The MG540 is a CANbus operated system.

CAN (Controller Area Network) {also referred to as CANbus} is a network used in many every-day products consisting of multiple microcontrollers that need to communicate with each other.

Reeling Drum

The reeling drum has a controller driving the data lines for the length and angle sensors. So instead of sending analog signals to the computer, the signals are converted to digital signals and routed via the CANbus to the MG540 computer. The ATB signals go directly to the MG540 computer.

Computer

The MG540 computer utilizes a CANbus circuit board with a MG500 series computer.

Husco Boom Mode Controller

This is the “Boom Latching Computer” on the CANbus, otherwise known as the Husco controller.

Optical Encoder – Extension Cylinder

The optical encoder monitors the boom extension cylinder length by means of a mini reeling drum.
