INTRODUCTION  
Congratulations on your purchase of the 2x2 Switcher for HDMI 1.3. Your  
complete satisfaction is very important to us.

The Gefen 2x2 Switcher for HDMI 1.3  
Gefen’s 2x2 Switcher for HDMI 1.3 is equipped with two HDMI inputs and two  
HDMI outputs. Two inputs accommodate the simultaneous connection of up to  
two high denition video sources, such as satellite systems and Blu-Ray players.  
3D content can be displayed when connecting a 3DTV and 3D source. Two  
outputs send the high denition audio/video signals to up to two HDTV displays.  
Switching is done via the included IR remote.  
How It Works  
Connect all your sources to the 2x2 Switcher for HDMI 1.3 inputs. Then connect  
up to two displays on the output ports. Once the sources, the switcher and the  
displays are powered and connected, you then select which source you want to  
view using the IR remote.

OPERATION NOTES  
READ THESE NOTES BEFORE INSTALLING OR  
OPERATING THE 2X2 SWITCHER FOR HDMI 1.3  
By default, display information from the display connected to HDMI output port  
1 is sent back to the source. Therefore, the other display connected to the 2x2  
Switcher for HDMI 1.3 must be capable of accepting the timings, resolutions  
and audio formats of the display that is connected to HDMI output port 1. 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. There is a generic EDID  
programmed into the 2x2 Switcher for HDMI 1.3 that can be used instead. See  
page 11 for more details.

IR REMOTE CONFIGURATION  
Setting the IR Remote Channel on the RMT-8IR  
In the event that IR commands from other remote controls conict with the  
supplied IR Remote Control Unit, changing the remote IR channel will x this  
issue. The IR Remote Control Unit has a bank of DIP switches for setting the  
Remote IR channel.  
The DIP Switch bank is located underneath the battery cover.

Unit showing the exposed DIP Switch bank

The IR channel selected on the IR Remote Control unit must match the IR  
channel assigned to the 2x2 Switcher for HDMI 1.3. For example, if you set both  
DIP switches on the remote to the down position (IR channel 1), you must set the  
2x2 Switcher for HDMI 1.3 to use IR channel 1.  
Refer to page 10 on how to change the IR channel on the 2x2 Switcher for HDMI  
1.3.

Press and hold the EDID button.  
While holding the EDID button, press and release the Reset button. The  
input LED indicators, on the front panel, will represent the current IR channel  
for the Switcher: A blinking LED corresponds to DIP switch set to the ON  
position. An inactive LED corresponds to a DIP switch set to the OFF  
position.  
In the illustration above, the LED for Input 1 is blinking and the LED for Input  
2 is inactive. This indicates that the Switcher is set to IR channel 1.  
IMPORTANT: The selected IR channel must be the same as the IR channel  
set on the IR Remote Control Unit (see page 9). Refer to the table below for  
setting the IR channel.

EDID MANAGEMENT  
EDID Mode Selection  
1. EXTERNAL MODE:  
See page 10 for details on using the External EDID.  
2. INTERNAL MODE:  
To use this mode, press the EDID button on the rear panel until the front-  
panel LED marked “Int” turns bright green. This mode will use a preset  
EDID, from the factory, that is stored in the Gefen 2x2 Switcher for HDMI  
1.3. This pre-programmed standard EDID data structure is compatible with  
most A/V display devices. All resolutions and audio formats specied in  
this EDID will be passed to the source device. See the tables below for a  
complete listing of the resolutions and audio formats listed in this EDID.  
NOTE: All other HDMI devices/displays connected to the output ports MUST  
be compatible with at least one resolution/audio format specied in this  
EDID. It is recommended to set, on the source device, a common resolution  
and audio format shared by all attached devices/displays. This is to ensure a  
compatible signal is output to all connected devices/displays.

EDID MANAGEMENT  
External EDID Management  
The 2x2 Switcher for HDMI 1.3 features EDID Management. Before the source  
can send video or audio signals, the source device reads the EDID (Extended  
Display Identication Data) from the output devices connected to the Splitter.  
The EDID contains information about what type of A/V data that the source can  
send to each output device.  
The 2x2 Switcher for HDMI 1.3 distributes a single source to multiple output  
devices. This involves reading EDID data from more than one device.  
Management of the EDID data is important to maintain compatibility between all  
devices.  
The following EDID features are copied from Output 1:  
Supported Resolutions  
3D Support  
Audio Features  
EDID color features are built based on all attached displays, using the  
following rules:  
Deep Color will be enabled if one or more displays are connected to the  
Splitter supporting Deep Color.  
xvYCC (x.v.Color) is supported if all connected displays support it.  
Display Connections:  
If a display is not connected to Output 1, then no EDID changes are made,  
meaning that the previous EDID information will be used. This state will be  
in effect until a display is connected to Output 1 and the Splitter is power-  
cycled.  
EDID is built from Output 1 to the Input. The audio block will be copied  
from Output 1. EDID-copying is performed only when the Splitter is reset or  
power-cycled.
