3-6-2-5. 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 DCS-1000B 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 DCS-1000B only needs one wire,
CAN-High or CAN-Low for decoding.
Panel operation 1. Connect the bus signal (
CAN Input)
to one of
the channel inputs. Connect the ground
potential of the bus to the probe’s ground clip.
