Viewing CANBUS Communication MatrixUnlike many products currently on the market, the Orion BMS provides the customer with theability to customize and program precisely what data is transmitted on the CANBUS interfaces.Because of this unique capability, there is no standard or default communication matrix orCANBUS database file available as it could theoretically be different for every customerdepending on how the unit is configured.Since it is not possible to maintain a standard definition database, the best and most accurateway to view the current communication matrix is to review the settings in the BMS utility itselfwhich also allows the operator to export them as a DBC database file (which also done throughthe BMS utility itself). The following steps can be used to view / export this information:1) Open the relevant Orion BMS control utility. Please note that some BMS products willrequire a specific version of the BMS utility. These can all be downloaded on the mainOrion BMS website at: <a data-fr-linked="true" href="http://www.orionbms.com/downloads">http://www.orionbms.com/downloads</a>2) Connect to the BMS using the utility as shown below.<img src="https://uploads.gorgias.io/q0jJY2DYVzv7eBWM/undefined-3b9fb1c2-4b03-43b0-8c61-b39960907ed1" style="width: 664px;" class="fr-fic fr-dib">3) Click the &#x201C;Receive Profile From BMS&#x201D; button to download the current settings from theBMS. This ensures that the profile settings being viewed are the same as those storedon the BMS itself.NOTE: If you do not download the current profile first, the settings being viewed may notbe correct. Alternatively, the profile can be loaded from disk if it is available.4) Navigate to the &#x201C;CANBUS Settings&#x201D; tab and click on the &#x201C;Edit CANBUS Messages&#x201D;button in the middle of the screen. This is illustrated below.<img src="https://uploads.gorgias.io/q0jJY2DYVzv7eBWM/undefined-dc6ce909-2350-42e5-8aa7-bd4a02732d0a" style="width: 683px;" class="fr-fic fr-dib">5) This dialog brings up the active (programmed) CANBUS communication matrix asshown below. This is also where the matrix can be adjusted or changed to suit the needsof the application. Selecting an individual field will display additional information (such asthe bit order, byte order, scaling, etc). ID, transmission rate and other data are also here.<img src="https://uploads.gorgias.io/q0jJY2DYVzv7eBWM/undefined-a82578d8-b9d0-45c4-b8a7-6db321d923da" style="width: 692px;" class="fr-fic fr-dib">The entire CANBUS matrix can be exported to a DBC database file (a common file format fordescribing CANBUS message definitions) by selecting the Export DBC button on this dialog aswell, which will then prompt the operator to select a location on the computer to save theexported file to. The DBC file can then be opened by a DBC database editor.

CANBUS is a high speed network which requires high quality wiring in order to operate properly. As such, it is sensitive to improper wiring. The majority of CANBUS communication problems are caused by poor wiring, incorrect termination, or the use of
