6. Reference: Connector Pinouts
This chapter contains pinout information for the vehicle interface connectors on the RAD-Star 2. For your convenience, this information is also printed on the bottom of the device. Note that the connectors for linking the RAD-Star 2 to the PC are not described here since they are industry standard (Gigabit Ethernet and USB).
