Two Different Serial "Splits"
There are two different split serial network configurations possible (refer to Figure 2-42 ). Set up according to
one of the following options as to which one best suits your application needs:
A. Split Network with One Controller . If you have a single controller and want a back-up serial link, connect
one controller standard (e.g., RS-232) to one physical end of the network and the other controller standard
(e.g., RS-422) at the other physical end of the network. Make sure the
Separate
option is selected for the
"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
RS-232/RS-422 adapter.
B. Split Network with Two Controllers . If you have two controllers (one RS-232 and one RS-422) 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 RS-232 and RS-422 ports as shown. Make sure the
Separate
option is
selected for the "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.
For either configuration below, make sure to segregate the networks from one another by selecting the
"
Separate
" option for "Network Routing" in the
Communications
menu. Refer to Figure 2-41 .
NOTE:
When connecting RS-422 to a projector, use either the identical rear ports (6-pin XLR) or the 9-pin
"RS422 IN" port on the side Input panel
.
