HOW TO CONNECT THE 4x1 DVIKVM SWITCHER

Connect your computers DVI, USB, and audio to the 4x1 DVIKVM Switcher inputs

using the supplied cables.

Connect your DVI display to the DVI output of the 4x1 DVIKVM Switcher.

Connect your USB and audio devices to the USB and audio outputs.

Connect the RMT-4 remote control (if applicable).

Connect the External IR Extender to the RJ-45 port (if applicable).

Plug the 5VDC power supply into the 4x1 DVIKVM Switcher.

Your computers must be turned on one at a time and the switcher must be selected

to the computer that is booting up.After one computer completes the startup process,

you can boot up the second computer and repeat the process with the remaining

computers.

RMT-4IR

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.

How to Operate the IR Extender Eye (optional)

Plug in the IR extender eye to the extender port on the back of the switcher. As soon as

the IR extender eye is plugged in you can extend your IR signal. The IR extender eye

does not come included in the package.

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.

IR CODES

In the event of IR conﬂicts, please do the following:

1. Remove the battery cover from the back of the RMT4-IR remote.

2. Locate the Dip Switches above the batteries.

3. Switch the Dip Switches on the RMT4-IR to any of the combinations pictured below.

4. Dip Switches 1 and 2 in the RMT4-IR correspond with Dip Switches 3 and 4 on the

bottom of the 4x1 DVI Switch respectively. Switch the switches on the bottom of the

4x1 DVI Switch to match the dip switches on the RMT4-IR. The 4x1 DVI Switcher is

now set to a new IR Code.
