Extension modules for calibration, noise calculations and data analysis
Diagnostic tools including data integrity checks, at-a-glance GPS and mass position status, and direct access to the digitiser console
Advanced networking facilities
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 digitisers 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.
