Overview
The UC-7408 data acquisition embedded computers feature 8
RS-232/422/485 serial ports, an 8-ch digital input and 8-ch digital
output, dual 10/100 Mbps ports, a PCMCIA interface for wireless
LAN communication, and CompactFlash slot for mass storage disk
expansion.
The digital I/O feature of the UC-7408 series provides users with the
convenience of connecting digital devices to a front-end embedded
computer. The UC-7408 can be used for on/off event handling by
reading the state change of the digital input signal. In addition, output
signals from external digital devices can be imported through the UC7408’s digital input channels, and the UC-7408 can be programmed
to take immediate action when it detects a change in the state of the
signal.
The digital output channels on the UC-7408 can connect to devices
and trigger digital output signals to control external digital devices.
With the digital I/O feature, Moxa’s embedded computers support both
data acquisition and protocol conversion through the RS-232/422/485
serial ports, and simple I/O control with the digital I/O signals.
UC-7408 embedded computers come pre-installed with either the
open standard Linux OS, or the more common WinCE OS. Software
written for a desktop PC can be easily ported to the UC-7408 platform
by using a common compiler, without needing to modify the code, and
the software you develop for your own applications can be stored in
the UC-7408’s flash memory.
In addition to the standard model, a wide temperature (-40 to
75°C) model of the UC-7408 is available for use in harsh industrial
environments.
