edge (for example, if the projector's image is on left, its right edge overlaps the
adjacent image—adjust Right Blend Width). Use the same setting on the second
projector for this shared edge.
5. Re-adjust width (both projectors) until the overly bright band at the midpoint of
the overlapping blends disappears or just 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. If the blended region appears too dark or light in relation to the

rest of the image:
Increase Blend Midpoint in both projectors to "lighten" the overall blend,
decrease to "darken" the overall blend.
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 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.
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.
As an alternative to using a keypad, most projector functions can be controlled
remotely, typically at a controller such as a PC, via 1) simple bi-directional ASCII
messaging on an Ethernet or serial communication link or 2) a web interface or
"ChristieNET" on an Ethernet network.
VIA ASCII MESSAGING —
RS232 or RS422 port (recommended), or open an Ethernet socket (i.e., Telnet)
between your controller and the valid projector address. Valid ASCII codes and
messages are documented in the Christie Serial Communications document available
at the Christie website.
VIA WEB INTERFACE —
web browser (Internet Explorer, for example), enter the IP address of the projector
you wish to control. This will start a password-protected ChristieNET application—
