Abstract
An improved bar code symbol reading device includes a data transmission subsystem, operably coupled to a bar code reading engine, that communicates symbol character data to the communication interface of a host system over a communication link therebetween. During an interface configuration mode, the data transmission subsystem automatically cycles though at least one of a plurality of different communication interfaces (implemented by the subsystem) to test if the given communication interface corresponds to the communication interface of the host system. If this test is successful, subsequent data communication between the bar code symbol reading device and the host system is enabled over the active communication interface. In this manner, the data transmission subsystem is able to automatically configure itself for communication to the host system, and is capable of interfacing to a variety of different host devices in an automatic and error free manner with minimal human involvement.
