Control Panel Reference
Level Offset
Segments 7 and 8 of the switch determine level offset. The
segments operate in binary fashion (7 most significant; 8 least) to
select level offsets from 0 to 3. When set to 0, the remote panel
controls levels from 1 to 3. When set to 1, the level numbers are
from 2 to 4. When set to 2, the level numbers are from 3 to 5. When
set to 3, the level numbers are from 4 to 6. Since the protocol
supports only 4 levels, never set level offset to a value greater than
1 unless one of the All Levels protocol variations is selected.
The following table lists switch settings and the resulting level
offset. An “O” indicates an
open segment; a “C” indicates a closed
segment.
If two or more Performers are assigned to the same destination
and level, they cannot be independently controlled but will switch
in tandem. In this instance, only one of the Performers could be in
Master Mode; the others must be in Slave Mode to prevent their
returning a tally response which would result in a bus collision.
Multiple Performers should not be set so that their levels overlap,
e.g., one set to levels 1-3 and another to levels 2-4, unless their
destinations of control are different.
