ZeroNoise Clear Voice Systems

ZeroNoise Clear Voice Systems are designed to improve rally communication through the integration of wired and wireless technologies.

The product range includes:

• WW System
• Fearless System
• Pit-Link System
• OffRoad System
• Fury

Crystal-clear audio ensures that critical notes and instructions are heard and understood, even in high-noise vehicle environments. Bluetooth connectivity also keeps the crew in contact with support staff and team management.

Depending on the selected system, all or a subset of the following features may be available:

• Wired and Wireless Technology (WW): Provides reliable, delay-free communication and seamless switching between wired and wireless modes.
• Advanced Noise Cancelling (All systems): Filters unwanted background noise to ensure clear communication.
• Automatic Connection Switching (WW): Automatically switches between wired and wireless modes during stages and road sections.
• Keyboard and Touchscreen Display (All systems): Displays system information, including battery level and connection status, and allows audio parameter adjustment.
• Helmet and Headset Compatibility: Supports Bell MAG-10 Rally Carbon WW and HP10 Rally WW helmets, ZeroNoise WW headsets, and devices equipped with a female Nexus connector.
• Driver and Co-Driver Wireless Freedom (WW): Maintains communication when users leave the vehicle, for example during a tire change.
• Customizable Sound Settings (All systems): Allows audio tuning for different stage conditions and personal preferences.
• Bluetooth Team Communication (All except OffRoad): Supports communication with service crews and team management.
• Stage Mode (All except Pit-Link): Restricts communication to the driver and co-driver during competitive stages.
• In-Car Camera Audio Output (All except OffRoad): Supports direct recording of driver and co-driver communication.
• External Radio Audio Input/Output (All except OffRoad): Supports direct communication through an external radio system.

The repository contains two CAN database files:

Both databases use:

• Standard 11-bit CAN identifiers
• 8-byte CAN payloads
• Intel/little-endian signal encoding
• Signal definitions aligned with the corresponding C header files

Version v1_08 is aligned with the header definitions for CAN IDs, DLC, signal start bits, signal lengths, factors, offsets, valid ranges, signal names, and reserved-bit allocation.

ZN_CAN_WW_v1_08.dbc describes the CAN communication interface of the ZeroNoise WW system.

The WW-specific message 0x40F includes:

• Driver and co-driver connection status
• Driver and co-driver headset connection status
• Driver and co-driver battery level
• Charging status for supported wireless devices
• Autocharge status

ZN_CAN_FEARLESS_v1_08.dbc describes the CAN communication interface of the ZeroNoise Fearless system.

The Fearless database does not include the WW-specific message 0x40F.

The following updates are included in both databases where applicable:

• STS_External_PTT assigned to bit 38 of message 0x410
• STS_CAN_PTT assigned to bit 39 of message 0x410
• Noise and voice filter ranges set from 1 to 5
• Signal names aligned with the corresponding C header definitions
• Associated VAL_ enumerations and CM_ comments updated
• Reserved fields maintained only in unused payload areas
• No signal overlaps

The DBC files are standard raw ASCII databases and can be imported into:

• Vector CANdb++
• Vector CANoe
• Vector CANalyzer
• PEAK PCAN-Explorer
• BusMaster
• SavvyCAN
• Other DBC-compatible tools

The databases can also be used for embedded code generation, diagnostics, automated testing, and CAN monitoring.
