Abstract
Provided is a messaging system that includes a highway message sign system. The message sign system includes a wireless cellular router having an Ethernet port and a serial port and being capable of communicating with a cellular wireless communication network. The message system also includes a camera coupled to the Ethernet port of the cellular router and a message sign. The message sign includes a message display and a message sign controller coupled to the serial port of the cellular router. The message sign controller is able to control operation of the message sign. Further provided is a method of operating message sign remote controller. The method includes receiving a request to communicate with a message sign system, executing an initialization file configured to initialize a communication port redirect, executing an initialization file configured to account for transmission latencies associated with use of the communication port redirect, generating a serial communication configured control operation of a message sign system, routing a serial communication from a message control application to the communication port redirect, converting the serial communication to an other communication protocol message receivable by a wireless cellular network, and routing the other communication to the message sign system via the wireless cellular network.
