  • SSL, AES and DES encryption plus web OTA upgrade secure remote deployments

Serial-to-Ethernet Module Pack

This pack contains ten Vszerda Eport-E20 modules that convert serial data to 10/100 Mbps Ethernet using a Cortex-M3 MCU with 128 KB SRAM and 2 MB Flash. Each unit runs FreeRTOS and supports TCP, IP, Telnet and Modbus TCP protocols. The modules operate on a 3.3 V supply and include an RJ45 port with LED indicators. They are suited for engineers adding network connectivity to legacy serial equipment.

Industrial Automation Integrators

The modules suit integrators who need reliable serial-to-Ethernet bridges for factory floors, building management or remote monitoring across a wide temperature range. They also fit developers who require web-based configuration, SSL, AES or DES encryption and over-the-air firmware updates. Buyers needing gigabit Ethernet speeds, Power-over-Ethernet supply or multiple serial ports on one module should look at other solutions.

Operating Temperature Range

Each module is rated for continuous operation from -40 °C to +85 °C, meeting industrial-grade environmental demands. This wide range decides whether the part fits outdoor enclosures, unheated cabinets or harsh process environments. If the installation stays within standard commercial temperatures, the same spec still applies but less critically.

Questions about this item

How can I confirm the Eport-E20 module is operating correctly after wiring it up?

The RJ45 port LEDs indicate link and activity on the 10/100 Base-T connection, and the web configuration page shows real-time logs so you can verify TCP/IP, Telnet or Modbus TCP traffic is passing through the serial interface at up to 921600 bps.

What does the 10-piece pack contain and is anything else required to start development?

The pack supplies ten Eport-E20 embedded modules, each with a Cortex-M3 MCU, 128KB SRAM, 2MB Flash, FreeRTOS, one RJ45 port with LEDs and a TTL serial interface; you must provide a 3.3V power source and any enclosures or cabling for your application.

Which version should I choose if my equipment runs in environments from -40 to +85 °C?

All ten modules in this pack share the same industrial-grade specification, rated for continuous operation from -40 to +85 °C, so there is no separate version to select for that temperature range.
