Station Communications Cable — CANbus Network Design
The EEC4 system utilizes a CANbus digital communications system to link the components in the con-
trol system — Control Processor (CP) and Control Heads (CH). There are various ways in which the
Station Communications cable can be connected depending on the application.
The Single Station Layout (see illustration on the next page) is straight-forward and easy to under-
stand. A single Station Communications cable connects the CP and the CH — cables are available in
20, 30, 40, or 60 foot lengths. A terminating resistor is plugged into the other CANbus connector at both
the CP and CH.
