Baud Rates
The baud rate setting determines
the speed of communication to
and from the projector on the
RS232 or RS422 links. The
maximum rate for either standard
is 115200. Set the baud rate to
match that of your controlling device, such as your PC. If you are unsure about what
baud rate to choose, refer to the documentation for the controlling device. In an
existing network of projectors, if you discover that a projector has a different baud
rate, make sure to use the pull-down list and select the correct baud rate using the
Enter key—do not just scroll this control with
communication is always 8 data bits, no parity.
Projector
Enter a three-digit number (such as "001") to assign or change a number to the
projector currently in use. If the current projector already has a number assigned, that
number will appear here (for example, "004" in Figure 3.16, above). Numerical
identity for projectors enables you to communicate with a single projector within a
multiple-projector application (see also

Not applicable for stand-alone projectors.
SEPARATE:
Select "Separate" (factory default) to keep RS232, RS422 and Ethernet
messages on their respective paths instead of being broadcast to the remaining ports.
This is useful when you have a network in which each projector is connected via both
its RS232 and RS422 serial ports (Figure 3.17
communications will stay on the path of origin only, as determined by the type of
controller. If a projector or path ever fails, you can use the other path.
