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.
