RMT6-IR INSTALLATION

1. Remove battery cover from the back of the RMT6-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 RMT6-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will fl 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 RMT6-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

DIP SWITCH GUIDELINES

DIP SWITCH

EDID GUIDE

Extended display identifi cation 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 confi gured 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. Remove the hex screw heads from each side of the RS-232 port. 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.

EDID Mode 0 (Switch 1=OFF Switch2=OFF Switch5=ON)

-EDID is copied from the fi rst HDMI port
EDID Mode 1 (Switch 1=ON Switch2=OFF Switch5=ON)

-Same as Mode 0 and adds basic audio support
EDID Mode 2 (Switch 1=OFF Switch2=ON Switch5=ON)

-Same as Mode 0 and adds full audio support
EDID Mode 3 (Switch 1=ON Switch2=ON Switch5=OFF)

-EDID is generated based on the common video and audio features of all of the
connected devices

EDID Mode 4 (Switch 1=OFF Switch2=ON Switch5=OFF)

-Same as Mode 3 and adds basic audio support
EDID Mode 5 (Switch 1=ON Switch2=OFF Switch5=OFF)

-Same as Mode 3 and adds full audio support
EDID Mode 6 (Switch 1=OFF Switch2=OFF Switch5=OFF) DEFAULT

-EDID is generated based on the common video features of all of the connected
devices and the combined audio features of all of the connected devices

IR CODE CONFLICTS

How to Resolve IR Code Confl icts

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 (page

6) 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 confl icts with other home theater devices.

RS-232 INTERFACE

Additional control of the EDID modes and IR channel are possible using the RS-232
interface. For any of these modes to be successfully written to the EEPROM, all Dip
Switches must be in the OFF position.
