To add the projector to an existing Ethernet
network with other equipment such as
controllers and other projectors, connect
standard CAT5 Ethernet cable between your
Ethernet controller (or hub) and the
Ethernet port on the side of the projector.
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.
If you want to connect multiple projectors in a network with
RS-232 NETWORK:
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 2.21. Communicating through RS-232
: To control multiple projectors with a computer/controller having
MIXED NETWORK
an RS422 interface, first set them all to the same baud rate as your RS422 controller.
