5. Connect the 24V DC PSU to the MFT-31 or it can be powered from the appropriate
HDBaseT receiver (with PoC).
6. If required, an RS232 controller may be connected to the rear of the MFT-31 to control
the MFT-31 as well as for control of the remote display device.
7. If required, an IR Eye may be connected to the rear of the MFT-31 to control the remote
display device.
Controlling the MFT-31
The MFT-31 has two illuminated buttons that indicate their respective states when there is at
least one active source present:
Using the SOURCE / AUTO Button
To toggle between MANUAL and AUTO modes, hold down the SOURCE / AUTO button for 3
seconds until the desired mode is selected.
Manual Selection Mode: Press to cycle through all three inputs.
Auto Selection Mode: Each button press will index through active inputs only. A new active
input is automatically selected; whilst de-activating the current input forces selection of the next
available input.
When there are no active inputs detected then all the input source LEDs will be off, and the
SOUCE / AUTO button will be inactive.
Using the DISPLAY ON/OFF Button
The Display ON/OFF button can be used to turn a display device on or off, either by using CEC
commands or RS232 messages.
CEC Display Power Control
The CEC commands to change the display power status (on/off) are built-in to the MFT31 by
default. Hence if the display device is CEC enabled, the ON/OFF button can switch the display
on/off through the HDMI CEC line. RS232 CEC commands to the MFT31 may be used for
controlling the display unit at any time.
RS232 Display Power Control
To use the RS232 feature of the Display On/Off button, the RS232 commands for the display
device must be programmed into the MFT31 first. Once done, the correct RS232 power
command will be sent to the display device each time the ON/OFF button is pressed.
When programming the Display On/Off RS232 commands, only use the most appropriate version
of the commands given in the following table:
