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 7-1. 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:
