8 Inch Touchscreen Multifunction Display ME Track Guide III

Typical Faults:
The touch panel does not respond to commands
Presence of dead zones on the screen that are no longer responsive to touch
Black screen despite the unit being powered
Dim or absent backlight
Freezes on startup with a static screen

The OE code 31302713X31408 identifies the onboard terminal of the Müller-Elektronik family (part of the PTX-Trimble Group) TRACK-Guide III, a professional 8" display used in parallel guidance systems and precision agriculture.
It is a standalone cab monitor, i.e., it can be installed on tractors and working machines equipped with an ISOBUS network, designed to manage assisted or automatic guidance and the execution of field tasks.

It is a high-value electronic component, supplied either as a single terminal or as part of complete kits with GNSS receiver and dedicated cabling.

Technical features

• Parallel guidance device with functions of a universal ISOBUS terminal and Task Controller.
• 8" (approx. 203 mm) color TFT display.
• Screen resolution 800 × 600 pixels.
• Capacitive touchscreen with robust front glass suitable for cab use.
• Typical operating voltage between 10 V and 32 V DC.
• Compatible with 12 V and 24 V electrical systems common in agricultural machinery.
• Designed to operate across a wide ambient temperature range.
• Protection rating suitable for use in dusty environments and dirty working conditions.
• Weight of about 1 kg, suitable for mounting on articulated brackets or dedicated arms.
• Multipin connectors for power and data communication.
• CAN / ISOBUS interface for connection to tractor ECUs and implements.
• USB port for backups, firmware updates and exchange of field data.
• Camera input for implement or rear-area view.
• Connection to an external GNSS receiver via dedicated cabling.
• Preinstalled parallel guidance applications on the terminal.

DIPA can intervene to overhaul these modules thanks to its experience and expertise.

Functions

• Parallel guidance with A-B lines, A+ patterns, contours and advanced modes for irregular fields.
• Clear display of deviation from the ideal path with graphical and numeric indicators.
• Management of headland maneuvers to reduce overlaps and missed coverage.
• Display of the work map in 2D or 3D.
• Coloring of worked areas, overlaps and unworked zones.
• Display of field boundaries and excluded or non-workable areas.
• ISOBUS terminal functions for control of compatible implements.
• Automatic control of boom sections in sprayers and fertilizer spreaders.
• Management of seeders, tank implements and other equipment with ISOBUS ECUs.
• Integration with Task Controller for planning and management of tasks.
• Import and export of jobs, maps and agronomic data via USB.
• Use of an external multi-constellation GNSS receiver paired with the terminal.
• Connection of a camera to improve visibility of the implement or rear area.
• Quick switching between guidance screens, maps, camera and settings menus.

Common faults

• The touch panel does not respond to inputs.
• Presence of dead zones on the screen no longer sensitive to touch.
• Black screen despite the unit being powered.
• Dim or absent backlighting.
• Boot freezes with a stuck screen.

Final conclusions

The Müller / PTX Trimble TRACK-Guide III display, OE code 31302713X31408, represents a central element in precision agriculture systems, as it integrates parallel guidance, ISOBUS implement management and job documentation in a single device.
Its modular and upgradable architecture allows functions and performance to be adapted over time to fleet needs without replacing the hardware.
