Introduction 

Thank you for purchasing the Moxa IA3341 RISC-based industrial ready-to-run embedded computer. The 
IA3341 is based on the MOXA ART ARM9 industrial processor, and features 2 RS-232/422/485 serial ports, dual 
LANs, 4 digital input channels, and 4 digital output channels. In addition, the IA3341 computer has 2 analog 
input channels and 2 thermocouple channels, making it the ideal solution for a variety of industrial applications, 
such as solar power and environmental monitoring. This manual introduces the IA3341’s hardware. After a 
brief introduction of the hardware features, the manual focuses on installation and configuration.
