100-METER HDBT EXTENDER TRANSMITTER
INTRODUCTIONS
DUX-MTX is an HDBT Extender Transmitter accommodating both VGA and HDMI Inputs
and is able to transmit 1080P@60Hz with 48 bit Deep Color HD Audio up to 100m/328ft
and Ultra HD 4K signal up to 70m/230ft.
DUX-MTX features an automatic switching between VGA Input and HDMI Input, with
HDMI Input enjoying the priority when both Inputs are active.
A/V transmission, bi-directional IR and RS232 control and Ethernet pass-through over
one signal Cat6a/7 cable provides an added level of convenience. A CONFIG Switch
allows users to quick change its operation mode for data transmission or firmware
upgrading. An EDID Switch is also available for immediate EDID setting adjustment while
communication or compatibility becomes an issue.
Fully compliant with HDMI 1.4, compatible with HDMI 2.0 and HDCP 2.2, DUX-MTX
offers an excellent solution to commercial or residential environments where switching
between VGA and HDMI over distance is required.

INSTALL HARDWARE
WARNING:
 Before installation, disconnect the power supplies of all the devices.
 Please use quality cables and accessories specified or provided by the
manufacturer.
 During installation, connect and disconnect cables with caution.
To install DUX-MTX (See Application Example: System Wiring on Page 13):
1. Connect DUX-MTX’s HDMI IN or VGA IN to an HDMI or VGA input source (e.g.
Blu-ray player, game console, satellite/cable TV, computer, media server, etc.)
through a quality HDMI or VGA cable. (AUDIO IN may also be connected when
VGA IN is in use.)
2. Connect DUX-MTX’s HDBT OUT to an HDBT Receiver (e.g. DUX-RX) via a high-
quality CatX cable.
3. Connect an HDMI display device (e.g. TV or projector) to HDMI OUT of the HDBT
Receiver.
4. Connect IR Broadband Receiver to IR IN and IR Emitter to IR OUT of DUX-MTX.
5. Connect IR Broadband Receiver to IR IN and IR Emitter to IR OUT of the HDBT
Receiver.
6. Connect the included power adapter to DUX-MTX.
7. Power on all the devices and start operation.
NOTE:
1) When transmitting an Ultra HD signal, please ensure all the source and display devices are 4K
compatible by checking their respective input and output compatibility.
2) 70m/230ft @4K or 100m/328ft @1080p are maximum transmission distances realizable
when DUX-MTX and other devices are in perfect conditions and the straight cable runs with no
electrical interference, bends, kinks, patch panels or wall outlets, etc. If any of these turns to be
an issue in your installation, transmission distance will be affected.
3) When all set, check the LED indicators of DUX-MTX. For LED indication, please refer to page
08.

OPERATE WITH IR
DUX-MTX allows IR pass-through over HDBaseT. Hence, you can either control the
source from the display location or control the display from the source location.
To realize such function, an HDBT Receiver like DUX-RX needs to be installed.
Control the Display
To control the display from the source:
1. Connect Broadband IR Receiver to IR IN of DUX-MTX;
2. Connect IR Emitter to IR OUT of DUX-RX.
When all set, the display can be controlled at the source end through a display remote.

RS232 for Serial Communication
RS232 port of DUX-MTX can also be used for serial communication while working with
a Receiver device like DUX-RX.
To start serial communications between DUX-MTX and a Receiver device (e.g. DUX-RX):
1. Switch CONFIG Switch to “RS232 Pass-through” mode (See Page 10 “CONFIG
SWITCH”.);
2. Connect a RS232 Device (RS232 Device 1) to RS232 port of DUX-MTX using a
RS232 cable;
3. Connect another RS232 Device (RS232 Device 2) to RS232 port of the Receiver
using a RS232 cable;
4. Connect HDBT OUT of DUX-MTX and HDBT IN of the Receiver using a CatX cable.
5. When all set, the RS232 Device 1 can be controlled at RS232 Device 2 or vice versa.

• Check that the Link LED is steady on. For more information, see Q2 above.
• Check that the display works properly, and that the source device has normal signals
output.
• Ensure that the display device supports HDCP.
• Ensure the CatX cable and the HDMI cables used complies with the recommended specifi-
cations. For more information, see CABLE SPECIFICATIONS.
• Check that your display device is switched to the correct source input mode.

• Check that all the cables are qualified and connected properly.
• Check that Ethernet cables are Cat5e/6 or higher gauge.
• Check that the source input device has no such problem as snow, mosaic or with a dam-
aged disc. If so, replace with another qualified input source.
• Check that no compatibility issue exists between the Receiver and the display. If so,
replace the display with qualified models.
5. Why the firmware upgrading failed?
• Check that the CONFIG Switch is in the correct mode (MCU or HDBT Upgrading mode).
