1. Introduction
With Korlan USB2CAN you can monitor a CAN network, write a CAN program and communicate with industrial,
medical, automotive or other CAN based device. It comes in two different versions: DB9 or OBD2.
The Korlan CANBUS USB adapter connects a CAN bus to the USB port of any device running Linux or Windows
operating system, which also supplies the power to the adapter (no power supply needed). In the downloads section
now you can find all the related drivers and software applications and even Windows 7 64-bit kernel driver, which was
added recently.
