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 and Antelope's guralp2orb extension modules. Both modules are part of the standard distribution.
