3.2 – Sleep mode
In this mode, the GSBs are not recording seismic data, but the units still have
some basic circuitry active, including the internal radio. The GSBs are in this
mode when they are not inside the record hours window time programmed by
GeoReaper.
3.3 – Disabled mode
The GSBs are not recording data, but they are not in sleep mode. They are in this
mode after one of the following circumstances:
•
The GSB was removed from the rack, and record mode had not been
activated.
•
The GSB was commanded to go to disable mode immediately before the
unit was picked up from the spread. The sequence is explained in
3.4 – Search lost device mode
In this mode, the GSB searches for GPS for 15 minutes to get an accurate position
while showing a SOS LED pattern. It helps to improve its location if the device is
recording or to find a disabled device (lost in the field). To put a device in this
mode, the user should use the LHR+LHV combo to perform the “Find Lost
Device” operation. If you are searching for a lost GSB that has not been deployed
yet, you need to use the scripted channel -1. The devices are programmed to use a
different channel at this time to avoid getting QC data while they are being
transported to the field location.
3.5 – Powered off
In this mode, all GSB circuitry is turned off. It is programmed under the
GeoReaper command, and it is used when the units are getting ready to be
shipped to another location or are to be stored during longer period of times. It
returns to any functional mode after it is placed in the rack or connected to an
external Geospace battery.
