External Device Server - In minutes, securely connect factory floor devices to enterprise systems - Access, monitor and control equipment over Ethernet - Replace dedicated PCs and/or modem lines with fast and reliable Ethernet networking - Supports RS-232, RS-422 and RS-485 communications - Includes Modbus TCP, ASCII, RTU and DF1 protocols - 15kV serial ESD protection - Wide -40°– 70°C operating temperature range - Environmentally-friendly RoHS and WEEE-compliant The UDS1100-IAP is a rugged and powerful tool which enables users to connect, manage and control just about any piece of industrial equipment from virtually anywhere over Ethernet or the Internet. This single-port Device Server is a quick, simple and inexpensive way to bring the advantages of real-time or on-demand information access. Standards Based Communications Using an open Ethernet architecture as a standard provides the flexibility for equipment to communicate to virtually any type of industrial device. When used in conjunction with an OPC server, most Windows based HMI, SCADA and PC-based control applications have full access to information in the industrial equipment networked by the UDS1100-IAP. Extending Serial Communications Across the Globe Our approach to network-enabling devices is transparent to your attached equipment and software so you won’t need to change the way you work. Using a method called serial tunneling, the UDS1100-IAP encapsulates serial data into packets and transports it over Ethernet. Serial tunneling can be done in multiple ways: - Using Lantronix supplied Com Port Redirector software, Windows device applications not designed for network communications are re-directed to communicate to devices connected to the UDS1100-IAP. - Connecting two UDS1100-IAP Device Servers configured to automatically talk to each other over the network creates virtual serial connections that can extend serial communications across a facility or around the world. Built-in Web Server The built-in web server enables users to access and configure the UDS1100-IAP from a standard web browser. Web pages enabling the UDS1100-IAP 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, nonvolatile web page storage. Easy to Set Up and Use The UDS1100-IAP can be set up locally through its serial port, or remotely using Telnet or a web browser. The included DeviceInstaller™ Windows-based configuration software simplifies setup and provides an easy way to: - 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 - Simplify process of installing industrial protocols Complete with an auto MDI/MDIX Ethernet interface, the UDS1100-IAP is a powerful device communication solution that’s perfect for your most demanding industrial applications. Modem Replacement In modem emulation mode, the UDS is used to replace dialup 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 logoRoHS-compliant, the UDS1100-IAP meets Directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment. If you’re looking for a transparent, cost-effective, and scalable means to network-enable your industrial automation equipment, look no further than the UDS1100-IAP.

Evolution Device Server- Dual-purpose Ethernet terminal server and device server design- Rack-mountable, data center-ready device / Ethernet terminal servers, with 8, 16 and 32 serial ports- Put just about any piece of equipment with a serial port on the enterprise network with robust “data center grade” security, including AES, SSH and SSL- Offers a fully programmable device computing platform based on- corporate IT standards – Cisco-like CLI, XML, RSS- Print server functionality (LPR/LPD)- Powerful web manager for easy device configurationEDS is a unique, hybrid Ethernet terminal and multi-port device server product designed to remotely access and manage virtually all of your IT/networking equipment and servers, as well as edge devices such as medical equipment, kiosks, POS/retail terminals, security equipment and much more.Delivering a data center-grade, programmable device computing and networking platform for integrating “edge” equipment into the enterprise network, rack-mountable EDS models are available in available in 8, 16 and 32 port configurations.Featuring Evolution OS, our powerful real-time networking operating system, they deliver an unprecedented level of intelligence and security to networked equipment. With these innovative, versatile products, multiple electronic devices can become secure members of the corporate network that can be accessed and managed from virtually anywhere, at any time.Easy to SetupWithout requiring any special software, these multi-port device servers can connect up to 8 to 16 or 32 RS-232 serial devices to your network in a matter of minutes. Using a unique method called “serial tunneling,” they encapsulate serial data from the device into packets to transport it over Ethernet.Setup is a breeze with the included Windows-based DeviceInstaller™. The EDS can also be set up locally via a serial port, or remotely over a network using Telnet, a web browser or SNMP.Bullet-proof SecurityEvolution OS provides a ‘data center-grade’ level of protection so each device on the network carries the same level of security as IT equipment in your corporate data center. The EDS feature robust defenses to hostile Internet attacks such as denial of service (DoS) and port mapping that could be used to take down your network. The hardened OS and mature protocol stack prevent the device servers from being used to bring down other devices on the network. And with built-in AES, SSH and SSL, they provide robust key management algorithms that:- Verify that any data received came from the proper source- Validate that data transferred from the source over the network is unchanged when it arrives at its destination- Provide the ability to run popular M2M protocols over a secure SSH or AES connectionWith SSH and SSL, they support a variety of popular cipher technologies including 128/256/512/1024-bit AES (Rijndael), 3DES and RC4 Encryption Public/Private keys and hashing algorithms such as SHA-1 and MD5. HTTP authentication uses Base-64, Digest Authentication and SSL.Standards-Based CommunicationsCisco-like CLI – The EDS utilizes a Cisco-like command line interface (CLI) with syntax very similar to that used by data center equipment such as routers and hubs. This industrystandard tool simplifies configuration and control, making it easier to integrate edge devices or data center equipment into the enterprise network.XML-based Architecture – XML is a standard tool for web services, data transfer and rich content management that encapsulates data into a text-based format. XML-based configuration and setup records in the EDS make device configuration transparent and easily modified with a standard text or XML editor.PowerfulEight MB of Flash memory provides maintenance-free, nonvolatile storage of web pages, and enables future system software upgrades. Featuring a 32-bit XScale processor and 64MB of RAM.Com Port RedirectorLantronix Com Port Redirector software is included. It redirects application data destined for a local serial (COM) port on a PC to a serial port on the EDS. Data sent from the equipment to the device server is transmitted back to the application over the network. Com Port Redirector then presents the data to the application as if it were from a local serial COM port.
