Data Transfer Rate - HEIDENHAIN TNC 415 Technical Manual

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.

Common baud rates are:
110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200 and 38400 baud.
The time taken to transmit one bit (t B ) can be calculated from the baud rate:
"1"
"0"
t B
t B =
For example, a baud rate of 19,200 baud will have a bit duration of t B = 52.083 s.
The number of characters transmitted can be calculated from the baud rate and the transmission
format:
Characters per second =
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
= 30 characters per second
10 bits
will be transmitted.
