The Interlink is a TCP/IP client/server-based 16-bit digitizing and transmission system. Data from analog networks, NetDAS field stations and local strong-motion recorders are combined by InterLink and client/server software and presented to clients anywhere on the Internet. Interlink can be used to replace expensive leased analog phone lines with IP data transmission. Interlink offers a turn-key and affordable nodal recording solution for seismic, geophysical and strong motion networks. Interlink runs under Linux or Windows XP.
