1. Control Box

Description

The bridge between the software running on the tablet and the tractor. With the RTK module (that can be purchased seperately), centimetre-precise positioning with tilt compensation 10 times per second can be achieved. With the IMU, also responsible for tilt compensation, the slightest twist/slip of the tractor can be detected and corrected instantly.

Communicates with the tablet via ethernet cable.

In addition, convenience switches, sensors and other peripherals can be connected via this interface.

A program running on the tractor calculates the desired steering axis angle 10 times per second and monitors 20 times per second in attempt of adjusting it.

The front wheel (or the waist joint) can be moved in the following ways:

• DC motor with gears or by friction drive
• Keya with a brain motor
• Factory and/or aftermarket solenoid steering hydraulics control block
• Danfoss PVES control block (usually factory fitted in JD)

For the safety release, one of the following solutions can be used:

• measuring the engine overload
  • for DC motor with 20A current meter
  • for Keya motor from the current consumption message on the CAN bus
• for hydraulics
  • by setting the number of changes if
    • equipped with encoder / pulse transmitter
    • equipped with pressure switch
  • by selecting the % cut-off pressure
    • for pressure sensors 0-5 V and 4-20 mA
    • for analog type encoders

With differential input for compatibility with factory angle sensor. With 5V short-circuit protected output for own angle sensor.

Can be used with a maximum fuse of 10A.

RTK module with antenna

Equipped with feet (spike line), configured for AgOpenGPS. With 15 cm diameter galvanized antenna backing plate, which is highly recommended for good quality reception.
If ordered along with a control box, we will install it in the box and test it together.

In case of usage as a line guide or measuring stick, we also add a box and USB cable.

A proven product from Ardusimple. Includes the F9P RTK GPS module and the black antenna for centimetre-precise positioning and navigation.
