Our Commitment
Gefen will always offer the finest quality product at the best possible price. Included in

The ex•tend•it 2x4 HDMI Switcher/Splitter allows two HDTV HDMI devices to be dis-
tributed easily in to four HDTV HDMI compatible monitors or projectors. Simply connect
your HDTV displays to the DA’s display outputs. The 2x4 HDMI Switcher/Splitter can

How It Works

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

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.
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 flash 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 have
IR control of the HDMI Switcher
IR CODE CONFLICTS
How to Resolve IR Code Conflicts
There are matching pairs of dip switches underneath the Switcher unit and under the
remote battery cover. Switch 1 & 2 on the Remote and Switch 3 & 4 inside the unit are the
matching switches. These switches need to be matched for the remote to
communicate with the switcher. There are 4 possible sets of IR codes and at least one of
these sets should be able to resolve any IR conflicts with other home theater devices.

DIP SWITCH GUIDELINES
Extended display identification data (EDID) is a data structure provided by a display to
describe its capabilities to any source that asks for it. The EDID includes manufacturer
name, product type, timings supported by the display, display size, luminance data, (for
digital displays only) pixel mapping data, supported audio channels and formats. This
information is used by the source to cater its output to resolutions and audio formats
that are supported by the display.
Additional EDID modes are available and configured using a combination of dip
switches 1, 2, and 5. Please refer below for the different EDID modes.
To access the Dip Switches, remove all screws from the bottom and sides of the Gefen
unit. Carefully slide the unit apart. The 8 Bank of Dip Switches are located on the main
PCB. Once adjustments are complete, slide the unit back together and replace all
removed screws.
