EarthData EDR-210
The EDR, made by EARTH DATA
(U.K.), is a digital recording system for stand-alone use, but also for use with communication (e.g. real-time data via SEEDlink).
Adaptor cables
are available for all types of broadband seismometers belonging to the DEPAS pool.
Digitiser SetUp and Control can be done via serial link (manufacturer software).
Additionally, a GFZ-GIPP made Recorder SetUp and Status View Software (including Digitiser Parameters) is available for the use of WIN/DOS. The GFZ User Software also supports
Group SetUp; and the Control functions, as Status View and Configuration File Download, are performed as one-key commands.
Data Retrieval is supported by GFZ User
Software and by a set of disk adaptors cables to connect the hard disk to standard USB-2.0.
