4. Serial Port Configuration
4.1. Overview
The serial port configuration capability allows the user to configure the host mode of each port, serial
communication parameters, cryptography, port logging parameters and other related parameters.
The serial port’s host mode can be set as any of the following:
TCP
:
The Pro Series operates as a TCP server and client. If the connection is not established, it
accepts all incoming connections from any registered remote hosts and connects to the registered
remote hosts if there is any data from the serial devices. Otherwise, it will send data back and
forth. In summary, the Pro Series will work as if it is virtually connected to the remote host.
UDP
:
The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.
Modem emulation
:
Select this mode when the serial device becomes ready to support modem AT commands or
users want to perform the session control by using AT commands. Only TCP session is supported.
With the
port-logging
feature while in console server mode, the data sent through the serial port is
transferred to
MEMORY
or
NFS server’s storage
. The user can also define keywords for each serial
port that will trigger an email or SNMP trap notification. This will enable the user to monitor the data
from the attached device.
Using
MEMORY
to store data will result in loss of all information when the Pro Series is turned off.
Use the
NFS server
to preserve the serial port log data.
The serial ports can be configured individually or all at once.
