Abstract

There is provided herein an encoded information reading terminal such as may be provided for by a bar code reading terminal for operation in a network such as a retail store network that is configured in one embodiment to automatically enter a unique association mode of operation subsequent to wirelessly receiving a radio address from one computer of a plurality of computers, e.g., a cash register address from one cash register out of a plurality of cash registers. In one embodiment a bar code reading terminal can be configured to wait for a cash register address to be wirelessly received as part of a connection request initiated from one cash register out of a plurality of cash registers. A bar code reading terminal can be configured so that when operating in a unique association mode, a bar code reading terminal transmits all decoded bar code messages output by the bar code reading terminal to an external device to the one cash register sending its cash register address.
