Configuring the SY-MMU Range of Matrix Switchers
The input and output cards requested at time of purchase should already be installed in the matrix
switcher upon receipt. If this is not the case please contact your local dealer or SY directly to have this
problem addressed.
Figure 6 - DVI Input and Output Cards
The input card can either accept HDMI or DVI signals, whereas the output card will output HDMI or DVI
signals from any input card.
Figure 7 –Seamless DVI Input and Output Cards
The input card can either accept HDMI, DVI, VGA, YPbPr or C-Video signals, whereas the output card will
output HDMI, DVI, VGA, YPbPr or C-Video signals signals from any input card. Both these card support
seamless switching.
Figure 8 - VGA Input and Output Cards
The input card can only accept VGA, YPbPr, S-Video or composite video signals as well as analogue audio,
whereas the output card will only output VGA video and analogue audio signals from any input card.

Figure 9 - SDI Video Input and Output Cards
The input card can only accept SDI video signals, whereas the output card will output SDI video signals
from any input card.
4Kx2K Input and Output Cards
Any 4K input or output card can be identified by the 4K icon on the outer edge of the connector panel.
Figure 10 - HDMI Input and Output Cards
The input card can either accept HDMI or DVI signals as well as analogue audio, whereas the output card
will output HDMI or DVI signals and analogue audio from any input card.
Figure 11 - HDBT Input and Output Cards
The input card accepts HDBT and analogue audio signals, whereas the output card will output HDBT and
analogue audio signals from any input card.

SY-MMU-88A / 1616 / 3232 / 6464

The input card can only accept optical fibre signals, whereas the output card will output optical fibre
signals from any input card. Both these cards support single-mode or multi-mode fibre cables terminated
in LC fibre connector. The transmission distance is up to 300m when used with OM3 multi-mode fibre.
Using the SY-MMU Range of Matrix Switchers
Connecting the Outputs and Inputs
Connect the input sources to their respective connectors in the INPUT groups and connect the display
devices to their respective connectors in the OUPTUT groups. Connect local mains AC voltage supply to the
IEC connector(s) and switch it on.
If required, connect either RJ45 Ethernet cable or a RS232 cable from the control panel or control
computer to the matrix.
To ensure the safety of the operator, be sure that the earth of the AC input connector is wired to a good
local earthing point. Alternatively, connect an earth bonding strap to the earthing point on the rear of the
SY Matrix unit and a good local earth point.
SY-MMU-88A Audio Switcher
The SY-MMU-88A matrix switcher features an independent analogue audio switcher. The audio signals
routed by this switcher are completely separate to the video switcher section and can be switched
independently of the actual video selections. The front panel controls behave as follows:
The AV button changes the selections for both the audio switcher and the video switcher.
The Audio button only changes the routing of the audio switcher without affecting the video
switcher.
The Video button changes the routing of the video switcher without affecting the audio
switcher.
IEC Connectors
Note that the SY-MMU-88A Matrix Switcher has only a single IEC connector, whereas all the other Matrix
Switchers have two IEC connectors. Where there are two IEC connectors provided they should each be
connected to different ring or spur circuits such that if one ring or spur were to fail, then the other ring or
spur will continue to keep the Matrix Switcher operating.

SY-MMU-88A / 1616 / 3232 / 6464
www.sy.co.uk 8
Using the Front Panel Controls
Making Selections
AV Button
Use the following button sequence to make a video selection: input number, AV then output number or
numbers. For example to select input 2 to output 4 press the following buttons: 2 AV 4, where 2 is in the
INPUTS group and 4 is in the OUTPUTS group.
Video and Audio Buttons (SY-MMU-88A Only)
Note that the SY-MMU-88A Matrix switcher also has Video and Audio buttons, these can be used to
independently switch only the video signal or only the audio signal where these signals are provided
separately. HDMI signals have embedded audio data and therefore the HDMI audio will always switch with
the video selection. The Audio button only affects analogue audio signals connected to the terminal block
connections below the video input and output cards.
Operation is exactly the same as for the AV button.
Backspace, Comma and Enter Buttons
For the SY-MMU-1616 and SY-MMU-3232, there is both a comma button and an Enter button. The comma
button is used to separate the output channel values when a single input is being sent to multiple outputs
simultaneously in the same command.
The Backspace (←) button deletes the last key entry to allow the user to make corrections to the
command being entered at the front panel, prior to pressing the Enter button.
The Enter button on these same Matrix Switchers is always used to conclude every command entry that
require numerical input.
All and Through Buttons
The All button has two modes:
1. Send a single input to all outputs simultaneously: for example, 10 ALL will route input 10 to all
available outputs.
2. When combined with the Through Button the Matrix switcher will connect each input channel to
its corresponding output channel, thus: input 1 goes to output 1, input 2 goes to output 2, input 3
goes to output 3, and so on. The button sequence is All followed by Through.
Undo Button
The Undo button causes the Matrix Switcher to revert to the input / output configuration it had prior to
the last command sent to it.

Using IR Remote Controls
Point the IR remote control key pad at the SY-MMU Matrix Switcher and use the key pad buttons in the
same sequence as for using the front panel controls.
RS232 Control Commands
The following RS232 commands provide control of the SY-MMU range of 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.
All the punctuation characters shown in the RS232 command are part of the command and must be
included when sending the command.

required for the RS232 command.
2. When selecting multiple outputs for an input, each output must be separated by a comma ( , ) and
may appear in any order.
3. The A command is only supported by the SY-MMU-88A Matrix Switcher.
4. The B command (Select both Audio and Video) is the only video selection command that is
compatible to all matrix switchers in the SY-MMU range.
