Step 3: Set the Jumpers
Set the jumpers to match one of the protocols shown in Figure 2.53. Use tweezers or
needle-nose pliers to remove and replace each jumper as necessary.
•
J1 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol.
•
J2 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol.
•
J3 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol.
•
J4 jumper: For IR use, always set between pins 1 and 2 (see A-G below).
Figure 2.53. Locating and Setting the Jumpers
NOTE: Protocols B-G are not supported in v1.1 software. Use "A" or "Wired" only.
Step 4
Replace battery compartment cover. Plug into projector (wired keypad only) and test.
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 Communications submenu. Under "Front IR" or "Back
IR", select the protocol that matches the new protocol of the keypad at hand. The
projector should now respond properly.
SHORTCUT METHOD:
Unlike earlier Christie projectors and keypads, there is no shortcut method for
changing a keypad's protocol through a special sequence of keystrokes. You must
change the internal jumper settings.
'
If desired, you can convert an IR remote keypad into a wired remote keypad and vice
versa. Set the jumpers as shown in Figure 2.53, and add or delete the cable and
batteries as required. The cable with appropriate connector is supplied with the
projection head.
TO CHANGE FROM INFRARED TO WIRED:
•
Remove battery compartment cover from back of keypad.
•
Remove batteries.
•
Wait 1-2 minutes.
