The HDMI 4x4 Matrix Switch provides a centralized
HDMI switching center via copper UTP/STP cables.
1. The HDMI 4x4 Matrix Switch is used in conjunction
with MuxLab’s HDMI Receivers (500407 or
500417).
2. The HDMI 4x4 Matrix Switch is typically installed
in a remote telecom room and is connected to the
HDMI video source and display devices via Cat 5e/6
UTP/STP cables. A MuxLab HDMI Receiver is
installed at each HDMI display to support the
connection to the Matrix Switch via Cat 5e/6 cables.
MuxLab’s HDMI 4x4 Matrix Switch comes with
mounting brackets for standard 19” rack mounting.
Select the final destination for the product and install the
unit using standard rack-mount screws.
For set-top installation, the L-brackets on the side of the
unit may be removed and the included rubber feet
placed on the bottom of the unit. When removing the Lbrackets, be careful to keep and reinstall the four screws
on each side of the unit.
In order to install the product, please follow the steps
below:
1. Place the HDMI 4x4 Matrix Switch in its final
location.
2. Ensure that the power is turned off on the HDMI
source and displays.
3. In order to distribute the HDMI, one (1) HDMI
Receiver (500407 or 500417) must be connected at
each HDMI display. To install the Receivers,
complete Steps 4, 5, and 6.
4. Identify the pin configuration of the Receivers. Two
(2) Cat 5e/6 UTP/STP cables are required for each
HDMI connection. The pin configuration follows the
EIA/TIA 568A/B standard. The HDMI Receiver is
reverse-polarity sensitive. Please ensure that the
wiring is straight-through (Ring to Ring, Tip to Tip),
and that the two HDMI twisted pair links are not
crossed.
5. Using an HDMI cable (not supplied), plug each
HDMI source to an HDMI input of the Matrix
Switch.
6. Using an HDMI cable (not supplied), connect an
HDMI Receiver (500407 or 500417) to each HDMI
display.
7. Complete the connection between the Matrix Switch
and each HDMI display using standard straight-thru
Cat 5e/6 UTP/STP cables and connecting hardware,
terminated on RJ45 plugs at both ends. Ensure that
there are no split pairs or taps.
8. Optional: Local televisions may be connected using
HDMI cables (not supplied).
9. Power up the Receivers and HDMI equipment first.
10. Connect the external 12VDC power supply to the
Matrix Switch and plug the power supply into an AC
power outlet. If power is present, the blue power
LED will be ON.
11. Ensure that the source and appropriate display LEDs
are ON. Images should appear on the displays within
10 seconds. Check the image quality and refer to the
troubleshooting table in Section 4 if image quality is
unsatisfactory.
12. Figures 4 and 5 show some typical configurations:
Please note that Figure 5 is for users who do not require
control of the Matrix Switch from a remote location. In
such a case, MuxLab’s HDMI Receiver (500407) may
be used.
The IR Emitters included with the Matrix Switch are
used to control HDMI sources. Simply insert the plug of
an IR Emitter into any one of the 4 “IR Emitter” jacks
located on the back panel of the Matrix Switch. The
number of the jack (1, 2, 3, or 4) into which a specific
Emitter is plugged determines which HDMI Source that
Emitter will control. For example, an IR Emitter
plugged into IR Emitter jack 3 will control HDMI
Source 3.
For more information on installing and using IR
Emitters, please refer to MuxLab’s IR Emitter Quick Installation Guide.
The HDMI 4x4 Matrix Switch features built-in firmware
that allows commands from an ASCII terminal to be
sent directly to the device via either a USB or RS-232
connection (not both simultaneously). If connecting with
an RS-232 cable, ensure that the cable has the straightthrough configuration shown in Figure 6.

Port Control is performed with either the MuxLab
Control Center software, described in Section 3.7, or
with a terminal emulator such as the one available under
Windows with the ASCII Command Set described in
Appendix A. Please note that USB to RS-232 converter
cables could result in problems, depending on the
quality of the product.
