NetDAS-32 is a multi-platform high channel count 24-bit data acquisition system (DAS) based on open industry standards such as Ubuntu Linux, TCP/IP, USB and client/server software. The software is multi-platform so runs identically under Microsoft Windows. NetDAS finds application in sensory applications requiring high resolution. Introduced in 2003, NetDAS was the first DAS to run embedded Linux. NetDAS comes bundled with NetDAS Tools software clients including triggering (amplitude, STA/LTA, spectral/OBE, network message and external logic level), formatting, Earthworm client, real-time display and data concentration.

Applications
- Central recorder for large sensory networks
- Local accelerometer array recorder
- Data stream concentrator
- Seismic/earthquake recording, monitoring, logging and data acquisition
- Seismic and strong-motion networks on earthquake fault zones and volcanoes
- Low packet latency for Earthquake Early Warning (EEW)
- Laboratory and sensory data acquisition
- Seismic monitoring of dams, LNG facilities, semiconductor production lines and bridges
