On applications where a Sd-25-w/DMX, Sd-50/8, Sd-50/40, or ‘Smart’ Brick Show Control System is mounted on a vehicle, wiring control signals to them is usually impractical. The InfraRed Trigger link can be used to request and play specific shows and messages through the serial port without any wires. It can be used on trains, dark rides, monorails, trams, subways, rollercoasters, and a variety of mass transit systems. When used on vehicles which are used on different routes, the appropriate messages will be selected and played automatically.

Our Sd-25-w/DMX, Sd-50/8, Sd-50/40 and ‘Smart’ Brick Brains have a mode to support the IR Link. This mode filters the data from the IR link before it actually starts a show or plays a sound to avoid false triggers.

In applications where all you need to do is trigger messages sequentially (not randomly) the IR Link would be overkill. Standard rollover switches, pressure mats or optical sensors should be used: Our Ir-Passive is a passive infrared motion detector. The Ir-Thru and Ir-Retro are through beam and retroreflective infrared beam-break sensors.
