CAN Serial Bus Interface
The controller area network (CAN) bus is a half duplex 2 wire
synchronous serial interface. The CAN bus is a multi-master
communication system that relies on arbitration to solve contention
issues. The MSO-2000E supports both CAN 2.0A and 2.0B. The
CAN bus uses two wires, CAN-High and CAN-Low. These wires
are voltage inverted, and as such, the MSO-2000E/2000EA only
needs one wire, CAN-High or CAN-Low for decoding.
