available functions are listed in that chapter as well.
These are configurable input functions only, and not available for standard switch
input channel configuration.
4.3.11 J1939
The DCU supports a large number of the standard SAE J1939 SPNs. To verify that a SPN is
supported, the DCU supports a search mechanism in the web interface. Either search by
one term or several. If several search terms are used they must all match.
home / dcu / i/o configuration / j1939
In order to configure a SPN, either search for it using the search mechanism provided or
browse through the supported SPNs in the left side column.
For instance, if looking for “Fuel Rate” signal, select D-F in the left side column.
Depending on the SPN selected for configuration, it can be configured as a standard analog
channel or a standard switch channel.
Some SPNs are categorised as enumerable SPNs, such as SPN 3543 (Engine
Operating State). These are configured similar to standard switch channels with
the exception that the event configuration is extended to the different enumerable
states of the SPN.
