System ID
The System ID pane gives information about the digitiser and its internal
software, and allows you to change GPS timing parameters.
System Identifier and Serial Number: The digitiser type is identified by
its system identifier and serial number. Every data and status block
generated by the digitiser includes these two fields at the beginning, so
that the block’s origin can be identified. On delivery from the factory,
the system identifier and the serial number are set to the GSL works
order number and the digitiser’s serial number, but you can set either
value to any combination of up to 6 letters A-Z and numbers, such as an
abbreviation of your institution’s name, etc.
Sensor Type: If the sensor attached to the digitiser is a Güralp velocity
sensor, useful seismometer functions (such as sensor locking, centring,
and calibration) may be controlled through the digitiser. The type of
sensor programmed with this option determines which functions will be
available through the Scream! digitiser configuration set-up interface or
through interactive commands. The in-built digitisers are already
programmed to the proper sensor type for Güralp CMG-5U uniaxial
sensors.
