5. INSTALLING AND WIRING
5.1 Installing DUX-12F
CAUTION: Before installation, please ensure the Matrix is
disconnected from the power supply.
DUX-12F Switching Matrix occupies 3U space and can be placed on a solid
and stable surface or installed on a standard equipment rack.
To install the Matrix on an equipment rack:
1. Discharge any static electricity from your body by touching a grounded
metal object.
2. Position and install the mounting brackets provided to the front panel.
Equipment Rack
Screw fix the front panel
of DUX-12F to the rack
1U space
1U space
Brackets attach at the side
toward the front of the Matrix
3. Install the Matrix in the mounting rack by using the mounting screws to
affix the Matrix to the rack.
4. Connect any applicable wires to the Matrix. (For detailed information of
wiring, please refer to "5.4 Wiring".)
CAUTION: DO NOT place other units directly on top of the Matrix
when it is rack mounted, as this will place excessive strain on the
mounting brackets.
CAUTION: When adopting rackmouting, distribute all the devices
evenly. Otherwise, hazardous conditions may be caused by an uneven
weight distribution.
CAUTION: Reliable earthing of rack-mounted equipment should be
maintained.

12 DUX-12F
USER MANUAL
5.2 Ventilation
ALWAYS ensure the Matrix is adequately ventilated. Do not block any
ventilation openings. Sufficient airflow must be achieved (by convention or
force-air cooling) to satisfy the ventilation requirements of all the equipment
installed within the rack.
Equipment Rack
1U open space
1U open space
Brackets attach at the side

NOTE: The maximum operating temperature of the Matrix is 45°C
(113°F).
NOTE: The Matrix shall not be installed in enclosed spaces. It is
recommended that you leave 1U space above the Matrix when you
install it in a rack.
5.3 Installing Input and Output Boards
With a DUX-12F, you may build up a switching system of up to 11 (inputs) x
1 (output) or 1 (input) x 11 (outputs) by a combined use of the DUX Series
HDMI / HDBaseT input and output boards. (For more information about these
HDMI and HDBaseT input and output boards, please refer to their respective
technical document.)
The basic rule below should be followed while installing the DUX Series HDMI
/ HDBaseT input and output boards to the DUX-12F:
If the quantity of input boards (including HDMI & HDBT input boards)
is M, the quantity of output boards (including HDMI & HDBT output
boards) is N (M≤11, N≤11, M+N≤12), then
1) Insert all the input boards to slot 1 to M of the Matrix;
2) Insert all the output boards to slot M+1 to M+N of the Matrix.

13
DUX-12F
USER MANUAL
For instance, to install a DUX-12F with 6 x DUX-F-I-HDMIs (HDMI
input board), 2 x DUX-F-I-HDBTs (HDBaseT input board), 2 x DUX-F-
O-HDMIs (HDMI output board), and 2 x DUX-F-O-HDBTs (HDBaseT
output board):
1) Insert all the DUX-F-I-HDMIs and DUX-F-I-HDBTs to slot 1 to 8;
2) Insert all the DUX-F-O-HDMIs and DUX-F-O-HDBTs to slot 9 to
12.
5.4 Wiring
After successful installation of HDMI and HDBaseT input and output boards,
all the devices can be connected to the DUX-12F.
The wiring guidance below is based on a 8x4 DUX-12F Switching Matrix
installed with
• 6 x DUX-F-I-HDMIs (HDMI input board),
• 2 x DUX-F-I-HDBTs (HDBaseT input board),
• 2 x DUX-F-O-HDMIs (HDMI output board), and
• 2 x DUX-F-O-HDBTs (HDBaseT output board).
NOTE: Please use cables provided by the manufacturer and high-
quality cables recommended by the manufacturer.
WARNING: Please ensure all the devices are DISCONNECTED from
power before setting up and making any wiring changes. Otherwise,
circuitry damage or physical injury may be caused.
To complete wiring of the Matrix (Please refer to "DUX-12F WIRING CHART"
on page 15) :
1. Connect HDMI IN: Connect 4K or HD source devices (e.g. laptop, Blu-ray
player, game console, satellite/cable TV, music streaming device, CCTV,
etc.) to the HDMI IN ports.
2. Connect HDBT IN: Connect HDBT transmitters to the HDBT IN ports.
3. Connect AUDIO IN: Connect audio source devices (e.g. mixer &
microphone, DVD player, etc.) to the analog AUDIO IN ports.
4. Connect HDMI OUT: Connect 4K or HD display devices to the HDMI OUT
ports.
5. Connect HDBT OUT: Connect HDBT receivers to the HDBT OUT ports.
6. Connect AUDIO OUT: Connect audio playback devices (e.g. amplifier &

