4. Use the following three color slide bars, Black Red Level, Black Green Level and Black Blue
Level, so the black hue of each projector matches.
5. You can choose which of the next four options, Top, Bottom, Left, Right, to use depending on
which edge of the projector you are working with has been edge blended. The blend width
can be adjusted to line up properly but by default it corresponds to the edge blending setting
determined for that edge.
6. The brightness and black hues of the blended region can be adjusted in more detail in case
fine-tuning is needed (may be only necessary for blending a 2 x 2 projector display because
of blending differs for the sides and center).
noTes: 1) The menu options vary depending on the Edge Blending parameters. 2) You may
need to re-adjust the black level hues following the overlap adjustments on each blended edge.
3) When adjusting six or more projectors, you need to ensure that the hue and brightness of each
target area is matched at closely as possible.
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 an Ethernet network. Using a PC interface can also
prove to be useful in instances where extreme warping is applied and the menu items become
illegible and hard to navigate.
VIa asCII MessagIng
— Connect a serial link between your controller and the 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
Serial
Communications
document available in Appendix B.
VIa Web InTeRfaCe
— Connect your PC to the projector’s Ethernet port. In your web browser
(
Internet Explorer
, for example), enter the IP address of the projector you wish to control. This will
start a password-protected application — enter the factory default “
ccm7
” login and password
to open the program. If the projector is powered up, you can access assorted menu options and
slide bars.
Repeat for remaining networked projectors as desired. Keep in mind that multiple units can
be controlled from one PC, but each unit will be in its own interface (web browser) at the PC.
Likewise, you can make up to five separate web locations to a single projector.
The default login provides access to security settings, where you can define other users with
the same or fewer rights. Use “unlimited” rights for most applications. For all logins, the Service
menu is still protected with its own password.
