INTRODUCTION Congratulations on your purchase of the 4x4 VGA Matrix. Your complete satisfaction is very important to us. Gefen Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies.
OPERATION NOTES READ THESE NOTES BEFORE INSTALLING OR OPERATING THE 4X4 VGA MATRIX • The 4x4 VGA Matrix does not transmit display information (EDID) to the source. Standard VESA resolutions should be output by most computers without the need of an EDID. If using a non-VESA standard resolution or if EDID is needed, an EDID storage and relay device is necessary. Gefen recommends the use of a DVI Detective (part# EXT-DVI-EDIDN) with two VGA to DVI adapters.
FEATURES Features • Switches easily between any four VGA/Analog Audio sources • Sends up to four VGA inputs with Analog Audio to any four displays with Analog Audio • Supports high-definition VGA up to 1920 x 1200 resolution at 60 Hz • LED lights on the front panel show selected VGA routes • RS-232 Control • Includes discrete IR remote control Package Includes (1) Gefen 4x4 VGA Matrix (4) 6 ft. VGA Cables (M - F) (4) 6 ft. 3.

PANEL DESCRIPTIONS 1 Power LED This LED indicator glows RED when power is connected properly and sufficient power is being received by the Matrix. 2-5 Selected Input LED Indicators For Outputs 1-4 Each of the four output ports has an associated bank of 4 LED indicators that shows which input source 1-4 is active for that output. The currently selected input will be indicated by an active LED.
CONNECTING AND OPERATING THE 4X4 VGA MATRIX How to Connect the 4x4 VGA Matrix 1. Connect up to 4 VGA video sources to the 4x4 VGA Matrix inputs using the supplied VGA cables. 2. Connect up to 4 Analog Audio sources to the 4x4 VGA Matrix audio inputs using the supplied 3.5mm mini-jack stereo audio cables. 3. Connect up to 4 VGA capable displays to the 4x4 VGA Matrix outputs using user supplied VGA cables. 4.
IR REMOTE DESCRIPTION 1. Remove battery cover from the back of the RMT-16-IR remote (see picture below). 2. Locate the DIP Switches and verify that DIP switches 1 & 2 are in the down (OFF) position. 3. Insert the battery, holding 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 RMT-16-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.
4X4 VGA MATRIX REMOTE INSTALLATION How to Resolve IR Code Conflicts In the event that IR commands from other remote controls conflict with the supplied RMT-16IR remote control, changing the remote channel will alleviate this issue. The RMT-16IR remote control has a bank of DIP (Dual Inline Package) switches (see page 7) for configuring the remote channel that both units use to communicate.
USING THE IR REMOTE CONTROL UNIT IR Remote Control Key Mapping Each input and output on the 4x4 VGA Matrix is represented by a button on the IR Remote Control unit. The table below lists the corresponding inputs and outputs.
