Connecting to the Screen Trigger
If your projection system includes the electric projection screen and other 12V trigger device, you can connect these
devices to the 12V trigger to output and configure the output 12V signal settings. The projector will output 12V signals
for trigger when it’s turned on. You can use the signal to control the screen or device.
