3in1 Ultra CAN-II CAN Analyzer Supports for USBCAN + PCAN/Kvaser + Dual Mode

When working with CAN bus systems, one of the most annoying problems is having to prepare different CAN interfaces for different software. Some applications expect PCAN hardware, others work with Kvaser devices, while many CAN testing programs are designed around ZLG USB-CAN interfaces.

The Ultra-CAN-II CAN Analyzer is designed to simplify this setup. It combines multiple CAN interface cores into one device and supports PCAN, Kvaser and ZLG USB-CAN compatible modes.

For automotive diagnostics, new energy vehicle development, CAN bus testing, ECU communication and software development, this type of multi-protocol USB-to-CAN interface can reduce the need to keep several different CAN adapters on the workbench.

What Is Ultra-CAN-II CAN Analyzer?

Ultra-CAN-II is a dual-core USB-to-CAN interface designed for CAN bus communication, analysis, testing and development.

The device integrates cores for PCAN/Kvaser and ZLG USB-CAN. It can work with the corresponding original drivers and can also support third-party applications developed around these interfaces.

Three Main Functions in One CAN Interface

Instead of using separate hardware for different CAN software environments, Ultra-CAN-II combines three functions:

• ZLG USB-CAN compatibility
• PCAN compatibility
• Kvaser compatibility

The CAN0 channel can switch between PCAN and Kvaser modes using a physical button, while CAN1 works as the second channel of the ZLG USB-CAN interface.

Designed for Automotive and New Energy CAN Applications

CAN communication is widely used in modern vehicles, including conventional vehicles and new energy vehicles.

Ultra-CAN-II can be used for applications such as:

• CAN bus monitoring
• ECU communication testing
• CAN message analysis
• Automotive electronic module testing
• New energy vehicle CAN diagnostics
• CAN bus simulation
• Software development and debugging
• CAN communication research

Ultra-CAN-II USB-CAN Kernel Features

The USB-CAN kernel is designed to provide compatibility with ZLG USBCAN-II hardware environments.

ZLG USBCAN-II Compatibility

Ultra-CAN-II is fully compatible with ZLG USBCAN-II (I+/IIA) functionality.

This allows compatible software to communicate with the device using the expected USB-CAN environment.

CAN0 and CAN1 Dual Channels

The USB-CAN function provides two CAN channels:

• CAN0: Main CAN channel
• CAN1: Secondary CAN channel

CAN0 uses the DB9 interface and supports the device's multiple operating modes, while CAN1 is dedicated to ZLG USB-CAN functionality.

CAN 2.0A and CAN 2.0B Support

Ultra-CAN-II supports both common CAN frame formats:

CAN 2.0A

Supports 11-bit standard identifiers.

CAN 2.0B

Supports 29-bit extended identifiers.

This makes the interface suitable for a broad range of CAN bus applications.

Wide CAN Baud Rate Range

The supported baud rate range is:

40 Kbps to 1 Mbps

This range covers many common CAN bus communication speeds used in automotive and industrial applications.

PCAN and Kvaser Kernel Features

The second core provides compatibility with PCAN and Kvaser environments.

One-Button Mode Switching

One practical feature is the physical mode switch.

Users can switch between PCAN and Kvaser modes with one button without unplugging and reconnecting the USB cable.

This can make testing more convenient when working with software that requires different CAN interface environments.

PCAN Compatibility

The device is designed to be compatible with PCAN-USB IPEH-002022 environments and related software applications.

This allows compatible PCAN software to communicate with the interface through its PCAN mode.

Kvaser Compatibility

Ultra-CAN-II also supports the Kvaser Leaf Light V2 environment.

This gives users another hardware-compatible option without requiring a separate physical Kvaser interface for supported applications.

Timestamp Resolution

The PCAN/Kvaser kernel provides an approximate timestamp resolution of:

42 μs

Accurate timing information can be useful when analyzing CAN messages, examining bus traffic and debugging communication sequences.

Dual-Channel CAN Architecture

One of the main design features of Ultra-CAN-II is its dual-channel architecture.

CAN0: Main CAN Channel

CAN0 is the primary channel and uses a DB9 interface.

It supports:

• ZLG USB-CAN mode
• PCAN mode
• Kvaser mode
• CAN 2.0A
• CAN 2.0B
• 40 Kbps–1 Mbps baud rates

The PCAN/Kvaser operating mode can be changed using the physical button.

CAN1: Secondary CAN Channel

CAN1 functions as the second channel of the ZLG USBCAN-II architecture.

Unlike CAN0, the CAN1 channel supports USBCAN functionality only.

This configuration provides additional flexibility for CAN testing and communication tasks.

Dual-Core and Triple-Function Design

The Ultra-CAN-II is not simply a conventional USB-to-CAN adapter. Its internal architecture is built around two CAN cores.

Device Manager Recognition

Depending on the operating mode, the device can be recognized as compatible hardware for:

• PCAN-USB
• Kvaser
• ZLG USB-CAN

This allows compatible applications to communicate with the corresponding virtual hardware environment.

Simultaneous CAN Communication

The two cores can communicate with CAN simultaneously.

In supported configurations, users can enable both cores or use only one core depending on their testing requirements.

Run Multiple CAN Software Applications

Another useful capability is the possibility of using different CAN software environments at the same time.

For example, PCAN-View and CANtest can be opened simultaneously and communicate with CAN through the corresponding cores.

This can be useful during CAN bus development, message testing and bus simulation.

CAN Bus Simulation and Testing

The internal cores can also communicate with each other through CAN.

This provides a convenient environment for sending and receiving CAN frames during testing.

For developers, this can be useful when creating communication tests without constantly changing between multiple physical interfaces.

CrossFire Automatic Software Recognition

Ultra-CAN-II also supports CrossFire technology.

Automatic CAN Analyzer Identification

CrossFire can automatically identify the type of supported CAN analyzer software being used.

Instead of manually changing the hardware mode every time, the system can automatically select the corresponding operating mode.

Simplified Operation

This feature is particularly useful when working with several CAN applications during the same project.

The basic workflow becomes simpler:

1. Connect Ultra-CAN-II to the computer.
2. Launch compatible CAN software.
3. Allow CrossFire to identify the software environment.
4. Start CAN communication and analysis.

The goal is to reduce unnecessary hardware switching and make the device easier to use.

CAN Bus and Electrical Specifications

Ultra-CAN-II supports common CAN bus standards used in automotive and industrial environments.

Ultra-CAN-II Technical Specifications

Ultra-CAN-II vs. Multiple Separate CAN Interfaces

A traditional CAN development setup may require different hardware interfaces for different software ecosystems.

For example, one application may require PCAN-compatible hardware, another may expect Kvaser, while a third application may work with ZLG USB-CAN.

Ultra-CAN-II combines these supported environments into one device.

One Device for Multiple Software Environments

The main idea is simple: instead of preparing multiple USB-CAN adapters, users can use one Ultra-CAN-II interface for supported PCAN, Kvaser and ZLG applications.

Easier Hardware Switching

The physical button allows CAN0 to switch between PCAN and Kvaser modes without disconnecting the USB cable.

CrossFire further helps simplify the process by automatically identifying supported CAN analyzer software.
