EM-1240-LX User’s Manual Introduction
1-2
Overview
The EM-1240-LX Series of mini RISC-based communication platforms are ideal for your
embedded applications. The EM-1240-LX comes with 4 RS-232/422/485 serial ports and dual
10/100 Mbps Ethernet LAN ports to provide users with a versatile communication platform.
The EM-1240-LX uses the MOXA ART ARM9 RISC CPU. Unlike the X86 CPU, which uses a
CISC design, the ARM9’s RISC design architecture and modern semiconductor technology
provide the EM-1240-LX with a powerful computing engine and communication functions, but
without generating too much heat. The built-in 8 MB NOR Flash ROM and 16 MB SDRAM give
you enough storage capacity and an additional SD socket provides you with flexible storage
expansion to run applications. The dual LAN ports built into the ARM9 make the EM-1240-LX an
ideal communication platform for some of the simple data acquisition and protocol conversion
applications, and the two RS-232/422/485 serial ports allow you to connect a variety of serial
devices.
The pre-installed µClinux operating system provides an open software operating system for
software program development. Software written for desktop PCs is easily ported to the
EM-1240-LX by using a GNU cross complier, so that you will not need to spend time modifying
existing software code. The operating system, device drivers, and your own software can all be
stored in the EM-1240-LX’s Flash memory.
