12.1 RS-232 Software Configuration
To configure an RS-232 port
1. Select Controller from the Setup Menu and open the RS232 folder on the tree located
on the left side of the dialog.
If RS232 boards have not been installed on the controller, you will not see the
corresponding ports in the tree.
2. Select the port you want to configure.
3. Change the settings as desired.
4. Click Apply to save the new settings.
If the several ports are used in the communication at one time with more than 19200 baud
rate, error 2929 or 2922 may occur. In this case, select the lower baud rate or avoid using
several ports at one time.
