Note: ( ) required parameters, < > optional parameters for parameter input
Function:
The command sets the baud rate for serial communication.
NOTE
When the baud rate is changed, communication is not possible at first. The computer also
has to switch over to the new setting (baud rate). For the change in the baud rate to be
permanent, it has to be saved in the EEPROM using the command TDD1. This procedure
ensures that the baud rates set in the WE are all supported by the remote station. If the
newly entered baud rate is not saved, when the system is reset or started up again, the WE
will answer at the previous baud rate.
Example: BDR?; 3,1crlf corresponds to 9600 baud, parity bit even
Example: BDR4; WE responds at 19200 baud
Example: BDR3; WE responds at 9600 baud,
Parity is unchanged
