INTRODUCTION
The XTENDEX Series ST-C6USBH-300 CAT6 HDMI Extender (XTENDEX) provides remote KVM (USB keyboard, USB mouse
and HDMI monitor) access to a USB computer up to 300 feet over CAT5e/6/6a/7 cable. Each extender consists of a local unit that
connects to a USB computer and a remote unit that connects to an HDMI monitor and USB keyboard and mouse as much as 300
feet away via Category 5e,6, 6a or 7 twisted-pair cable.
The XTENDEX Series Extender is extremely simple to install and has been thoroughly tested to insure reliable performance.
Through the use of CAT5e/6/6a/7 (CATx) 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:

•Supports HDTV resolutions to 1080p and computer resolutions to 1920x1200 (WUXGA).
•HDMI features supported:
o12-bit Deep Color
oxvYCC.Color Space
oDolby TrueHD, DTS-HD Master Audio, Dolby Digital, and DTS
oBandwidth up to 225 MHz (6.75 Gbps)
oSupport for CEC (consumer electronic control) compatible devices.
oLip Sync
•HDCP compliant.
•Supports the DDC2B protocol.
•High quality, rugged steel construction with durable powder coat finish.
•Keyboard and mouse are hot-pluggable.
•Keep-alive keyboard/mouse emulation for flawless operation.
•Only one power supply is necessary. (Power supply can be connected to either the local or remote unit.)

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

INSTALLATION
Installing The Remote Unit
1. Position the Remote Unit such that the CATx cable, the monitor cable(s), and device cables can each reach the
Remote Unit without putting strain on the cables.
2. Connect a HDMI-xx-MM (or DVI-HDMI-xx-MM cable depending upon what connector your display will accept) to the
female HDMI video connector labeled "HDMI Out" on the Remote Unit.
3. The keyboard and mouse cables can be plugged into the USB ports.
4. If your monitor is a touchscreen monitor with USB interface, and if you have an XTENDEX model with extra USB port
(as seen below), the USB cable from the monitor can be connected to one of the USB ports. This extra port can
also be used to connect a Whiteboard or CAC reader.
Note: Only models with the extra USB port present (models ST-C6USBHU-300 or ST-C6USBHU-IR-300) will support the
use of a touchscreen monitor, CAC reader, or Whiteboard.

Installing The Local Unit
1. Connect an HDMI-3-MM (supplied) or DVI-HDMI-xx-MM cable (page 2) between the CPU and the "HDMI In" connector on the
Local Unit.
2. Connect a USB2-AB-1M-5T USB cable (supplied) between a USB port on the CPU and the “USB CPU” connector on the Local
Unit.
Figure 2- Connect the XTENDEX Local Unit to the source
Connect the CATx Cables
Connect the CATx cable between the “CATx” ports on the Local
and Remote Unit. (See Figure 3) When properly inserted the
cable ends should snap into place.
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.

Plug-in and Boot Up
1. Plug the power cord from the monitor into the power outlet.
2. Connect an AC adapter power connector to the 24VDC port on either the Remote Unit or the Local Unit. Plug the AC
adapter into a power outlet. The green LED on the RJ45 connector of both the Remote and Local Units should illuminate,
indicating that a proper power connection has been made to them. (See Figure 4)
3. Turn ON the CPU and monitor. The yellow LED on both the Local and Remote Units should illuminate. The CPU, monitor ,
keyboard and mouse should each react as if directly connected to each other.

INFRARED CONTROL
Model ST-C6USBH(U)-IR-300 includes ports for connecting an infrared emitter and receiver (included) to work in conjunction with
the IR remote control used to operate the CPU. Connect the receiver to the “IR IN” port on the Remote Unit and the emitter to
the “IR OUT” port on the Local unit. Position the end of the receiver such that the signal from the remote control can easily reach
the IR sensor. Position the end of the emitter such that the extended signal can be sent to the CPU.

Note: The IR Emitter and Receiver work within a frequency range of 33-40kHz. Check the
specifications for the device you are extending to make sure the XTENDEX will work with it.

MAC MODE
MAC Mode enables the user to connect the Local Unit to a MAC CPU. MAC Mode configures the Local Unit 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 Local Unit can be configured whenever necessary.
NOTE: When the port is connected to a PC or SUN CPU, MAC Mode should be OFF (the default setting).
To do this;
1. Enter Command Mode. (Simultaneously press the left and right <Shift> keys on the keyboard. The keyboard LEDs
will illuminate.)
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. (See Figure 6)
3. To reconnect the XTENDEX to a SUN or Windows CPU (the default setting) , enter Command Mode again and press
the <M> key again and the “MAC” LED will go OFF.
4. Press <Esc> at any time to exit Command Mode.
Figure 6- MAC LED
After setting, the configuration is stored in memory and will be retrieved whenever the XTENDEX is powered ON.
