6. Click Apply.
Configure the serial port for the serial communication parameters (baud
rate, data bits, parity and stop bits) required by the connected IA device. If
you configure the port for a slave, you do not have to configure a network-
based master. Communication with the master simply works. However, if
the master is connected to a serial port, it must be configured. If you
configure a port for a master and the slaves are located on the network,
TCP sockets, UDP sockets, and Modbus/TCP are all supported. Use the
protocol required by the master.
