  36. Status LEDs • 4 status LEDs • 2 for Unit Status • 1 for Ethernet connection / activity • 1 for Media Access status Unit Status Unit Status Ethernet Status Media Status

  37. Status LEDs… Unit Status LED: Off – Digitiser is powered off. Solid Red – Digitiser is booting up. Normal conditions to capture data: Fast Blinking Green – GUI is starting up. Slow Blinking Green – normal operation. Fast Blinking Orange – power up, unit boot up. Warning conditions: Slow Blinking Orange after power up – media door open, low battery, poor GPS timing.

  38. Status LEDs… Critical Fault Status: Fast Blinking Red – fault preventing normal operation. • Disconnected GPS • Missing media • Hardware problem • Software problem

  39. Status LEDs… • Ethernet Status LED Off – processor is powered down. Orange – processor is booting. Blinking Green – network configured, carrier detected. Blinking Orange – network is not configured. Blinking Red – network is configured, no carrier detected.

  40. Status LEDs… • Media Access Status LED Off – media door closed or pressed in. Green – removable media (CF/IDE) can safely be removed. Red – removable media is mounted, in write mode, DO NOT remove.

  41. 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.

  42. Installing Removable Media… • Lift the plastic lever on the media door. • Twist the door knob counter clockwise to the unlocked position (lever is vertical). • Flip the lever flat against the door, allowing the handle to push against the chassis and causing the door to pop free/open.

  43. 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.

  44. 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.

  45. Powering Up • Basic Steps: • Connect the GPS, sensor and ethernet cables (if applicable). • Connect the power cable (9-36 V DC). • Wait for the Taurus processor to boot up (~1 minute). • LCD will be off, Unit Status LEDs will show status. • Once the Unit Status LEDs are blinking green or orange, you may start the GUI. • Press the center button (Enter key) for about 2 seconds. • Starts web browser GUI, and LCD (~1-2 minutes).

  46. Powering Down • Do not just disconnect the power cable! • Basic Steps: • Go to Shutdown page from the web browser’s drop down menu. • Select the Shutdown option. • Wait for all status LEDs to be turned off to indicate the processor has been shut down. • Disconnect the Taurus power cable.

  47. Accessing the Taurus • From external web browser: • Connect the Taurus using the ethernet cable (15228) to your LAN or computer directly. • 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.

  48. Software Overview • Software Introduction • Software Modules • Modes of Operation • Data Organization • User Interface • Taurus Configuration • Real-time Data Access • Data Downloading • Software Uploading • System Security

  49. 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.

  50. 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.
