S400 Series Post #4: Next Gen Hardware & Software
Smarter Controls. Faster Diagnostics. More Productive Paving.
Today’s paving environment demands more than horsepower and hydraulics. Contractors need machine intelligence that improves uptime, simplifies diagnostics, and keeps crews productive. That’s exactly what the upgraded G&Z S400 was engineered to deliver.
At the center of the system is G&Z’s modular software architecture — designed for performance today and scalability for future technologies.
• Plug-and-play capability for future integration
�• Simplified software updates and system expansion�
• Modular hardware design that improves serviceability and reduces spare parts inventory
The upgraded S400 also incorporates advanced diagnostic and telematics capabilities through the EGON Operator Control System:
• Wireless global cellular connectivity
�• Remote Wi-Fi access for software updates, diagnostics, and parameter adjustments
• Bluetooth-ready local connectivity
�• CAN bridging for communication between the paver and attachments�• Real-time monitoring of machine status, fault codes, and maintenance intervals
For contractors and fleet managers, that means faster diagnostics, reduced service trips, and more informed maintenance planning.
Operator productivity was also a major focus of the hardware redesign. The improved BP-2 wireless Belly Pack control console and display features:
• Improved switch and k**b spacing with enhanced tactile feel�
• Touch-activated LED illuminated controls for low-light paving
�• Integrated fault clearing, work light control, and engine idle selection
�• “Night Mode” display for reduced eye strain during night operation
�• Magnetic docking and charging station
�• Ruggedized console construction with lockable Fold-and-Stow enclosure
The updated user interface also streamlines machine automation by accelerating track movement during machine transitions and automatically skipping completed or unnecessary steps.
Improved waterproof remote ground control corner boxes with illuminated controls further enhance operator convenience and visibility during low-light operation. Combined with the S400’s simplified hydraulic architecture and reduced component count, the result is a machine that’s easier to operate, easier to maintain, and more productive on the jobsite. The S400’s new upgrades are about reducing downtime, improving operator efficiency, and lowering operating cost over the life of the machine.
The new S400 isn’t just smarter…it’s engineered to help contractors pave more profitably.
