The MiiNePort E1 from Moxa is an ultracompact, embedded Serial-to-Ethernet device server, specifically designed for manufacturers who wish to equip existing serial devices with network capability without consuming much space or energy. The module is sized like an RJ45 connector (33.9 x 16.25 x 13.5 mm), making it particularly suitable for OEM designs where available space is limited. Due to its extremely low power consumption, it is also suitable for applications with limited power supply. The integrated network connection enables direct connection of serial devices to an Ethernet network, allowing data transmission via IP-based protocols.

Applications

The MiiNePort E1 is used in areas where serial devices need to be integrated into existing networks without requiring additional hardware or large module sizes. This includes industrial automation, machine integration, and OEM designs where the integration of serial interfaces into networks with minimal space and energy requirements is necessary. The compactness of the module makes it ideal for installation in devices that already have a fixed form factor.

Functions and Features in Detail

The device is based on Moxa’s second-generation MiiNe System-on-Chip (SoC), which integrates a 32-bit ARM7 core. This SoC features 2 MB Flash memory and 4 MB SDRAM, sufficient to support the required operating functions and configurations. The serial interface supports transmission rates up to 921.6 kbps, which is adequate for many industrial applications. The Ethernet connection operates at 10/100 Mbps, enabling stable and sufficiently fast network communication. Moxa’s integrated UART technology ensures reliable serial data transmission.

Technology Explained Simply

The MiiNePort E1 acts as a bridge between serial devices and an Ethernet network. It converts serial data into IP packets and forwards them over the network. The use of NetEZ technology enables simple and quick configuration. Features such as EXTrigger allow a restart or reset of the module via a button press, simplifying on-site maintenance. MCSC (Multi-Channel Serial Communications) enables the module to operate simultaneously as a server and client, which is useful in complex network environments. SCM (Serial Communication Mode) allows configuration via the serial interface, which is particularly useful for devices not directly accessible over a network. AutoCFG enables automatic mass configuration via software tools, saving time when setting up multiple modules.

Compatibility and Accessories

The module supports various operating modes, including Real COM, RFC2217, TCP Server/Client, and UDP. These modes enable flexible integration into different network environments. Real COM simulates a serial COM interface within the network, RFC2217 allows dynamic adjustment of baud rate, while TCP Server/Client and UDP are used for direct data transmission over the network. Compatibility with these protocols makes the module versatile for various industrial and machine applications.

Mounting and Installation

Installation is performed by direct integration into the serial device, with the module easily integrated into existing devices due to its small dimensions. The network connection is made via an RJ45 port, directly connected to the Ethernet network. Configuration can be done via various methods, including the serial interface (SCM) or network tools, depending on the desired operating mode. The small size and low power consumption facilitate installation in space-constrained environments.

Operational Advantages

Operation of the MiiNePort E1 is characterised by its compactness, energy efficiency, and flexible configuration options. Support for various operating modes and the use of NetEZ technology reduce integration and maintenance effort. Integration into existing networks occurs without additional hardware, reducing system complexity. The reliability of serial data transmission via integrated UART technology ensures stable communication, even in demanding industrial environments.
