In the fields of automotive electronics, industrial automation, and new energy, the Controller Area Network (CAN) bus is the core nervous system connecting various intelligent nodes. With the widespread adoption of the CAN FD (CAN with Flexible Data-Rate) protocol, higher demands are placed on bus bandwidth, topology flexibility, and data management efficiency.EBYTE officially launches its revolutionary product—the EID101-B111 CAN FD Hub. It is not just an upgrade to traditional CAN repeaters/gateways but an intelligent multi-port CAN FD hub and data logger, designed to address the challenges of expansion, isolation, and data insight in complex bus systems.
Overview of EID101-B111 CAN FD Hub
The EID101-B111 is a high-performance industrial device integrating 4 independent CAN FD channels, data storage, and intelligent routing functions. Its design purpose is to serve as the "traffic hub" and "data black box" for complex CAN network systems.
Four Core Features
Four Independent CAN FD Channels, Flexible Topology:
Channel Isolation: Provides 4 fully electrically isolated CAN FD interfaces, each supporting independent baud rate settings (up to 5 Mbps data phase rate), effectively suppressing ground loop interference and improving system stability.
Topology Restructuring: Can segment a complex "linear" or "star" CAN network into multiple logical subnets. For example, connecting powertrain, body control, and diagnostic interfaces to different channels enables network zoning, reduces load, and enhances reliability.
Bridging and Repeating: Data forwarding rules can be configured between any two channels, enabling data bridging and repeater extension between networks with different baud rates or logical segments.
Built-in Data Logger, Ensuring Critical Information is Never Lost:
High-Capacity Storage: Onboard 8GB eMMC storage allows for long-term, high-fidelity recording of raw CAN FD messages from all channels.
Triggered Logging: Supports triggered logging based on message ID, data content, or error frames, saving only data around key events. This optimizes storage usage and facilitates fault tracing.
File Management: Logged data is stored in standard file formats (e.g., ASC/BLF) and can be exported directly via USB or network, compatible with mainstream analysis tools like CANalyzer and Vehicle Spy for offline analysis.
Intelligent Message Filtering and Routing:
Hardware-Level Filtering: Each channel supports powerful hardware filters for precise filtering based on ID ranges and masks, significantly reducing the load of invalid messages on the channel and processor.
Configurable Routing Table: Users can flexibly configure message forwarding rules between the 4 channels and between channels and the logger/network via PC software, enabling selective passthrough, protocol conversion, or data aggregation.
Rich Interaction and Debugging Interfaces:
Multiple Configuration Methods: Provides a USB-C interface for PC connection for configuration, data export, and firmware updates; supports web server for network configuration; includes a Wi-Fi module interface (optional) for wireless management.
Status Visualization: Equipped with a color LCD display showing real-time status of each channel (baud rate, load rate, error count) and storage usage.
Industrial-Grade Design: Metal housing, DIN rail mounting, wide voltage input (DC 9-36V), operating temperature -40°C to +85°C.
Typical Application Scenarios
-
Vehicle Testing and Data Acquisition: Connects to different networks (e.g., vehicle CAN, powertrain CAN, charging CAN) simultaneously during bench or real-vehicle testing, synchronously logging all bus data for performance analysis, fault diagnosis, and calibration.
-
Production Line EOL Test Systems: Serves as the core of test benches, connecting units under test (e.g., VCU, BMS) and multiple test equipment, distributing test commands, collecting response data, and automatically logging the entire process.
-
Complex Industrial Control Systems: In large machinery or energy storage systems, interconnects and isolates CAN networks of different subsystems (motor drives, BMS, I/O control) via the Hub while centrally logging operational data for predictive maintenance.
-
Gateway and Protocol Conversion: Acts as a super gateway, bridging data and adapting protocols between CAN FD and CAN 2.0A/B networks or between CAN FD networks with different rates.
-
After-Sales Diagnosis and Data Traceability: Deployed on critical equipment for long-term operational data logging. When faults occur, historical logs can be retrieved to pinpoint the bus state at the exact time of the issue.
Quick Start Guide
-
Hardware Connection: Connect the CAN networks to be monitored to the Hub's CAN1~CAN4 ports. Connect the Hub to a PC via USB-C cable and apply power.
-
Software Configuration:
-
Run the Matching EID101 Configuration Suite software; it will automatically detect the device.
-
Set the correct CAN FD baud rate (arbitration and data phase) for each CAN channel.
-
Navigate to the "Logger" settings page and select the logging mode (e.g., "Continuous" or "Triggered"). For triggered logging, define the trigger condition (e.g., data byte 0 of ID=0x100 exceeds a certain value).
-
Configure routing rules (e.g., forward messages from all channels to the internal logger).
-
Start and Export: Save the configuration and start the device. It begins operation and logs data. For analysis, export log files via the software interface or directly copy files in USB mass storage mode.
FAQ about CAN FD Hubs
Q1: How is the EID101-B111 CAN FD Hub different from a standard CAN repeater or gateway?
A1: The core difference lies in functional integration and intelligence. Standard repeaters primarily address physical layer extension and isolation; gateways focus on protocol conversion. The EID101-B111 integrates four isolated repeaters, configurable routing, hardware filtering, and a high-capacity data logger into one system-level solution. It can restructure network topology while providing deep data insight capabilities.
Q2: Can the four CAN channels be set to different baud rates?
A2: Yes. This is one of the Hub's key advantages. The CAN FD baud rate (including arbitration and data phase rates) for each channel can be configured independently without affecting others, allowing seamless connection of networks with different rate standards.
Q3: What format is the logged data in, and which analysis software is compatible?
A3: The device supports exporting to industry-standard formats like .asc (Vector ASC) and .blf (Vector Binary Logging Format). These formats can be directly opened and analyzed by almost all mainstream CAN bus analysis software, such as Vector CANalyzer/CANoe, Intrepid Vehicle Spy, and PEAK PCAN-View.
Q4: What is the purpose of the triggered logging feature?
A4: Triggered logging greatly improves efficiency by saving only "valuable" data.
Q5: How do the routing and filtering functions work?
A5: You can create flexible rules. For example:
Filtering: Set a filter on CAN1 to allow only messages with IDs in the range 0x100-0x1FF to pass through to the processing core. * Routing: Create a routing rule to forward all messages received from CAN1 (after filtering) simultaneously to the CAN2 channel and the internal logger. This enables data screening and directional distribution.
Q6: Does the device support wireless functionality?
A6: The standard model provides USB and wired Ethernet interfaces. The device has a reserved Wi-Fi module slot. Users can optionally install a specific EBYTE Wi-Fi module to enable configuration, status monitoring, and real-time data streaming via a wireless network.
