The MuxLab HDMI 4x4 Matrix Switch, HDBT (500416-POE) allows 4 HDMI
sources to be switched/distributed to up to 4 remote displays via unshielded twisted
pair (UTP) or shielded twisted pair (STP) cables for cost-efficient connectivity.
Remote displays can be connected up to 230 feet (70 meters) @ 1080p Deep Color via
Cat 5e/6 UTP/STP cables. The Matrix Switch works in conjunction with MuxLab’s
HDMI Receiver (500454-RX or 500454-POE-RX).

The HDMI 4x4 Matrix Switch, HDBT provides a centralized HDMI switching center
via UTP/STP cables.
1. The Matrix Switch is used in conjunction with MuxLab’s UTP/STP HDMI
Receiver (500454-RX or 500454-POE-RX).
2. The Matrix Switch is typically installed in a remote telecom room and is connected
to multiple video sources and display devices via Cat 5e/6 UTP/STP or HDMI
cables. A MuxLab Receiver is installed at each display to support the connection
to the Matrix Switch via a Cat 5e/6 cable.
MuxLab’s HDMI 4x4 Matrix Switch, HDBT 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 (Figure 4).
Figure 4: Setup for Rackmount Installation
For set-top installation, the side mounting brackets may be removed, and the included
rubber feet placed on the bottom of the unit. When removing the mounting brackets,
be careful to keep and reinstall the four screws on each side of the unit (Figure 5).
The HDMI 4x4 Matrix Switch, HDBT may be manually controlled by using
pushbuttons on its front panel (Figure 8).
Figure 8: Front Panel Controls
There are four controls on the front panel of the Matrix Switch. Each control consists
of a square pushbutton that is continuously illuminated by a blue LED when the
Matrix Switch is powered. Each pushbutton corresponds to a display of the same
number (1 through 4):
Pushbutton 1: Display connected to Matrix Switch HDBT OUT 1 port (via Receiver)
Pushbutton 2: Display connected to Matrix Switch HDBT OUT 2 port (via Receiver)
Pushbutton 3: Display connected to Matrix Switch HDBT OUT 3 port (via Receiver)
Pushbutton 4: Display connected to Matrix Switch HDBT OUT 4 port (via Receiver)
Next to each pushbutton are four small LEDs (“Source LED”), which illuminate green
to indicate which source is selected for a given display. Each Source LED corresponds
to a source of the same number (1 through 4):
Source LED 1: Source connected to Matrix Switch HDMI IN 1 port
Source LED 2: Source connected to Matrix Switch HDMI IN 2 port
Source LED 3: Source connected to Matrix Switch HDMI IN 3 port
Source LED 4: Source connected to Matrix Switch HDMI IN 4 port
By pressing a given pushbutton, the user selects which source to transmit to the
display corresponding to that pushbutton.
The Matrix Switch can be controlled by a remote (Figure 9). The remote is divided
into 4 sections, with each section controlling a particular display. For any given
display, the user can choose which source to send to that display, either directly by
clicking on buttons 1, 2, 3, or 4, or indirectly by pressing on the ◄ or ► buttons to
cycle through the sources.
Figure 9: Remote
To use the remote, the user must physically aim it at the front panel of the Matrix
Switch, which contains an IR sensor to receive line-of-sight signals from the remote.
An optional IR extender cable (500999, not included) can be connected to the IR Ext
port on the rear panel of the Matrix Switch. The free end of the IR extender cable
contains an IR sensor that can be placed up to 117 centimeters (46 inches) from the
Matrix Switch, offering greater flexibility in using the remote.
The remote can also control the Matrix Switch at display locations via MuxLab
receivers. To do this, the user aims the remote at the receiver’s IR sensor and sends
command signals to the Matrix Switch. The receiver then transmits these signals to the
Matrix Switch via the UTP/STP cables connecting the receiver to the Matrix Switch.
To initiate this function, the user must simultaneously press square pushbuttons
2 and 4 on the front panel of the Matrix Switch for approximately 3 seconds. At
that point, all the Source LEDs will flash once to indicate that the remote can now be
used at display locations. To disable this function, the user must simultaneously press
the same pushbuttons for approximately 3 seconds. All the Source LEDs will flash
twice to indicate that the remote cannot be used at display locations.
Sources and displays do not have to be controlled at their physical location. Using
MuxLab receivers, each source and display can be controlled at different locations
using their respective remotes.
Using source remotes, sources can be controlled at display locations via receivers (see
Figure 6). To do so, make sure that the IR emitter cable leading from the IR Emitters
port 1 on the back of the Matrix Switch has its emitter end placed in front of IR sensor
on source 1. Do the same for all ports and all sources (see Table 3).
Table 3: Source Remote Control Configuration
Using display remotes, displays can be controlled at the Matrix Switch location via
receivers (see Figure 7). To do so, make sure that the remote of display 1 is directed at
the sensor end of the IR sensor cable leading from the IR Sensors port 1 on the back of
the Matrix Switch. Do the same for all ports and display remotes (see Table 4).
