4.7.2.3 Multiple CADWall (Showroom Installation)
This chapter will describe the Stereo Connections for e.g. a setup with 2 Triple-Channel CADWalls in the same
room e.g. a Showroom. Both CADWalls have there own IG. We assume only the IG used by CADWall 1 has an
Synchronous Output Range.
It is possible to let CADWall 1 work synchronous with IG 1. The projectors of CADWall 2, that are in asyn-
chronous mode, will then display the image at the frequency of IG 1.
Respect the following 2 rules when setting up such a configuration:
1. The IR Emitter must be connected to a projector running in Synchronous Mode.
2. All projectors connected to the synchronous IG must be set in Synchronous Mode.
3. All other projectors (CadWall2, CadWall3, ...) must be set in Forced Asynchronous Mode.
How to connect the Stereo Signals in a Multiple CADWall Configuration (Showroom Installation)?
1. The Stereo Sync Signal coming from both IG’s is connected to the Stereo In Mini DIN Inputs of both Multi-Channel Configurations.
(image 4-9)
Note: On some IG’s, the Stereo Sync is already present in the Vertical Sync Signal.
2. Connect a ’Phased L/R Signal’ BNC Connector of the first projector to a ’Phased L/R Signal’ BNC Connector of the second
projector.
3. Continue until the Phased L/R Signal is connected ’Looped Through’ to all the projectors of both Multi-Channel Configurations.
4. Connect the ’IR Emitters to a free ’Phased L/R Signal’ BNC Connector on a projector that is set to Synchronous Mode.
All projectors will run on a common Stereo Sync (Phased L/R) Signal.
All Stereo IR Emitters in the room will work in sync.
