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....

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...

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...

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...
