Introduction
Thank you choosing this CAT5 Mini VGA Extender
Kit!

Pins and pairing. Make sure the UTP cable pin assignments are correct: straight through pin-to-pin, withpairing as follows.

When used with the Mini CAT5 VGA Extender allows
you to send a VGA signal at a distance:
up to 100 meters (330 feet) for AVK-70X-U1 Kit
or 60 meters (180 feet) for AVK-70X-S1 Kit.

Twist density.
UTP cable pairs have different twist densities (twist pitches),
which can be seen by stripping off about 10cm (4 in.) of insulation. Wire colors vary by manufacturer, do not depend on colors to guess twist densities;
strip a section and inspect.
The ABCD picture shows typical UTP cable, with pairs
A and C having high pitch twist, and B and D having low.
Most cables have two high density pairs; somehave three. Assign high density twists by priority topin pairs 1-2, 7-8, and 4-5; assign low density twists topin pairs, by priority, 3-6 and 4-5. Failure to assign
correct twist densities may result in image jitter.

Installation
1. Connect CAT5/5e/6 cable to the AV-701X-S1
Receiver UTP/STP IN connector. Connect themonitor to the VGA out connector.
2. Connect the AV-702X-U1/S1 Direct-plug
Transmitter unit to the PC VGA port, the USB
connector to a convenient USB port for AV-702XU1.
3. Connect a length of CAT5 (or CAT5e or CAT6)
UTP cable, not exceeding the maximum permittedbetween AV-701X-S1 IN port and the5 length,
Transmitter unit UTP/STP OUT port.

Gain setting (think brightness) is achieved.
6 best
The Receiver retains the adjustments.

4. Plug in the power adapter and connect it to AV701X-S1 Power connector. Go to Image Tuning.
Image Tuning
During original installation, or any time the length of
the CAT5/5e/6 UTP cable is changed, do the following:
Adjust EQ and Gain. While displaying a remote
screen on the monitor, insert the small Phillips
screwdriver (supplied) into the left hole (closerto the mouse/KB connectors) of BE-630x. Whilelooking at the VGA monitor, rotate gently till thebest EQ setting (think image focus) is achieved.
Then insert the screwdriver into the right hole(closer to Power LED), and rotate gently till theTrouble Shooting
Problem: No video
1) Make sure all cables and connectors are securely
plugged into their appropriate ports.
2) Make sure that the monitor supports the PC
transmitted resolution and refresh rates.
3) Make sure the CAT5 cable pin assignments arecorrect.
Problem: Image jitter
1) With particular attention to twist density (q.v.,
above), check twisted pairs assignments.
