Method of automatically establishing a data communication link between an optical code reading device and a host system having a data communication interface
First Claim
1. A method of automatically establishing a data communication link between (i) an optical code reading device provided with a data transmission subsystem for implementing a plurality of different data communication interfaces, and (ii) a host system having a data communication interface, said method comprising the steps of:
- (a) operably coupling said data transmission subsystem between said optical code reading device and said host system; and
(b) during an interface configuration mode of operation, controlling said data transmission subsystem so as to automatically cycle though at least one of said plurality of different data communication interfaces so to implement a data communication interface supported by said data transmission system that corresponds to the data communication interface of said host system,wherein, for each selected data communication interface through which said data transmission subsystem cycles, said data transmission subsystem automatically performs the following operations;
(i) activates the selected data communication interface while disabling the other data communication interfaces,(ii) automatically tests the selected data communication interface so as to ascertain that the selected data communication interface corresponds to the data communication interface of said host system; and
(iii) upon, ascertaining that the tested data communication interface corresponds to the data communication interface of said host system, then automatically implementing said tested data communication interface and establishing a data communication link between said optical code reading device and said host system.

Abstract
An improved bar code symbol reading methodology/device/system includes a bar code symbol reading engine that reads bar code symbols affixed to objects proximate thereto and 3roduces symbol character data representative of such bar code symbols. A data transmission subsystem, operably coupled to the bar code reading engine, communicates such symbol character data to the communication interface of a host system over a communication link there between. The data transmission subsystem implements a plurality of different communication interfaces.
