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

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
