The Linear 2x2 Switcher for HDMI routes high denition video in multiple resolutions
up to 1080p plus multichannel digital audio from either one of two sources to the two
displays. Two outputs gives you the choice of sending high denition audio and video
signalstotwodisplayssimultaneously.Adigitalaudiooutputportisavailableifyouneed
to direct the audio to anA/V receiver. The 2x2 Switcher for HDMI eliminates the need
todisconnectand reconnect sources to adisplayequippedwithoneinput. It works with
Blu-ray and HD-DVD players, TiVo systems and satellite set top boxes that connect to
an HDMI display. By using the IR remote, either source is accessible at all times.
How It Works
You simply connect all your sources to the switcher’s HDMI inputs. Then connect up
to two displays on the switcher’s HDMI outputs. Once the sources, the Switcher and
the display(s) are powered and connected, you simply select which source you want
to view using the IR remote.

Optionally, connect an external audio processor to the 2X2 Switcher for HDMI4. using a user supplied digital optical cable.
Plug the 5V DC power supply into the 2X2 Switcher for HDMI.5.
NOTE: *Display information (EDID) is sent from the display connected to HDMI
Output Port 1 to both of the sources connected to the 2X2 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 2X2 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 2X2 Switcher for HDMI is done using either
the supplied RMT2-IR remote or through the RS-232 serial control interface.
IR Remote Control
Pressing button one on the remote will select the HDMI source that is connected to
HDMI input port one. Pressing two on the remote will select the HDMI source that
is connected to HDMI input port two.

RMT2-IR INSTALLATION
1. Remove battery cover from the back of the RMT2-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 RMT2-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
repeated.
Note: The RMT2-IR ships with two batteries. One battery is required for operation,
the second battery is complimentary.
The optional IR extender allows you to
relocate your HDMI Switcher and still retain IR
control. Linear part# IR-EXTENDER

HowtoResolveIRCodeConicts
In the event that IR commands from other remote controls conict with the supplied RMT-2IR
remote control, changing the remote channel will alleviate this issue. The RMT-2IR remote control
and the 2X2 Switcher for HDMI have DIP SWITCHES for conguring 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-2IR is located underneath the battery cover. The 8 DIP SWITCH
bank for the 2X2 Switcher for HDMI is located inside of the unit. *DIP SWITCH 1 and 2 on the
RMT-2IR correspond to DIP SWITCH 3 and 4 on the 2X2 Switcher for HDMI.
NOTE: *DIP SWITCHES 1, 2, and 5 through 8 are not used on the 2X2 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 conicts present in your setup.
Disconnect power from unit before starting. Remove all cabling from unit.
To open the 2X2 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.
When DIP SWITCH adjustments are complete, carefully slide the unit back together. Being careful
not to over tighten the hex nuts, screw them back in above each HDMI connector and on the RS-
232 serial connector. Screw all of the screws from the sides and underside of the unit back into the
unit, again being careful not to over tighten the screws. Plug all cabling back into its proper location
on the unit. Reconnect power to the unit and test for IR conicts.