The HDMI 4x4 Matrix Switch may be controlled
manually by using the push buttons located on its front
panel. Each “Display” push button controls the
particular display corresponding to its number (1, 2, 3,
or 4). By pressing on a given Display push button, the
user can choose which HDMI Source to send to that
display. The number of the HDMI Source being sent to
a particular display at any given time is indicated by an
illuminated LED next to the “Source” number (1, 2, 3,
or 4).
IR Remote Control
The Remote Control (shown on right) is divided into 4
sections, with each section controlling a particular
display. For any given display, the user
can choose which HDMI Source to send
to that display, either directly by
clicking on push buttons 1, 2, 3, or 4, or
indirectly by pressing on the left & right
arrow push buttons to cycle through
HDMI Sources. Note that when the
Remote Control is used in conjunction
with MuxLab’s HDMI Receiver
(500417), the user will only be able to
control the display which is connected
to the local HDMI Receiver.
When interfacing a MuxLab device with Windows 2000
(or more recent) operating system, a driver setup file
will be required.
To install the MuxLab Control Center software, insert
the USB flash drive into the PC. Plug the USB cable
between the device and the PC, and power up the
device. The Found New Hardware wizard will open
(Figure 7). Select Locate and install driver software.
A security window will now appear, indicating that the
driver software is unsigned (Figure 10). Select Install this driver software anyway.
Figure 10: Windows Security
A window will appear instructing that the software for
the driver has been successfully installed (Figure 11).
Click Close. You are now ready to launch the MuxLab
Control Center software.
MuxLab provides the user with software for operating
the HDMI 4x4 Matrix Switch via a PC. Each Matrix
Switch has 4 input ports and 4 output ports, and the
MuxLab Control Center software enables the user to
select which input port to feed to the output port.
To install MuxLab’s Control Center software, insert the
USB flash drive into the PC, open the folder, and double
click the SC-000032 file.
When running MuxLab’s Control Center software for
the first time, the main window will appear (Figure 12).
Figure 12: MuxLab Control Center Main Window
On the left is the Devices tree, which by default is
empty. A device may be a Matrix Switch or any other
software-controllable MuxLab product. For the purpose
of the following discussion, we will consider a Matrix
Switch as the device in question.
Once all hardware has been connected, the user must
perform the following three steps:
1. Load the Matrix Switch (automatically or manually)
2. Configure the Matrix Switch
3. Control the Matrix Switch
1. Loading the Matrix Switch
Loading consists of detecting the Matrix Switch (or any
other software-controllable MuxLab device) connected
to a PC. Loading can be done either automatically or
manually. If done automatically, every device is loaded
simultaneous by the software. If done manually, each
device must be individually loaded by the user.
Once the Matrix Switch has been successfully loaded, it
will be displayed in the Devices tree.
To load a device automatically, select Devices>Load All Connected Devices… (Figure 13).
Automatic loading detects all devices connected to the
PC, as well as the COM port on the PC to which each
device is connected.
To load a device manually, select Devices>Add Device… This loads devices one at a time, and does not
automatically detect the COM port on the PC to which a
device is connected. This COM port assignment must be
completed in the Configure Device tab. Until this
assignment is completed by the user, the loaded device
will appear in brackets as “offline” in the Devices tree
(Figure 14).
Figure 14: Offline Device
2. Configuring a Matrix Switch
Configuring a device consists of three operations:
(i) Assigning a PC COM port to the Matrix Switch
(if Matrix Switch was loaded manually)
(ii) Naming the Matrix Switch
(iii) Naming the four input ports and the four output
To configure a Matrix Switch, select the device in the
Devices tree and click the Configure Device tab (Figure
15).
Figure 15: The Configure Device Tab
If the Matrix Switch has been loaded manually, a COM
port on the PC must be selected by clicking the down
arrow next to Connect Using. The user can select a
COM port and then name (or rename) the Matrix Switch
(Device Name), its source ports (under Source Port
Names), and its display ports (under Display Port
Names).
3. Choosing a Port Selection Method
Once the Matrix Switch has been loaded and configured,
it can be controlled by the user via the Port Selection
tab. This consists of selecting which of the Matrix
Switch’s source ports will be assigned to its display
ports.
