Greer CompanyMG540 Display
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.

MG540 Display The MG540 display is actually a mini computer
comparable to a PDA. It runs on Windows CE and uses a compact flash memory card to store the system chip information.
It uses a large color LCD panel that uses a white background for better viewing. It has 3 levels of brightness.
