CAN BUS Interface
OpenTracker features a standard CAN Bus interface on the main connector. The CAN bus needs a
termination resistor (typical 120 Ohm) which is not on-board (but usually present on the vehicle bus).
The transceiver used is SN65HVD230. For more info and electrical specifications refer to the component
datasheet at: http://www.ti.com/product/sn65hvd230
