1.1.4 Data transfer rate
The data transfer rate of an interface is given in 'baud' and indicates the number of bits of data
transmitted in one second.
1 baud = [1 Bit
s ]
Common baud rates are:
110, 150, 300, 600, 1200, 2400, 4800, 9600, 19 200 and 38 400 baud.
The time taken to transmit one bit (t B ) can be calculated from the baud rate:
"1"
"0"
t B
t B =
1
Baud rate[ bits
s ]
For example, a baud rate of 19,200 baud will have a bit duration of t B = 52.083 μs.
The number of characters transmitted per second can be calculated from the baud rate and the
transmission format:
Baud rate[
Characters per second =
bits
s ]
Number of bits per character
Example:
With a transmission format of seven data bits, one start bit, two stop bits and a data transfer rate of
exactly 300 baud:
300 Baud
10 bits
will be transmitted.
= 30 characters per second
