I/O Diagnostic Information
The position of DIP Switch SW4 determines whether or not you receive Terminator
I/O diagnostic information. If SW4 is in the OFF (default) position, you will receive
this diagnostic information and you must allow for two additional bytes on the input
(RX) and two additional bytes on the output (TX) for Terminator I/O diagnostic
functions.
If SW4 is placed in the ON position, you will not receive this diagnostic information
and there is no need to allow for the additional bytes.
Following is a description of the diagnostic codes.
Diagnostic (polling) information whenT1K–DEVNETS (slave) transmits to a master.

24V Error or Fuse Error
The slot number in which the error has occurred.
When the same error occurs by multiple slots,
priority is given to low slot number.
Priority is given to 24V Error or Fuse Error when
multiple errors occur at the same time.
