IA260-261-262 EM-2260 LX User’s Manual Introduction
Overview
The IA260/IA261/IA262/EM-2260 embedded computers, which are designed for industrial
automation applications, feature 2 or 4 RS-232/422/485 serial ports, 2 CAN bus ports (only for the
IA262), dual Ethernet ports, 8 digital input channels, 8 digital output channels, VGA output and
CF socket. The computers come in a compact, IP30 protected, industrial-strength rugged chassis.
The DIN-Rail vertical form factor makes it easy to install the IA260/IA261/IA262 embedded
computers in small cabinets. This space-saving feature also facilitates easy wiring, and makes the
IA260/IA261/IA262/EM-2260 the best choice as front-end embedded controllers for industrial
applications.
The IA260/IA261/IA262/EM-2260 computers use a Ciruus Logic 199 Mhz RISC CPU. Unlike the
X86 CPU, which uses a CISC design, the RISC architecture and modern semiconductor
technology provide these embedded computers with a powerful computing engine and
communication functions, without generating excessive heat. A 32 MB NOR Flash ROM and a
128 MB SDRAM give you enough memory to install your application software directly on the
embedded computer. In addition, dual LAN ports are built right into the RISC CPU. This network
capability, in combination with the ability to control serial devices, makes the
IA260/IA261/IA262/EM-2260 ideal communication platforms for data acquisition and industrial
control applications.
The IA260/IA261/IA262/EM-2260’s pre-installed Linux operating system (OS) provides an open
software operating system for your software program development. Software written for desktop
PCs can be easily ported to the computer with a GNU cross compiler, without modifying the
source code. The OS, device drivers (e.g., serial and buzzer control), and your own applications,
can all be stored in the NOR Flash memory.
The IA260/IA261/IA262-LX also supports a VGA output.
Software Architecture
The Linux operating system that is pre-installed on the IA260/IA261/IA262/EM-2260 follows the
standard Linux architecture, making it easy to accept programs that follow the POSIX standard.
Program porting is done with the GNU Tool Chain provided by Moxa. In addition to Standard
POSIX APIs, device drivers for the CF storage, buzzer and Network controls, and UART are also
included in the Linux OS.
