Güralp Minimus
Minimus - A revolution in miniature!
The diminutive Güralp Minimus is an advanced 'smart' 24-bit seismic digitiser, packed with a host of features that make it the ideal 'plug-and-play' solution for rapid deployments and multi-scale networked arrays.For Earthquake Early Warning applications, the Minimus features include industry standard triggering algorithms (STA/LTA); multi-instrument voting to mitigate false positive alerts; Common Alert Protocol (CAP) for automated emergency warning; plus an ultra-low-latency mode which when used with our GDI protocol means network transmission can be achieved in 40 milli-seconds (network dependent).
Available in 4-channel (Minimus) or 8-channel versions (Minimus+).

Güralp NAM
Versatile seismic network management
The NAM is a stable, robust data hub with unrivalled configurability, ideal for large or complex regional and national arrays and other multi station monitoring solutions.
As a communications hub, the NAM acquires multiple data streams from connected instruments (either local or remote, over serial or IP communications) and acts as both a data store and data transmitter.Additionally, it can deliver real-time protocol conversions to a variety of seismic formats.
For stations where access to GNSS (Global Navigation Satellite Systems) is impractical, the NAM can also operate as a Network Time Protocol (NTP) server, synchronising the remote stations to a local GNSS receiver.
- Stable, robust and flexible for confident long-term deployments with total autonomy
- Designed to act as a data concentrator in seismic networks, capable of acquiring data from up to 500 instruments at 100 sps
- Control using either Web interface or the console accessed via video, serial or SSH
- Multi-user Linux operating system
- Ethernet LAN (10/10 0/10 0 0 0Base-T) 802.1q tagged VLAN support
- Full TCP/IP support with PPP
- LCD display for status information
- 8/16/24 RS-232 port expansion options
