Control Panel Modules Overview
Control Panel Modules Overview
The control panel modules do everything under the control of the
microprocessors in the switcher frame.
■ M/E 1 functions are under the control of the M/E 1 Processor
■ M/E 2 Functions are under the control of the M/E 2 Processor
■ All other functions are under the control of the HOS Processor
Each of the three signals has its transmitter and receiver on each end and
their own wires in the control panel cable.
There are three types of modules in the control panels.
■ Switch Modules
■ Panel Microprocessor (PUP) Modules
■ Control Panel CPU Module
The Switch Modules have all of the operator panel controls.
The PUPs transfer signals between the Switch Modules and the Control
Panel CPU Module. There are two PUPs in the control panel. One handles
the Switch Modules in the upper portion of the control panel; the other
PUP handles the Switch Modules in the lower portion of the control panel.
The control panel CPU Module transfers signals between the PUP Modules
and the switcher frame.
The signal path is as follows:
■ A control is changed
■ The Switch Module notes the change and sends a signal to the PUP
Module
■ The PUP Module sends the signal to the control panel CPU Module
■ The Control Panel CPU Module sends the signal over the control panel
cable to the appropriate processor in the switcher frame
■ The processor sends signals to the appropriate Modules in the switcher
frame to accomplish the requested action.
■ The processor in the frame may also send a lamp on or off signal back
to the Control Panel CPU module
■ The Control Panel CPU sends the lamp data to the PUP
■ The PUP sends the lamp data to the Switch Module which lights the
lamp
