CONNECTING TO A PC: If you are connecting the Ethernet port directly to a PC (rather
than a network or hub), make sure to use a crossover Ethernet cable. Keep in mind
that an Ethernet link cannot be used for downloading a software upgrade to the
projector—use RS232.
Figure 2.7.
Upon connection to an Ethernet network, the projector’s factory default IP address of
0.0.0.0.0 will automatically enable the DHCP function (if available on the network) to
assign a new IP address that is valid and unique for that network. Or, if there is no
DHCP function available on the network (or if a specific static IP address for the
projector is preferred or required), you can set the address in the Ethernet Settings
menu or via an ASCII serial command.
Regardless of how it is assigned, once a projector has a valid and unique address it
will respond to commands sent to this address. To determine the projector’s current IP
address, consult the Status or Communications menus.
Refer to Section 3 for further information about setting up and using a projector
connected via Ethernet.
RS-232 NETWORK: If you want to connect multiple projectors in a network with serial
communication, connect the controlling source to the RS232 IN connector of the first
projector in the network. Then take another serial communication cable and connect
one end to the RS232 OUT connector and the other end to the RS232 IN connector of
the next projector. Continue this pattern of connection with all projectors in the
network. The last projector in the network will only have a connection to the RS232
IN connector. See Figure 2.8.
