Remote Panel Switch Settings
The remote control panel has a cutout on the back to allow access
to three switches. The first switch determines the panel ID
number; the second switch determines the sources, destinations,
and levels the panel will control; and the third switch determines
whether the panel is in normal operating mode or one of four
diagnostic modes. The source, destination, and level offset of the
panel must match the switcher it controls. Diagnostic modes are
described in the Performer
Service Manual.
Panel ID #
As many as 32 communicating devices may be placed along a
single RS485 bus. Each device must have a unique ID number
(address). Segments 4 through 8 of the first switch are each
assigned a value; that value is added into the address total when
the segment is in the ON position. See the illustration below.
Source Offset
Segments 1, 2, and 3 of the middle switch determine Source Offset.
The segments operate in binary fashion (1 most significant; 3 least)
to select source offsets from 0 to 7. When a source offset of 0 is
selected the panel will control sources numbered from 1 through
10. If a source offset of 1 is selected, the panel controls sources 11
through 20. When a source offset of 2 is selected, the panel controls
sources 21 through 30. This sequence continues through a source
offset of 7 and controlled sources from 71 through 80.

In the example, switches 4 and 8 are
ON. Since #4 has a value of 16 and
#8 a value of 1, the panel ID # is 17
(16 + 1 = 17).
