<p>An electronic sign includes at least one display, at least one processor controlling the display, and at least one computer readable storage medium accessible to the processor and storing a preprogrammed network address of a control server. The medium is programmed with instructions to cause the processor to automatically, upon initial energization at an advertising site having plural wireless routers all on a common subnet, connect to a wireless router at the advertising site to join the common subnet. The instructions also cause the processor to access the control server using the network address of the server after joining the common subnet. Additionally, the instructions cause the processor to receive, from the control server, configuration information useful in configuring the sign for operation so that the electronic sign, after mechanical installation, does not need to be physically accessed by a technician to further configure the sign for operation.</p> |
