How To

RT130 data is downloaded from the CF cards to .zip files using the NEO program.  The NEO program is included in the PASSOFT software package and can be started from the command line or from the NEO button on EPIC field computers. After the data is downloaded it should be reviewed to make sure that it is complete and two backup copies should be made.
 

The following is the procedure to upgrade the firmware of a RT130. The upgrade is applied to the RT130 from a firmware file which is copied to CF card and inserted to the RT130 before it is powered on.   NOTE: For EPIC RT130 dataloggers, please contact us before changing the firmware, we may not support all versions.  Thank you.   2013-04-02: We are updating to RT130 firmware version 3.4.3.  This update will not be made in the field as it includes reprogramming chips from several boards.  Please contact us for further information.    
1.  Obtain a copy of the new firmware.  EPIC will supply this.
 

 

This page is meant as a quick reference guide for using the Clié program "PFC-130" to load configuration parameters to a RT130. When deploying RT130's in the field, you will be provided an installation worksheet which covers the same steps but with more detail specific to your experiment.

Basic Guide for Loading Parameters to a RT130 from a Clié

1. Open PFC-130, on the Clié

2. Select Work with Configuration

3. Load (Load Configuration Pre-Written or Loaded Config File)

4. Select OK

5. Verify Configuration Name top of screen

6. Send to DAS

7. Select OK

8. Select Done

9. Re-Enter Work with Configuration

10. Select from DAS (Load from DAS)

11. Edit

12. Confirm Experiment Name

Necessary information:

Sensor: sensitivity and passband (velocity transducer) or scaling (accelerometer)

For information on sensor sensitivity and passband, see the Sensor Comparison Chart along with the Sensor Response Plot.

Datalogger: Analog-to-Digital (A/D) conversion factor (aka bit weight) and Gain 

Quanterra model Q330: 419,430 counts/volt, or 2.384 uV/count at a Gain of 1 RefTek model RT130: 629,327 counts/volt, or 1.58997 uV/count at a Gain of 1

 

Example: Counts to Ground Velocity Conversion within the Passband

 

Hard drives and disk space Drives and partitions

EarthScope EPIC prepared laptops all come with a separate partition for user and experiment data that can be accessed at /data

EPIC linux laptops (PCs) come with two hard drives.  On each drive is a complete, tested installation of Fedora linux and a current version of PASSOFT. Each drive is bootable and provides a redundant system. On each drive space is allocated for data and is RAIDed together as the /data directory accessible from either installation.

If you are having a problem and want to try using the backup installation, start tapping the Escape key after the BIOS has finished loading in order to see the GRUB menu.  Then select one of the installations of Fedora to boot into it.  If you saved your data in /data, you will still have access when booted from the backup installation.

This page provides instructions for downloading Balers using the EzBaler program and reviewing the State of Health (SOH) data using PQL. EzBaler is the best option for downloading data from multiple Balers at one time. Known problems are: it will sometimes fail to connect to a Baler (just try again) and it will hang up if it encounters corrupted data.  These instructions are written specifically for use with a PASSCAL MacBook field computer, but in general apply to other platforms as well.

The data downloading is in two parts.  The first part is downloading the SOH data which contains the low sample rate seismic data and systems data to be used for doing field Quality Assurance (QA) for the station.  The second part is downloading all of the seismic data for archiving.
