Connection Procedure
The following steps are the connections required for any installation:
1. Connect the HDMI sources to the HDMI input ports of the Matrix Switcher using good quality
HDMI cables.
2. Connect the CAT6a cable to the Matrix Switcher and HDBaseT receivers. This cable must connect
directly between the matrix switcher and the respective HDBaseT receiver.
3. Connect a display device to the HDMI output port on the matrix switcher using an HDMI cable.
4. Connect a display device to the HDMI output port on each of the HDBaseT receivers using an
HDMI cable.
5. Connect the 24V DC power supply adapter and tighten to secure. For the MUBT-88EC an IEC mains
cable is connected directly to the matrix switcher. Once all components have been connected and
the installation is complete, switch on the supply.
The following steps are optional:
1. Connect an AVR amplifier to S/PDIF output port via the TOSLINK fibre optic cable.
2. Connect a stereo amplifier with speakers to the L&R (RCA) output port using audio cables.
3. Connect an IR receiver to the IR IN sockets (3.5mm jack) on the HDBaseT Receiver and connect the
IR Emitters to the IR OUT sockets on the Matrix Switcher to make up as IR Matrix.
4. To control the matrix switcher from an RS232 port, connect the Matrix RS232 phoenix connector
to the controller RS232.
5. To control the matrix switcher using TCP/IP, connect a Cate5 network cable from the router to the
Ethernet port on Matrix Switcher.

Notes: When using IR receivers connected to IR IN, the IR carrier must be present. If it is not, then send
the RS232 command %0901. to force carrier mode (38 KHz) to ensure the IR data is sent with a
carrier signal between Matrix Switcher and far-end HDBaseT Receiver.
To revert to using the native carrier signal, send the RS232 command %900. to activate native
carrier mode.
Native carrier mode (factory default)
This mode must have the IR carrier signal present. The IR detectors supplied with the Matrix
Switcher are fully compatible with this mode setting.
Forced carrier mode
A fixed carrier of 38 KHz is forced onto the raw IR data. This mode should only be used when using
an IR detector that outputs the raw IR data without the normal carrier signal.
Using the Matrix Switcher
The input signals may be routed to either a single output, or to multiple outputs using the front control
panel or RS232 / Ethernet port commands or the remote controller.
Front panel enquiry/selection may be done by either pressing an input button first or by pressing an
output button first.
The first time any front panel button is pressed the matrix switcher provides an inquiry mode that indicates
the current port connection status. New selection can subsequently be made.
If there is no activity on the front panel button for more than 3 seconds, the matrix switcher will return to
the idle mode and turn all the button LEDs off.
Pressing an Input button first
When any input button is pressed while the matrix switcher is in idle mode, the output channel buttons
associated with that input light up as follows:
1. All the outputs associated with the selected input will light up
2. If no output buttons are off, then that input is not connected to any output
While in this mode:
1. The output buttons can be individually pressed to toggle the connection status for the selected
input (on or off).
2. A range of output channels can be selected by pressing the two start and end button of the
desired range simultaneously. For example, pressing buttons 2 and 6 will set the selected input to
outputs 2, 3, 4, 5 and 6 in one go. You may repeat steps 1 & 2 as many times as required.
Pressing an Output button first
When an output button is pressed while the matrix switcher is in idle mode, the input channel button
associated with that output will indicated the current connection status.
While in this mode, the input associated with the selected output may be changed by pressing another
input button.
Front Panel LED Status Updates
Whenever an external selection update is made to the matrix switcher, either from the RS232 port or the
LAN port, the button LEDs will light up briefly to indicate the new status.

V1.0 7www.sy.co.uk
EDID Management from Front Panel
To enter the EDID setting mode, press and hold the same input and output button pair for 2 seconds for
the input that you wish to change. The EDID setting mode is indicated by a brief flash from all the input
buttons and then the chosen input button will flash at a regular rate.
The output LEDs now indicate the current EDID setting for that input using output buttons 1 to 4 only.
Pressing another input button will show the current EDID setting for that input.
To change the EDID setting, toggle the LEDs so that they match with the state for the desired EDID mode in
the following table.

Locking / Unlocking Options
The MUBT-44EC and MUBT-88EC feature three locking methods:
1. Lock individual inputs so that it cannot be selected to any other output
2. Lock all inputs so that changes to the video selections is not possible
3. Lock the front panel so that no buttons will function
Each of the above lock options also have their corresponding unlock options.
Lock / Unlock Individual Inputs
Any input may be locked such that, at the time when the respective command is issued, that input cannot
be selected to any output that was not already showing that input. However, any output that is already
showing that input may switch to another input provided that the new input is also not locked. Any output
that was already showing the input that is being locked will remain in an unlocked state.
This option allows any input to be made private to all outputs that were already showing that input at the
time when the input lock RS232 command was issued. The commands for this option are as follows:

RJ45 Wiring
Both connectors must be wired identically to the T568B standard.
Note:
You may use cat5e, cat6 UTP (cat6 preferred) in conjunction with the HDBaseT output; however for best
performance use cat6a or cat7 (particularly in electrically noisy environments). The maximum distances &
transmission performance for HDMI and HDBT may be compromised by cable quality, patch panels, poor
termination, wall plates, cable kinks and electrical interferences. Generally ensure the cat cable is solid
copper core of 23AWG (avoid CCA type), in one straight run (avoid/minimise patches) and avoid close
proximity to any noisy electrical sources.
RS232 Commands
The following RS232 commands provide control of the SY-MUBT-44EC and SY-MUBT-88EC matrix switchers
from a PC, laptop or programmable control panel.
The RS232 settings are: 9600 baud, 8 bits, no parity, and 1 stop bit.
All response values given in the following table are examples only. The actual response values will reflect
the changes that the transmitted RS232 command has just made.
The RS232 commands are case-sensitive and all numerical values are in decimal only.
Any numerical value is always limited by the number of inputs and outputs that the matrix being controlled
has, thus:
For the MUBT-44EC the values range for inputs and outputs is 1 to 4
For the MUBT-88EC the value range for inputs and outputs is 1 to 8.
A numerical value is represented in the table with square brackets, but these brackets and the text within
should always be replaced with the required numerical value, for example:
Action: Select input 1 to output 4 for both video ant IR
Command in table: [x1]B[x2]. (Only one output is being connected)
Command sent: 1B4.
All the punctuation characters, except the square brackets, shown in the RS232 commands below are part
of the command and must be included when sending the command.
All the RS232 commands given in the following table apply to both the MUHD-44EC and the MUHD-88EC,
unless otherwise stated.
