Network Operation
Up to 1000 projectors can be linked together in a chain with the ‘OUT’ port on one connected to the
‘IN’ port on the next. A controller connected to the ‘IN’ port on the first projector can control them
all, either by broadcasting messages which have no address and are thus seen by all projectors, or
by directing messages to specific projector addresses.
To work with a specific projector in a group, the projectors must first be assigned a unique I.D.—
either a projector number or an Ethernet IP address. Insert the number of the target projector
between the starting ‘(’ and the three-character ASCII code.
Message for Specific Projector
Each projector compares the message address with its own address and, if matching, responds and
processes the message. If the address does not match, the message is passed on until it reaches
the intended projector.
Although messages without an address are always broadcast, you can also broadcast by including
the reply destination address 65535. This ensures that replies go to a specific controller address
rather than being broadcast. The projector will also include its address.
Message for Projector from a Specific Controller
If you have more than one controller on a network, ensure to include both a source address and a
destination address. With a single controller on the network, its address is never required. Place the
source address between the destination address and three-character code, including a space before
and after as shown.
NOTE:
Replies from a projector do not contain an address unless the request
message includes both a destination address and a source address—i.e., a reply to a request having
only a destination address will not have any source address.
