6. Control Panels
Overview
All control panels have GPI input and output functions. Hardware control panels have 2 hardware
inputs and 2 hardware outputs; software control panels (GUIs) of course do not. All control panels,
including the GUIs, can read the two GPI inputs from the MCPM or MCE and control the two GPI
outputs in the MCPM or MCE.
All control panels can obtain the emergency bypass status from an MCPM or MCE and control the
emergency bypass relay of an MCPM or MCE.
The newer panels (CECP, CECP M1, CECP GUI, and FECP) support audio macros . There are
seven pre-defined audio macros (button functions) that create routes in the internal 16×16 audio
switching matrix of MCEs. Audio macros are disabled when the control panel is not controlling an
MCE.
Features for the Panel
The buttons and knobs not devoted to MCPM functions are for the panel itself. For instance, a
panel-lock button applies to the panel, not to any MCPM or MCE.
Panel-specific GPIO, Channel, Gang Channel, and Flip-Flop buttons control other panel-only func-
tions.
Menus
All control panels have a menu of one form or another. Operators use the menu for several pur-
poses:
• To select a main source.
• To select or change a video effect setting.
• To select an audio source.
• To perform diagnostics, updates, and status queries.
• To change the audio levels and mix.
• To select audio sources for monitoring.
• To select a channel.
“Preset Black” Transitions and TLA
All panels support preset black (PB) transitions, but only the FFCP and CFCP support the use of a
TLA for which the PB transitions have any meaning.
A “preset black” (PB) transition is one where the operator moves the lever of a TLA twice, from
one extent to the other and then back to the first extent. A “preset black” transition cuts or fade to
matte at the middle of the cycle. A PB transition guarantees that at some point in the transition, the
MCPM or MCE outputs the matte and after that point, the MCPM or MCE cannot fade back to the
original source. (After the midpoint, it can vary between matte and the preset source.)
That all panels “support” PB transitions means that when a PB transition type is selected and the
panel has no attached TLA, the MCPM or MCE performs a similar non-PB transition. For example,
if an operator chooses PB Cut, the MCPM or MCE would substitute a normal “cut” transition.
(There are no PB cross-fades. The concept is undefined.)
