The MSG-2191 is a signal generator designed for generating simulation signal of VICS' Infrared Beacon and Radio-wave Beacon; it is used for testing Infrared/Radio-wave Beacon receivers. This unit is operated from a PC through USB interface by using the attached application software. Also, users can input their Infrared Beacon data and Radio-wave Beacon data to this unit from PC. A special designed antenna for transmitting/recovering beacon is attached as standard. Note: The application software is not capable of creating and editing data.
* In VICS (Vehicle Information and Communication System), Infrared Beacon (at Main trunk roads) and Radio-wave Beacon (at Expressways) are used for providing traffic congestion information to vehicles and collecting traveling time from vehicles.
