5. INSTALLATION AND WIRING
5.1 Installation
CAUTION: Before installation, please ensure the Matrix is disconnected from the
power source.
DUX-8D occupies 1U 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 using the mounting screws provided.
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 device. (For detailed information of wiring,
please refer to 5.3 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 the units evenly. Otherwise,
hazardous conditions may be caused by an uneven weight distribution.
CAUTION: Reliable earthing of rack-mounted equipment should be maintained.
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.
NOTE: The maximum operating temperature of the Matrix is 45°C (113°F).

USER MANUAL - DUX-8D
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 Wiring
NOTE: Please use cables provided by the manufacturer and high-quality cables
recommended by the manufacturer.
WARNING: Please ensure all the units are DISCONNECTED from power before
setting up. Otherwise, circuitry damage or physical injury may be caused.
To complete wiring of the Matrix (Please see “System Wiring” on Page 10) :
1. Connect HDMI IN: Connect HDMI IN 1-8 of the Matrix to 4K or HD source devices
(e.g. laptop, Blu-Ray player, game console, satellite/cable TV, music streaming
device, etc.).
2. Connect HDMI OUT: Connect HDMI OUT 1-8 of the Matrix to HDMI IN of 4K or HD
displays or scalers (e.g. DUX-SCL).
3. Connect HDBT OUT (for long-distance signal transmission): Connect HDBT OUT
1-4 of the Matrix to Receivers (e.g. DUX-RX or DUX-SRX).
4. Connect AUDIO OUT: Connect AUDIO OUT 1-8 of the Matrix to audio devices (e.g.
audio amplifier).
5. Connect for additional control options:
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): Connect the Matrix to the same
network as the control laptop or control system (e.g. NX-2200) via its LAN port.
c) RS232 control: Connect a control laptop or control system (e.g. NX-2200) to
RS232 port of the Matrix.
6. Power on: Connect the AC power cord provided and switch on the power button.
The Matrix is ready for operation when the front panel LEDs shows the model
name.
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
Chapter 6 “CONTROL OF THE MATRIX”.
