MDO-2000E series User Manual

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 MDO-2000E series 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 MDO-2000E Series only
needs one wire, CAN-High or CAN-Low for decoding.
Panel operation

channels.
