EM-1240-LX
Quick Installation Guide
Third Edition, June 2008
1. Overview
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 connections, based on the Moxa ARM9 32-bit 192 MHz
communication processor. These features make the EM-1240 ideal for
use as the core module of an industrial embedded system.
In addition, Moxa provides an EM-1240 Development Kit, which is
designed for system and software program development at the system
evaluation stage. The kit includes the EM-1240 embedded computer,
and the EM-1240-DK carrier board, which is used to evaluate the
EM-1240. The EM-1240’s pre-installed, ready-to-run μClinux Kernel
2.6 makes it easy for users to develop programs for any application.

5. Combining Embedded Module with EM-1240-DK
Insert the EM-1240 embedded module vertically onto the Development
Kit board. Note that the pin marked “JP4” on the embedded module
must be matched with the pin marked “JP6” on the Development Kit;
the pin marked “JP3” on the embedded module must be matched with
the pin marked “JP4” on the development kit. Use caution when
combining the boards, since improper handling could damage the
boards’ pins.
