Overview

The UC-7408 is a data acquisition embedded computer for embedded applications that features 8 RS-232/422/485 serial ports, 8-ch digital input, 8-ch digital output, dual 10/100 Mbps, PCMCIA interface for wireless LAN communication, and CompactFlash slot for mass storage disk expansion.

In addition to the 8 RS-232/422/485 serial ports, the UC-7408 also has 8 digital input and 8 digital output channels, making it suitable as a data acquisition solution.

The digital I/O feature of the UC-7408 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 in through the UC-7408'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.

Choose a pre-installed 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. All the software you develop for your own applications can be stored in the UC-7408's flash memory.