MuxLab offers users an Ethernet Web interface that
provides the same functionality as our Control Center
Software, with speeds between 10 Mbps and 100 Mbps.
For the Ethernet Web interface to function, the Matrix
Switch must first be physically connected to an Ethernet
network. To do this, locate the RJ45 Ethernet jack on
the back panel of the Matrix Switch, then connect it to
an Ethernet network using a straight UTP cable (max.
length 333 ft [100 m]). There are two LEDs at the top of
the RJ45 Ethernet jack: A yellow LED will go on if a
link is detected, and a green LED will blink if Ethernet
activity is detected.
Once the Matrix Switch has been physically connected
to an Ethernet network, go to http://AAA.BBB.CCC.DDD
(where AAA.BBB.CCC.DDD is the IP address assigned
to the device).
The home screen presents users with the option of using
a password (Figure 18).
Passwords are blank by default, meaning that the user
just needs to click on Enter when logging on for the
first time.
NOTE: Users who have previously logged on and
chosen a password, but subsequently forgot it, may click
on Forgot your password? in order to retrieve it.
The main window now appears (Figure 19). It contains
four tabs and a Log out button. The Connection Status
tab is active by default.
Figure 19: Connection Tab Screen
The Connection Status tab screen allows the user to
understand how sources are mapped to displays. The
Connection On Off radio buttons on the top left of the
tab screen allows the user to halt communication
between the Web interface and the device.
The Setup tab screen (Figure 20) allows the user to
perform three kinds of operations. On the top left, the
user can name devices, sources, and ports. Please note
that names must alphanumeric and no more than 20
characters long.
If a Static IP was used, the dialog box shown in Figure
22 will appear.
Figure 22: IP Address Assigned by User
In order to determine an IP address, the user must go to
a terminal program and type ipconfig. Note that the
terminal program uses either a USB or RS-232 serial
port.
To determine if DHCP mode is enabled, the user must
type DHCP. By default, it is enabled.
HDMI 4x4 Matrix Switches may be cascaded in order to
send an HDMI signal to more than four (4) displays. In
fact by using the local output ports of the Matrix Switch,
in theory an unlimited number of Matrix Switches may
be connected in a daisy-chain configuration. This is
possible because a clean video signal is regenerated at
each Matrix Switch.
In more practical terms, up to four (4) Matrix Switches
may be cascaded to create a 4x16 matrix. These units
would typically be connected in the following way:
When cascading multiple Matrix Switches to create a 4
x n matrix, it is recommended to name the ports on
every Matrix Switch. All the input port names of the
matrices should be the same in regards to a given
source. For example, imagine an HDMI source
designated as “Blu-Ray DVD,” and connected to Input
Port 2 of the first Matrix Switch in the chain. Input Port
2 on every other Matrix Switch in the chain should also
be designated as “Blue-Ray DVD.” Each display port
name of every Matrix Switch must have a unique name
that represents the location of the display (e.g. “Dinner
Room, East Wall”). The name of every Matrix Switch
should also be unique and indicative of its location.
In terms of the actual physical connections required to
cascade multiple Matrix Switches, please follow the
steps below:
1. Use an HDMI cable to connect HDMI Source 1 to
Input Port 1 of the first Matrix Switch in the chain
(“Matrix Switch 1”).
2. Use an HDMI cable to connect HDMI Source 2 to
Input Port 2 of Matrix Switch 1
3. Repeat Step 2 for more HDMI sources and the
remaining input ports of Matrix Switch 1. The
HDMI sources are now all connected to Matrix
Switch 1.
4. Use STP/UTP cables to connect the Output Ports on
Matrix Switch 1 to the HDMI Receivers (500417 or
500407) located at the Remote Displays for Matrix
Switch 1. (This procedure is the same as when
connecting a Matrix Switch to Remote Displays in a
non-cascaded setup.)
Now to connect Matrix Switch 1 to the second Matrix
Switch in the chain (“Matrix Switch 2”).
5. Use an HDMI cable to connect the Local Out 1 port
on Matrix Switch 1 to Input Port 1 of Matrix Switch
2. HDMI Source 1 can now transfer signals to
Matrix Switch 2.
