How to use the GPIO interface on Barco MDSC displays

Below is the connection diagram for a GPIO (General Purpose Input/Output) interface used with the MDSC-

1119 and MDSC-2124 displays.

Requirements:

• 3.5mm (1/8”) mono and stereo (TRS) connector

• One or two buttons/pedals and/or switches of your choice

• Three wires and housing of desired length

Assembly:

• Connect a wire to switch/pedal/button A and the A part of the TRS connector shown above

• Connect a wire to switch/pedal/button B and the B part of the TRS connector shown above

• Connect ground wire from the TRS connector and switch/pedal/button

• Closing the switch or depressing a pedal/button will now complete the circuit and generate a

response when the GPIO interface is enabled in the OSD

Instructions for use:

• Insert your TRS plug with assembled switch/pedal/button into the corresponding connector socket

next to the power input on the MDSC display.

• It is possible to display text, change inputs and/or toggle PiP order using the GPIO interface (See

MDSC-1119-2124 User Manual for more details).

• Setup of the GPIO interface can be done in the Setup menu of the OSD or using the RS232 ASCII

command interface (See ASCII command manual on CD for more details).

• You can select how the MDSC display’s GPIO is triggered. A Pulse triggers on only the first changing

edge. A Level triggers on both the rising and falling edge. E.g., if you are changing inputs and have

the Pulse selected, pressing and releasing a pedal will cause the input to change once. But if you

have selected Level, depressing and releasing the pedal will cause the input to change two times as

though it received two separate GPIO commands.

• GPIO 1 and 2 can be operated independently from one another; you can select any type of interface

or trigger type for each or use only one at a time.
