Thank you for purchasing this PRODUCT.
This PRODUCT is designed with the professional AV installers in mind. The many extensive
features assist with system integration, validation and maintenance.
Installation precautions
This product has special circuitry to protect it against moderate surges and static discharges.
However, to ensure reliable operation and long service life, it is important to take the
necessary precautions against any spikes, surges and static discharges.
Place the units away from heat sources and allow adequate ventilation.
Shielded cable and in particular cat6, cat6a or cat7 is highly recommended. As much as
possible signal cables should be routed away from any noisy sources and should avoid long
runs in close proximity to AC mains cables.

sy.uk 4V 5.0
The SY-MUHD-44 and MUHD-88 are 4x4 and 8x8 true HDMI matrix switchers respectively. They
both support HDMI1.4b up to 4K video resolution and HDCP 1.4 and HDCP2.2. It allows any source
(BluRay player, HD DVD player, satellite receiver, game station, etc.) to be shown on the any of the
displays simultaneously, no matter whether the source is HDCP compliant or not.
These matrix switchers equalize and amplify the output to ensure the HDMI signal can be
transmitted through a long cable without loss of quality.
The SY-MUHD-44 and MUHD-88 offer solutions for digital entertainment centres, HDTV retail, show
sites, data centre control, information distribution, conference room presentation, school and
corporate training environments.

Operation
Front Panel Control
The MUHD-44 and MUHD-88 front panel controls allow for the selection of the inputs to the
various outputs. First press a button on the OUTPUT row to choose the output number the
change, then press a button on the INPUT to select the input signal for the selected output.

Figure 4 - MUHD-88 IR Control
The user can control the HDMI routing of the matrix by using the supplied IR remote.
The left arrow button selects the next lowest numbered input port, and the right arrow selects
the next highest numbered input port.
The IR remote controller for the MUDH-44 also allows direct selection of the inputs for each
output.
The IR remote control for the MUHD-88 allows the user to increase or decrease all eight of the
inputs source selections simultaneously with a single button press.
The supplied IR receiver cable can be used to provide a different receiver position. Simply plug
the cable into the IR Ext socket on the rear of the matrix switcher.

EDID Setting
The matrix switcher has 12 predefined EDID settings, and 3 user programmable EDID memories.
The user EDID memories are independent to each input and can therefore be set differently for
each input. The matrix switcher can also be set to use the EDID information from any of the
output display devices.
To change the EDID setting, press and hold any INPUT button for 3 seconds and the LCD display
will show the current EDID setting for that input channel.
The EDID setting can be one of the following:
1：1080P 2CH (PCM)
2：1080P audio 5.1
3：1080P audio 7.1
4：1080P 3D 2CH (PCM)
5：1080P 3D audio 5.1
6：1080P 3D audio 7.1
7：4K30Hz 3D 2CH (PCM)
8：4K30Hz 3D audio 5.1
9：4K30Hz 3D audio 7.1
10：4K60Hz (Y420) 3D 2CH (PCM)

The first 12 EDID settings are factory set and cannot be altered. The 3 USER EDID memories can
only be programmed using RS232 commands. The EDID from any output can be programmed
either using the front panel controls as described below, or by using RS232 commands. Each
input presents its currently selected EDID setting to the HDMI source device, therefore only one
EDID setting is active at any instant, but this setting can be different for each input.
The following is an example of how to change the EDID setting for input 3:
User Action
LCD Text after User Action
Press and hold button 3 for 3 seconds.
Click button 3 to step to the next EDID setting.
(This step can be repeated until the desired EDID
setting is displayed)
Press and hold button 3 for 3 seconds to save the
setting.

When the LCD shows the following text, or similar:
Then pressing and holding button 3 for three seconds will make the matrix switcher read the
EDID from the display device connected to the selected HDMI output and save it to the input
chosen as the first step in the above table.
Please always be aware that the EDID setting of each input is independent and that, therefore,
each input may need to be programmed separately.
Display IP Information
Press and hold buttons 3 and 4 for three seconds to display the current IP settings. The screen
will change every three seconds to display the next IP setting, but will always begin with the
current IP address of the matrix:
In order to prevent potential IP problems, most of the IP settings can only be programmed using
RS232 commands.
Changing the DHCP Setting
Press and hold buttons 1 and 3 for three seconds to change the DHCP setting. The LCD will show
the new DHCP setting:
or
Setting the Cascading Mode
When the cascading mode is enabled, the matrix will not read the EDID or Hot Plug Status from
any display device and will always output the HDMI signal. This mode should only be enabled if
the installation is experiencing some HDMI problems and enabling this mode solves the
problem. If the problems persist when the cascading mode is enabled, then there may be a
handshaking issue between the matrix and the display device.
The cascade mode is enabled when the LCD shows the following:

RS232 Commands
The SY-MUHD-44 and SY-MUHD-88 4K switcher can also be controlled using RS232 commands.
The following table lists all the available commands that can be used to control or configure
these 4K switchers.
The baud rate settings are: 57600, 8 data bits, no parity, 1 stop bit and no handshaking.
In all the commands given in the tables below, all the indicated characters are required, but the
 character represents the carriage-return character, 0x0d.
Any command that is shown with brackets must include those brackets.
A number of commands given in the following tables, output a large amount of ASCII encoded
information that can be too much for systems where there is only a small amount of available
memory as this data can be several kilobytes long. The >@RH and >@RSTA commands should
be avoided whenever possible as the Read Status Commands can provide the same information
as >@RSTA, but only for a specific feature, and without any additional information to process
that is not relevant to the status of the requested feature. The >@RH command merely provides
a list of all the available commands with a brief description included for each one.
In the majority of cases, the command response is simply the command received by the 4K
Switcher with the first character changed to < (0x3c). Thus, the command to output 1 to show
input 2:
>@WSVO[1]I[2]will reply with <@WSVO[1]I[2]
