2 Setting up the CD24<br />
This section gives an overview of how to set up a CD24 and begin<br />
recording data. We recommend that you set up a test digitiser in your<br />
office or laboratory as a “dry run” to gain a basic understanding of the<br />
system and to check that it is functioning as expected.<br />
This test installation will use the digitiser's default settings. Data will<br />
be received using <strong>Güralp</strong> <strong>Systems</strong>' Scream! software, available from<br />
the website: www.guralp.com<br />
2.1 Connectors<br />
The CD24's output connectors are located on the lid. The sensor input<br />
is located on the side. The digitiser can be supplied with a number of<br />
options, so not all the connectors may be present on your digitiser.<br />
The input connector is configured to connect directly to one of GSL's<br />
sensors and has all the necessary power and control functions.<br />
All CD24s have a 19-pin mil-spec connector on the lid for connection<br />
to a supplied breakout box with the following connections:<br />
• a 6-pin socket for connecting the supplied GPS unit;<br />
• a 10-pin plug for connecting to a PC's serial interface or a <strong>Güralp</strong><br />
data module..<br />
• a 6-pin mil-spec plug for connecting to a power source.<br />
You may need to attach a suitable connector to the power cable<br />
provided. The CD24 draws a nominal current of 55 mA from a 12 V<br />
supply when in use; thus, using a 12 V, 25 Ah sealed heavy-duty leadacid<br />
battery, you should expect the digitiser to operate for more than a<br />
week without recharging.<br />
The CD24 may also have connectors for the FireWire, Ethernet or<br />
Wi-Fi interfaces.<br />
2.2 Test installation<br />
To test the CD24, you will need access to a PC with a 9-pin serial port<br />
(RS232), a 12 V power source and a working sensor (e.g. CMG-3ESP,<br />
ESPC, 40T or 6T).<br />
Install Scream! on your PC and run it.<br />
