Multipurpose programmable module NDAS-RT

NDAS-RT is a multipurpose programmable module designed for seismic monitoring and real-time seismic safety. 

It can operate as a node of the Seiscomp 3 networks. The module is specifically designed to expand the networking capabilities of digital seismic sensors produced by R-Sensors LLC. However, it can be used as a standalone device. 

The basic features of NDAS-RT include support for CME-ND and MTSS-ND series digital seismometers and accelerometers, Seedlink protocol over Ethernet, 6 auxiliary ADC channels and two groups of relay contacts to control external devices. 

Modifications are available with additional network interfaces including RS-485, CAN, Wi-Fi, GSM / 3G / LTE, Bluetooth, etc. 

An open platform running Linux gives you the freedom to adapt the NDAS-RT software to the specific tasks of filtering, processing and transmitting the seismic data.
