<SERIAL/MULTI PROJECTOR SYNC IN>/<SERIAL/MULTI PROJECTOR SYNC
OUT> terminals
The <SERIAL/MULTI PROJECTOR SYNC IN>/<SERIAL/MULTI PROJECTOR SYNC 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/
MULTI PROJECTOR SYNC IN> terminal and the <SERIAL/MULTI PROJECTOR SYNC 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.
