Section 3: Operation
To replace the default "Christie logo" splash screen (or other) with one of your own, use the KoRE Librarian
to download the desired .bmp to the projector. This overwrites the current splash screen content in projector
memory.
3.8.2 System Configuration (Communication)
Settings in the
Communications
secondary menu define
and control how single or multiple projectors are can link
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 RS-232
or RS-422 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 drop-down list and select the correct baud rate using the
E
NTER key.
Do not just scroll this control with
L
EFT
or
R
IGHT
Arrow keys. Serial 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 appears here (for example, "004" in , above).
Numerical identity for projectors enables you to communicate with a single projector within a multiple-
projector application (see also
P
ROJ
key in Section 3.2 Using the Built-In Keypad or Remotes ). If you make a
mistake in assigning or changing the projector number, press
E
XIT to cancel.
Network Routing
Not applicable for stand-alone projectors or simple 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 other types of ports. This is useful when you have a network in which each
projector is connected via
both its RS-232 and RS-422 serial ports ( Figure 3-26 A)-at each projector, serial
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.
In Figure 3-26 A , failure to keep the networks separate would likely cause communication errors. In Figure 3-
26 B , where there is only one link between any two projectors (and the controller), make sure to join the
networks.
