NTI XTENDEX 300 Foot Extenders

INTRODUCTION

The XTENDEX Series CAT5 Extender (XTENDEX) is designed to enable one CPU to be controlled by two users, one local and one remote. The remote user can be located as much as 300 feet away from a PS/2 CPU via Category 5 unshielded twistedpair cable. The local user will be located near the CPU.

The XTENDEX Series Extender is extremely simple to install and has been thoroughly tested to insure reliable performance. Through the use of Category 5 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 computer peripherals (monitor, keyboard, and mouse) in a location where

only these parts are needed without having the CPU there too, taking up valuable space

• Allows a PS/2 CPU to be acc essed by b oth a local and remote user (up to 300 feet away)

• Compatible with VGA and XGA systems

• Provides crisp and clear resolution up to 1280 x 1024 @ 300 feet (see page 11 for more details)

• Compatible with all NTI switches and splitters, enabling the joining of products to create a system that

satisfies all networking needs

• Video quality, for varyin g lengths of cable, is manually adjustable ( see page 10) providing optimum image

quality

• Audio frequency response is 20Hz to 20Khz, + 1dB (models with audio support only)

• Digital transmission of au dio signals reduces any loss in quality (models with audio support only)

This manual covers each of the XTENDEX Series CAT5-300 Extender models offered. Some features described in this manual are available in some models and not in others. The chart below shows the features supported in each:

LIMITATIONS

• Hot-plugging of devices is supported provided devices were originally connected at power-up.

• In order for two users to share a PS/2 CPU, the user in control must pause for at least 3 seconds before another user can

take control. After the 3 second pause, either user can take control of the CPU.

For models with audio support:

• The audio input of the XTENDEX with audio support is compatible with the following standard CPU aud io outputs:

• Line out - typically lime green in color

• Speaker out- typically orange in color

• The audio output of the XTENDEX with audio support is compatible with self-powered stereo speakers.

For models with RS232 support:

• 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

• 1 complex device (i.e. serial modem, RS232 command port on an NTI switch) connected to

either

• In order for two users to share a PS/2 CPU, the user in control must pause for at least 3 seconds before another user can

take control. After the 3 second pause, either user can take control of the CPU.

• The RS232 port supports all baud rates up to 56K bits per second and the attached CPU must be configured accordingly.

• Headphone out- typically located on the CD-ROM

unit, or

the Remote or Local Unit.

Page 7

NTI XTENDEX 300 Foot Extenders

PREPARATION FOR INSTALLATION

• Locations should be chosen for the monitors, mice, and keyboards 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, fluorescent lighting, etc.).

• 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 monitors 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 procee ding.

• Local and Remote Units should be grounded through either a display or source that uses a 3-prong power cord. If only one

unit is grounded, shielded CAT5 cable should be used.

Note: CAT5 connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series products should not be run underground, outdoors or between buildings.

WARNING: Outdoor or underground runs of CAT5 cable could be dangerous and will void the warranty.

Connect the CAT5 cable

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 Figure 4.) 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 XTENDEX 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.

VIDEO QUALITY ADJUSTMENT

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 turn the "Video Adjust" screw on the Remote Unit to equalize the signal between the Local and Remote Units. Turn the "Video Adjust" screw using a very small screwdriver (see Figure 13) until the image is crisp and clear. Turn the screw counterclockwise if the image is not crisp and clear enou gh. Turn the screw clockwise if the image has been over-corrected (such that horizontal lines appear to trai l or shadow at the edge of an open window). A very small amount of rotation will make a minor change in the image. Ultimately, the image quality should improve to a satisfactory level.

Note: When the cable is longer than 150 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.
