Remote Aux Bus Panels
Rear Panel Switches
The rear panel includes a number of switches that control
operating modes, such as address, bus enable, delegate enable,
and test mode. These switches are set up during installation, as
described in the Installation section of the Installation & Service
manual.
Remote Aux Operation
Operation of the Remote Aux Panel is identical to operation of the
local aux panel installed in the switcher control panel.
If the switcher setup identifies a bus pair (e.g. 2A and 2B) as video
and key, selecting a source on bus 2A will also change 2B. To split
the key selection will require use of the three RU panel or two of
the one or two RU panels (one set up for each bus).
More than one Remote Aux Control Panel can attempt to control
a single aux bus. When two or more panels controlling the same
bus have source buttons pressed, the panel with the highest
address will control the source.
Joystick Override
Each panel has inputs for up to 8 external user-supplied switch
closures to enable the override. The aux bus switches to a user-
defined crosspoint selection when the switch is closed. When the
switch is released, the aux bus returns to its previous selection.
Chop
Chop mode provides continuous automatic switching between
two sources at frame rate. This function allows you to compare
two signals for system calibration.
