CAN Bus 

VBOX TOUCH FW v1.5 - Select Settings.png

The CAN Bus menu is where you can configure the settings for your CAN data capture. The menu is split into two sub-menus, one for each isolated CAN port on the VBOX Touch unit.

You can set each port to one of the following modes: CAN input, Racelogic (RL) modules or CAN output. When you set it to CAN output, VBOX Touch will be transmitting its own GNSS-derived data, including lap timing data, to a third-party CAN logger.

CAUTION:

Connect to the vehicle CAN bus at your own risk. 

CAN Settings

Your first option is to select which port you want to configure the CAN settings for. Use the Forward and Back arrows in the bottom right-hand corner to navigate between the two ports and their settings. The settings options are the same for both the top and bottom port. 

CAN Mode

This setting lets you choose which CAN mode you want to use for this port. You can choose between RL Modules, Input, Output and Disabled. Press on the '?' to see an overview and an explanation of the different CAN modes available. 

When you have selected the CAN mode you want to use, you will get the option to configure the selected mode. Press the Configure button that appears below your CAN Mode selection.                                                  
RL Modules

When you select to configure the input from an RL Module, you will first have to select the RL modules you are connecting to. 

You have 6 available modules and can choose to connect to one or more. Select them by pressing the respective tick boxes on the left-hand side and pressing the Confirm button to confirm your selection. 

Press the Cancel button if you want to return to the CAN Mode screen without saving.

When you are using RL modules, you have to set them to Timed CAN mode with default output message identifiers. You must do this in VBOX Setup before you start logging. 

Note:

  • You can find configuration files for compatibility with the VBOX Touch RL MODULES mode on the Automotive Website for quick configuration.
    • Follow the link and click on the Modules tab. Scroll down until you see RACELOGIC Module configuration files for use with VBOX Touch and click Download. You can upload the appropriate file to the module via the VBOX Setup software.
  • Make sure that the termination is set to enabled when you are capturing module data.
  • If you want to capture data from multiple modules of one type, such as 2 x IMU modules, you must either separate the capture across the two ports or use Input mode. If you are using more than two modules, you will have to use the Input mode and set the modules up in a daisy chain. You can find more information about this under Input Modules under the Input section further down on this page.

Input

When you select to configure the port to capture CAN Input, you will first have to select which database you are using to decode incoming data.

You will get a list of options and can either choose the internal vehicle CAN database or you can load external DBC files from the SD card onto the unit to select from.

To use the internal vehicle database, choose Select from the vehicle CAN database. This will give you a list of available channels with a comprehensive list of makes and models. Select the channels you wish to log by pressing the respective tick boxes on the left-hand side and pressing the Confirm button to confirm your selection. 

Press the Exit button if you want to return to the CAN Mode screen without saving.

Note:

  • The Internal CAN database must be loaded onto the unit before you can use it. The database is a separate upgrade file that is included in the beta firmware download. 
  • There is a limit of 64 logged CAN channels, applied across both CAN ports.
  • You must make sure that the Baud rate and termination settings match your expected connection.

Input Modules

You can use Input mode to capture single or multiple CAN modules or if you need to capture multiple RL modules of the same type (in a daisy chain).

When setting up a daisy chain, you must:

  • Set the modules to Timed mode.
  • Change the default output identifiers for each added unit of that type (to something unique).
  • Construct or load your own (singular) database file that has channels for all the modules you are connecting to. 

After confirming the modules you want to use, you will see the Input Modules screen. This screen is split into halves, with your selected modules on the left-hand side and the logged channels on the right-hand side. 

Tap on one of the channels on the right-hand side to edit it. 
Logged Channels

When you have confirmed the modules you want to use, the Input Modules screen will be displayed. This screen is split into halves, with your selected modules on the left-hand side and the logged channels on the right-hand side. 

Tap on one of the channels on the right-hand side to edit it. 
Edit Selected Channel

This settings screen has relevant information for the selected channel. You can configure the name, units, scale, and offset, and you can see the channel value if it is connected and transmitting data. 

Use the forward and back buttons to navigate to the previous or next available channel.

Press the Confirm button to confirm your edits and go back to Input modules.

Depending on the selected module, you may get the option to calculate the scale and offset. When you select one of the following modules, you will see a CALC button next to the scale and offset values.

  • Micro Input Module (MICIN) - all channels
  • Mini Input Module (MIM) - analogue channels only
  • Analogue to digital (ADC03) - all channels

 Press the CALC button to open the Scale and offset calculator.

After you have configured your channels, you will see that the Configure button in the CAN settings has changed to Edit. Press Edit to see the channels you have configured to log. If you want to make a change to the configured channels, press the Change Selection button at the bottom of the screen. 

You can now add or remove the channels in the currently selected database, or you can press Change Database to choose a different database to select channels from. 
Output

Both ports have the ability to output GNSS and Lap Timing CAN data from the VBOX Touch. You can export and save the CAN database (to decode) directly from the unit to the SD card, by using the Save Output DBC file function. This option will be available when you select Output as your CAN mode.           
Termination and Baud Rate

In addition to selecting the CAN mode and the logging channels, you can also Disable/Enable Termination and set the Baud Rate.

Note: When you are using the internal CAN database, termination and baud rate will be set automatically.
If, at any point, you have any questions or issues regarding CAN capturing on VBOX Touch, please contact Racelogic Support.
