5.Type the one-character code for the change you wish to make.

Baud Rate

The baud rate is the speed at which data is transmitted and received.

SELECTION CODE: E1

300 bps

A

1200 bps

C

2400 bps

D

4800 bps

E

9600 bps

F

19200 bps

G

Data Bits

Set the number of data bits used to define a character.

SELECTION CODE: E2

 

7 bits

A

8 bits

B

Parity

Serial communication can define a parity check bit to be added to each character. This check bit can be true for an odd number of “1” bits or an even number of “1” bits in the data character. The user may also choose to define the parity bit as a MARK (true) or a SPACE (false). Selecting NONE results in no parity bit.

SELECTION CODE: E3

Odd

A

Even

B

Mark

C

Space

D

None

E

Note: The reader must use a total of 10 or 11 bits to define a character frame. If you select “7” data bits with the “None” parity option, the reader will for- mat the character frame as 8 data bits and no parity.
