LIMITATIONS

• The audio input of the VOPEX-C5USBVA-4 / -8 is compatible with the following standard CPU audio outputs:

• Line out - typically lime green in color

• Speaker out- typically orange in color

• Headphone out- typically located on the CD-ROM

• The audio outputs of the VOPEX and the XTENDEX Remote Unit are compatible with self-powered stereo speakers.

PREPARATION FOR INSTALLATION

• Locations should be chosen for the monitors and speakers that also have space to connect the VOPEX and XTENDEX Remote Units within the distance provided by the cables. If extension cables are needed, contact NTI for the cables required.

• The CATx cables must be run to the locations where the VOPEX and XTENDEX Remote 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 VOPEX and XTENDEX Remote Units.

• A properly grounded, polarized, and preferably surge-protected 120V or 240V electrical outlet (de pending on the AC adapter being used) must be installed close enough to the connection location of the VOPEX and XTENDEX Remote Units, monitors, stereo speakers, and CPU 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 all devices 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.

Adjust Brightness

The brightness of the extended image can be increased or decreased by pressing the <Up Arrow> or <Down Arrow> (respectively) while in Command Mode. This adjustment is in addition to any adjustments made possible by controls on your monitor.

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 any time the XTENDEX is powered ON or if the CATx cable is disconnected and then reconnected. These adjustments can also be forced by pressing the <A> key while in Command Mode.

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 on the CD.

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.

Page 14

NTI VOPEX SERIES CAT5 USB KVM SPLITTER/EXTENDER

Fine Video Quality Adjustment

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 below. 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.

Test Patterns

To verify the need for and effect of color skew adjustment using a test pattern specifically designed for your display setting, browse the CD this manual was found on and click on the “test-pattern-nXm.pdf” file that matches your current video resolution. Follow the instructions above to make adjustments as needed.

Note: For additional quality adjustment, it may be necessary to adjust the brightness and contrast settings of the monitor.

Keyboard LEDs Indications:

Adjustment Mode NumLock CapsLock ScrollLock

Command Mode ON Blink Blink Blink Red Skew Blink Solid Solid Green Skew Solid Blink Solid Blue Skew Solid Solid Blink DDC Update Off Solid Off Command Mode OFF Normal state Normal state Normal state

Update DDC

DDC information allows the CPU to automatically select the optimal resolution for your monitor. The procedure to update DDC information (below) must be performed only once at initial setup through Command Mode (provided the monitor is not changed). Both the Local and Remote Units must be powered in order to update the DDC information. The DDC information will be based on the monitors connected to the Remote Unit and locally at the VOPEX.

To update DDC information (from Command Mode);

1. press <D> to enter DDC Update mode. (See chart above for LED indications.)

2. press the < Left Arrow> + <Right Arrow> keys simultaneously to cause DDC information to be updated

3. press <V> to return to General Video Quality Adjustment mode.

4. press <Esc> to exit Command Mode

5. Restart the CPU.

Note: It is recommended that the monitors connected to the Remote Units and VOPEX be able to support the same resolutions.

Attention: Some graphics cards will not send a video signal to the monitor until it has received the DDC information from the

monitor. In this case, the monitor may not display anything until the DDC information is read. This may occur if the monitor is being connected to the XTENDEX for the first time. The DDC information must be updated in the XTENDEX to achieve video using the procedure outlined above.

If the monitor is changed to a different model than was initially installed, the update procedure must be repeated through Command Mode.

DDC Mixing

To mix DDC information from multiple monitors (providing a table of resolutions that are common to each connected monitor), perform the update procedure above at each remote connected to a monitor that is to be added to the mix. This will provide DDC information to the CPU that is common to all connected monitors. If the resulting list of resolution options at the CPU is undesirable, to clear it and start over, power cycle the VOPEX and repeat the update procedure at the remote for each desired monitor.

Note: The DDC information from the local monitor (connected to the VOPEX) will be added to the mix if it is connected during the update procedure.

Page 15

NTI VOPEX SERIES CAT5 USB KVM SPLITTER/EXTENDER

Toggle MAC Mode

MAC Mode enables the user to connect the VOPEX to a MAC CPU. MAC Mode configures the VOPEX for passing mouse information to the MAC CPU. This is useful when the user wants to use mouse drivers provided by the mouse vendor, which allows the use of programmable functions for each mouse button. The XTENDEX can be configured whenever necessar y. Use the following procedure for each XTENDEX Remote Unit that requires the use of MAC Mode for the mouse connected to it.

In the default setting (non-MAC Mode), the VOPEX is configured for connection to a SUN or Windows CPU. To toggle between non-MAC Mode and MAC Mode, press <M> while in Command Mode. The “MAC Mode” LED on the Remote Unit will illuminate when the VOPEX is in MAC Mode.

NOTE: When the port is connected to a PC or SUN CPU, MAC Mode (and the MAC Mode LED) should be OFF.

To do this;

1. Enter Command Mode. (Simultaneously press the left and right <Shift> keys on the keyboard connected to the Remote Unit

2. If a MAC CPU is connected, press the <M> key. The keyboard LEDs will momentarily flash and the “MAC” LED on the Remote Unit will illuminate to indicate MAC Mode is ON.

To reconnect the VOPEX to a SUN or Windows CPU (the default setting), press the <W> key and the “MAC” LED will go OFF.

. The keyboard LEDs will illuminate. )

Figure 7- MAC Mode LED

Exit Command Mode

Press the <Esc> key to exit Command Mode and return to normal operation. All keyboard LEDs will return to current keyboard LED state.

FYI: Video quality will be limited by several factors. Some factors include the quality and type of CAT5 cable being used, the length of cable run, the quality of the monitor, the resolution setting of the monitor, and the quality of the video card used in the video source. If the desired level of image clarity cannot be achieved by making the adjustments described in this section, consider the following possible adjustments that can be made:

• Improve the quality of cable used -CAT5,5e,or 6 (CAT5e unshielded (UTP) cable will provide the

best performance)

• Use unshielded cable (UTP) instead of shielded cable (STP)

• Shorten the length of the cable between the remote and local

• Reduce the resolution setting on the monitor used

• Use a higher quality video card in the video source

FIRMWARE UPGRADE PROCEDURE

This procedure describes how to upgrade the firmware in this VOPEX (Models VOPEX-C5USBVUA-4/-8 only). If you are not certain whether this VOPEX has the most up-to-date firmware available, simply download the latest version and follow the upgrade procedure. All versions of firmware can be downloaded from http://www.networktechinc.com/download/d-kvm-

splitter-cat5.html .

The VOPEX and XTENDEX combination includes 3 different firmware files, two in the VOPEX (Local) and one in the XTENDEX (Remote):

1. Local Controlle r – the Local Controller will be upgraded with a binary file named vc5usbv-csx-x.bin. (where x-x is the rev number)

2. Local Port Controller – the Local Port Controller will be upgraded with a hex file named vc5usbv-cpx-x.hex.

3. Remote Controller – the Remo te Controller will be upgraded with a bin file named c5usbvu-rcsx-x.bin.

The VOPEX firmware has a bootloader which can be used for firmw are upgrades. The bootloader resides in a protected area of Flash memory, so that if the upgrade fails for any reason, the bootloader will still b e available to be used to reprogram the entire unit.

Upgrades are made to the Local Controller, Local Port Controller, or Remote Controller separately. Not all Controller firmware is updated with each revision, however it is highly recommended that if you upgrade one piec e of firmware, you upgrade each controller segment to make sure your VOPEX and XTENDEX Remote Unit(s) are all at current versions.
