Data Flow Mode

SeedLink Streamer Mode (Recommended)

RECOMMENDED MODE - Real-time data transmission using SeedLink with NTP timing.

Use this mode when the Sixaola has a connection to the Internet and data can be streamed to a central SeedLink Server.

In this mode, it is not possible to archive continuous or triggered waveforms to disk. If triggers are activated, only trigger times will be logged to /opt/log/o-trigger.evt. For more details see:

• Triggering
  • Configuration
  • How it works

Confirm that you can connect to the unit locally or remotely using slinktool:

$ slinktool -Q [IP]:[Port]

REQUIREMENTS

• Timing (either NTP or GPS. We recommend NTP whenever possible. The only time to use GPS alone is if you are in remote logging mode or NTP has been blocked by some overzealos network adminstrator.)
• Ethernet

Note

When in SeedLink Streamer Mode, the SeedLink port defaults to 18000.

SeedLink Streamer Mode (With Local Backup)

Same as SeedLink Mode but with 3 days of continuous waveforms saved to disk for Sixaola3 and 7 days for Sixaola4.

Continuous waveforms are saved to disk at /opt/seiscomp/acquisition/archive/waveforms/continuous

(See above fore more details)

CAPS Mode (Premium Feature)– NEW!!!

(Added to the Sixaola December, 2015)

Note

CAPS Mode is a premium feature that requires a License. See Premium: Paid Software Options & Accessories for more details.

Real-time data transmission using gempa GmbH’s CAPS server.

Similar to SeedLink, use this mode when the Sixaola has a connection to the Internet and data can be streamed to a central SeedLink/ CAPS Server.

Read all about CAPS here.

In this mode, it is not possible to archive continuous or triggered waveforms to disk.

Confirm that you can connect to the unit locally or remotely using capstool:

$ capstool -H [IP]:[Port] -Q

REQUIREMENTS

• Timing (either NTP or GPS. We recommend NTP whenever possible. The only time to use GPS alone is if you are in remote logging mode or NTP has been blocked by some overzealos network adminstrator.)
• Ethernet

Note

When in CAPS Mode, the CAPS port defaults to 18002.

CAPS website: [Your Sixaola’s IP]:8080

Local backup: 3 days of continuous waveforms saved to disk for Sixaola3 and 7 days for Sixaola4 /opt/seiscomp/acquisition/archive/caps/

Darien Client Mode (Premium Feature)

Note

Darien Client Mode is a premium feature that requires a License. See Premium: Paid Software Options & Accessories for more details.

Real-time data transmission using an OSOP Zero Config Server.

Use this mode if the Sixaola is installed behind a firewall that is not under your control.

This requires that the OSOP Zero Config server has been installed at your institution. All station configuration is done server-side.

In this mode, it is not possible to archive continuous or triggered waveforms to disk.

REQUIREMENTS

• Timing (either NTP or GPS. We recommend NTP whenever possible. The only time to use GPS alone is if you are in remote logging mode or NTP has been blocked by some overzealos network adminstrator.)
• Ethernet (one-way connectivity)

Note

Solid Blue LED: Connection to remote Zero Config Server established. See LEDs for more details.

For configuration see: Software: Zero config server frontend (Darien Client Mode) Configuration

Data Logger Mode

Use this mode for campaign studies where there is no Internet connection and regular data retrieval is possible. Continuous waveforms are saved to disk at /optUSB/waveforms/continuous/ in SeisComP Data Structure (SDS) format as miniSEED binary files.

If triggers are activated, only trigger times will be logged to /opt/log/otrigger.evt. For more details see:

• Triggering
  • Configuration
  • How it works

REQUIREMENTS

• Timing (either NTP or GPS. We recommend NTP whenever possible. The only time to use GPS alone is if you are in remote logging mode or NTP has been blocked by some overzealos network adminstrator.)

Event Logger Mode

Use this mode for campaign studies where there is no Internet connection and data retrieval cannot happen easily. Only triggered event waveforms are saved to disk at /optUSB/trigger/ as multiplexed miniSEED binary files.

For more details see:

• Triggering
  • Configuration
  • How it works

REQUIREMENTS

• Timing (either NTP or GPS. We recommend NTP whenever possible. The only time to use GPS alone is if you are in remote logging mode or NTP has been blocked by some overzealos network adminstrator.)
