INSTALLATION AND SETUP
SHORTCUT METHOD:
You can also issue software protocol settings through the keypad. These software commands
will be lost when the keypad is either unplugged or when a battery is removed - the keypad will
revert back to the hard-wired jumper settings (see above) until you enter the software com-
mands again.
Press = Protocol “A”
Press = Protocol “B”
NOTE: If you change any keypad to a new protocol and the projector stops responding, the
projector may be set to a conflicting protocol. Use the projector’s built-in keypad to access the
Serial Setup menu. Under “Front IR” or “Back IR” or “Wired Keypad”, select the protocol that
matches the new protocol of the keypad at hand. The projector should now respond
properly.
Converting a Keypad
If desired, you can convert an IR remote keypad into a wired remote keypad and vice versa.
TO CHANGE FROM INFRARED TO WIRED:
Remove battery compartment cover from back of keypad.
Remove batteries.
Wait 1-2 minutes.
Plug the keypad cable (available separately) into the empty battery com-
partment. Make sure that the battery cover is notched smoothly to accom-
modate the cable.
Set keypad protocol as desired, using “wired” jumper settings.
Replace battery compartment cover.
Plug into the 3-pin XLR port at the rear panel of the projector.
TO CHANGE FROM WIRED TO INFRARED:
Unplug the keypad from the projector.
Open the keypad back and unplug the keypad cable.
Wait 1-2 minutes.
Install batteries (see Section 4.3).
