Abstract
An electronic price label (ESL) system with communication error correction is described. In one aspect, the ESL system automatically locates an ESL after the ESL fails to respond to a message. After a number of retries to the ESL have gone unanswered, the host computer system causes all CBSs to transmit an automatic find for the ESL which is not responding. This automatic find is transmitted by all the CBSs on all timeslots. Alternatively, the find can be transmitted by one CBS or a group of CBSs in a predetermined pattern calculated to quickly find the ESL failing to respond. If the ESL responds to the automatic find command, the host computer system logs which CBS heard the response and which timeslot the ESL responded on.
