Generation
in Data
Acquisition
Finally, a portable instrument that is truly
compact and self-contained. Regardless of
the application, you will appreciate how
little equipment you will actually need to
carry to the field. No laptop, PDA or
breakout box, just a seismometer, cable,
Taurus and battery.
A complete seismograph you
can hold in your
hand
The Taurus Digital Seismograph is a revolution in performance, capability and packaging in field portable seismographs. This small and lightweight hand-held
instrument can directly interface with almost any sensor,
record continuous data for over 800 days, and operate
using a mere 750 mW. Taurus combines all the attributes
of a stand-alone recorder with the benefits of Internet
and wireless communication capabilities, and includes a
high resolution 24-bit ADC, a precision GPS clock, and
internal removable storage options with
1 to 40 Gbyte capacities. An integrated colour graphics
display and a five-button keypad provide instant access to
real-time or recorded data.

Benefits
➤ Excellent quality data with 24-bit resolution and precise
GPS timing
➤ Hand-held,all-in-one seismograph
➤ Long term deployments with over 800 day recording capacity
➤ Quick and convenient data retrieval using internal
hot-swap media
➤ Real-time data streaming for network applications
➤ Real-time,historic and calibration data review at-a-glance
➤ Data output directly in industry-standard formats
A high dynamic range is
essential in modern broadband data acquisition.
Taurus is well-equipped with
a Nanometrics proprietary
sigma-delta digitiser providing 24-bits of resolution and
a dynamic range of 138 dB.
Sampling is simultaneous on
all channels and timing accuracy is sub millisecond with
the GPS locked.

TAURUS: Class-leading dyna
➤ Quick and convenient data retrieval using internal hot swap storage media
Compact Flash and 1.8” ATA hard disk drive slots are standard on every unit. A watertight access door affords quick and easy access for
fast media exchange in the field without interruption to data acquisition. Memory options can be selected as appropriate for environmental conditions and Compact Flash media can be purchased directly from local suppliers.
➤ Minimal power,maximum data availability
Taurus has an impressively low power consumption of just 750 mW in a typical portable system configuration acquiring 3-channels at
100 sps. This significantly reduces the size of the solar panels and batteries required at any site. Users will appreciate the importance of
low power consumption and increased reliability – it is not uncommon for the Taurus to operate continuously from a 10 Ah battery and
18 W solar panel.
➤ Integrated display provides clear concise feedback
Every Taurus includes a large colour graphics LCD display and a five-button keypad which provides direct access to various acquisition,
monitoring, configuration and instrument status web pages. There is no guesswork or interpretation of LED sequences – just concise instrument status messages and graphics.
➤ Familiar web browser interface for local or remote operation
No special software is required to configure the Taurus or to display real-time waveform or state-of-health information. A familiar web
browser provides onboard and remote access to the many interactive web pages which make up the Taurus interface. Real-time and historic data, GPS status, instrument configuration and field procedures are all richly presented on the large colour graphics display. Many of
the html pages can be translated into other languages or edited to include customer workflow requirements for configuration, monitoring and data retrieval.
➤ Connects directly to all modern seismometers with single cable
Taurus can interface directly with any modern broadband or short period sensor without the need for external breakout boxes or power
supplies. Hardware and software gain are user-configurable via the browser interface, as are the sensor control lines for mass centering,
cal enable, and lock/unlock. Taurus will monitor the sensor mass position and center the masses as required, facilitating single visit deployments of broadband sensors. This is most important immediately after installation while the sensor is acclimatizing.

➤ Data output in industry-standard formats
In addition to waveform data,Taurus records the entire configuration history, all log file
entries and status information data in a single project file or Store. Data is organized to
facilitate the rapid review and retrieval of waveform, configuration and log file information. The Store contents can be reviewed using a web browser and data can be directly accessed in a number of international formats including miniSEED, sorted
miniSEED, ASCII, SEISAN and SEG-Y.
➤ Real-time data streaming for network applications
Taurus includes a wide range of physical interfaces and software protocols to
support continuous real-time data streaming. Where network connections
exist, real-time data streaming is available via UDP/IP multicast and http over
10/100Base-T Ethernet or the serial data port (SLIP). Optionally,Taurus
data can be accessed through dial-up or wireless internet connections.
➤ New capabilities readily incorporated into Linux & Java
based architecture
Today’s portable seismograph must operate unattended for long periods in remote areas, and seamlessly integrate with communications
technologies such as VSAT, wireless and the Internet. To meet these
challenges the Taurus architecture combines the versatility of the Linux
operating system with modern Java applications while interconnecting
with standard IP protocols over either Ethernet or serial interfaces. A
winning combination designed to keep Taurus on the cutting edge for
years to come.
TRIDENT Digitiser
TheTrident 305 is a low-power, standalone,
3-channel, 24-bit analog-digital converter (digitiser)
whose performance specifications are identical to the
internalTaurus digitiser.
➤ Add-on expansion digitisers
The Taurus supports 3-channel add-on Trident 305 digitisers expanding the total
number of channels supported by a single Taurus from 3 to 6 or 9 channels. The
Trident 305 settings (ex. gain, input impedance…) can be configured independently of the Taurus internal digitiser while making use of the Taurus for communications, GPS timing, data storage and power. Trident 305 connects to the Taurus
via a simple twisted pair NMXbus cable which can be up to hundreds of meters
in length. A Taurus/Trident 305 combination makes an excellent 6 or 9 channel
system.
APOLLO Project
➤ Data management,simplified
Apollo PROJECT is a server application which manages the time consuming and
repetitive task of downloading large data sets from multiple Taurus recorders.
The user defines the type of project: archive, one-time data request, trigger or
controlled source. Apollo PROJECT locates the data, downloads the requested
time series, combines the data into network files and outputs the data in the format of choice. There is no more convenient way to simultaneously manage large
data sets from multiple Taurus instruments.
