• Extend english version

Introduction

This is the documentation for the APIs that implement the Nanometrics Protocols. They have been developed for interacting with NaqsServer and DataServer.

The Nanometrics NaqsServer provides online access to time-series, serial data, triggers, and state-of-health data via TCP subscription.

The Nanometrics DataServer provides local and remote access to nanometrics, serial, and state-of-health data via TCP/IP.

The library offers APIs to:

• interact with NaqsServer that uses version 1.4 of the Private Data Stream Protocol
• interact with DataServer that uses version 1.0 of the Nanometrics Data Access Protocol
• manage Nanometrics data formats
• request, receive and interpret online and offline data

moreover, you can use them to develop software to:

• analyze data in realtime (waveforms, triggers, ...)
• retrieve and convert on the fly data into the mini-SEED records (optional)
• feed SeedLink server (optional)
• feed Earthworm system (optional)

Dependencies

An optional library is needed to allow libnmxp to save mini-SEED records:

• libmseed: http://www.iris.edu/manuals/
  The Mini-SEED library. A C library framework for manipulating and managing SEED data records.

Installation

nmxp library has been developed using GNU Build Tools (automake, autoconf and configure script) taking in account the POSIX Cross-Platform aspects. So you should be able to compile and install it everywhere you can launch the following commands:

./configure

make

make install

Please, refer to the file README and INSTALL for more details.

Tools

Inside the distribution is available a tool which is a client that interact with NaqsServer and DataServer.

nmxptool:

• implements the Nanometrics Private Data Stream Protocol 1.4 and permits to retrieve data in near-realtime.
  
• implements the Nanometrics Data Access Protocol 1.0 and permits to retrieve backward data.
  Please, refer to the README file or help nmxptool --help.
