Upon connection to an Ethernet network, the projector’s factory default IP address of
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
submenu or via an ASCII serial command.
NOTE:
Ensure the projector is connected to the network before attempting to change
its IP address.
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
3.7, Adjusting System Parameters and Advanced Controls
for further
information about setting up and using a projector connected via Ethernet.
The GPIO Port
The General Purpose In-Out (GPIO) port enables integration of the projector within
an established control system (Figure 2.31). ASCII commands sent via the GPIO link
are stored in projector memory, where they can be triggered as a sequence of events
in the future. See
Appendix E
.

You may wish to chain two or more projectors together so that commands and
communications to and from a controller are relayed to all projectors. Choose a
hardware configuration that best suits your desired communication method.
RS232 NETWORK
: To control multiple projectors with a computer/controller having
an RS232 interface, first set all projectors to the same baud rate as the controller, then
chain the projectors together by connecting the
RS232 OUT
connector of the first
projector (already connected to the computer/controller) to the
RS232 IN
connector of
the next projector in the chain. Continue connecting projectors in this manner until
you’ve reached the last projector in the chain, so that only the last projector has an
unused
RS232 OUT
port. See Figure 2.32.
