INTRODUCTION

Congratulations on your purchase of the 2X VGA Extender. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-onsolutions that harness integration, extension, distribution and conversion technologies. Gefen’s reliable,plug-and-playproducts supplementcross-platformcomputer systems, professional audio/video environments and HDTV systems of all sizes withhard-workingsolutions that are easy to implement and simple to operate.

The Gefen 2X VGA Extender

The Gefen 2X VGA Extender allows you to extend VGA video at great distances, up to 1,000 feet from the video source. A single industry-standardCAT5 cable

is used to carry the video signal. The 2X VGA receiver unit has two VGA video outputs, so you can connect more than one monitor if so desired at the remote location.

How It Works

You simply hook up the 2X VGA sender unit to your VGA video source using the supplied 6-footVGA mating cable, then run yourCAT-5cable to the 2xVGA

Receiver unit. At the remote end, connect your display(s) to the 2X VGA Receiver and your video will be extended flawlessly.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 2X VGA EXTENDER

Resolutions up to WUXGA (1920 x 1200) are supported.

Maximum extension of CAT-5orCAT-5edistance of 1000 feet (300 meters).

Display information (EDID) is not sent back to the source. Standard VESA resolutions should be output by most computers without the need of an EDID. If using a non-VESAstandard 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.

CONNECTING AND OPERATING THE 2X VGA EXTENDER

How to Connect the 2X VGA Extender

1.Connect the VGA source to the 2X VGA Extender sender unit using the supplied VGA cable

2.Connect the 2X VGA Extender sender unit and receiver unit together using a user supplied CAT-5orCAT-5ecable.

NOTE: When terminating cabling, please adhere to theTIA/EIA-568-Bspecification. Please see page 7 for more details.

3.Connect the displays to the 2X VGA Extender using user supplied VGA cables.

4.Connect the included 5V DC power supply to the 2X VGA Extender sender unit.

5.Power on the display first, and the source second. The LED indicators on both the 2X VGA Extender sending and receiving units should now be lit . The receiver unit relies on power from the sender unit. If the receiver unit’s LED indicators are not lit, please check the CAT-5cabling and ensure that a proper connection has been made.

6.If the image appears blurry or smeared, please refer to the next section for instructions on how to adjust the video image.

ADJUSTING THE 2X VGA EXTENDER RECEIVER

The 2X VGA Extender Receiver has a number of adjustment options to achieve optimal video quality. There are fine and coarse adjustments for focus and brightness. There is also individual color adjustments for cable skew. Please use the steps below to fine tune the video signal.

Trim Pot Adjustment Procedure

All adjustments in the following section are done via trim pots that require a small flathead device. Please follow the steps below for instructions on how to adjust the trim pots.

1.Insert a small flathead adjustment tool into the trim pot.

2.Turn the trim pot in a clockwise fashion until the trim pot stop turning. Do not force the trim pot beyond this point as it will render it useless.

3.Turn the trim pot in millimeter increments in a counter-clockwisefashion until the desired adjustment point is reached.

4.Remove the trim pot adjustment tool.

ADJUSTING THE 2X VGA EXTENDER RECEIVER

Brightness (AGC dip switch, Brightness trim pot)

The 2X VGA Extender receiver features an automatic gain control (AGC) for brightness. This should set the optimal brightness based on the video signal. However, manual adjustment can be done by disabling this feature. To disable AGC, remove the silver metallic tape on the underside of the 2X VGA Extender receiver to expose a 2 dip switch bank and a pair of trim pots. By default, AGC is turned on as indicated by dip switch 1 being in the ON position (Dip switch 2 is not used). Disable AGC by turning dip switch 1 to the OFF position. Adjustment to the brightness can now be done using the Brightness (Br.) trim pot, located on the back panel of the 2X VGA Extender receiver unit. Use steps 1 through 4 on the previous page to adjust the brightness trim pot.

Color Skew Correction (Red, Green, and Blue trim pots)

Varying cable quality, length, and skew may offset the convergence of the three primary colors. Red, green, and blue can individually be adjusted to compensate for cable skew. Please use steps 1 through 4 on the previous page on the trim pots for each color.

Focus (Focus and CABLE EQ trim pots)

If the image appears blurry or ghosted, the focus may need to be adjusted. Use steps 1 through 4 on the previous page on the Focus (Foc.) trim pot, located on the back panel of the 2X VGA Extender receiver unit.

The focus can be fine tuned using the CABLE EQ trim pot located on the underside of the 2X VGA Extender. Use steps 1 through 4 on the previous page to adjust the CABLE EQ trim pot.
