By default, communications originating from one type of serial controller—RS232
vs. RS422 vs. Ethernet—stay on the corresponding network path. A "Separate"
setting indicates this separation for "Network Routing" in the Communications menu.
If you are using an RS422 controller, for example, it will communicate only with the
projector to which it is connected unless you change this setting to either "RS232 and
RS422 Joined" or "All Joined".
To relay all messages to all ports—RS232, RS422, and Ethernet—set the "Network
Routing" option in the Communications menu for each projector to "All Joined".
This configuration is useful if you are using a non-RS232 controller with the RS232
linking available between these projectors. For example, you may want to use both an
RS422-compatible controller and an Ethernet-connected PC for working with a
network of projectors linked via their RS232 in/out ports.
To isolate just RS422 communications, select "RS232 and Ethernet Joined". In
Figure 2.24, only projector #3 will respond to the RS422 controller. To isolate just
Ethernet communications, select "RS232 and RS422 Joined"—only projector #1 will
respond via Ethernet.
The GPIO connector on the input panel can be used to provide a method of
interfacing a wide range of external I/O devices to the projector.
Refer to Appendix E: System Integration for complete details on pin configuration
and how to program the various pins on the connector.
