6.6.2. RS-232 Parameters Settings
The parameters of local RS -232 port can be set as follows.
Command and Response
ȩ {RS232_LOCAL_FORMAT=<BaudRate>;<DataBit>;<Parity>;<StopBit>}
Ȩ (RS232_LOCAL_FORMAT=<BaudRate>;<DataBit>;<Parity>;<StopBit>)CrLf
Parameters
Parameter Parameter description
<BaudRate> Baud rate
<DataBit> Data bit
<Parity> Parity
<StopBit> Stop Bit
Example
ȩ {rs232_local_format=9600;8;O;X}
Ȩ (RS232_LOCAL_FORMAT=9600;8;O;X)
Explanation
RS -232 port is set as the following: the baud rate to 9600, data bit to 8, parity to odd, and stop bit is not
changed, remained 1.

INFO: The actual RS-232 parameters can be queried by the {RS232_LOCAL_FORMAT=?} command.
