Lantronix manual XPress DR+ Application Examples, Example of Serial Tunneling

Chapter 2: Introduction

Loading industrial protocols such as Modbus Bridge to an XPress DR+ changes the configuration dialogs. See the user guides on individual protocols for protocol-specific settings and configuration dialogs. Protocol manuals are on the software CD.

Note: This User Guide describes the setup and configuration dialogs for the Standard Tunnel Protocol.

XPress DR+ Application Examples

Note: For XPress DR+W application examples, see Chapter 4: XPress DR+W.

Using a method called serial tunneling, the XPress DR+ encapsulates serial data into packets and transports them over Ethernet. Using two XPress DR+ units, connected by a network, you can extend virtual serial connections across a facility or around the world.

Figure 2-2. Example of Serial Tunneling

The internal two-port Ethernet switch allows the XPress DR+ to cascade connections from a single network drop to another Ethernet device or from one XPress DR+ to another and another, and so on.
