CLO function of one projector
Linked CLO, used by multiple projectors
If the linked CLO function is in the OFF position, the lamp of each projector will follow its own life cycle curve (dotted lines). When in
the ON position and linked as described below, all projectors will use the preprogrammed CLO value as long as no projector in the
chain is using its maximum lamp power already. Once one projector is on its maximum lamp power (projector with the lowest light
output) all other projectors will follow from now on the life cycle curve of this projector. That means that light output will be constant
as long as no projector has reached its maximum lamp power. From then on, the light output of all projector will decrease (full line).

Linking via the RS232 in/out
The constant light output of projectors in a chain (maximum 12 projectors) can be set to the same value by linking the projectors via
the RS232 connector.
To the RS232in of the first projector, a terminator must be connected (Z3498823). The out of the first must be connected to the in
of the next projector, etc.
All projectors must have a different projector address between 1 and 12.
All must have the same baud rate and RS mode.
The constant light outp
ut setting of one projector must be in the master position. All others must be in the slave position.
