Using the MS44-18G
Manual Selection
To change the displayed image for any output, press the appropriate Select button on
the front panel, to select the required input. The numbered LED on the front panel will
light to indicate the current input selection for that output.
IR Remote Control
The IR remote control provided with the switcher may also be used to select the
images, by first pressing an output number or the ALL button in the Output group (1-4),
and then an input number in the Input group (1-4).
The PTP button on the IR remote will make the following selections: 1 → 1, 2 → 2,
3 → 3 and 4 → 4.
Press X button to cancel operation and power button for standby mode. All other

Connecting the MS44-18G
RS232 and IP Commands
All RS232 commands are sent with the following settings:
115200 baud, 8 bits, no parity and 1 stop bit.
All commands are stated in ASCII notation and must be used as given in the following
tables. The spaces shown in the commands are required and the command must only
contain the values given in the Description column.

Commands can also be sent to the LAN CTL port using the following default IP
settings:
Host IP Address: 192.168.1.168
Subnet Mask: 255.255.255.0
Router IP Address: 192.168.1.1

AA is 02 for 4K2K@60 (YC420)
AA is 03 for 4K2K@60 (YC444)
For the EDID setting command, BB is a bit mask (7,6,5,4,3,2,1,0) that allows multiple
options to be set at the same time. For the colour depth settings, the values for bits 4 to
6 may be used in any combination to enable all desired colour depth modes. Bit 1 to
select the number of audio channel, but only one bit must be set for these audio bits.
Bit 7 (HDR mode) and bit 0 (3D mode) can be used independently of all the other bits.

When sending the EDID setting command, the binary bits in the above table will need
to be converted to their hexadecimal form as sent as two ASCII characters, for
example:
To set the EDID for input 1 to 4K2K@60 (YC444), HDR, 48 bit colour, 7.1ch audio &
3D the binary bit pattern from the above table would be: 11001001, which is C9 in
hexadecimal.
Also, XX = 05 for Input 1 and AA = 03 for 4K2K@60 (YC444).
The completed EDID command is: @W 05 03 C9 #
RS232 Control Software
The SY-MS44-18G can also be controlled via RS232 using PC software. The PC must
be connected to the matrix switcher to allow the PC software to function correctly. Up on
starting the software select the PC serial port from the drop-down list and click on the
Connect button in the COM Setting panel.

From TV1 to Copy From TV4 options are selected, the option buttons below that
selection box are not available.
After making any changes, click the relevant Apply button to store them in the matrix switcher.
The Read button for each input group reads the data from the current EDID mode of the
respective input on the matrix switcher.
