ABSTRACT:
A fully automatic bar code symbol reading system is provided having at least one portable bar code symbol reading device and an associated base unit positioned within the data transmission range of the bar code reader range without a physical wiring connection between the bar code reader and the base unit. After each successful reading of a bar code symbol, the bar code reading device automatically produces symbol character data representative of the bar code symbol, synthesizes a group of data packets each containing the symbol character data, and then transmits the synthesized group of data packets to the base unit. Upon the successful receipt of one of the transmitted data packets and the recovery of symbol character data therefrom, the base unit generates an acoustic acknowledgement signal that is perceptible to the user of the bar code symbol reading device and indicates that the transmitted symbol character data has been successfully received. The base unit includes data format conversion circuitry that converts the symbol character data into the same format produced by a computer keyboard, and an interface circuit that interfaces the output port of the base unit with the keyboard input port of the host device.
