Section 2: Installation and Setup
NOTES:
1)
You can only connect up to a maximum of 32 projectors.
2)
Figure 2-37
depicts a typical input/output
configuration, however, since RS-422 ports are bi-directional, other various combinations are possible.
You can also connect by RS-232 or RS-422 (see
Figure 2-38
), in which case either type of serial
communication must also reach the other type of port. You must enable this joining of network ports in the
Communications
menu by selecting the "
Network Routing
" option to "
RS232 and RS422 joined
" option.
This enables all Serial messages to reach all serial ports.

It should be noted that Communication parameters, such as baud rate, must be set to match the particular
controlling device
before
connecting as a network. Refer to the documentation that came with your controlling
device in order to determine the proper baud rate. Refer to
Section 3.8 Adjusting System Parameters and
Advanced Controls
if you need help changing the projector baud rate.
NOTES: 1)
To avoid damage, connect only properly wired serial communication cables. Refer to
Appendix A:
Serial Communication Cables
for details.
2)
It is recommended that each RS-232 communication cable
be no more than 25 feet in length. Use high quality cables.
2.7.2 Ethernet Networks
Ethernet Network Setup
To add one or more projectors to an Ethernet network, use standard CAT5 cable to connect each projector's
Ethernet port to a hub belonging to the network. A controller or PC must also be connected to the hub.
