PREPARATION FOR INSTALLATION
Locations should be chosen for the monitor and video source that also have space to connect the Remote Unit and Local Unit
units within the distance provided by the CATx cables.
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 re-connection procedures before proceeding.
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.

PC is being extended, also connect a USB cable between the PC and the Local Unit.
2. Connect a display to the HDMI port on the Remote Unit using one of the cables recommended in the chart on page 1. If
applicable, connect a keyboard or mouse to the USB ports.

IR Connection
The ST-C6USB4K18GB-HDBT230 supports Bi-directional IR pass back. A user can control devices at each end of the
installation. With an IR Emitter and IR Receiver connected at each end, a user can control a TV connected at the Remote Unit
and the DVD player connected to the Local Unit.
Place the IR Emitter close to the device it controls to best transmit the IR signal coming from the remote control. The remote
control at the Local Unit will control the display device on the Remote Unit, and the remote control at the Remote Unit will control
the video source at the Local Unit.
