<SERIAL/MULTI SYNC IN>/<SERIAL/MULTI SYNC OUT> terminals
The <SERIAL/MULTI SYNC IN>/<SERIAL/MULTI 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 SYNC IN> terminal and the <SERIAL/MULTI SYNC OUT> terminal, and sharing the brightness level of the
image 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.
