LIMITATIONS

• The use of CAT5e or of any stranded cabling will reduce the maximum distance and resolution.

• When a USB printer is connected to the Remote Unit, if more than 3 pages are printed at a time or if the printer runs out of

paper while printing, performance may become unreliable and the Remote Unit may need to be power-cycled to resume
operation.

• A connected USB printer may take up to 1 minute to respond to a printing request.

PREPARATION FOR INSTALLATION

• Locations should be chosen for the monitor that also has space to connect the Remote unit 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 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 video source 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 reconnection procedures before proceeding.

• Be very careful not to obstruct the air vents on the Remote Unit in its installed location.

FIRMWARE UPGRADE PROCEDURE

This procedure describes how to upgrade the firmware in this XTENDEX. If you are not certain whether this XTENDEX 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/hdmi-usbkvm-hdbt.html

The XTENDEX has 3 types of micro-controllers:

1. Local Controller – the Local Controller will be upgraded with a binary file named c6usbhe-lcsx-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 c6usbhe-lcpx-x.hex.

3. Remote Controller – the Remote Controller will be upgraded with a binary file named c6usbvhe-rcsx-x.bin.

The XTENDEX firmware has a bootloader which can be used for firmware upgrades. The bootlo ader resides in a protected area
of Flash memory, so that if the upgrade fails for any reas on, the bootloader will still be available to be used to re-progr am the
entire unit.

Upgrades are made to the Local Controller, Local Port Controller or Remote Controller s eparately. Not all Control ler firmware is
updated with each revision, however it is highly recommended that if you upgrade one piece of firmware, you upgrade each
controller segment to make sure your Local and Remote are both at current versions.
