Test installation
This section gives an overview of how to set up a 6TD and begin recording
data. We recommend that you set up a test instrument in your office or
laboratory as a “dry run” to gain a basic understanding of the system and to
check that it is functioning as expected.
This test installation will use the instrument's default settings. Data will be
received using Güralp Systems' Scream! software, available from the website
You will need access to a PC with a nine-pin RS232 port, and a 12 V power
source.
1. Install Scream! on your PC and run it.
2. Connect the wire from the breakout box to the 6TD's 19-pin connector.
3. Connect the 6-pin connector on the breakout box to the GPS unit using
the GPS cable. Position the GPS so that it has a good view of the sky.
If you do not have a view of the sky, you can operate the sensor without
a GPS unit, but timing information may be inaccurate.
4. Connect the six-pin data plug on the breakout box to the nine-pin RS232
port on your PC using the serial cable. If your PC does not have a
nine-pin COM port, use an RS232/USB converter. Güralp Systems
recommend converters based on the FTDI chip-set.
5. Use the power cable to connect the ten-pin power plug on the breakout
box to a fused 10 – 28 V power source.
The instrument is now fully operational, and will already be producing
data.
6. After a few seconds you should see the 6TD's digitiser appear under
Network – Local – Com1 in the left-hand panel of Scream!'s main
window. (If your PC has multiple serial ports, it may appear under
some other Com port name.) Soon after, data streams will begin
appearing in the right-hand panel. Streams with higher sample rates
will appear sooner than those with lower sample rates.
