5.2.3 CONFIGURING OUTPUTS
Output Mode
There are two ways to configure the outputs. All configuration is done through the same PGN. PGN 61408 is used for multiple
messages by use of a different value put into the “command” byte of the PGN. This value is used a an index or pointer as to where the
information goes in the module.
A. Global Output Configuration
(only used if you want all the outputs to be configured the same)
Configuring all of the outputs is done through the “MODE1” byte in PGN 61408. The J1939 message structure,
The frequency set point must be greater than 0 for any output to function.
