Section 3 ► Operation
System Configuration
Settings in the Communications submenu define and control how single or multiple projectors
are linked with each other and with a controlling device.

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 the RS232 is 115200; for RS422 it is 19200. 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, use the pull-down
list and select the correct baud rate using the
key — do not just scroll this control with
keys. Serial communication is always eight data bits, no parity.
or
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 the menu shown above). Numerical identity for projectors enables you to
communicate with a single projector within a multiple-projector application (see also
key in
Proj
3.2, Using the Keypads). If you make a mistake in assigning or changing the projector number,
press
to cancel.
Exit
noTe: When multiple projectors are being used and you want to adjust the color and edge
blending settings for individual projectors to create one seamless image, you must assign
different numbers for each projector to allow switching back and forth between projectors while
adjustments are being made.
neTWoRK RoUTIng
noTe: Not applicable for stand-alone projectors or simple serial networks with only one type of
controller and linking.
sePaRaTe: Select "Separate" (factory default) to keep RS232, RS422 and Ethernet messages
on their respective paths instead of being broadcast to the other types of ports.
