Lantronix UD1100001-01 UDS1100 one-port serial (RS232/RS422/RS485) to IP device server (UL864)
Quick take
The Lantronix UD1100001-01 UDS1100 adds a single RS232/RS422/RS485 serial device to an Ethernet network using a DB-25 connection and a 10/100 Mbps RJ-45 port. It is a good match for setups that need remote access to one legacy serial endpoint and support for network-based control. The main tradeoff is that it is a one-port solution, and the available buyer-review evidence is limited, so it is best for shoppers who already understand their serial protocol and cabling needs.
Pros and cons
Pros
- Single serial port supports RS232, RS422, and RS485 for broad legacy compatibility.
- Includes a DB-25 serial interface plus a 10/100 Mbps Fast Ethernet RJ-45 port.
- UL864-compliant design with wall-mountable and rail-mountable mounting options.
- Uses “Serial over IP” technology for network-based connectivity to serial devices.
Cons
- One-port device, so it is not the right choice if you need to connect multiple serial devices with one box.
- Buyer-review evidence is sparse, so real-world feedback on setup and day-to-day behavior is limited.
- You must confirm your equipment uses the right electrical interface (RS232 vs RS422 vs RS485) and cabling for the DB-25 connection.
What buyers think
Buyer-review coverage for this model is limited. The available feedback is mainly focused on general purchasing and delivery satisfaction rather than detailed discussion of performance, connectivity reliability, or configuration experience. As a result, buyer-review evidence is too limited to draw a reliable pattern about strengths or weaknesses in day-to-day networking and serial bridging.
What this device server does, in plain terms
The UD1100001-01 UDS1100 is designed to “convert” a serial connection into something that can ride over an Ethernet network. Instead of running a legacy device only through local serial wiring, you connect the serial side through the device server’s single DB-25 serial port, then connect the device server to your network via the 10/100 Mbps Ethernet RJ-45 port. This setup is commonly used to enable remote access, monitoring, and network-based management for equipment that predates widespread IP connectivity.
Key specs that matter for purchasing
Serial compatibility and physical connections
- Serial interface: One DB-25 serial port.
- Supported serial types: RS232, RS422, and RS485.
- Best fit: A single legacy serial endpoint you want to expose over Ethernet.
Network side
- Ethernet speed: 10/100 Mbps Fast Ethernet RJ-45.
- Connection type: Ethernet (network transport for serial over IP).
Power and computing
- Processor: Runs on a Lantronix DSTNI-EX 48 MHz processor (positioned for reliable performance in the device server line).
- Input context: US domestic 110VAC (relevant if you are matching power requirements in an enclosure).
Mounting and deployment
- UL864 compliance: Built for controlled-environment installation use cases.
- Mounting options: Wall mountable and rail mountable.
Pros and cons for real buyers
Who it’s best for
- Teams that need to connect one RS232/RS422/RS485 serial device to a network for remote management or monitoring.
- Shoppers standardizing legacy equipment access by moving serial endpoints into an IP-based workflow.
- Installers who value straightforward physical mounting options (wall or rail) for panel or enclosure builds.
Who should look elsewhere
- If you need multiple serial ports, you will likely want a multi-port device server instead of a one-port unit.
- If you do not already know your serial electrical standard (RS232 vs RS422 vs RS485) and how it maps to the DB-25 wiring you have, you may spend time sorting out cabling and configuration before the system works as intended.
- If you want strong buyer-feedback patterns about setup and reliability, note that the available review evidence for this exact model is limited.
Is the Lantronix UD1100001-01 UDS1100 worth it?
It is worth considering when your priority is adding one legacy serial device (RS232/RS422/RS485) to a standard Ethernet network using a DB-25 connection, and when installation needs include wall or rail mounting (UL864). The value case weakens if you need multiple ports, if your serial requirements do not align cleanly with a DB-25-based serial interface, or if you rely on extensive real-world review patterns to reduce risk.
For many shoppers, the simplest buying path is to verify two things first: (1) your equipment’s serial type and cabling approach for DB-25, and (2) that a one-port device server fits your deployment size. If both check out, this unit is a focused solution rather than a general-purpose multi-device gateway.

Alternatives to consider (based on use case)
- If you need more than one serial device: Look for a multi-port serial-to-Ethernet device server that can map several serial endpoints in the same box.
- If you only need network-to-serial access for a small, fixed system: Compare options by the number of ports, supported serial standards, and physical connectors (DB-9 vs DB-25 style), then choose what matches your existing wiring.
- If your network environment requires specific integration: Filter by Ethernet speed class (10/100 vs gigabit), mounting requirements, and how the “serial over IP” feature is typically configured in your workflow.
FAQ
What serial standards does the UD1100001-01 support?
It supports RS232, RS422, and RS485 using its single DB-25 serial port.
