The SY-MS42-18G is an 18G HDMI video switcher with 4 HDMI inputs and 2 scaling HDMI
outputs. Each input and output supports up to 4K60 444 HDMI 18G video. The outputs can be
individually scaled for 1080p or HDBaseT compatibility. De-embedded audio as analogue L+R
and optical TosLink is available for both outputs. The SY-MS42-18G can automatically control
the display device using RS232, CEC or IR when the last input signal is lost, or when the first
video input is detected. This switcher can be controlled from the front panel, RS232, IR, or LAN.

Two 18G HDMI 2.0 video outputs supporting up to 4K60 444 resolution
Both outputs can be individually scaled for 4K  1080p or HDBaseT mode
Four methods of control: Front panel, RS232, IR and LAN
Automatic RS232, CEC and IR control of the display device power state
Two sets of de-embedded audio analogue and TosLink outputs, for both outputs
ARC decoding to the TosLink audio outputs only.
Test Pattern mode for testing output signal integrity to the display

Power LED and Standby Mode
The Power LED provides the following indications:
Colour
Description
Blue
The SY-MS42-18G is active and fully controllable
Red
The SY-MS42-18G is in standby mode, this state can be changed by using
RS232 or LAN commands, or from the WebGUI interface
Auto LED and Button
The green AUTO LED for both outputs A and B is lit when that channel has its Auto Detection
mode active. Auto Detection mode will detect any new HDMI signals and immediate switch to
the input. If the currently selected input is removed then the switcher will switch to the next
available input, or remain on the current input if there are no active HDMI input signals.
The change the Auto Detection mode, press and hold the button for that channel for 3 seconds
until the Auto LED changes state.
Selecting Inputs
Manual Selection of the inputs is done by briefly pressing the push button repeatedly for that
channel until the desired input is selected. Manual selection is always possible, irrespective of
the Auto LED state. Selected inputs that have no signal will be indicated by a flashing LED.

Sending Display RS232 Commands
The SY-MS42-18G is capable of sending RS232 commands direct to the HDMI display using RS232
ports A and B. For this command, the leading zeros are required.
Set Command:
s rs232 (port) (format) (baudrate) (databit)
(parity) (stopbit) (cmdterminating) [cmddata]!
Response
example:
Format: ASCII
Baudrate: 9600
Databit: 8bit
Parity: none
Stopbit: 1bit
Terminator: cr
Data: xb 00 90
Where:
(port) is the HDMI output port:
01 = RS232 A
02 = RS232 B
(format) is the command representation format:
00 = ASCII 01 = Hexadecimal

V1.0 15 sy.uk
(buadrate) is the transmission baudrate:
00 = 4800, 01 = 9600, 02 = 19200,
03 = 38400, 04 = 57600 05 = 115200
(databit) is the number of data bits:
00 = 7 bits 01 = 8 bits
(parity) is the partiy mode:
00 = none 01 = odd 02 = even
(stopbit) is the number of stop bits:
00 = 1 stop bit 01 = two stop bits
(cmdterminating) is the command termination mode:
00 = none 01 = CR only
02 = LF only 03 = CR+LF
[cmddata] the command data, without the specifed terminating
values, to send. This must match with the value given in the (format)
specifier and the actual command must be enclosed with the square
brackets. See the examples given below.
Command Examples:
Both the following examples use port settings of 9600, no parity, 8 bits and 1 stop bit.
To set an LG display on RS232-A to HDMI 1, in ASCII with a CR command terminator:
s rs232 01 00 01 01 00 00 01 [xb 00 90]!

Using the Built-In Web Interface
The SY-MS42-18G has a built-in web interface to provide a means of controlling or configuring
various settings within the switcher. There are seven pages available, each of which will be
outlined in detail in the following sections.
The seven pages are:
1. Status – Displays information about the firmware and IP settings
2. Switch – Control the video routing and enabling the test pattern mode
3. Input – Displays information about the input signals and EDID settings
4. Output – Displays information about the output signals and scaler options
5. Network – Allows basic network setting management and login options
6. System – Serial baudrate, test pattern setting and firmware update
7. Control – Auto Power Control Settings and Commands
Note these seven pages are only accessible in Admin mode, when User mode is used only the
Status and Switch pages are available.
To access the web interface, enter the IP address of the SY-MS42-18G into the address bar of any
web browser. If the IP address is not known, use the RS232 commands given in the Network
Commands section on page 13 to discover the IP address of the switcher. After entering the IP
address the following log in screen will appear:
