2.5 | System Components

A Level COMMAND system consists of multiple hardware and software components working together to provide terrain positioning, implement guidance, and automatic control functionality.

System configuration may vary depending on:

  • machine profile,
  • hydraulic architecture,
  • installed hardware,
  • and enabled automatic control functions.

Required Components

The following components are required for normal Level COMMAND operation.

COMMAND ECU

The COMMAND ECU provides machine interface control, hydraulic output control, sensor monitoring, and automatic control management.

The ECU receives target information from Level COMMAND and controls hydraulic or vehicle interfaces during automatic control operation.

The COMMAND ECU also manages:

  • automatic control engagement,
  • positioning validation,
  • sensor monitoring,
  • and hydraulic fault protection.

GNSS Receiver System

A compatible RTK-capable GNSS receiver system is required for terrain positioning and automatic control operation.

GNSS positioning information is used to determine:

  • machine location,
  • implement elevation,
  • vehicle heading,
  • and terrain position relative to the active design surface.

Automatic control operation requires stable RTK-quality positioning.

Operator Display Device

Level COMMAND operates on a compatible display device used for:

  • terrain visualisation,
  • project management,
  • automatic control monitoring,
  • diagnostics,
  • and operator interaction.

The display device communicates with the COMMAND ECU during operation to exchange positioning, control, and machine information.

Hydraulic Control Hardware

Compatible hydraulic control hardware is required to allow automatic implement movement during automatic control operation.

Hydraulic control configuration may vary depending on:

  • machine profile,
  • hydraulic architecture,
  • and supported vehicle integration methods.

Optional Components

Depending on machine configuration and enabled features, additional components may be installed to provide expanded functionality.

Cross-Slope Sensors

Cross-Slope-capable machine configurations require compatible implement roll-angle feedback sensors.

Supported Cross-Slope feedback sources currently include:

  • T3RRA TARS IMU systems,
  • and compatible StarFire internal roll-angle sensors.

Additional Operator Controls

Optional operator control devices may be installed depending on machine configuration and operational requirements.

These may include:

  • external Arm/Engage switches,
  • joystick controls,
  • and auxiliary operator input devices.

Vehicle Integration Interfaces

Some machine configurations may support additional vehicle integration hardware for communication with supported OEM machine systems.

Depending on machine compatibility, this may include:

  • CANBUS interfaces,
  • J1939 vehicle communication,
  • and supported OEM hydraulic integration systems.

Component Compatibility

Supported system components may vary depending on:

  • installed COMMAND hardware,
  • machine compatibility,
  • software licensing,
  • and supported machine profiles.

Refer to applicable COMMAND installation and commissioning documentation for machine-specific compatibility and installation requirements.
