Chapter 1 Introduction
Thank you for purchasing the Moxa EM-1240 Embedded Module. The product’s features include
4 software-selectable RS-232/422/485 serial ports, two 10/100 Mbps Ethernet ports, and SD
signals for external SD socket connection based on the Moxa ARM9 32-bit 192 MHz
communication processor. These features make the EM-1240 ideal for the core module of an
industrial embedded system design.
The EM-1240 Development Kit, which is designed for system and software program development
at the system evaluation stage, is also available. The kit combines the EM-1240 and EM-1240-DK,
which is the carrier board used to evaluate the EM-1240. The EM-1240’s pre-installed
ready-to-run μClinux Kernel 2.6 makes it easy to develop programs for any application.
In this manual, we introduce the hardware features and functions of the EM-1240 Embedded
Module and the EM-1240 Development Kit. After a brief introduction of the hardware features,
the manual focuses on installation and hardware configuration with device interfaces.
