The MiiNePort E1-T from Moxa is an Embedded Device Server for TTL-based serial devices, specifically developed for integration into OEM applications with limited space. With a compact form factor of 33.9 x 16.25 x 13.5 mm, barely larger than an RJ45 connector, it enables Drop-in-Integration into existing systems. It serves as a bridge between serial interfaces and Ethernet networks, making TTL devices controllable and monitorable over IP networks. The solution is designed for industrial environments where a robust, space-saving, and reliable communication connection is required.

Applications

The MiiNePort E1-T is suitable for applications where serial devices such as sensors, controls, or industrial peripheral devices need to be integrated into existing networks. Typical use cases include industrial automation, building automation, machine building, or embedded systems where Ethernet connectivity is required for TTL interfaces. Its compact design makes it particularly suitable for devices where no additional space is available for external converters.

Functions and Features in Detail

The server features an MiiNe-SoC with a 32-bit ARM core, 2 MB flash memory, and 4 MB SDRAM, providing sufficient resources for processing serial data and network protocols. It supports a variety of operating modes, including Real COM, TCP Server/Client, UDP, and RFC2217, allowing flexible use in different network environments. Moxa’s NetEZ-Technology simplifies integration: features such as EXTrigger (external reset), Serial Command Mode (SCM), and AutoCFG (automatic configuration) enable quick and error-free setup without manual intervention.

Technology Explained Simply

The E1-T connects a TTL interface with an Ethernet port. The TTL interface supports baud rates from 50 bps to 230.4 kbps, data bits from 5 to 8, stop bits 1, 1.5, or 2, and parity types including None, Even, Odd, Space, and Mark. Data transmission can be controlled via flow control using RTS/CTS or XON/XOFF. On the Ethernet side, it provides a 10/100BaseT(X) port with RJ45 connector and integrated magnetic isolation of 1.5 kV, protecting against electrical interference. The integrated isolation enhances communication stability and safety, especially in industrial environments with high interference levels.

Compatibility and Accessories

The MiiNePort E1-T is compatible with a wide range of operating systems, including Windows (all common versions including Embedded), Linux (kernel 2.4 to 5.x), UNIX derivatives such as SCO, QNX, Solaris, and Android from version 3.1.x. Software support includes Real COM drivers for Windows and Real TTY support for Linux, facilitating integration into existing systems. Additionally, the device features I/O functions: one digital input, one digital output, and one software-configurable DIO, which can be used for additional control and monitoring tasks.

Mounting and Installation

Installation is performed via the Drop-in design, where the module is directly integrated into the existing hardware. It is powered by an external 3.3 VDC supply, with a current consumption of 160 mA. Mounting requires no additional components or tools; the module is directly inserted into the circuit board. Configuration is done via NetEZ-Technology, often eliminating the need for manual settings.

Operational Advantages

The MiiNePort E1-T is characterised by high operational reliability. The operating temperature ranges from -40 °C to 85 °C, making it suitable for extreme environments. Storage is permitted from -40 °C to 60 °C at a humidity of 5 to 95 % (non-condensing). Certifications include EMC standards such as EN 55032/35 and FCC Part 15B Class B, as well as EMS tests according to IEC 61000-4 series (ESD, EFT, Surge, RS, CS). Additionally, the device meets requirements for shock (IEC 60068-2-27), vibration (IEC 60068-2-6), and environmental tests (IEC 60068-2-1/-2/-3). The MTBF is 5,515,294 hours according to Telcordia SR332, indicating high reliability over a long period. The warranty is 5 years.

Certifications and Compliance

The device is RoHS, CRoHS, and WEEE compliant, ensuring environmental compatibility and proper disposal according to EU directives. EMC and EMS certifications guarantee reliable operation in electromagnetically noisy environments. Mechanical stress resistance according to IEC 60068-2-27 (shock) and IEC 60068-2-6 (vibration) makes the device suitable for industrial applications where mechanical shocks may occur.
