If this option is enabled, the module will reset
the CAN controller and attempt to go back
online after a bus-off condition is detected.
If the option is disabled, the module will
remain offline after a bus-off condition until it
is power cycled.
For most applications, this option should be
left disabled.
If this option is enabled, data in the I/O table
will be byte swapped on 16-bit boundaries.
J1939 data is stored least significant byte first;
Modbus data is stored most significant byte
first. This option swaps the bytes in each
Modbus register (16-bit word) to facilitate
reading the J1939 data on Modbus.
Note: Module firmware revisions earlier
than 1.05.01 automatically swapped I/O
bytes; this option was not configurable, but
set in the module. Set this option to be com-
patible with earlier configurations.
Enabling the Offline Detection will allow the
module to detect when it is not connected to
the J1939 network when there is no Output
PGN's configured. See "Offline Detection"
on page 6-14 for a complete discussion.
The J1939 baud rate may be set to either 250K
or 500K baud.
Important: The standard J1939 baud rate
is 250K. Do not set the baud rate to a rate
other then 250K unless you know for certain
that the devices on the J1939 are communicat-
ing at the other baud rate.
