An induction subsystem for a conveyor sortation system and method of inducting articles includes providing a plurality of tandem conveying surfaces. The method can be performed by expressing the pixelaudio clock rate and the link rate with four parameters, A, B, C, and D based upon a master frequency 23. The PLC processes the input signals and transmits such signals in pulse width modulated format to the electronic control module, which processes the signals and directs corresponding output signals to control operation of the equipment. The system for processing material may further include a printer configured to print labels for application to work pieces processed by the system.
