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