01 / CONFIGURATION DIRECTIONS

Select a configuration from the application boundaries

These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.

01

Single bus pair

A compact shielded or unshielded pair for a primary CAN channel.

02

Redundant bus

Two controlled pairs combined for dual-channel or fault-tolerant system architecture.

03

Hybrid CAN construction

CAN pairs combined with power, discretes or other signals in one cable while managing coupling.

Match a solution direction to the link target

Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.
