About Multiplexing

CAN Multiplexing offers increased performance, added flexibility, reduced development time, and lower lifetime vehicle ownership cost. 

 Benefits of multiplexing:

• Reduce wiring complexity and cost
• Easily add production or aftermarket options while keeping base unit cost low
• Quickly introduce new vehicle features with minimal hardware modifications
• Locate I/O modules close to the source for simple distributed intelligent control
• Simplify vehicle troubleshooting 

Multiplexing allows you to distribute electronic control judiciously to various quadrants or input/output concentration areas on your vehicle, coordinating electronic sensors and operator inputs with output devices and actuators using computer logic.

Even though electronic controls tend to be simpler than hydraulic or mechanical linkage controls, the number of wires involved can quickly add up. Multiplexing allows control of multiple functions through a single pair of wires, eliminating the need for complex wiring harnesses.

HED is experienced at designing control systems that make use of multiplexing, and can work with or design systems communicating in SAE J1939, CANopen, DeviceNet, ISO 11783 (ISOBUS), or customer-specific communications protocols to name just a few.

Engine Control
Communications with Engine Control Modules (ECM), enables task-based control of engine operating/idle speed. In addition, you can monitor engine conditions (overheating, transmission status, etc) from the operator station and automatically control vehicle load conditions to prevent engine stall.

Multi-Station Control
Multiplexing simplifies control of vehicle or tool operation from multiple points on the vehicle: from the operator’s cab, from a station near the tool, or even remotely (off-vehicle) through a wired or wireless connection.

Self-diagnosis and reporting
Multiplexing simplifies the hardware / software interface and makes it easier to locate problems and alert operators. In addition to built-in diagnostic capabilities, HED multiplexing can check the entire network from a single module, using Windows-based software.

The bottom line
HED multiplexing, the CANLink^® system, is designed for survivability under extreme and hostile environments. Multiplexing means lower costs, fewer wires to break, faster speed-to-market and simplified troubleshooting in the field. Plus, the HED CANLink^® products offer maximum protection from high EMI/RFI exposure, extreme vibration and temperatures, dirt, dust, moisture and hard equipment wash-downs.
