The Quazar professional system uses an Embedded PC to operate a sign. It is a scalable system that includes diagnostics which will test and report all aspects of a sign's operation. The default IP address is 192.168.1.9. However, there is a second port on the controller that is set as to a dynamic IP address. For full functionality, the end user should have the system connected to a router.
