATING THE 4X2 Switcher For HDMI
4
Connect the supplied cables from the HDTV HDMI sources (up to four) into the1. HDMI input ports of the 4X2 Switcher for HDMI.
Connect the displays (up to two) to the HDMI output ports* of the 4X2 Switcher2. for HDMI using user supplied cable(s).
Optionally, connect an external audio processor to the 4X2 Switcher For HDMI3. using a user supplied digital coaxial cable.
Plug the 5V DC power supply into the 4X2 Switcher For HDMI.4.
NOTE: *Display information (EDID) is sent from the display connected to HDMI
Output Port 1 to all of the sources connected to the 4X2 Switcher for HDMI. If
there is no display connected to HDMI output port 1, the EDID from the display
connected to HDMI output port 2 will be used. The source will output resolutions
and timings according the EDID that is being fed by the 4X2 Switcher for HDMI.
Therefore, all of the connected displays must be capable of accepting the timings
and resolution output by the source. It is recommended that the display with the
lowest native resolution be connected to HDMI output port 1. This is to ensure that
a compatible video signal will be able to be displayed on all connected monitors.
Switching between the inputs on the 4X2 Switcher For HDMI is done using either
the supplied RMT4-IR remote or through the RS-232 serial control interface.

to HDMI input port one. Pressing two on the remote will select the HDMI source
that is connected to HDMI input port two. Pressing button three on the remote will
select the HDMI source that is connected to HDMI input port three. Pressing four

RMT4-IR INSTALLATION
1. Remove battery cover from the back of the RMT4-IR remote.
2. Verify that dip switches 1 & 2 are in the down (OFF) position. (See page 6)
3. Insert the battery, hold the battery so that you can see the positive side facing up.
The side that is not marked must be facing down.
4. Test the RMT4-IR remote by pressing ONLY one button at a time. The indicator
light on the remote will ash once each time you press a button.
WARNING: Do not press multiple buttons simultaneously and do NOT press buttons
rapidly. These actions will cause the remote to reset and steps 1-4 will have to be

HowtoResolveIRCodeConicts
In the event that IR commands from other remote controls conict with the supplied
RMT-4IR remote control, changing the remote channel will alleviate this issue. The
RMT-4IR remote control and the 4X2 Switcher for HDMI have DIP SWITCHES for
conguring the remote channel that both units use to communicate. These settings
must match each other for proper operation. The 2 DIP SWITCH bank on the RMT-
4IR is located underneath the battery cover. The 8 DIP SWITCH bank for the 4X2
Switcher for HDMI is located inside of the unit. *DIP SWITCH 1 and 2 on the RMT-
4IR correspond to DIP SWITCH 3 and 4 on the 4X2 Switcher for HDMI.
NOTE: *DIP SWITCHES 1, 2, and 5 through 8 are not used on the 4X2 Switcher for
HDMI.
Because the procedure for changing channels requires the main unit to be
disassembled, this procedure should only be done if there are IR conicts present in
your setup.
To open the 4X2 Switcher for HDMI Unit, remove all screws from the sides and
underside of the unit. Remove the hex nuts above each HDMI connector and on the
RS-232 serial connector. Slide the unit apart carefully to expose the internal PCB and
the 8 DIP SWITCH bank.
