World’s Smallest Embedded Device Server

24 June 2009

Seen for the first time at Hannover Fair, the tiny MiiNePort embedded device servers are designed for manufacturers who want to add sophisticated network connectivity to their serial devices—with a minimum of integration effort. The device server converts typical serial input, such as RS-232 signals, so that the data can be transmitted on Ethernet.

The key to making the MiiNePort so small is the MiiNe, which is Moxa’s second generation System-on-Chip (SoC). It supports 10/100 Mbps Ethernet and up to 921.6 Kbps serial baud rate. The chip uses a 32-bit ARM core and Moxa’s own UART technology. It has 2 MB flash and 4 MB SDRAM memory built in.

The MiiNePort is built in the size of an RJ45 connector (34 mm x 15 mm), making it easy to fit into virtually any existing serial device.

The server comes with a selection of ready-to-use operation modes, and requires only small amounts of power: 160 mA @ 3.3 VDC input.

The embedded NetEZ technology built into the MiiNePort can be used to convert any device with a standard serial interface to an Ethernet enabled device. It gives serial device manufacturers a range of tools for integrating Ethernet capability into their serial devices.

A special feature is EXTrigger, a tiny red button at the rear of the device. Designed for troubleshooting, the trigger can reset network settings with one click.

Moxa is providing a MiiNePort E1 Starter Kit, which includes the MiiNePort E1 module, an evaluation board, power adaptor, software, and serial and Ethernet cables. The kit allows evaluation of all embedded device server functions. The evaluation board itself is equipped with serial, Ethernet, digital I/O, and power circuits to help users test MiiNePort modules and applications.
