accidentally disabling the wired keypad during use. Use the IR remote keypad to
select
OFF. The projector will no longer respond to the wired keypad.
BROADCAST KEY - Enter a checkmark if you want keypad commands sent to one
projector to be relayed to all projectors in a network. Note the
Proj
key will
temporarily override the effect of a broadcast setting and allow you to control a
specific projector when necessary. Make sure to remove the checkmark if using the
split network feature.
PROJECTOR - 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
Proj
key description in 3.8, Using the Keypad). If you
make a mistake in assigning or changing the projector number, press
Exit
to cancel.
For complete information about controlling multiple projectors, see Using Multiple
Projectors.
SPLIT NETWORK - Enter a checkmark if you have a network in which each projector
is connected via both its RS-232 and RS-422 serial ports (Figure 3.26 - Option A).
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 3.26 – Option B), 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.
Option A – Split Network ON Option B – Split Network OFF
Figure 3.26.
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.
