CAN Bus/Event
The RT-3020M also employs a balanced (differential) 2-
wire
CAN Bus technology interface, ISO11898 -24V
compliant. The CAN interface uses an asynchronous
transmission scheme employing serial binary
interchange and is widely used in the automotive
industry. The data rate is defined as 250K
bps
maximum with Termination resistors used at each end
of the cable. This port/connector is shared with the
Even t Input.
