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.

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 underneath 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. 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.

-Same as Mode 3 and adds basic audio support

EDID Mode 5 (Switch 1=ON Switch2=OFF Switch5=OFF)
