Electronic Controls Complex machines require complex controls. Control systems that use traditional hydraulic conduit and mechanical linkages can quickly get out-of-hand. Electronics offer a way to simplify control while actually offering greater precision for specific tasks. Benefits include: Simplicity Instead of routing hydraulic conduit to the operator station and then to the tool, hydraulics only need to go from the power source to the tool. This allows for a smaller, easier-to-use operator station and cost savings, especially when the operator is located some distance from the tool. Reliability...

Multiplexing 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. 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. Systems with 2, 22, or more nodes can dramatically reduce...

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. More and easier to read information is available...

Vehicle Applications CAN Multiplexing Offers Increased Performance, Added Flexibility, Reduced Development Time, and Lower Lifetime Vehicle Ownership Cost Reduce wiring complexity and cost Easily add production or aftermarket options while keeping base unit cost low Quickly introduce new vehicle features with little or no hardware modifications Locate I/O modules close to the source Simplify vehicle troubleshooting Fire Aerial Ladder Application The number of wires exiting a fire truck cab can number in the hundreds without the use of CAN multiplexing technology. The reduction in vehicle wiring...

Vehicle Applications Road Building Machine Road building vehicles such as recyclers and skid-steer loaders are often offered with a multitude of variations or attachments. Multiplexing systems allow the pre-wiring for these options for addition of control module hardware only as needed to implement the options. The software for additional options can be included on the base unit and options or attachments can be automatically recognized when added on the production line or by the dealer or end user. The use of identification pins in the wiring harness can also allow identical control modules...

Windows-based programming expands the capabilities of CANLink™ CANLink™ modules can be programmed at HED and shipped ready for your single application, or they may be programmed by your own design team. This allows designers to give vehicles different performance characteristics for different applications without changing the basic production hardware components. The benefits include simplified design, reduced inventory and the ability to quickly deliver customer-specific products. Do-It-Yourself Windows-Based Software Programming Tool CANLink™ Composer This easy-to-use software requires no programming...
