Abstract
A management system includes a daisy chain arrangement for serial transfer of dock status data from one module to another of a group of monitoring modules and to a master control box, each module being located at a dock of a multi-dock facility. The master control box periodically receives dock status data from one or more groups of modules, determines whether any change of status has occurred and transmits data to a central processing unit.
