Title: Communication device and method for electronic price label systems

Abstract: A communication device and method for electronic price label (EPL) systems which use EPL components. The device includes a microcontroller, a first EPL circuit enabled by the microcontroller which sends a first signal to an EPL computer in response to a first polling signal from the EPL computer indicating that data from the microcontroller is ready for transmission, a number of second EPL circuits which store the data from the microcontroller and which send the data to the EPL computer in response to a second polling signal from the EPL computer, a third EPL circuit which receives a second signal from the EPL computer acknowledging receipt by the EPL computer of the data, and which signals the microcontroller of the receipt of the data, a keypad coupled to the microcontroller for recording the data from an operator, and a display for displaying the data as it is recorded and for displaying an indication of the receipt of the data.
