CAN232 FD User Manual 1-1
1. Overview
1.1 Introduction
The CAN232 FD enables the use of an RS232 COM port to send and receive CAN messages on an
ISO11898 CAN or CAN FD network.
The CAN232 FD can be configured to operate in either the serial command mode or the serial tunnel mode,
providing the user with a choice as to the type of functionality desired.
In the command mode, the CAN232 FD is capable of sending and receiving arbitrary CAN messages
through the serial port, providing a complete CAN-to-232 interface. This mode also supports message
filtering to limit the range of CAN identifiers that will be received.
In Tunnel mode, the CAN232 FD establishes a full-duplex virtual serial link between itself and an
application on another CAN node. A serial device can transparently send and receive serial stream data on
the CAN232 serial line and the CAN232 will route the data over CAN to the configured target device. In
previous versions of the product this feature was referred to as virtual circuit (VC) mode.
The CAN232 FD operating mode and all other configuration parameters are accessed through the ‘config’
button. Pressing the button causes the CAN232 FD to enter configuration mode where it then prompts the
user to modify configuration parameters. In addition to parameter configuration, the configuration mode
also provides diagnostic tools.
The CAN232 FD represents an evolution of the earlier CAN232 product line, providing a performance
increase and enhanced features, while retaining much backward compatibility.
The CAN-RS232 version is shown below.
The new units are based on an ARM Cortex-M0+ 32-bit microcontroller. All device interfaces (UART,
CAN) have built-in hardware buffers that allow for high-speed data flow without data loss. Hardware
buffering, coupled with a fast and efficient CPU, allows each interface to operate at its maximum rated
limit.
The new hardware version is now equipped with an isolated CAN interface standard.

1.2 Hardware Description
The following drawing shows the location and function of the LEDs.
1.3 Model Description
The CAN232 FD platform has the option of DTE (male) or DCE (female) on the RS232 serial cable. It has a
Male DB9 CAN connector.
