Enter a three-digit number (such as "001") to assign or change a number to the
projector currently in use–if the current projector already has a number assigned, that
number will appear here. Numerical
identity for projectors is required whenever
you want to communicate with a single
projector within a multiple-projector
application (see
3.3, Using the Keypad). If you make a
mistake in assigning or changing the
projector number, press
For complete information about controlling
multiple projectors, see Section 3.9.

NOTES: 1) Requires double serial links—RS-232 and RS-422—between all
projectors in a network. 2) Set each projector's Broadcast Key OFF. 3) Keypads
cannot broadcast in a split network—use controller(s) instead. 4) Do not use a split
network when downloading new projector software to a network.
Enter a Split Network checkmark if you have a network in which each projector is
connected via both its RS-232 and RS-422 serial ports (Figure 3.18A). At each
projector, serial communications will then remain on either its RS-232 or RS-422
path (depending on the controller) rather than being broadcast to all 3 remaining
serial ports. Should a projector or path ever fail, the other path will be available as a
back-up. The Split Network feature is unnecessary when only a single serial link is
connected between any two projectors (Figure 3.18B), and will cause communication
errors if these single links vary from RS-232 to RS-422 anywhere in the network.
Likewise, if you have two serial links connected between any two projectors, failure
to use the Split Network checkbox can also cause a communication error.
