RS232 Serial Control
EXT CTRL RJ12 Pins:
RS232 control uses pin 1 for Ground (GND), and 2 Data Receive (RXD) on the EXT CTRL RJ12 jack.
The screen can be controlled via RS232 serial to perform the functions UP, DOWN, and STOP by connecting to
pins 1 and 2 on the EXT CTRL RJ12 input. This is a one-way communication, so no status is available back to the
automation controller.
Wireless 12 Volt DC Trigger:
Screens may be lowered or raised by wireless 12-volt trigger signal sent from other equipment like a projector.
The wireless 12-volt trigger operates by sending a RF signal to the screen when the projector turns on. The screen
will lower and remain lowered until the projector is turned off and the voltage drops to 0 volts. Other methods
maybe used with 12-volt trigger. However, the screen will remain lowered for use if voltage ids present on the
trigger while an attempt is made to close the screen.
Important! The projection screen still requires external AC power for operation. The 12-volt trigger connection
will NOT power the screen. Plug the AC power cord into a suitable outlet supplying 120-volt AC.
It is also important to note that you may have to change the batteries in the 12-volt trigger (CR2430 batteries) , if
the battery does not have enough voltage left in it then the 12-volt trigger will not be able to get the screen to go
back up until batteries are replaced.
