OPERATION
to safely change its own protocol:
1. Select the
A
or
B
option. This will ensure that once your keypad is manually changed
(see Step 2), it will still be recognized by the projector.
2. Unplug the keypad and change the protocol in the keypad as desired. Do this either
by entering the short-cut software command or by hard-wiring the keypad as
described in 2.10,
Keypad Protocols and Conversion
.
3. Plug the keypad back into the projector. Return to the
Communications
menu and
select the new protocol you have just set up in the wired keypad.
TURNING OFF THE WIRED KEYPAD
: If you want to disable the wired keypad entirely,
you cannot use it to select the
OFF
option. This safeguard prevents you from accidentally dis-
abling the wired keypad during use. Instead, use either the built-in keypad or the IR remote
keypad to select
OFF
. The projector will no longer respond to the wired keypad.
Broadcast Keys
Enter a checkmark if you want keypad commands sent to one projector to be relayed to all pro-
jectors in a network. Note the key will temporarily “override” the effect of a broadcast
setting and allow you to control a specific projector when necessary.
Projector
Enter a three-digit number (such as “001”) to assign or change a number to the projector cur-
rently 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 communi-
cate with a single projector within a multiple-projector
application (see key description in 3.8,
Using the
Keypad
). If you make a mistake in assigning or changing
the projector number, press to cancel.
For complete information about controlling multiple pro-
jectors, see
Section 3.8
.
Preferences
Use
Preferences
checkboxes and pull-down lists to alter how the projector responds to com-
mands and displays its parameters. Refer to the “
Using Slidebars and Other Controls
” subsec-
tion if you need help. Changes made to the
Preferences
menu will be saved when you exit the
menu.
