Introduction
Introduction
The XTENDEX Series ST-C5V-600 Video Extender is designed to enable one CPU to be viewed by two
monitors, one local and one remote. The remote monitor can be located as much as 600 feet away from a CPU
via Category 5 unshielded twisted-pair cable. The local monitor will be located near the CPU.
The XTENDEX Series ST-C5V-600 Video Extender is extremely simple to install and has been thoroughly
tested to insure reliable performance. Through the use of Category 5 unshielded twisted-pair cable it is possible
to economically increase the flexibility of a computer system. Here are some of the features and ways this can
benefit any workplace:
• Allows the placement of a monitor in a location where only this is needed without having
the CPU there too, taking up valuable space
• Allows a CPU to be viewed by both a local and remote user (up to 600 feet away)
• Compatible with XGA, VGA, and SVGA systems
• Provides crisp and clear resolution up to 1280 x 1024 @ 600 feet
• Compatible with all NTI video switches and splitters, enabling the joining of products to create a
system that satisfies all networking needs
• Video quality is manually adjustable to provide optimum image quality

Preparation for Installation
Preparation for Installation
• Locations should be chosen for the monitors that also have space to connect the Remote and Local Units
within the distance provided by the cables. If extension cables are needed, contact NTI for the cables
required.
• The CAT5 cables must be run to the locations where the Remote and Local Units will be connected. Be
careful to route the cables away from any sources of magnetic fields or electrical interference that might
reduce the quality of the video signal (i.e. AC motors, welding equipment, etc.). NOTE: If CAT5 cable is
already installed in the wall and there are RJ45 wall outlets, it will be necessary to obtain male-to-male
straight through connection cables long enough to reach from the wall outlets to the connection locations of
the Remote and Local Units.
• A properly grounded, polarized, and preferably surge-protected 120V or 240V electrical outlet (depending
on the AC adapter being used) must be installed close enough to the connection location of the Remote
Unit and monitors to plug them into.
• All cables should be installed in such a way that they do not cause stress on their connections to the
equipment. Extended lengths of cable hanging from a connection may interfere with the quality of that
connection. Secure cables as needed to minimize this.
• Properly shut down and disconnect the power from the CPU and monitor to be separated. If other
equipment is involved whose connections are being interrupted, be sure to refer to the instruction manuals
for that equipment for proper disconnection and re-connection procedures before proceeding.

3. Connect the CAT5 cable to the “Cat 5” port on the Local Unit. (See Fig. 2.) When properly inserted
the cable end should snap into place.
Note: If an RJ45 wall outlet is being used, connect the other end of the extension cable to the
RJ45 wall outlet.

WARNING: Never connect the ST-C5V-600 Extender to an ethernet card, ethernet router,
hub or switch or other ethernet RJ45 connector of an ethernet device. Damage to devices connected
to the ethernet may result.

Plug-in and Boot Up
Plug-in and Boot Up
1. Plug the power cord from each monitor into a power outlet.
2. Connect the power connector from the AC adapter to the 9VDC port on the Remote Unit. Make sure the
power connector goes into the port all the way. Plug the AC adapter into a power outlet. The yellow LED
on the RJ45 connector on the Remote and Local Units should illuminate, indicating that a proper power
connection has been made to both. (See Fig. 4.)
Note: The Local Unit is powered by the Remote Unit.

Video Quality
( I n s i d e
b a r r e l )
Adjust the Video Quality
It is possible that on initial startup the image on the monitor will not be as crisp as the image normally is. This is
due to the frequency characteristics of the CAT5 cable. It may be necessary to press the "+" or "-" buttons
(see Fig. 5) until the image is crisp and clear. Press the "+" button if the image is not crisp and clear enough.
Press the "-" button if the image has been over-corrected (such that horizontal lines appear to trail or shadow at
the edge of an open window). A momentary press of either button will make a minor change in the image. If
either button is pressed and held, the changes made will be gradual and continuous. Ultimately, the image
quality should improve to a satisfactory level. Once the adjustment is made, it should not be necessary to
change it again as the new settings are stored in memory and become the default settings with each startup.

Note: When the cable is longer than 300 feet some colored lines can be seen at the black-to-white
transitions. This is a normal behavior and is caused by the different twisting rates of each pair of wires
in the CAT5 cable.
