Overview
About the Lantronix UDS1100 / UDS1100-PoE
The UDS1100 (also written UDS 1100) connects equipment that only has a serial port, such as utility meters or fire and alarm panels, to an Ethernet network so it can be monitored and controlled remotely. It works by serial tunneling: serial data is packetized and carried over TCP/IP, so neither the attached device nor its software needs to change. Two UDS1100 units can also be paired to extend a serial link across a building or a WAN.
The serial port is software-selectable RS-232, RS-422 or RS-485 (2- and 4-wire) on a DB25F DCE connector, from 300 to 230 Kbaud, with RTS/CTS or XON/XOFF flow control. The network side is 10Base-T/100Base-TX on RJ45. The included Com Port Redirector with TruPort technology lets Windows applications open the remote port as a local COM port, including control of hardware pins. Modem emulation mode accepts AT commands, replacing dial-up modems and phone lines. The UDS1100 is UL 864 listed, so fire and alarm manufacturers can add networking to UL 864 products without reapplying to UL.
The metal enclosure measures 9.0 x 6.4 x 2.3 cm, weighs 0.20 kg and has integrated wall mounts, with an optional 35 mm DIN-rail kit. It operates from 0 to 60 C and is configured by web browser, Telnet, the serial port or Lantronix DeviceInstaller, which assigns IP addresses and upgrades firmware. For embedding the same function inside equipment, Lantronix offers a board-level version, the UDS1100-B.
Key capabilities
- RS-232, RS-422, RS-485
- One software-selectable serial port supports RS-232, RS-422 and 2- or 4-wire RS-485 at 300 baud to 230 Kbaud, so one model covers most legacy equipment.
- Virtual COM ports
- Com Port Redirector with TruPort technology maps the remote serial port to a local Windows COM port, including control of hardware pins and serial buffers.
- UL 864 listed
- The UL 864 listing lets fire and alarm panel manufacturers add Ethernet to their UL 864-listed products without reapplying to UL.
- PoE or local power
- The standard UDS1100 runs on 9-30 VDC or 9-24 VAC at 1.5W maximum; the UDS1100-PoE draws power from an 802.3af source over the Ethernet cable.
- Dial-up modem replacement
- Modem emulation mode accepts AT commands on the serial port and opens a network connection instead, eliminating dedicated modems and phone lines.
- Hardened I/O protection
- 15 kV ESD protection on the serial transceivers, 1500 VAC Ethernet isolation and 600 W transient protection on the power input.
How to choose the right UDS1100 / UDS1100-PoE part number
The three UDS1100 part numbers differ only in how the unit is powered. UD1100001-01 ships with a US 120 VAC power supply. UD1100002-01 ships with a 100-240 VAC international supply and regional adapters. UD11000P0-01 is the UDS1100-PoE, powered from an 802.3af PoE switch or injector with no local supply. Add ACDIN2001-01 for DIN-rail mounting, ACC-500-163-R for a DB25M to DB9F serial cable, or ACC-500-171-R to break the DB25 out to RS-485 and 9-30 VDC screw terminals.

UDS1100 / UDS1100-PoE FAQ
What is the difference between the UDS1100 and UDS1100-PoE?
Both are single-port serial-to-Ethernet device servers. The UDS1100 runs on 9-30 VDC or 9-24 VAC through a barrel connector and ships with an external supply. The UDS1100-PoE (UD11000P0-01) is powered over Ethernet from an 802.3af source, useful where there is no power outlet.
Does the UDS1100 support RS-485?
Yes. The serial interface is software-selectable between RS-232, RS-422 and RS-485 in 2-wire or 4-wire mode. The ACC-500-171-R adapter converts the DB25 connector to RS-485 and 9-30 VDC screw terminals.
Can I use the UDS1100 as a virtual COM port?
Yes. The included Com Port Redirector software with TruPort technology lets Windows applications access the UDS1100 serial port as if it were a local PC COM port, including monitoring and setting hardware pins.
What is the UDS1100 operating temperature?
The UDS1100 operates from 0 to 60 C (32 to 140 F) and can be stored from -40 to 85 C. The metal enclosure is rated IP30 and weighs 0.20 kg.
Can two UDS1100 units create a serial tunnel?
Yes. Two UDS1100 device servers can be configured to connect to each other automatically over the network, creating a virtual serial connection that extends serial communications across a facility or between distant sites.
