4.0 WebUI Configuration
Port Status
Enable
Disable
Values
Select operational status of port. Enabled by default.
*COM2 is Disabled by default. If COM2 is Enabled and there is a desire to
switch it back to Disabled (console mode) via the serial connection to it, the
escape sequence of ‘
+++
’ may be entered at the Data Baud Rate for which
the port is configured.
Channel Mode
Determines which (rear of unit) serial interface shall be used to connect to
external devices: RS232, RS485, or RS422. This option applies only to
COM1 / DATA. When an interface other than RS232 is selected, the DE9
port will be inactive.
RS232
/ RS485 / RS422
Values
Data Baud Rate
Values (bits per second (bps))
The serial baud rate is the rate at which the modem is to
communicate with the attached local asynchronous
device.
*COM2 data baud rate maximum is 115200bps.
921600

Note: Most PCs do not
readily support serial
communications greater
than 115200bps.
Data Format
Values
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
Values
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 IPn3G uses the CTS
signal to gate the output data on the serial port. Figure
3A below illustrates the timing of framed output data.
*COM2 does not support Flow Control.