14 DUX-12F
USER MANUAL
speaker system) to the digital or analog AUDIO OUT ports.
7. Connect for control. Please select one of the following control methods.
a) IR control: The IR Remote provided is for controlling the Matrix
through infrared signal. If IR extension is required, connect the IR
Receiver Cable provided to the IR EXT port of the Matrix and position
the receiver eye in a place accessible to the Matrix Remote.
b) LAN control (through Web UI or Telnet APi Command): Connect the
Matrix to the same network as the control PC or control system (e.g.
NX-2200) via its LAN port.
c) RS232 control: Connect a control PC or control system (e.g. NX-
2200) to RS232 port of the Matrix.
8. Power on: Connect the AC power cord provided and switch on the Matrix
by pressing the power button (on the front panel). The front panel LEDs
will display the model name of "-DUX-12F-" , then show "1 1 1 1 1 1
1 1 1 0 0 0 0" and "1 2 3 4 5 6 7 8 9 10 11 12" alternately.
9. Get ready for operation: When the LEDs 9-12 show the individual input
(1-8) selected for each output (1-4) (Note: if the Matrix is operated for
the first time, the LEDs 9-12 show "1 2 3 4"), the Matrix is ready for
operation.
NOTE: ALWAYS power off the Matrix before plugging or unplugging
any cables.
NOTE: Please follow the "LAST ON FIRST OFF" rule when turning on
and off the system.
Now you can switch between sources and displays by using the Matrix
through either IR Remote, front panel, RS232 or LAN. For detailed control
instructions, please refer to "6. CONTROLLING".

6. CONTROLLING
DUX-12F Switching Matrix is designed with ease of connection and control
in mind. When the Matrix is connected and powered on, you can choose
the optimal way to control the unit at your convenience, either through Front
Panel, IR Remote (IR Receiver can be connected when the Matrix is less
accessible), LAN (for Web UI or Telnet) or RS232.
The following chapters will explain the basic instructions of the above control
methods and are based on a 8x4 DUX-12F Switching Matrix installed with
• 6 x DUX-F-I-HDMIs (HDMI input board),
• 2 x DUX-F-I-HDBTs (HDBaseT input board),
• 2 x DUX-F-O-HDMIs (HDMI output board), and
• 2 x DUX-F-O-HDBTs (HDBaseT output board).
6.1 Control through Front Panel

2) Press "2" from "STEP 2", the the LED 9 shows "2" in solid state.
System Code Switch
The IR Remote provided with the Matrix is shipped in
"00" IR system code. In the event the Remote’s IR signal
interferes with other IR devices, e.g. TV, DVD player, the
Remote can be switched to "4E" code by short-pressing
the System Code Switch button. At the same time, you
may redefine the IR system code of the Matrix using the
API command (please refer to 16 & 17 API command in
"Appendix 1: API Command").
6.3 LAN Control (via Web UI)
When connected to a LAN, DUX-12F can be controlled through either Telnet
or the tailor-designed Web UI. For advanced users who opt to control via
Telnet, API command set is available in "Appendix 1: API Command". For
users who prefer intuitive control, the Web UI will be the option.
The Web UI designed for the Matrix allows basic controls and advanced
settings of the Matrix and can be accessed through a modern browser, e.g.
Chrome, Safari, Firefox, Opera, IE10+, etc.
DUX-12F comes with a default IP address of 192.168.10.254 and Subnet
mask of 255.255.0.0. Default login password for Web UI is "admin".
