Quickly Network Enable Equipment Allowing Remote Monitoring
and Management From Anywhere on the Net

Lantronix UDS1100-B Device Server, can quickly and easily network-enable electronic equipment with a serial interface so it can be remotely accessed and controlled over the Net. This flexible product is designed to be integrated with the circuit board of devices like factory machinery, security systems, heating and ventilation systems, lighting control systems and point-of-sale devices.

Building networking capability into a product can be a complex task. The UDS1100-B offers a flexible and easy-toimplement networking solution which enables OEMs to concentrate on their core competency, reduce time-tomarket and quickly increase product value.

Extending Communications Across the Globe

Using a method called ‘serial tunneling,’ the UDS1100-B encapsulates serial data into packets and transports it over Ethernet. Serial tunneling can be done in multiple ways:

  • Using two Device Servers connected by a network, virtual serial connections can be extended across a facility or around the world.
  • Implementing Lantronix COM Port Redirector™ software simplifies the integration process by extending the functionality of (serial) COM port-based Windows® applications. It redirects application data destined for a local serial (COM) port on a PC over the Ethernet network and through the UDS1100-B enabled device. Communications to or from the networked equipment is processed by the PC application as if it were from the local COM port.
  • OEMs that have control over their application source can also modify their applications to communicate directly to the UDS1100-B.

Easy to Set Up and Use

The built-in web server enables users to access and configure the UDS1100-B from a standard web browser. Web pages enabling the Device Server to be customized for unique applications can be built using Lantronix development tools. On-board Flash memory provides room for future system software upgrades and maintenance-free, non-volatile web page storage. The UDS1100-B can be set up locally through its serial port, or remotely using Telnet or a web browser. The Lantronix DeviceInstaller™ Windows-based configuration software simplifies setup and provides an easy way to:

  • Discover and group devices on the local network
  • Assign IP & other network specific addresses
  • Load custom web pages
  • Enable web-based configuration of the Device Server
  • Ping or query the attached device(s) over the network
  • View specific device data files
  • Upgrade firmware

Modem Replacement

In modem emulation mode, the UDS is used to replace dial-up modems. The unit accepts modem AT commands on the serial port. It then establishes a network connection to the end device, leveraging network connections and bandwidth to eliminate dedicated modems and phone lines.

RoHS-compliant, the UDS1100-B meets Directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
