<SERIAL IN>/<SERIAL OUT> terminal
The <SERIAL IN>/<SERIAL OUT> terminals of the projector conform with RS-232C so that the projector can be
connected to and controlled from a computer.
A combined screen with a balanced contrast can be displayed by linking multiple projectors using the <SERIAL
IN> terminal and the <SERIAL OUT> terminal, and sharing the brightness level of the video signal input to each
projector when structuring a multi-display screen by combining the projected images from multiple projectors. It is
also possible to synchronize the shutter operation of the specified projector to other projectors.
For the connection method of the projectors when using the contrast synchronization function or the shutter
synchronization function, refer to “Connecting example when using the contrast synchronization function/shutter
synchronization function” (

To control the projector with standby mode when connecting utilizing the DIGITAL LINK compatible device, set the [PROJECTOR SETUP]
menu
→
[STANDBY MODE] to [NORMAL].
When [STANDBY MODE] is set to [ECO], the projector cannot be control during standby.
