Chapter 1 Introduction
Welcome to the Moxa UC-8400 Series of RISC-based communication platforms.
The UC-8410/8416/8418 embedded computer comes with 8 RS-232/422/485 serial ports, 3
Ethernet ports, 4 digital input channels, 4 digital output channels, (12 digital input channles and 12
digital output channels for UC-8418), 8 10/100 Mbps switch ports (UC-8416 only), a
CompactFlash socket, and 2 USB 2.0 ports.
The UC-8410/8416/8418 computer uses the Intel XScale IXP435 533 MHz RISC CPU. This
powerful computing engine supports several useful communication functions, but will not generate
too much heat. The built-in 16 MB NORFlash ROM can be used to store the operating system, and
256 MB SDRAM gives you enough memory to run your application software directly on the
UC-8410/8416/8418. Moreover, the 32 MB NAND Flash provides the capacity for data storage.
The UC-8410/8416/8418 computer supports RS-232/422/485 serial ports, digital I/O, and has
three LAN ports, making it ideal as a communication platform for industrial applications that
require network redundancy.
Pre-installed with the Linux 2.6 platform, the UC-8410/8416/8418 provides an open software
operating system for software program development. Software written for a desktop PC can be
easily ported to the UC-8410/8416/8418 platform by using a GNU cross compiler, without needing
to modify the code. This makes the UC-8410/8416/8418 an optimal solution for your industrial
applications with the minimal cost and effort.
In addition to the standard model, a wide temperature version (-40 to 75°C) of the
UC-8410/8416/8418 is also available for use in harsh industrial environments.
