The Gefen 2x4 Switcher for HDMI 1.3
Gefen’s 2x4 Switcher for HDMI 1.3 is equipped with two HDMI™ inputs and
four HDMI outputs. Two inputs accommodate the simultaneous connection of
up to two high definition video sources, such as satellite systems and HD DVD
players. Four outputs send the high definition audio/video signals to up to four
high definition displays. Switching is done via the IR remote that is provided with
the unit.
How It Works
You simply connect all your sources to the Switcher’s inputs. Then connect up
to four displays on the output ports. 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.
Note:
All displays that cannot show the same video resolution(s) as the Primary Display
connected to Output #1 may fail to show a picture. Secondary displays follow the
Primary by sharing the resolution and capability information (EDID) obtained from
the Primary Display.

the features for HDMI1.3 will be enabled. The 2x4 Switcher for HDMI 1.3
features an EDID selection that will allow the user to choose an external
EDID from an attached display or an built-in internal EDID. Please see page

How to Connect the 2x4 Switcher for HDMI 1.3
1. Connect up to two HDMI source devices to the 2x4 Switcher for HDMI 1.3
using the supplied HDMI cables.
2. Connect up to four HDMI capable devices to the 2x4 Switcher for HDMI 1.3
using the supplied HDMI cables.
NOTE: The display connected to the port labeled OUT 1 will have its EDID
used when the external EDID mode is active. If there are displays with different
resolutions in the setup it is recommended that the display with the lowest
resolution be placed on the HDMI port labeled OUT 1. This way, all of the
displays should be able to display an image when the external EDID mode is
active.

EDID Modes and Reset Buttons
The EDID source is selectable between the display connected to the HDMI
output port labeled OUT 1 or the built-in internal EDID. These 2 modes are
selectable by toggling the EDID button located on the back panel. To switch
modes, follow the instructions below.
1. Note the current EDID mode by viewing the front panel’s LED array. If the
INT LED is active the internal EDID mode is in use. If the EXT LED is active
the external EDID mode is in use.
2. If the currently selected EDID mode is not the desired EDID mode, press the
EDID button on the rear panel once. The active LED will now switch and the
new EDID mode will become active once the unit is reset.
3. Press the reset button to cycle power and initiate the newly selected EDID
mode.

IR CHANNEL CONFIGURATION
Why would I need to change the remote channel?
In some instances, the 2x4 Switcher for HDMI 1.3 may use IR codes that conflict with
other IR remote control devices. The unit may switch inputs when another brand IR
remote control is used or the RMT-2IR may cause other brand IR controlled devices
to behave unexpectedly.
I am experiencing the issues listed above. What do I do?
In these cases it is recommended to change the IR channel that the RMT-2IR
remote control and the 2x4 Switcher for HDMI 1.3 use. The IR channel is configured
independently on the RMT-2IR remote control and the 2x4 Switcher for HDMI 1.3 but
the channel selection must match on both units for proper operation.
How Do I change the Remote Channel?
There are service DIP switches on the RMT-2IR remote control for channel
configuration. The 2x4 Switcher for HDMI 1.3 uses a combination of buttons on
the rear panel to configure the IR channel. There are 4 channels available for use.
Please use the diagram below and information on the next page to locate and
change the IR channel to one that is not the default. Remember that the IR channel
must match on both the unit and remote control for successful operation.

IR CHANNEL CONFIGURATION
LED Indicators
The 2x4 Switcher for HDMI 1.3 uses inactive LED and blinking LED combinations to
indicate to the user which channel is currently active. The Currently Selected Input
LED Indicators (Item 6 on page 4 and 5) are the two LEDs used to indicate the IR
channel. These LED’s will directly correspond to DIP switches 1 and 2 on the RMT-
2IR remote control.
LED Input Indicator 1 corresponds to DIP switch 1 on the RMT-2IR remote control.
LED Input Indicator 2 corresponds to DIP switch 2 on the RMT-2IR remote control.
An inactive LED will correspond to a DIP switch set to OFF.
Ablinking LED will correspond to a DIP switch set to ON.
For example: IR Channel 2 would be indicated by the following:
RMT-2IR: DIP switch 1 - ON
DIP Switch 2 - OFF
Main Unit: LED Input Indicator 1 - Blinking
LED Input Indicator 2 - Off
Changing IR Channels on the 2x4 Switcher for HDMI 1.3.
The 2x4 Switcher for HDMI 1.3 will use the EDID and Reset buttons, located on
the rear panel, for IR channel configuration. Use the steps below to change the IR
channel. Please ensure that the IR channel matches on both the RMT-2IR remote
control and the 2x4 Switcher for HDMI 1.3.
1. Press and hold down the EDID button.
2. While holding the EDID button, press the Reset button once.
3. The LED indicators for the current IR channel will be active.
4. While holding the EDID button, press the Reset button once to cycle to the next
IR channel. The LED indicators will indicate the IR channel change.
5. Repeat step 4 until the desired channel is reached.
Note: The IR channel will cycle from Channel 1 through Channel 4 and then cycle
