• One “Control Panel Processor” (within the control panel itself) oversees the large User
Display, the small MLE displays, and also translates button presses into serial protocol
that is sent to the frame — indicating which buttons have been selected. The processor
also tracks which functions have been selected in which MLEs, and at a very high level,
provides the frame with specific information that removes the need for the frame to
know precisely what the panel looks like.
For example, the panel does not say that button 32 has been pressed, rather, it says that
there is a request to select a circle wipe on MLE 2, pattern generator 2. The frame
processes the command and sets the new state of the MLE and pattern generator. In the
case of a knob or the Positioner, the panel alerts the frame that the control is increasing
or decreasing in value. Disk storage and recall information is also handled by the panel
processor, but the data ends up in the frame.
All boards in the Synergy Q/MD frame also contain a TI MSP430 microcontroller to manage
upgrades, system booting, and other housekeeping functions.
A Note About CPU Architecture
Virtually all of the lookup tables and all of the bits that are used to configure the hardware and map the
crosspoints are set
every field . The system is in effect performing a complete memory recall operation
every single field, always guaranteeing that the control panel is set properly. In terms of the
architecture, there is no difference between a
requested memory recall operation and the way that the
switcher updates the panel normally — every field.
In addition to increasing system reliability, this functionality also allows you to return to the exact
state of the panel, should a power failure occur.
