CAN Networking and
Diagnostics
A Controller Area Network, or CAN, system is a high-integrity serial data communications bus that operates at
a data rate of 250 kilobits per second for real-time control applications and uses special cables and terminators
for operation. The CAN protocol has excellent error detection and confinement capabilities, making it very
suitable and reliable for agricultural applications.
CAN systems allow products to be added to a control system at any time. Up to four product control nodes or
control channels can be connected to the Envizio Pro control system for any combination of liquid, granular,
chemical injection or spinner control applications.
The diagrams in this chapter show different hardware configurations for use with Envizio Pro series field
computers. Some diagrams show optional features which may not apply to each system. These features and
components are not required for CAN operation and optional features and cables may be ignored during a
basic installation.
NOTICE
Refer to the
Raven CANbus Network
Installation Manual
for installation information
for individual CANbus control components. Be
sure each component is properly mounted and
cables are connected prior to powering the field
computer.
