CAN

This page contains an overview of the features and settings in the CAN Menu in VBOX Setup connected to VBOX 4 ADAS.

The CAN menu is where you can export dbc files, set the CAN baud rate, set the output rate, set the CAN termination and configure and enable full bus logging for the CAN FD ports.

Bus Loading

VBOX4ADAS v1.1_Setup_CAN_BusLoading.svg

In the top right-hand corner of the CAN menu, you will see this Bus loading graphic.

It will display the current load on the CAN bus, so you can see the load applied to the bus as you add channels. We recommend a maximum load of 70%. If the CAN bus loading exceeds the recommended 70%, the CAN bus may become unstable and samples may be lost. You can reduce the bus load by increasing the baud rate or reducing the number of output IDs.

Settings Tab

Baud Rate
VBOX4ADAS_CAN_Settings_CAN_BaudRateOptions.png

The baud rate sets the bit rate of the CAN messages (not the frequency at which the messages are sent). 

The default setting is 500 Kbit/s as most light vehicles use that baud rate. 

The available baud rate options are:

  • 1 Mbit/s
  • 500 kbit/s
  • 250 kbit/s
  • 125 kbit/s 
  • Custom
Custom Baud Rate

VBOX4ADAS_CAN_Settings_CAN_CustomBaudRate.png

If you wish to use another baud rate than the specific baud rate settings, you can select the Custom option and click the Edit button. This will open a window where you can set your own custom baud rate.   

Output Rate
VBOX4ADAS_CAN_Settings_CAN_OutdateRateOptions.png

This setting controls the CAN output update rate for the purpose of resolving bandwidth limitation issues.

The available output rates are:

  • 100 Hz
  • 50 Hz
  • 20 Hz
  • 10 Hz
  • 5 Hz
  • 1 Hz
Termination
VBOX4ADAS_CAN_Settings_Settings_CAN_Termination.png

Ticking the Termination box will add 120-ohm resistance to the CAN bus connection. 

Note: If you add or remove termination on the CAN port, you must power-cycle the VBOX after writing the settings to the unit. 
Configure CAN Input
VBOX4ADAS_CAN_Settings_Settings_CAN_ConfigureCANInput.png

Click on the Configure CAN Input button to open the CAN Input section in the Channel Setup menu to further configure your CAN channels.  
CAN FD 1 Port

The default name for the bus is CAN FD 1 but you can edit the name in the text box. 
Termination
VBOX4ADAS_CAN_Settings_Settings_CAN_Termination.png

The Termination toggle switch will enable/disable 120-ohm resistance to the CAN bus connection on the CAN FD 1 port. 

Note: If you add or remove termination on the CAN port, you must power-cycle the VBOX after writing the settings to the unit. 
Baud Rate
VBOX4ADAS_CAN_Settings_Settings_CANFD_BaudRate.png

The baud rate sets the bit rate of the CAN messages (not the frequency at which the messages are sent). 

The default setting is 500 Kbit/s.

The available baud rate options are:

  • 500 kbit/s
  • 250 kbit/s
  • 125 kbit/s 
CAN FD
VBOX4ADAS_CAN_Settings_Settings_CAN_CANFD.png

The CAN FD toggle switch enables/disables the CAN FD logging on the CAN FD 1 port.

When you enable this setting, the Data rate setting becomes available. 

When this setting is disabled, the CAN FD 1 port will only log CAN 2.0.
Data Rate
VBOX4ADAS_CAN_Settings_Settings_CANFD_Data Rate.png

When you are logging CAN FD, you will also need to define the required data rate. 

The available data rate options are:

  • 5 Mbit/s
  • 4 Mbit/s
  • 2 Mbit/s
CAN FD 2 Port
