CAN Bus to PS2
Part No:

PC parallel port to CAN interface

This parallel connection to CAN converter is a sensible alternative to using a PCAN-USB adapter for connecting to a CAN network, especially for older PCs and laptops. Depending on the parallel interface present, it can be operated in "Multiplex" or "Enhanced Parallel Port" mode. Power is supplied to the PCAN-Dongle through a special adapter connected to the PC’s keyboard output.

The opto-decoupled version also guarantees galvanic isolation of up to 500 Volts between the PC and the CAN sides.

The package is also supplied with the CAN monitor PCAN-View for Windows® and the programming interface PCAN-Basic.
