Introduction
The XTENDEX Series ST-C5VRS-600 Video and RS232 Extender is designed to enable one CPU to be viewed
or accessed by two touchscreen 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-C5VRS-600 Video and RS232 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 touchscreen monitor in a location where only this is needed without having
the CPU there too, taking up valuable space
•Allows a CPU to be accessed by both a local and remote user (up to 600 feet away)
•Compatible with XGA, VGA, and SVGA systems
•RS232 support enables the extension of a serial device (i.e. touch-screen monitor or mouse)
•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 automatic providing optimum image quality

Limitations
•RS232 devices connected to the Local and Remote Units must be identical.
•The RS232 ports on the Local and Remote Units will support serial devices other than touchscreen monitors
as follows:
•2 simple devices (i.e. mice) connected to each unit, or
•1 complex device (i.e. serial modem, RS232 command port on an NTI switch) connected to
either the Remote or Local Unit.
•Even though two users will have full access to the single CPU, if both users attempt to access the CPU at
the same time, there will be a conflict. For example, if both the local and remote users are attempting to
move the mouse pointer, it may jump around the screen and move in unintended directions.
•The maximum baud rate supported by the RS232 port is 56K bits per second and the attached CPU must
be configured accordingly.
Preparation for Installation
•Locations should be chosen for the touchscreen 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 and
Local Units 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, monitor, and RS232 device 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-C5VRS-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.

The Remote Unit
1. Position the Remote Unit such that the CAT5 cable, the monitor cable, RS232 cable, and the AC adapter
power connector can each reach the Remote Unit comfortably.
2. Connect the monitor cable to the female 15HD video connector on the Remote Unit.
3. Connect the RS232 cable from a touchscreen monitor (see Fig. 3) to the male 9D connector
on the Remote Unit.
Figure 3- Connect the Extended Components to the Remote Unit
4. Make sure the CAT5 cable has been installed in accordance with the “Preparation for Installation”
instructions on page 3. Connect the CAT5 cable to the “Cat 5” port on the Remote Unit. (See Fig. 3.)
When properly inserted the CAT5 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-C5VRS-600 Extender to an ethernet card, ethernet router,
hub or switch or other ethernet RJ45 connector of an ethernet device. Damage to devices connected

Plug-in and Boot Up
1. Plug the power cord from each monitor into a power outlet.
2. Connect the power connector from each AC adapter to the 5VDC port on the Remote and Local Units.
Make sure each power connector goes into the port all the way. Plug each 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.)
Figure 4- Connect the AC adapters to the Remote and Local Units
3. Turn ON the CPU and Monitors. They should each react as if they were directly connected to each other.
NOTE: The green LED on each RJ45 connector will illuminate anytime data traffic is passing between
the Local and Remote Units, indicating proper CAT5 cable connection and communication. (See Fig. 4)
Video Quality
Video quality adjustment is done automatically to assure the image is as clear as possible for varying lengths
of CAT5 cable.
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.
