Multiplexed CAN/LIN Switching System
The CM-Series multiplexed, switching system features a Local Interconnect Network (LIN) Switch Module and a CAN/LIN Controller Module.
The switch module includes a carrier that accommodates up to three uniquely identifiable switches and rheostats (switch nodes). The carrier also features two LIN connectors, one that connects to the controller module and one that allows for daisy-chaining to other switch modules. When daisy-chained, 1 LIN Bus can accommodate up to 15 switching functions. The switch module also permits individual hardwired two-pole switches, which provide status feedback through the controller module allowing the CM-Series system to be used as a combination of LIN and directly controlled loads.
The switch nodes can be configured in various circuit functions and with standard or locking actuators, which can be laser etched on up to three locations. Illumination options include backlights and function lights, all controlled by the LIN protocol network. Each of the switch nodes can be removed or replaced simplifying service and reassignments of functions and locations.
The controller module acts as the CAN network interface to the system ECU (not provided) and the LIN switches. It accommodates up to 3 LIN buses for a total of 45 switch functions in one system.
Combined, these design and technical features make the CAN/LIN CM-Series switching system a versatile and flexible option that reduces wire harnessing and vehicle weight while providing new switching technology to meet commercial vehicle design demands.
