Serial Port Properties - Serial Connection

If you check the Serial Port connection method on the Serial tab in the Port Properties dialog box, you need to define the following:

Baud Rate

Enter the baud rate for communications. Click the drop-down list to the right of the input field and select a rate from the list.

Parity

Select the parity to be used for communications.

Remember that you must configure the same baud rate, data bits, parity, stop bits and flow control for all PLCs using the serial port.
