HDTV displays. All output displays will have mirrored images.

The ex•tend•it line offers solutions for Home Theater, A/V installation, data center,

information distribution, conference room presentation, school and corporate training

Our Commitment

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

that price is a lifetime support from a team of outstanding engineers.

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

also be placed at the end of a long HDMI cable to regenerate the HDMI signal.

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

remote.

CONNECTING AND OPERATING 2x4 HDMI SWITCHER/SPLITTER

How to Connect the 2x4 HDMI Switcher/Splitter to your devices

1 Connect the supplied cables from the HDTV HDMI sources into the 2x4 HDMI Switcher/

Splitter inputs.

2Connect the cables from your displays (monitor or projector) into the HDMI outs of the

2x4 HDMI Switcher/Splitter.

3 Plug the 5VDC power supply into the 2x4 HDMI Switcher/Splitter.

How to Control the 2x4 HDMI Switcher/Splitter

Use the RMT2-IR remote control to toggle between sources.

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.
