This document introduces the RM-3xx.xx system, which is a multipurpose core system that can be used for various control and monitoring applications like SSR, NDB, VOR, TACAN, DF, markers, and indicators. It has a RAMA controller at its core that is based on an ARM9 processor and can take on various roles like a PLC controller, serial port server, protocol converter, and GPRS modem. The RAMA controller runs Linux and has features like Ethernet, serial ports, digital and analog inputs/outputs, flash storage, and low power consumption. It provides a flexible platform for remote monitoring and control applications.
