ValueCAN 4-2
Low-Cost High Performance CAN FD - USB Interface with IP65 Aluminum Enclosure
Superior Engineering
The ValueCAN 4-2 is the next-generation, low-cost, high-performance tool for CAN FD, backward compatible with CAN 2.0. The ValueCAN 4-2 comes with all the field-tested features of the ValueCAN 3, plus much more, including software-controlled CAN termination, increased buffer size, improved USB latency performance, and standalone operating capability using a USB charger.
The ValueCAN 4-2 supports 2x CAN or CAN FD channels, has USB Type A and Type C options available, and certified drivers for Windows 7, 8, 8.1, and 10.
The ValueCAN 4-2 is fully isolated from the PC, and its isolation layer is self-powered from USB, which eliminates the need for external power for the CAN transceiver. The ValueCAN 4-2’s isolation, a feature not common on low-cost interfaces, eliminates issues with grounding or noise affecting your PC and its communications. The ValueCAN 4-2 is also electrically hardened to survive an abusive environment, including reverse battery voltage and electrical transients. To make wiring easy, the device pinout is printed clearly on the housing. The ValueCAN 4-2 is also backed by a one-year warranty.
High Performance
The ValueCAN 4-2 has been tested and verified to support two high-bandwidth CAN FD networks. This includes 100% utilization at 8 Mb/s data rates on both channels.
Turn-Key Software Support
A copy of Vehicle Spy 3 Trial Edition is included with the ValueCAN 4-2. Vehicle Spy is a powerful vehicle bus analyzer for monitoring messages and configuring baud rates. The professional user will want to upgrade to the full version of Vehicle Spy, which lets you filter traffic, decode message data, build scripts, and simulate other nodes. You can also build GUIs to control, log, view, and build graphical displays of your data.
Intrepid Security Module (ISM) for Cybersecurity
ISM runs an embedded code with the support of Coremini Standalone mode feature. ISM can be used for encryption and authentication of vehicle network data as part of the cybersecurity. Among other use cases, ISM can support
real-time processing of vehicle network data and CCP secure access.
Real Time Acceleration and Standalone Mode Enable High Speed Flashing, Gateway, and ECU simulation
The ValueCAN 4-2 can load real-time Function Block scripts and C code created with Vehicle Spy Professional, which execute in real time at microsecond resolution. Scripts can be controlled and monitored with a PC or operate standalone.
High-Level Protocol Support
The ValueCAN 4-2 is compatible with J1939, OBD2 on CAN, Keyword Protocol over CAN, UDS diagnostics, CCP/ XCP, DeviceNet and CANOpen. Cables are available for J1939 and diagnostics on CAN. Hardware-implemented ISO15765 allows super fast CAN FD ECU flashing.
CAN Bus Termination Test
The ValueCAN 4-2 can be used with Vehicle Spy to check the termination of an attached CAN network. This is done by generating a CAN error frame and measuring how much time the bus takes to recover from the error, with microsecond-level resolution.
Software Support: Create Your Application Using the Included Intrepid DLL API, J2534 API, or RP1210 API
For those who wish to write their own applications, the ValueCAN 4 includes a DLL and helpful examples for Python, Visual C++, C++ Builder, LabWindows CVI, LabVIEW, Java, MATLAB, Delphi, Excel, and Visual Basic. For more information on the DLL, please see the neoVI DLL documentation (the ValueCAN4 uses the neoVI DLL).
