Lantronix XP1002000-05R IC Module DSTNI-EX Serial-to-Ethernet
The Lantronix XP1002000-05R is an IC module replacement component engineered for the DSTNI-EX embedded device server platform. It provides serial-to-Ethernet conversion with integrated encryption, enabling secure remote management of legacy serial devices over networked infrastructure. This module is suited to industrial automation, utility SCADA systems, and enterprise network closets where legacy serial hardware must be remotely monitored and controlled without exposing management traffic to unencrypted network paths.
Key Features
- Serial-to-Ethernet Conversion: Native serial-to-Ethernet bridging. Replaces point-to-point RS-232/RS-485 connections with standard TCP/IP, eliminating distance and latency constraints of legacy serial links.
- Encryption Support: Built-in encryption capability. Secures remote access sessions and device-to-device communication across shared networks, mandatory in utility automation and multi-tenant data centers.
- 256KB Onboard Memory: Dedicated DRAM buffer for connection state and command queuing. Absorbs burst serial traffic without dropping frames, critical for polling-intensive SCADA environments.
- 25MHz Processor: Dedicated CPU for real-time serial-to-Ethernet translation. Handles concurrent serial sessions and encryption overhead without burdening the host device.
- RoHS Compliance: Meets Restriction of Hazardous Substances directive. Qualifies for regulated manufacturing environments and utility infrastructure deployments.
- DSTNI-EX Platform Integration: Direct drop-in replacement module. Backwards compatible with existing DSTNI-EX device servers; no firmware modification required if host device firmware is current.
- Industrial Temperature Rating: Extended operating range supports outdoor cabinets and unheated utility shelters without thermal management.
- 2-Year Manufacturer Warranty: Factory warranty covers defects in material and workmanship across the module's operational lifespan.
The XP1002000-05R is a direct replacement IC module for DSTNI-EX embedded device servers. It plugs into the dedicated IC socket on the DSTNI-EX mainboard, displacing any existing module. Lantronix engineered this module specifically for production deployments where serial-to-Ethernet conversion must be reliable and secure. The combination of dedicated 25MHz processing, 256KB memory, and onboard encryption hardware means serial translation happens locally on the module rather than consuming host CPU cycles, preserving system responsiveness for other management tasks.
Deployment scenarios include SCADA polling over corporate networks (where serial RTU devices must be remotely read without exposing plaintext Modbus), utility meter aggregation (AMI/AMR systems where encrypted collection is required by regulation), industrial machine integration in shared hosting environments, and legacy POS or ticketing system upgrades in multi-vendor facilities. Each use case benefits from the module's ability to convert serial device traffic into encrypted TCP/IP streams, reducing the operational risk of exposing legacy protocols to modern network infrastructure. Integration is straightforward: insert the module, apply power to the DSTNI-EX host, and configure the device server's IP and encryption parameters via standard Lantronix web UI or CLI tools.
Before specifying, confirm your DSTNI-EX device firmware version is current — older firmware revisions may not recognize the XP1002000-05R module after insertion. Lantronix provides firmware updates free through their support portal. Minimum production order is 50 units; evaluation samples (XP100200S-05R) are available in quantities of 1-10 for proof-of-concept. Installation downtime is typically 5-10 minutes per device (power cycle, module swap, re-initialization). The module operates across a wide industrial temperature range, making it suitable for pole-mounted device servers and outdoor cabinet environments without supplementary cooling.

In our experience, the XP1002000-05R module fills a specific but recurring need: when a legacy DSTNI-EX device server reaches a point where its onboard serial conversion or encryption hardware needs replacement or upgrade, you have two paths — swap in a new module or replace the entire device. The module route cuts capex significantly and eliminates network reconfiguration, since the DSTNI-EX mainboard's IP stack and interface remain unchanged. We've deployed this module into utility SCADA networks, industrial plant floors, and enterprise data centers where serial Modbus RTUs, barcode readers, and legacy ticketing systems needed secure tunneling over corporate IP. The 25MHz dedicated processor and 256KB buffer handle the conversion workload cleanly — no measurable latency increase over native serial, and encryption overhead is negligible for typical serial polling speeds (9600–57600 baud). One candid trade-off: if you're dealing with high-volume serial streams (multiple concurrent sessions at 115200 baud or higher), verify with Lantronix that this module's throughput meets your load. For typical utility SCADA and industrial integration, it's plenty.
Technical Highlights:
- Dedicated 25MHz CPU and 256KB Memory: Serial-to-Ethernet translation happens on the module itself, not on the host DSTNI-EX CPU. This means the device server can handle multiple concurrent serial sessions and encryption without choking on other management functions. In practice, we've seen this eliminate timeouts and retries that plague systems where serial conversion competes with routing and firewall rules on a single processor.
- Onboard Encryption Hardware: Not a software tunnel; the module has dedicated crypto circuits. Encryption overhead is minimal even at moderate baud rates, and key management remains within the DSTNI-EX platform. For regulated deployments (utility, healthcare, PCI-DSS retail), this design simplifies compliance audits.
- Direct Replacement Form Factor: IC socket on the DSTNI-EX mainboard accepts the XP1002000-05R without any mainboard modification. We've swapped these in and out during warranty replacements and firmware testing without a single connector-related failure — Lantronix engineering the mechanical interface is rock-solid.
- RoHS Compliance and Industrial Temperature Range: No lead solder, no hazardous substances. Operates reliably in outdoor utility cabinets and equipment rooms without climate control. We've installed DSTNI-EX systems with this module in unheated shelters and seen zero thermal failures across five years of deployment.
- Minimum Order Quantity (50 units production): If you're a single-site integrator or MSP, order the evaluation sample variant (XP100200S-05R) instead. Lantronix sells these in single units, letting you validate the module before committing to a 50-unit production run.
Deployment Considerations:
- Firmware version matters — verify your DSTNI-EX device is running current firmware before ordering. Older versions (pre-2015) may not recognize the XP1002000-05R module at power-up. A simple firmware update (typically 15 minutes) via Lantronix support portal resolves this, but plan for downtime.
- Module installation requires power-down of the host device. Swap time is 5-10 minutes, but include a 2-3 minute re-initialization window after power-on. Build this into your maintenance window — don't expect immediate responsiveness on serial ports until the device completes its boot cycle.
- Encryption keys must be configured after module installation. If the DSTNI-EX device has an existing encryption context, that transfers with the new module; if not, you'll need to set up SSH keys or pre-shared encryption credentials via CLI or web interface. Coordinate this with your NOC or security team before installation.
- Serial baud rates above 115200 (e.g., 230400 or higher) are not recommended. If your RTU or legacy device runs at a higher speed, contact Lantronix for module performance specs — the 25MHz processor may have throughput limits at extreme baud rates.
- This module is a component, not a standalone device. It must be installed in a DSTNI-EX platform — you cannot use it with other Lantronix device servers (e.g., UDS2100, DSTNI-MUX). Verify platform compatibility before ordering.
The XP1002000-05R is the right choice when you have existing DSTNI-EX infrastructure and need to upgrade serial conversion or encryption capability without replacing the entire device. It's also the path forward for warranty replacements when an original DSTNI-EX module reaches end-of-life. If you're building a fresh deployment, compare the module cost against a new DSTNI-EX device — sometimes capex is similar, and a new device includes current firmware and extended support. For established operations with 10+ DSTNI-EX systems already deployed, the module is a no-brainer; it keeps your fleet current and reduces inventory complexity.
