Using the SY-MHDBT-44P HDMI Matrix Switcher
Connecting the Outputs and Inputs
Connect the input HDMI sources to the matrix HDMI INPUTS - connect the HDBaseT extenders to the
connectors in the OUPTUT group. Connect the power supply provided with the SY-MHDBT-44P.
To ensure safety and as a good practice, be sure to connect an earth bonding strap to the earthing point
on the rear of the SY-MHDBT-44P unit to a good local earthing point.
Using the Front Panel Controls
Use the following button sequence to make a video selection: Input number, AV, then Output number.
For example to select input 2 to output 4 press the following buttons: 2 AV 4, where 2is the INPUT
selection and 4is the selected OUTPUT.
To send a single input to all the outputs use the following button sequence:
Input number, then ALL button.

Using IR Remote Controls
Point the IR remote control key pad at the SY-MHDBT-44P 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-MHDBT-44P 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.
Any punctuation marks shown in the RS232 command are part of the command and must be included
when sending the command.

numbers required for the RS232 command.
2. When selecting multiple outputs each output must be separated by a comma and may appear
in any order.
3. The EDIDUpgrade command must have a binary image file containing the new EDID information
within 10 seconds of the command being issued.

Sending RS232 Data from a PC to a HDBaseT Receiver
The command to send data from a PC given in the above table is used as follows:
RS232 command: /+x/y:******.
Value x represents the output channel to send the RS232 data to. This can be either 1 to 4 for each of the
four outputs respectively, or 5 to transmit the data through all four outputs simultaneously.
Value y ranges from 1 to 7 inclusive and represents the transmission baud rate as detailed below:
Y value
baud rate
1
2400
2
4800
3
9600
4
19200
5
38400
6
57600
7
115200
In the above command ****** represents the data to be transmitted to the remote location(s). This data
can be up to 48 bytes in length, full stop characters are allowed within the data values, but the last full
stop must be present to indicate the end of the command.
Using the EDID Upgrade Command
The EDID upgrade command requires careful consideration because there is a ten second time out period
within which the new EDID binary image must be sent to the SY-MHDBT-44P. If no data arrives within that
ten second window, then the command is automatically aborted.
The binary image must be a valid EDID data block in multiples of 128 bytes.
