The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation. The
current value is displayed in parentheses.
I/F Mode (4C) ? _
Note:
RS-422 and RS-485 are available on Channel 2 only if the WiPort NR
embedded device server is used with the WiPort NR evaluation board.
Otherwise, RS-422 and RS-485 functions are available on only one channel;
depending on which channel the drivers were added, these functions are
available on either channel 1 or channel 2.
The following table displays available I/F Mode options:
