Picture ID
[Picture ID] is used to change the settings of a specific set (display) using a single IR receiver for multi-vision.
Communication is possible between a Projector with an IR receiver and other Projectors using RS-232C cables. Each
Projector is identified by a Set ID. Setting [Picture ID] allows you to only use the remote control with Projectors with a
[Set ID] that matches the [Picture ID].
1 Assign [Set ID] to the installed Projectors as shown below:

2 Press the (red) button on the remote control.
3 Make sure that the Picture ID you set is identical to the [Set ID] of the Projector you wish to control.
• A set with a [Set ID] that is different from the [Picture ID] cannot be controlled by IR signals.
NOTE
• If [Picture ID] has been set to 2, only the upper right Projector, which has a [Set ID] of 2, can be controlled by IR
signals.
• If you press the (green) button on your remote control, the [Picture ID] for all Projectors are turned
off. If you then press any button on the remote control, all Projectors can be controlled by IR signals regardless of
their [Set ID]’s.
