Figure 2.15. Connecting RS-232 between multiple projectors
Plug the projector's line cord into the AC receptacle accessible from the rear of the
projector in the bottom left corner of the Dual Lamp Module (DLM). Then plug the
3-pronged end of the line cord into a grounded AC outlet. Input voltage to D100U
and D100UF models must be capable of 100-240 VAC. Use the proper power
source and the rated line cord provided (North America only). See Section 5,
Specifications for all power requirements.
Do not attempt operation if the AC supply and cord are
not within the specified voltage and power range.
Caution: Once the projector is powered down, wait approximately 10 minutes to
allow the lamps to cool sufficiently before unplugging the projector from the AC
outlet.
At manufacture every keypad is assigned "A" as its default protocol, which is simply
a collection of settings that determine how the keypad operates. Once assigned, this
protocol remains in effect until it is changed—that is, the keypad will operate as it
currently does until you change its protocol.
Protocols are most useful for multiple-projector applications. For example, you might
want to change a keypad protocol if you are working with two projectors and two
remote keypads in the same room and need to control each projector independently
(Figure 2.16). When Keypad A has a different protocol than Keypad B, each keypad
communicates only with the projector having a matching protocol. Or, if you have a
network of two or more projectors connected together via RS-232 serial ports, you
may want only certain projectors to respond to a wired keypad, thus you can use
different protocols to limit responses.
NOTE: Matching the protocol on the projector to that of a keypad is done through a
setting in the Communications menu. See menu descriptions for further information
on how to change the projector's infrared sensor (rear and front) protocol.
A protocol for either type of remote keypad — IR or wired — can be changed. A
remote can be changed, manually by "hard-wiring" new jumper settings inside the
keypad so that they remain in effect until you change the hard wiring. Note that a
hard-wired protocol can be temporarily overridden by the software protocol change,
