4.0 Configuration
Select operational status of the Com0/1 Serial Port. The port is
disabled by default.
Com0/1 Port Status
Values (selection)
Disabled
/ Enable
Determines which serial interface shall be used to connect to
external devices: RS232, RS485, or RS422. When an interface
other than RS232 is selected, the DE9 port will be inactive.
Channel Mode
Values (selection)
RS232
RS485
RS422
The serial baud rate is the rate at which the modem is to
communicate with the attached local asynchronous device.
Data Baud Rate
Values (bps)
Note: Most PCs do not
readily support serial
communications greater
than 115200bps.

This setting determines the format of the data on the serial port.
The default is 8 data bits, No parity, and 1 Stop bit.

Flow control may be used to enhance the reliability of serial data communications, particularly at
higher baud rates. If the attached device does not support hardware handshaking, leave this
setting at the default value of ‘None’. When CTS Framing is selected, the IPn4G uses the CTS
signal to gate the output data on the serial port.
Flow Control
Values (selection)
None

Software flow control
(XON/XOFF) is not
supported.
