Introduction
The W406 embedded computer has two RS-232/422/485 serial ports, one 10/100 Mbps Ethernet
port, an embedded GSM/GPRS/EDGE module, an SD socket interface for storage expansion, one
USB 2.0 host port, four digital input channels, and four digital output channels. This combination
of features makes the W406 ideal for your wireless embedded applications.
RISC-based W406 embedded computers come with the Windows® CE operating system
pre-installed. Microsoft® Windows® CE 6.0 is an open, scalable, 32-bit operating system that
allows users to build a wide range of innovative, small footprint devices. A typical Windows®
CE-based device is designed for a specific use, and often runs disconnected from other computers,
or distributed as a front-end to a centralized host. Examples include enterprise tools, such as
industrial controllers, communications hubs, point-of-sale terminals, and display devices, such as
HMI, advertisement appliances, and interactive panels.
