Port Configuration Setting
Go to Field Communication > Bus & Protocol > Port Configuration tab.
In the "Port Configuration" page, there is only one configuration window for the serial port settings. The
"Configuration" window lets you specify serial port parameters including the operation mode being "Virtual
COM", "Modbus" or disabled, the interface being "RS-232" or "RS-485", the baud rate, the data bit length, the
stop bit length, the flow control being "RTS/CTS", "DTS/DSR" or "None", and the parity.
Port Configuration Window
Displays the serial port ID.
The number of serial ports will vary depending on gateway model.
Disable is set by default
Displays the current selected operation mode for the serial interface. Depending
on the model, the available modes can be Virtual COM, Modbus, and IEC 60870-
5.
Select RS-232 or RS-485 physical interface for connecting to the access device(s)
with the same interface specification.
Select the appropriate baud rate for serial device communication.
RS-232: 1200 / 2400 / 4800 / 9600 / 19200 / 38400 / 57600 / 115200
RS-485 can use higher baud rate for 230400 and 460800. It depends on cable
length and the installation environment.
Select 8 or 7 for data bits.
Select 1 or 2 for stop bits.
Select None / RTS, CTS / DTS, DSR for Flow Control in RS-232 mode.
Support for Flow Control depends on the model.
Select None / Even / Odd for Parity bit.
Click Edit button to change the operation mode, or modify the parameters
mentioned above for the serial interface communication.
