Transfer Speeds

The Volvo Controller area network (CAN) has two transfer speeds.

• HS CAN (high speed) has a transfer rate of 500 kbit/s.
• MS CAN (Middle speed) has a transfer rate of 125 kbit/s.

1 kbit/s = 1000 bits per second (1 byte = 8 bits).

For serial communication (Volcano Lite) between a control module and a slave control module the transfer rate is 9.6 kbit/s.
