3) Keypads cannot broadcast when networks are separate—use controller(s) instead.
4) Do not use a split network when downloading new projector software.
By default, communications originating from one type of serial controller—RS232
vs. RS422—stay on the corresponding network path rather than being broadcast to
the other network. This separation is sometimes known as a split network and is
indicated by a "Separate" setting for "Network Routing" in the Communications
menu (see Figure 2.37).
Figure 2.37. Keeping Networks Separate (default)
Keeping networks separate maximizes the efficiency of data transmission. In
addition, separate paths means that one path can be considered a redundant "back-
up", available if a failed projector (or controller) prevents communication via the first
path. With a split network, each projector receives and sends either type of message
depending on which controller initiates the commands—should one path fail, the
second "back-up" network path can be used. Only one network should be active at a
given time, as determined by the controller type, i.e., whether it is RS232 or RS422.
Note that the "Broadcast Key" option must be OFF.
Two Different Serial "Splits"
There are two different split serial network configurations possible (see Figure 2.38).
Set up whichever option best suits your application needs:
A.
SPLIT NETWORK WITH ONE CONTROLLER –
want a back-up serial link, connect one controller standard (e.g., RS232) to
one physical end of the network and the other controller standard (e.g.,
RS422) at the other physical end of the network. Make sure the "Separate"
option is selected for "Network Routing" in the Communications menu. If a
projector should then fail anywhere in the network, communication with the
remaining projectors can be resumed in the opposite direction using the other
standard. NOTE: This configuration requires that both standards be available
from a single controller, or that you use an RS232/RS422 adapter.
B.
SPLIT NETWORK WITH TWO CONTROLLERS –
RS232 and one RS422) and want one to be a back-up, connect each controller
to the appropriate port on the first projector in the network. Then connect
projectors together using both RS232 and RS422 ports as shown. Make sure
the "Separate" option is selected for "Network Routing" in the
Communications menu. Now, if either controller fails, you can simply switch
to the other controller and communicate via the other standard.
