Chapter 1 Introduction
The Moxa EM-1220-LX is a mini RISC-based ready-to-run embedded module that features dual
10/100 Mbps Ethernet ports and two RS-232/422/485 serial ports in a µClinux ARM9 module. In
addition, the EM-1220-LX supports an external SD socket for installing an SD memory card for
storage expansion, and offers high performance communication and unlimited storage in a super
compact, palm-sized module. The EM-1220-LX is an ideal solution for embedded applications
that use a lot of memory, and that must be housed in a small space without sacrificing
performance.
