DESCRIPTION
The Mini Gateway Ethernet (MGE) is a device
that allows you to access your wireless network
through an Ethernet interface, and supports the
use of a ModFLEX module.
The wireless module in the MGE can be
commanded and controlled through a IP
connection using the module’s host protocol.
In addition the MGE comes with an internal web
server that can be accessed by any PC with an
Ethernet connection. The web server can be
customized via a programming development
environment.

DATASHEET
GATEWAY OVERVIEW
The MGE provides a pass-through capability for applications that require connectivity between a
wireless network and an Ethernet network. Command and control of the module is achieved through
the host protocol commands. See the MGE Host Protocol guide for more details. These These
commands can also be exercised though the ModFLEX Test Tool Suite.
The internal software architecture of the MGE consists of the following:
FreeRTOS (Operating System)
lwIP (light weight IP Stack)
FatFs (FAT File System)
HTTP Web Server
ModFLEX Module Driver
Microcontroller
The MGE uses the Stellaris® LM3S6911 microcontroller from Texas Instruments. The Stellaris®
LM3S6911 microcontroller is based on the ARM® Cortex™-M3 controller core operating at 50 MHz,
with 256 kB single-cycle flash, 64 kB single-cycle SRAM, 10/100 Ethernet MAC/PHY.
