    2.4 Mode Options 2.4.1 Get Mode In the command mode (CM), the CAN USB-232 is capable of sending and receiving arbitrary CAN messages via the use of ASCII formatted message strings. In virtual circuit mode (VC), the CAN USB-232 establishes a full-duplex, virtual circuit between itself and another CAN USB-232 or application device.

  • Page 28: Set Com Port

    2.6.2 CAN Bus State During Configuration While the CAN USB-232 is in the configuration mode, the CAN controller is in the bus-off state. It does not interact with the bus and is effectively ‘invisible’. Thus, it is possible to perform configuration of the CAN USB-232 while still connected to an active CAN network and not adversely affect network operation.

  • Page 33: Message String Syntax

    Normal CAN Message Syntax : <S | X> <IDENTIFIER> <N> <DATA-0> <DATA-1> … <DATA-7> ; The first character,‘:’, is for synchronization and allows the CAN USB-232 parser to detect the beginning of a command string. The following character is either ‘S’ for standard 11-bit, or ‘X’ for extended 29-bit identifier type.

  • Page 34: Rtr Can Message

    2.7.4 Appending CR/LF To Received Command Strings When using the CAN USB-232 to view received CAN messages directly on a terminal, the user can set a configuration parameter to append a <CR> <LF> sequence to each message string generated. This makes it easier for the user to see each received message as each message will be on a separate line.

    The CAN USB-232 only sends CAN messages when eight bytes of data have been received. This leads to a case where the last part of a data stream is not sent if it is less than eight bytes long. To deal with this in a transparent fashion, the CAN USB-232 provides a timeout feature that will automatically force a transmission of the last accumulated byte(s) after a specified maximum waiting time.

  • Page 40: The 'Xmit' And 'Rcev' Identifiers

    When a CAN message containing this identifier is received, the data in the message is assumed to be stream data from another CAN USB-232. This data is then read and output directly to the serial COM port of the receiving CAN USB-232 unit, providing the completion of the virtual circuit.

  • Page 50: Defining Filter Entries

    2.10.1 How Filtering Works Whenever the CAN USB-232 receives a CAN message from the network, it checks to see if any filters are enabled. If none of the filters are enabled, it assumes no filtering should be performed and outputs the ASCII message string of the message to the serial port.
