INSTALLATION AND SETUP
You can also connect by RS232 or RS422 (see Figure 2.34), 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—set the "Network
Routing" option to "RS232 and RS422 Joined". Serial messages will reach all serial
ports.
Figure 2.34. Examples of Joined RS232 and RS422 Networks
Note 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. See 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. See Appendix C for details. 2) It is recommended that each RS232
communication cable be no more than 25 feet in length. Use high quality cables.
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. See Figure
2.35.
