## Long description

The Lantronix UDS1100 Serial Server provides a single-port solution to connect RS-232/RS-422/RS-485 devices to Ethernet. Compact and compliant with RoHS/WEEE, the UDS1100 supports 10/100Base-T(X) and common network protocols (TCP/UDP/HTTP/DHCP/Telnet/SNMP) and includes a web server and on-board Flash for firmware and custom web pages. A model with Power over Ethernet (PoE) is available and the unit meets UL 864 9th Edition requirements for fire and alarm panel integration.
Advantages
The UDS1100 enables rapid network integration of serial equipment without changing existing device software by using serial tunneling and Lantronix Com Port Redirector. It supports modem emulation to replace dial-up modems and can be configured locally or remotely via serial, Telnet or a web browser. TruPort Com port control provides full control of serial port signals and buffers from Windows applications. Small size and multiple configuration options make it suitable for constrained spaces and varied deployment scenarios.
Suitable for
Adding network connectivity to industrial equipment with RS-232/422/485 ports
Remote monitoring and control of instruments, sensors and controllers
Replacing dial-up modems and dedicated modem lines with Ethernet or PoE
Integrating UL 864-listed fire and alarm panels into IP networks
Extending serial communication across facilities or between remote sites
Key specifications
Interfaces: RS-232, RS-422, RS-485 (single serial port)
Network: 10/100Base-T(X), ARP, TCP, UDP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, SNMP
Power: 100–240 V input (PoE model available)
Certifications: RoHS, WEEE compliant; meets UL 864 9th Edition
Physical: 72 x 23 x 95 mm; weight 0.4 kg
Indicators and storage: LAN status LEDs; on-board Flash for web pages and firmware
How to use
Install the UDS1100 near the serial device and connect the serial interface (RS-232/422/485) and Ethernet cable. Configure network parameters using the built-in web server, Telnet, serial console or the DeviceInstaller utility. For Windows applications, install Lantronix Com Port Redirector to map remote serial ports to local COM ports or configure two UDS1100 units in paired mode to create a virtual serial link across the network. If using modem emulation, send standard AT commands to the serial port to initiate network calls.
Usage recommendations
Place the UDS1100 in a dry, ventilated location and ensure firmware is kept up to date via the web interface or DeviceInstaller. Use the PoE model where local power is not available and secure network access with appropriate firewall and authentication measures when exposing device servers to unfamiliar networks.
