can safely be removed.
Red – removable media is mounted,
in write mode, DO NOT remove.
Installing Removable Media
●
Always power down the Taurus Processor before adding,
removing or changing the media (CF/IDE).
You may lose data if the
media is removed while the
Taurus Processor is running.
You may lose data if the
media is not inserted before
the buffer fills-up.
Installing Removable Media…
1.
Lift the plastic lever on the
media door.
2.
Twist the door knob counter
clockwise to the unlocked
position (lever is vertical).
3.
Flip the lever flat against the
door, allowing the handle to
push against the chassis and
causing the door to pop
free/open.
Installing Removable Media…
●
●
●
Make sure Media Access LED is
green OR the power is off.
Gently pull on the end of the
CF/IDE to remove it.
Gently insert the replacement
CF/IDE.
Inserting Removable Media…
●
●
●
Place and push the media door
in place.
Twist the knob clockwise to
the locked position
(horizontal).
Flip the black plastic lever
down as to lie flat against the
door as shown.
Powering Up
●
Basic Steps:
1.
Connect the GPS, sensor and ethernet cables (if applicable).
2.
Connect the power cable (9-36 V DC).
3.
Wait for the Taurus processor to boot up (~1 minute).

LCD will be off, Unit Status LEDs will show status.
4.
Once the Unit Status LEDs are blinking green or orange, you may start the
GUI.
5.
Press the center button (Enter key) for about 2 seconds.

Starts web browser GUI, and LCD (~1-2 minutes).
Powering Down
●
Do not just disconnect the power cable!
●
Basic Steps:
1.
Go to Shutdown page from the web browser’s drop down menu.
2.
Select the Shutdown option.
3.
Wait for all status LEDs to be turned off to indicate the processor has been
shut down.
4.
Disconnect the Taurus power cable.
Accessing the Taurus
●
●
From external web browser:
1.
Connect the Taurus using the ethernet cable (15228) to your LAN or
computer directly.
2.
Open your browser and go to the Taurus URL: http://Taurus.IP.Address.
The IP address of the Taurus is shown on the Current Status Page
of the internal browser.

Software Introduction
●
First true internet device for the seismic market.
●
Web server based data acquisition system.
●
“Thin client” approach, no special software required to interact
with the Taurus.
●
A networked Taurus can be accessed from anywhere in the world!
●
Linux based operating system.
Modes of Operation
●
Two modes of operation: buffered or communications.
●
Buffered:
●

Stand alone, unattended continuous data recording, no comms.

Lowest power consumption.

ADC/DSP acquires data into internal flash memory buffer.

Linux Processor is powered on to write to removable media when buffer is
near full capacity. Processor powers back down until next write event.
Communications:

Continuous write to removable media.

Taurus and data are accessible via ethernet or serial ports.

Streaming to data acquisition server capable.

Data Organization
●
Data types: waveform, SOH, configuration, etc.
●
Next generation NAQS: STORE system.
●
Open database system, with STORE objects.
●
STORE object combines waveform, SOH and config data for a
given time period – all in a single file.
●
Waveform data is stored in 1st difference Steim format.
●
SOH & config data are stored in XML/RDF.
●
STORE uses URL as primary index.
●
Data is self describing (where, when, whom).
User Interface
●
On-board colour LCD.
●
5-button navigation.
●
Access to acquisition system via web browser:

Real-time waveform data.

SOH data.

Configuration information.

Calibration commands.
Taurus Configuration
●
All data types are recorded by default.
●
Minimal configuration required to get data recording started.
●
Units can be configured individually.
●
Units can have its configuration uploaded as an XML file.
●
All configuration changes are logged to the STORE for
traceability.
Accessing real-time data
●
2 protocols: UDP/IP or HTTP.
●
UDP/IP:

●
Broadcasts data packets to an unicast or multicast IP address.
HTTP:

Uses a TCP/IP socket and HTTP between Taurus and receiving software.

HTTP allows POST and GET commands to/from Taurus.

HTTP is implemented in all web servers/browsers.
Data Downloading
●
Request for specific data segments via web interface or HTTP
commands.
●
Request for: waveform data, SOH and config.
●
Option to directly extract data into miniSEED.
●
●
All resources available to the web browser can be accessed
directly from customer developed software.
Standard HTTP protocols and URL.
System Security
●
Linux operating system.
●
User and password protection for all IP service access.
●
Accounts and access rights.
●
Full implementation in Taurus Version 2.0
