# Setting Up the CAN Interface

Before using any CAN dongle with FLIP, the dongle API should have been properly installed, as described in the CAN Pre-Installation Requirements topic.

The CAN Setup dialog lets you configure the CAN interface parameters. There are many different available CAN interfaces, or dongles and they may be connected to the PC parallel, RS232, PCMCIA or USB port.

- Parallel port dongle :

select the LPTx port from the Parallel list box

- RS232 port dongle :

select the COMx port from the RS232 list box, then set the RS232 baudrate from the proper list box.

- USB dongle :

there is no particular setup for the USB.

Connect to the CAN dongle by clicking the Init button.

Set the Node and the CRIS values in hexadecimal format, without any 0x prefix; note that the ISP commands IDs change when you modify the CRIS value. The higher allowed value for the CRIS is 7F.

Click the Init button to initialize the CAN dongle hardware.

Click the Node Connect button to start an ISP session with the specified node. The Node Connect button toggles the connection to the node : if the node was connected, it is unconnected; if the node was previously unconnected, it is connected and the device information (signature and other bytes) is read and displayed in the device frame of the main window.
