Serial Port Profiles
TruePort Profile
Overview
TruePort is especially useful when you want to improve data security, as you can enable an SSL/TLS
connection between the TruePort host port and the IOLAN. TruePort is COM Port redirector that is
supplied with the IOLAN. TruePort can be installed as a client on a Workstation or Server and
supports a variety of operating systems. It, in conjunction with the IOLAN, emulates a local serial
port (COM port), to the application, to provide connectivity to a remote serial device over the
network. The TruePort profile operates in conjunction with the TruePort software.
Functionality
TruePort is a COM port redirector utility for the IOLAN. It can be run in two modes (these modes
will be set on the client software when it is configured):
z TruePort Full mode—This mode allows complete device control and operates as if the device
was directly connected to the Workstation/Server’s local serial port. It provides a complete COM
port interface between the attached serial device and the network. All serial controls, baud rate
control, etc., are sent to the IOLAN and replicated on its associated serial port.
z TruePort Lite mode—This mode provides a simple raw data interface between the application
and the remote serial port. Although the port will still operate as a COM port, control signals are
ignored. In this mode, the serial communications parameters must be configured on the IOLAN.
See the TruePort User’s Guide for more details about the TruePort client software.
General Tab Field Descriptions
The TruePort General tab determines how the TruePort connection is initiated and then sets up the
appropriate connection parameters.
