5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the overlapping blends
disappears or changes to very light gray. For the shared edge, use the same Blend Width setting on each
projector. If the “best blend” appears to be between two settings, choose the wider setting for both
projectors.
6. Check Blend. If the blended region appears too dark or light in relation to the rest of the image:
a. Increase Blend Midpoint in both projectors to “lighten” the overall blend, decrease to “darken” the
overall blend.
b. Adjust Blend Shape in both projectors to fine-tune change the amount of mid-gray intensity (as
opposed to black/white) in the blend.
7. Repeat steps 1 to 6 with remaining projectors / overlaps.
8. Check completed display wall with the desired external signal.
9. Adjust mechanical alignment if necessary to maintain perfect pixel-on-pixel alignment over time.
10. In applications where you are projecting only white or light images, the
Blend Width may be slightly
higher. Set according to how much overlap you have between images. Use the following as a guide
(examples show overlapping width only—values for overlapping height will differ):
• If side overlap is 15% , set Blend Width to 24
• If side overlap is 20% , set Blend Width to 32
• If side overlap is 25% , set Blend Width to 40
• If side overlap is 30% , set Blend Width to 48
4.16 Remote Control of the Projector
As an alternative to using a keypad, most projector functions can be controlled remotely, typically at a
controller such as a PC, via simple bi-directional ASCII messaging on an Ethernet or serial communication
link.
Setting up a Remote Controller

To control projector functions remotely via Ethernet and your own controller, either open an Ethernet socket
between your controller and the valid projector address, or connect a serial link between your controller and the
RS-422 ports or the RS-232 In port. Connect all ports, if desired.
For complete information, including a list of valid ASCII messages and how to structure them for use, obtain
the current
Christie Serial Communications document.
4.17 Error Conditions
Occasionally the projector will encounter an error condition that can interrupt normal operation. This can be
caused by a simple invalid keypad entry, an input signal error (most common) or a system error. How users are
notified of error conditions is set in the
Menu Preferences menu:
• To see error messages displayed on-screen, select the “
Screen
” option
• To be notified via a serial communication only, select the “
RS-232
” option.
• To receive both types of notifications, select “
All
”.
