CAN Cable

The following images show a simple do-it-yourself cable that connects the DB9 of the USB to CAN Gateway to the 3 pin Molex CAN connector of an IO board.  This schematic details the pin connections.

The cable is a shielded 3 conductor cable and the Molex connector is Digikey part #WM3212-ND.  The piece of breadboard was scrap from other projects.  Note that the shielding has been used as a strain relief by soldering it to the body of the DB9 connector and to the breadboard.  It is a simple matter to use a slightly larger piece of breadboard to daisy chain the cable to multiple IO boards.
