■Operation
1. Front panel control
The MX0404-HE1 front panel control for switching inputs to the various outputs.
There are four groups of LEDs for each output port. The LED lit on the position
means that the output port selects this input as its source.

Page 6
2. Local IR remote control.
3. IR extender control
User can use the IR receiver cable to change the IR receiver position.
If controlling the MX0404-HE1 through the 1/8” (3.5 mm) input jack on the rear
panel, connect the IR cable directly to the matrix rear IR Ext socket.
User can control the
HDMI route of the matrix
by using the IR remote.
There are four group key
pads for four output port.
For each output port
source selection, there
are 4 number key and
two arrow key. Press
number key to select
specific input port. Left
arrow is to backward the
input port, and right arrow
to forward in
p
ut
p
ort.

4. IR call back control the matrix
User can control the matrix via the IR call back system.
This function can be disabled or enabled.
Enable the function: press the output2 selection button and the output4
selection button at the same time for about 3 seconds. After all the output1
LEDs and the output2 LEDs flash once, the function is enabled.
Disable the function: press the output2 selection button and output4
selection button at the same time for about 3 seconds. After all the output1
LEDS and the output2 LEDS flash twice, the function is disabled.
5. IR system could control the sources from the sinks or control the sinks from
sources.

The matrix can not only extend the HDMI signal to HDMI receiver which is in
remote rooms, but also can pass the IR signal through the IR system to the
HDMI source or pass the IR signal from the HDMI source to the HDMI sink.
There are four IR emitter sockets for connecting IR TX cable. The IR TX signal
is reversed to HDMI signal. That is, when user is watching the STB signal
which is connected to input3, the IR signal will go to the IR_TX3 socket.
Because the each IR emitter socket is related to one HDMI input port. Be sure
that the IR TX cable connected to the IR emitter socket and stick the IR emitter
to the IR window of the HDMI source device which has been connect to the
related input port. For example, STB connected to input1, and then if user
wants to control the STB via the IR call back system, plug the IR TX jack to the
IR emitter socket source1. And, stick the IR emitter near to the IR window of
the STB.
There are four IR receiver sockets for connecting IR RX cable. The IR TX
signal is forward to HDMI signal.
Press the output1 selection button and output4 selection button at the same
time for about 3 seconds. After all the output LEDS flash, the matrix go into the

Page 9
IR TX matrix switch mode. The each IR receiver socket is related to one HDBT
output port. Be sure that the IR RX cable connected to the IR receiver socket
and stick the IR emitter to the IR window of the HDMI sink device which has
been connect to the related HDBT receiver. For example, HD LCD connected
to HDBT receiver which connected the HDBT output1 of the MX0404-HE1,
and then if user wants to control the HD LCD via the IR system, plug the IR RX
jack to the IR receiver socket 1. And, stick the IR emitter near to the IR window
of the HD LCD, go into IR TX matrix mode, press output1 button to select the
first IR channel.
6. RS232 remote control.

Note: Use the direct UTP cable to connect with PC, or use cross cable to connect to the Ethernet
switcher
A. When NETCTL run on PC at the first time, it will create a file ‘NETCTL.TXT’. This file is
for device information’s backup. These information include MAC address of
MX0404-HE1, IP address, device name etc.
Double click NETCTL.exe to run NETCTL. It will search the device. If the device is a new one,
NETCTL will list it‘s IP address. If IP address appears, please click the button .
NETCTL will change the IP address to device name.
If you want to change the device name. Right-click the device name.A pull down menu will be
displayed. Click the item ‘Rename’ to rename it’s name.
B. Double click the device name, or click right button and click the ‘open’. A web browser
will be shown. The default password is "0000000000", input the password and login. The
device controller page will be displayed.

Page 13
The right area is for device controlling. Click these buttons to control the device. It is the same as
using the COM controller. The left area shows which input ports are being chosen by the output
ports.
C. When ‘Assign IP’ is displayed, it means that the device has not been assigned IP
automatically. Double click this item. Or click right button and click ‘Assign IP’ on the
pull down menu. You can assign the IP address in the Assign IP dialog.

Page 14
Click OK after assign the new IP and to return to the previous dialog. Click
and . The device can be displayed correctly.
ATTENTI ON：here assign IP is different from Set IP in COMCTL. Set IP in COMCTLis save the
IP address in flash, when the MX0404 power on, it will read the IP from flash and set it as static IP.
Assign IP function used when automatically obtain IP address failed. This assigned IP address is
not save in flash.
Switch for EDID setting. (Factory default setting: DIP in ‘010’ mode, EDID
are all 1080p and stereo.)
Position1 Position2 Position3 Function
0 0 0 copy HDMI Sink's edid to its current
selection of input port (note1)
0 0 1 1080P 3D stereo (note2)
0 1 0 1080p stereo (Using Embedded EDID)
(note3)
0 1 1 1080i stereo (Using Embedded EDID)
(note4)
1 0 0 1080p5.1(Using Embedded EDID) (note5)
1 0 1 1080p 7.1(Using Embedded EDID) (note6)
1 1 0 Reserved
1 1 1 Reserved
Note1: Copy the EDID data to the input port according to the matrix route
status. It will copy the EDID data from the output number port. For
example, when output-3 selects input-1, after pressing and holding the
Output 3 button for 3 seconds, it will copy the output-3’s EDID to input-1.
Note2: The matrix will use the embedded 1080p-stereo 3D EDID when
the DIP switch is in this mode. The EDID will be 1080p 3D video and
stereo audio. The EDID data will only be updated when powering on the
matrix.

Page 15
Note3: The matrix will use the embedded 1080p-stereo EDID when the
DIP switch is in this mode. The EDID will be 1080p video and stereo audio.
The EDID data will only be updated when powering on the matrix.
Note4: The matrix will use the embedded 1080i-stereo EDID when the
DIP switch is in this mode. The EDID will be 1080i video and stereo audio.
This setting can be used when the TV set is an old model that can not
support 1080p. The EDID data will only be updated when powering on the
matrix.
Note5: The matrix will use the embedded 1080p-5.1 EDID when the DIP
switch is in this mode. The EDID will be 1080p video and 5.1 audio. The
EDID data will only be updated when powering on the matrix.
Note6: The matrix will use the embedded 1080p-7.1 EDID when the DIP
switch is in this mode. The EDID will be 1080p video and 7.1 audio. The
EDID data will only be updated when powering on the matrix.
Examples for EDID setting:
1. How to reset EDID to factory default setting?
Because the default EDID is 1080p and stereo. So just set DIP to ‘010’ and power
on the matrix, all the EDID for input ports will be set to 1080p and stereo. After
reset the EDID data, the DIP switches can be set to ‘000’ or ‘001’ if user needs
future setting.
2. How to copy the EDID of AVR which is 7.1 audio to the special input port,
where connected a BD player?
1. Set DIP to ‘000’.
2. Connect the AVR to one of the output ports. For example, connect to output1.
3. Power on the matrix. Select the source of the AVR (for example input2) to the
input port which is connected to BD-player.
4. Press and hold the output1 key more than 3 seconds, the matrix will copy the
EDID data from output1 to input2.
