5.3.3 CONFIGURING INPUTS
Input Mode
Inputs can be configured in 2 ways, globally, or individually. Both configurations types use 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 as an index or pointer as to
where the information goes in the module.
A. Global Input Configuration
(Only used if you want all the inputs to be configured the same. Only works for digital configuration.)
Configuring all of the inputs is done through the “MODE2” byte in PGN 61408. The J1939 message structure,
