The CANPORT is a simple, yet powerful way to connect a PC to a Controller Area Network (CAN). At the heart is the Intel 82527 CAN interface chip. The 82527 interfaces to the PC through the parallel port using the synchronous serial peripherial interface (a clocked serial interface). Although the interface is slower than a parallel interface, this interface performs adequately for most applications where a low-cost interface is needed.

The device that connects the 82527 to the network is the 82C250 interface IC. The 120 ohm termination resistor can be jumper selected if required. Provisions for additional capacitance can be added by populating C7 and C8.
