Using a method called serial tunneling, the xDirect encapsulates serial data into packets and
transports them over Ethernet. Using two xDirect units, connected by a network, virtual serial
connections can extend across a facility or around the world.
Figure 2-1 Serial Tunneling Example
The Com Port Redirector software available for download at
www.lantronix.com/support/downloads simplifies the integration process by extending the
functionality of COM-port-based Windows™ applications. Virtual COM ports, mapped to remote
device servers on the network, can replace direct serial connections.
