Projection dataTransfer Projection dataBaud rate


The term Baud rate describes the number of distinct symbol changes made to the transmission medium per second.


The number of signs transferred per second depends on the settings of the following transfer parameters:


Number of bits per sign
Use of parity
Number of stop bits


The Baud rate is calculated as follows:


Number of symbol changes per sign = Startbit + Number of bits per sign + Parity* + number of Stop bits

* If parity is None, value = 0, otherwise = 1


Number of transferred signs = Baud rate * number of bits per sign / number of symbol changes per sign



The Baud rate is only relevant if transfer is made via an RS232 interface (also known as V.24).

Internally, the PC calls these interfaces COM1 to COM4.


The Baud rate settings must correspond with the settings at the connected operator interface.

The Baud rate directly correlates with the time needed for a data transfer.

The higher the Baud rate, the faster the data transfer.

The maximum possible Baud rate depends on the quality of the data connection.

This connection quality is determined by the cable parameters and the cable length.



The tables below list the Baud rates currently achievable:

If the data is transferred via an Ethernet interface the speed of the data transfer depends on the Ethernet standard used.


Currently in use are:

100 Base = 100Mbits/s
1000 Base = 1000Mbits/s
