1.Synchronization: Asynchronous

2.Baud Rate: RS-232D: 75, 110, 134.5, 150, 200, 300, 600, 1,200, 1,800, 2,400, 4,800, 9,600, or 19,200 BPS (selectable)

RS-422A: 75, 110, 134.5, 150, 200, 300, 600, 1,200, 1,800, 2,400, 4,800, 9,600, 19,200, or 38,400 BPS (selectable)

Current Loop: 75, 110, 134.5, 150, 200, 300, 600, 1,200, 1,800, 2,400, 4,800, 9,600, or 19,200 BPS (selectable)

3.Word length: Start bit: 1 bit

Data bit: 7 or 8 bits (selectable)

Parity bit: Odd, even, none, or ignore (selectable)

Stop bit: 1 bit or more

4.Input signal polarity:

1)RS-232D:

MARK = logic "l" ( - 3 to - 25V) SPACE = logic "0" ( + 3 to + 25V)

2)RS-422A:

MARK = logic "1"

The RDA is negative (-0.2 V to -6 V) with respect to the RDB.

SPACE = logic "0"

The RDB is positive (+0.2 V to +6 V) with respect to the RDB.

R D A : Inverted R D B : Noninverted

3)Current loop:

MARK = logic "1" (Current on) SPACE = logic "0" (Current off)
