New Eagle DBC CAN Networking Toolbox
New Eagle DBC CAN Networking Toolbox
Overview
New Eagle's Network Toolbox makes it easy to create CAN input and output blocks in MotoHawk. Instead of manually writing code in MATLAB to handle CAN messaging, Network Toolbox enables you to have useful CAN blocks starting from an industry-standard .dbc file to describe the CAN network. This saves development and debugging time and reduces complexity. With the free DBC file editor like the Kvaser Database Editor, you can also create your own custom .dbc files.

Licensing
As of Network Toolbox 2014b, Network Toolbox uses the standard New Eagle License Viewer.
Licensing FAQ
- Question: I purchased a Network Toolbox license but when trying to use it I get a message (such as the one below) directing me to contact New Eagle Support.
- Answer: This message indicates that an obsolete version of Network Toolbox is installed on your computer and/or MATLAB path. Please uninstall and remove from your MATLAB path. Current versions of the network toolbox integrate with the MATLAB startup and don't require manually adding the library to your path. New Eagle recommends that you use the latest version of Network Toolbox to ensure the best compatibility, feature set, and stability. Keeping your software maintenance up to date is the best way to assure that you have access to the latest releases and support.
Editing DBC files
To edit and create dbc files you could use the Database Editor which is available for a download in the required files download section.
FAQ's
Multiplexing
- Question: How do I select a signal from a multiplexed CAN defintion?
- Answer: The “Message Mode” parameter in the Network Toolbox will allow you to demux a single message from a multiplexed CAN message definition.
- Question: Multiplexing doesn't appear to be working properly, how can I verify my implementation?
- Answer: You should see the Network Toolbox create a block similar to the one on the right. For example, this block has a 3-bit Message Mode of value 5, starting at bit 49 Little Endian, (highlighted in yellow). You should see a similar payload mask and value corresponding to your multiplexed message based on the bit location and mode of the multiplexing. If the multiplexing is not creating a mask as you expect, ensure the dbc file is formatted correctly.
Error Codes
- Question: Is there a method to detect J1939 error codes?
- Answer: For J1939 received messages using the NE Network Toolbox, check the Raw output checkbox. This will additionally output the raw (unscaled, no offset) value, so that, in the application, it can be checked if the engineering value is invalid or unavailable per J1939. Note that this checking logic needs to be done in the application, which takes some effort; the Network Toolbox is capable of outputting the raw value to aid in this effort.
Block Error
- Question: Why does my block give me a CBIOS4NET64 error when I try to open it?
- Answer: This can be fixed by updating your Network Toolbox, or by unplugging the MotoHawk dongle when opening the block. This is an issue that may happen on select machines.
Licensing Questions
License purchase includes a perpetual license the current release and following (e.g. 2015a/2015b). Access to subsequent releases are made available with active software maintenance.
For Network Toolbox, 2015a version will work with MotoHawk 2015a and prior. If you want to use a new version of MotoHawk you must be current on maintenance with Network Toolbox.
