Thank you for purchasing a StarTech.com VGA Cat5 Splitter/Extender. Combined with

one or more StarTech.com remote receivers (STUTPRXL - sold separately), you can

display the image from a computer or other VGA image source on multiple remote

displays at distances of up to 1000 feet (300 meters). With no drivers or software to

install, this VGA Extender offers simple setup and crystal-clear images at resolutions of

up to 1280 x 1024 pixels.

Features

• Display the image from a local computer on multiple remote displays at distances up to

1000ft (300m)

• Hardware-only solution: no drivers or software to install or configure

• Uses industry-standard Category 5 Ethernet cable

• Supports resolutions of up to 1280 x 1024 at 60Hz refresh (depends on distance of

remote displays)

Before You Begin

System Requirements

• 1 x STUTPRXL Remote Receiver module for each remote display (not provided)

• 1 x HD15 male-to-male VGA cable

• Category 5 Ethernet cable terminated at each end with RJ-45 connectors, one for

each remote display (if using surface cabling)

Category 5 Ethernet cable terminated at each end in a wall-mounted outlet, with a

standard Category 5 patch cable, two for each remote display (if using premises

cabling)

Do you need additional cables? Visit www.startech.com to find what you need and the

name of your local StarTech.com dealer.

NOTE: The total length of RJ45 cables supporting each remote display cannot exceed

1000 feet (300 meters) from the VGA Extender unit to the remote.

The VGA Extender is composed of two different units: the ST124UTPE(4-

port)/ST128UTPE(8-port) Extender and Splitter, along with a STUTPRXL Remote

Receiver (available seperately). The VGA Extender takes the output from a VGA source

(usually a computer) and transmits it to one or more Remote Receivers over Category 5

Ethernet cable. Each remote display (monitor, projector) connects to a Remote Receiver

using a standard VGA connection and displays the image from the local computer on the

remote display.

Preparing Your Site

Before you can install the VGA Extender, you need to prepare your site.

1. Determine where the local computer will be located and set up the computer.

2. Determine where the remote displays will be located, situate them appropriately.

3. If you are using surface cabling, ensure you have enough Category 5 Ethernet cabling

to connect the VGA Extender to each remote location, and that each end is terminated

with an RJ-45 connector.

If you are using premises cabling, ensure that the Category 5 Ethernet Cabling

between the VGA Extender and each remote display location has been properly

terminated in a wall outlet in each location and there is a patch cable long enough to

connect the Remote Receiver and the VGA Extender to their respective outlets.

Installing the VGA Extender and Splitter (local)

1. Place the VGA Extender (ST128UTPE/ST124UTPE) near the local computer.

2. Switch off the computer.

3. Connect the data cable from the local computer display to the OUTPUT port

on the VGA Extender.

4. Connect the HD15 male-to-male VGA cable (provided) to the INPUT port on the VGA

Extender.

5. Connect the other end of the HD15 male-to-male VGA cable to the VGA Out

connection on the local computer (originally occupied by the local computer display).

6. Connect the Ethernet cable connection for each Remote Receiver to an RJ-45

port on the VGA Extender (marked Cat. 5).

7. Connect the AC Adapter (provided with local unit) into an appropriate power

source and plug the opposite end into the DC/12V port on the VGA Extender.

Step 6 (See Below)

Installing the Remote Receiver Module

1. Connect the Remote Receiver to the Ethernet cable connection from the VGA

Extender, marked Cat. 5.

2. Connect the data cable from the display to the opposite side of the receiver,

marked VGA OUT.

3. Repeat steps 1and 2at each remote display location.

4. Connect the AC Adapter (provided with remote unit) into an appropriate power

source and plug the opposite end into the DC/12V port on the Remote Receiver.

CAUTION: The Category 5 Ethernet cables that connect the VGA Extender and Remote

Receivers carry electrical current and should not be plugged in to other devices, as they

may cause damage. We strongly recommend marking the Ethernet cables you are using

with the VGA Extender at every location for easy identification.

Completing the Installation

1: Switch on the local computer and display.

2: Switch on the display at each remote location.

3: Verify that every remote display/monitor is properly displaying the image from the local

computer connected to the VGA Extender.

The following section provides troubleshooting help. The solutions are arranged in the

order they should be attempted in most situations. If you continue to have difficulties

after attempting the solutions in this section, please contact StarTech.com technical

support.

One or more of the remote displays is black or displays a “no signal” message:

This means that the Remote Receiver is not receiving a signal from the VGA Extender.

(1) Check that the display is receiving power and that all cables are connected.

(2) Check that the display is connected to the Remote Receiver.

(3) Try an alternate RJ-45 connector on the VGA Extender.

(4) If you have a computer connected to the VIDEO IN port on the Remote Receiver,

switch it off and/or disconnect it.

One or more remote displays does not display an image when the local computer

wakes up from Standby Mode:

Power the remote displays OFF and ON again.

One or more remote displays is distorted, noisy, or displays a “signal error” or

similar error message.

The screen resolution and/or refresh rate on the local computer may be set too high for

the capabilities of the remote displays. to remedy this:

(1) Adjust the local computer to a lower resolution and refresh rate until all

remote displays show an image.

(2) Gradually increase the resolution and refresh rate on the local computer

until one (or more) remote displays ceases to display an image.

(3) Return the resolution and refresh rate on the local computer to the highest

resolution and refresh rate setting that displayed an image on all remote

displays.

NOTE: If you are still unable to see an image on a remote display after trying the above

solutions, it is recommended that you verify the Category 5 Ethernet cable installation to

the remote display before calling technical support. This can be done using a standard

cable tester. If you do not have a cable tester, contact a local computer service or wiring

professional.
