Series CAT5 Extender (XTENDEX) is designed to enable one CPU to be controlled by two users, one local and one remote. Extended components may include a standard monitor (or touchscreen monitor when RS232 is supported), PS/2 keyboard, and PS/2 mouse. The remote user can be located as much as 1000 feet away from a PS/2 CPU via Category 5/5e/6 unshielded twisted-pair 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 accessed by both a local and remote user (up to 1000 feet away) Compatible with XGA, VGA, and SVGA systems Provides crisp and clear resolution up to 1920 x 1200 @ 1000 feet (see page 13 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 adjustment, for varying lengths of cable, is automatic (see page 11) providing optimum image quality Built-in surge protection This manual covers each of the XTENDEX Series CAT5-1000S Extender models offered. Some features described in this manual are available in some models and not in others.

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 model 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 unit, or 1 complex device (i.e. serial modem, RS232 command port on an NTI switch) connected to either the Remote or Local Unit. The RS232 port supports all baud rates up to 57.6K bits per second and the attached CPU must be configured accordingly. 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, 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 proceeding. 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. WARNING: The CATx connection cable used between NTI XTENDEX Series Local and Remote or any XTENDEX Series products must be wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc.) The use of a CROSSOVER CABLE will damage the extender and void your warranty. 5 NTI XTENDEX Extenders INSTALLATION Installing The Local Unit 1.

Figure 6- Connect the AC adapter to the Remote Unit 3. Turn ON the CPU and Monitor. They should each react as if they were directly connected to each other. Note: The yellow 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. 6) 10 NTI XTENDEX Extenders VIDEO ADJUSTMENTS Automatic Video Quality Adjustment Video quality is broken down into “general video quality” for brightness and sharpness of the images, and “color skew” for how the colors align with each other on the monitor. Both general video quality and color skew adjustments are done automatically. The automatic video adjustments are calibrated for unshielded twisted pair cable. For shielded cable fine adjustment may be necessary and this can be done from keyboard keys using Command Mode. Video Quality Adjustment settings are automatically stored in the XTENDEX. Settings will be restored each time the XTENDEX is powered-ON. Test patterns for color skew adjustment are provided (see link below). Note: If the cable is changed after making manual video adjustments, the XTENDEX will restore these settings to factory default and fine adjustments with the new cable may be necessary. Test Patterns for Color Skew Adjustment To verify the need for and effect of color skew adjustment using a test pattern specifically designed for your display setting, go to http://www.networktechinc.com/usbkvm.html#tab-5 and click on the “test-patternnXm.pdf” file that matches your current video resolution. Follow the instructions below to make adjustments as needed. Fine Video Quality Adjustment These extenders are enabled with a Command Mode feature to perform the following: fine adjustment of the general video quality fine adjustment of color skew (alignment of red, green, and blue signals on the monitor) update DDC information between the monitor(s) and CPU Most of the video quality adjustment is automatic at power ON, but if some adjustment is necessary, this can be done using only the keyboard attached to the Remote Unit. Enter Command Mode The user can enter Command Mode using any of three different methods; Method 1 1. Press and hold the left <Shift> key 2. Press the right <Shift> key 3. Release both keys Method 2 Press and release the <Scroll Lock> key twice fast (press twice within 1 second) Method 3 Press and release the left <Shift> key twice fast, then press and release the <Esc> key once , all within 2 seconds The three keyboard LEDs (NumLock, CapsLock, and ScrollLock) will blink at the same time to indicate entrance into Command Mode. General Video Quality Adjustment Command Mode opens into General Video Quality Adjustment mode. To fine tune the general video quality, press the <Left Arrow> or <Right Arrow> keys until the desired improvement in the display has been achieved. Color Skew Adjustment If a specific color appears to be skewed and is in need of fine adjustment, the user can switch to Red, Green, or Blue Skew Adjustment mode by pressing <R>, <G> or <B> respectively. The keyboard LEDs will identify the mode as indicated in the table on page 14. Press the < Left Arrow> or <Right Arrow> keys until the desired improvement in the color alignment has been achieved. Press <V> to return to General Video Quality Adjustment mode. 11 NTI XTENDEX Extenders Update DDC at Remote To update DDC information based on the monitor connected to the Remote Unit, press <D> to enter Remote DDC mode.
