Chapter 1 Introduction

Welcome to Moxa UC-7408, a data acquisition embedded computer that features 8

RS-232/422/485 serial ports, dual 10/100 Mbps Ethernet ports, a PCMCIA interface for wireless

LAN communication, 8 digital inputs and 8 digital outputs, and CompactFlash for mass storage

disk expansion.

The digital I/O feature of UC-7408 provides users with the convenience of connecting digital

devices to a front-end embedded computer. UC-7408 can be used for on/off event handling by

reading the state change of the digital input signal. Output signals from external digital devices can

be imported into UC-7408’s digital input channels, and then UC-7408 can be programmed to take

immediate action when it detects a change in the signal state. The digital output channels on

UC-7408 can connect to devices and trigger digital output signals to control external digital

devices. The digital I/O feature allows Moxa UC-7408 to support data acquisition and protocol

conversion via the RS-232/422/485 serial ports, as well as simple I/O control with the digital I/O

signal.
