Features:
This module plugs directly into a standard USB port and provides a standard DB9 male output to CAN systems according to CiA (CAN in Automation) DS102-1 recommendations. It is self powered from USB. It consumes max 100mA, but normally not more than 60mA (this depends on BUS load and eventual CAN cable errors etc.). Use your own RS232 LIB/drivers (in e.g. Visual Basic, Deplhi, C++ etc.) together with the free Virtual COM port driver or use the free Direct driver DLL (see Download page for drivers). Works on Windows and Linux platforms. Easy to migrate from CAN232 to CANUSB with some small software changes. Free Windows Threaded CANUSB API DLL or use the ActiveX controller, write applications in a snap.
CAN Pin assignment:
Pin assignment according to CiA recommendations DS102-1.
The CANUSB is powered from USB port, so no need to connect external power on pin 9. Use only CAN_L (pin2), CAN_H (Pin7) and CAN_GND (pin3).
Sample Programs and Drivers:
Sample programs in C, C++, Visual Basic, Delphi, Linux etc. can be found on the download page of the CANUSB web site.
We have developed our own DLL and ActiveX control which in turn "talk" with the D2XX DLL from FTDI. This threaded DLL & ActiveX control includes Open, Close, Read, Write & Status functions and will make it quick and easy for customers to make their own applications without understanding on how to parse commands and get into how the D2XX driver work. DLL & ActiveX control is availible now. Initial tests with VB6 using this DLL shows that the CANUSB is really fast and can receive 5000+ frames per second without loosing any frames.
Looking inside the CANUSB, you find a dense 4-layer printed circuit boards with parts on both sides of the PCB. The CANUSB is firmware upgradable through the USB interface, so customers easily can update firmware when we release improved software or new functions in the software.
