I/F (Interface) Mode

The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation. The default setting is 4C.

I/F Mode (4C) ? _

The following table displays available I/F Mode options:

Note: All bit positions in the table that are blank represent “don’t care” bits for that particular option, which can be set to either a 0 or 1 value.

Table 8-2 Interface Mode Options

I/F Mode Option	7	6	5	4	3	2	1	0
RS-232C (1)							0	0
RS-422/485 4-wire							0	1
RS-485 2-wire							1	1
7 Bit					1	0
8 Bit					1	1
No Parity			0	0
Even Parity			1	1
Odd Parity			0	1
1 stop bit	0	1
2 stop bits(1)	1	1

(1) 2 stop bits are implemented by the software. This might influence performance.

The following table demonstrates how to build some common Interface Mode settings:

Flow

Flow control sets the local handshaking method for stopping serial input/output. The default setting is 00.
