Product Description

The simplyCAN is an active USB adapter which enables the user to connect a computer with a CAN network to monitor the network traffic and to interact with other network devices. The simplyCAN is a plug and play device due to the easy installation and the easy-to-use CAN programming interface.

Features

• USB 1.1 Full-Speed (12 MBit/s)
• 1 x CAN high-speed channel according to ISO 11898-2
• D-Sub 9 fieldbus connection, pin allocation according to CiA 303-1
• USB cable with plug type A

Windows: the simplyCAN is tested Windows 10 (64 bit).
Linux: the simplyCAN is tested using Ubuntu 16.04 (32 bit) on Linux kernel version 4.15 as well as Ubuntu 20.04 (64 bit) on Linux kernel version 5.4, and Rasberry OS 10 (buster) kernel version 5.4 (32 bit).

The performance is limited to 50-60 % for Rx and Tx directions each. For a busload higher than 50-60 % data loss is possible.

Installation

Insufficient power supply!
Connect the device directly to the computer or to self-powered hubs to ensure sufficient power supply. Extension cables may cause connection issues.

On Windows 10 and Linux the USB interface is automatically installed when plugged in, without a driver installation.
Download the simplyCAN package for the operating system in use from www.simplycan.info and unpack the files.

The COM interface for the simplyCAN is showed as USB Serial Device (COMx) in the device manager when plugged in. To show the simplyCAN as Ixxat simplyCAN (COMx) in the device manager, execute the file setup.bat.

  • Plug the USB connector in the USB port of computer.
    → Hardware is automatically found and installed.
    → USB LED is green flashing.

  • If necessary install a bus termination (see CAN Bus Termination, p. 10).

  • Connect the CAN fieldbus connector to the CAN fieldbus.

  • Start the simplyCAN bus monitor (see Operation, p. 8).

Connectors
The shield of the USB cable is connected to ground using a 100 nF capacitor. The shield of the CAN connector is connected to CAN ground via a 1 MΩ resistor and a 10 nF capacitor. USB_shield is connected to CAN_shield via a 4.7 nF capacitor.

For best noise immunity connect the shields of the CAN cables directly to the device ground.

Operation

simply CAN Bus Monitor

01-Operation

  • Start the simplyCAN bus monitor.
    → If one simplyCAN is connected to the computer, the device is automatically selected and connected (1).

  • If several simplyCAN are connected to the computer, select the desired device (1) and click button Connect (2).
    → Information about the device are displayed (4).
    The simplyCAN bus monitor can be opened several times to connect several simplyCAN devices simultaneously.

  • To change the device, click button Disconnect (3), select the device in drop-down list Select device (1) and click button Connect (2).

  • Select the desired CiA baudrate (5).

  • To start the communication, click button CAN start (6).
    → CAN messages are shown in the window Output (8).
    → In transmitted messages the time stamp is 0 and the flag S is displayed.

  • To send a message, enter the message in the Transmit line (9) (see Transmit Messages, p. 9 for more information).

  • Click button Send (9).
    → If the entered message is valid, the message is transmitted.
    → If the entered message is invalid, the error message Syntax error and a description of the message format is shown.

  • Stop the communication with button CAN stop (7).

  • Clear the output window with button Clear (10).

  • For a busload higher than 50-60 % data loss is possible. Data loss is signalled by the Ovr LED in the simplyCAN bus monitor.

Transmit Messages
Syntax: [R] [E] […]

• id: identifier (decimal or hexadecimal)
• R: remote transmit request for message
• E: message in Extended frame format (29 bit)
