BanaLogic’s Remote Testing Unit (RTU) is a small embedded computer system with an integrated 802.11 based wi-fi network interface module. The RTU measures less than 2” x 3” x 1” (W, D, H) in dimension and is designed to adapt to fit different OBD DLC location characteristics in vehicles. The embedded computer and related electronics and circuits are completely integrated into the OBD-II J1962 connector. This configuration requires almost no installation effort. In most cases vehicle owners will have no problem performing their own installation as the unit simply plugs right into the OBD DLC. There are no transponders to be mounted on the dash board, no external antenna, cabling and or other connections.
The RTU operates using power from the vehicle through the OBD diagnostic port. The system continously monitors the vehicle’s on-board computers to retrieve emission related information. The information is stored temporarily in the data logger, while it searches for a wireless communication access point. Once a wireless connection is established, the diagnostic data is transmitted to the access point.
Each data receiver module creates a a wireless communication “hotspot” of an area of about 200 meters in diameter and can communicate and process a high number of vehicles concurrently; uniquely identifying the RTU, receiving, parsing and decoding of the OBD diagnostic data and submitting the diagnostic data to a centralized vehicle inspection database.
