feet away from the work area. The ex•tend•it line offers solutions for noise, space and
security concerns, data center control, information distribution, conference room presen-
tation, and school and corporate training environments.

crowded with double displays, keyboards and mouse devices. It saves time - there’s no
need to move from one monitor to another to access different computers.And, it saves
money - there’s no need to purchase additional displays, mouse devices, keyboards etc.

Connecting and Operating the 4x1 DVI DL Switcher
How to Connect the 4x1 DVI DL Switcher to your devices
1- Connect the supplied cables from your first computer into the DVI In 1, USB In 1,
and Audio In 1 connection in the back of the DVI Switcher.
2- Repeat step one for up to four computers on inputs 2-4.
3- Connect the monitor to the DVI Out connection.
4- Connect your USB devices (e.g. keyboard, mouse) into the USB Out.
5- Connect your speakers to the Audio Out.
6- Plug the 5VDC power supply into the 4x1 DVI DL Switcher.
How to Operate the 4x1 DVI DL Switcher
1- Use the RMT4-IR remote control port to remotely switch between sources.
2- Use the RS-232 interface with a compliant device to switch between sources.
Operation Notes
When turning on or rebooting your computers, the 4x1 DVI DL Switcher must be
selected to the computer that is booting until the computer completes the boot
cycle. This step can be eliminated using the Gefen DVI Detective (w/ dual link
cable).
If you loose your picture when you switch between sources you will need a DVI
Detective.
The 4x1 DVI DL Switcher is Dual Link ONLY. To switch between Dual Link and
Single Link sources, a Single Link cable (sold separately) must be used for each
Single Link source connected to the switcher.

RMT4-IR Installation

1. Remove battery cover from the back of the RMT4-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 RMT4-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 RMT4-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.
DIP SWITCH GUIDE
if you are experiencing Infrared interference, you can change the IR code on the Re-
mote and the 4x1 DVI DL Switcher itself.
To change the IR code on the RMT4-IR, simply remove the battery cover and find the 2
dip switches just above the batteries. These switches correspond to a set of switches
on the 4x1 DVI DL Switcher.
To change the IR code on the 4x1 DVI DL Switcher, look under the unit and find a silver
sticker. Beneath this sticker is a group of 4 dip switches. The first 2 switches (labelled 1
and 2) correspond to the 2 switches found on the RMT4-IR remote control.
The following are the 4 Infrared channels possible for both the RMT4-IR and the
4x1 DVI DL Switcher. The dip switches on both the remote and the switcher itself must
match in order to be operational.
