Device Server Makes M2M Implementation A Snap

If you've been trying to implement a machine-to-machine (M2M) application, you know you have to cobble together the right mix of computers, interfaces, and software. Now there's a faster, easier, and cheaper way. Lantronix's UDS1100 device server lets you network virtually any device in minutes.

With the UDS1100, getting M2M data to corporate back-end systems has never been easier. It also can be used to replace with modems or dedicated modem hardware. Applications include industrial automation, building monitoring and control, medical monitoring, point-of-sale, security, and audio-visual/entertainment. You also can check your home's security and video cameras via a cell phone.

The UDS1100 lets users monitor, manage, share, and control almost any type of equipment over any Ethernet localarea network or the Internet. It has a single standard 10BaseT or 10BaseTX 10/100-MHz Ethernet port with an RJ-45 connector. It supports the ARP, UDP, TCP, ICMP, Telenet, TFTP, AutoIP, DHCP, HTTP, and SNMP TCP standards.

A single DB25F DCE serial port connector for RS-232, RS-422, or RS-485 (two or four wires) serial devices lies on the other end of the box (see the figure). The data rate is selectable from 300 to 230 kbaud. The server also can handle bytes with 7 or 8 bits, odd-even-none parity, and 1 or 2 stop bits. Control is CTS/RTS in hardware, and flow is XON/XOFF in software.

The UDP1100 uses serial tunneling to transmit the data. It encapsulates the serial data into packets and transports them over Ethernet. Designers can complete the serial tunneling with Lantronix's Com Port Redirector software.

Device applications not designed for network connections are redirected to communicate to devices connected to the USD1100. Or, users can connect two UDS1100 device servers configured to automatically talk to each other over the network. This creates a virtual serial connection that can extend serial communications across a facility or around the world.

With its Web server, users can access and configure the UDS1100 from a standard Web browser. Users also can create Web pages that will enable the customization of the UDS1100 for unique applications. Extra flash memory provides storage space for future systems software upgrades and maintenance-free, nonvolatile Web page storage.

Users can set up the UDS1100 locally through the normal serial port or remotely using Telenet or a Web browser. The Windowsbased Lantronix DeviceInstaller simplifies setup and provides an easy way to assign IP and other network addresses, load custom Web pages, enable Webbased configuration of the device server, ping or query the attached devices over the network, view specific device data files, or upgrade the firmware.

The UDS1100 fully complies with the European Union's Restrictions on Hazardous Substances. It operates from a singe 9- to 24-V source through a standard barrel connector or via the DB25F connector. Measuring just 3.5 by 2.5 by 0.9 in., it's small enough to fit anywhere.
