Networking

Scream includes extensive support for TCP/IP and UDP/IP networks. It is designed to be effectively network-transparent, so users can contact and configure digitizers at remote sites as easily as those directly connected to the computer.

A network summary window monitors the status of data streams, mass positions, and GPS timing for every instrument. Scream! can also send e-mails automatically to alert station operators when problems occur.

The Scream! network protocol is supported by Earthworm’s scream2ew extension module, which is part of the standard distribution.
