Module Control
The primary method for control and monitoring of the PA Modules is by the serial CAN
(Controller Area Network) Bus. It is used for control, status and monitoring of all PA
Module parameters and for the reporting of Module faults. As a backup to this serial
control network, each PA Module has dedicated hardware control lines for functions
such as On, Off, Restart and RF Mute.
