Chapter 2 • Configuration and Installation

1.The System 4xi must be configured internally for the projector/monitor to be used. This is done at the factory when the unit is ordered, and a label is placed on the rear panel to identify the configuration. However, there may be times when the configuration must be changed for a different application.

2.Place, or mount, each piece of equipment in the location where it will be used.

3. Connect the cables and adapter between the System 4xi and the projector.

4.Connect other equipment, such as audio or various controlling devices.

5.Set up the projector, using the manual(s) provided by the manufacturer.

_______ There are procedures in this chapter for installation of specific projectors to the

System 4xi. Use the appropriate procedure for your application.

•1 Comm Adapter (specified by the customer)

•1 CC 50' Projector Communications Extension cable

•5 Audio connectors with captive screws (audio cables not included)

•1 AC Power Cord

Removing the System 4xi Cover

If the System 4xi must be reconfigured for a different display device, it is necessary to access the Main Controller board. Also, if the main power fuse needs to be changed, you will need to access the inside of the unit. To do either of these two things, you must first remove the top cover of the System 4xi, as follows:

1.Unplug the AC power cord.

2.If rack-mounted, remove the System 4xi from the mounting rack.

3.Label the input and output cables and remove them.
