CMG-6T

You will need access to a PC with a 9-pin RS232 port, and a 12 V

power source.

1. Install Scream! on your PC and run it.

2. Connect the GPS receiver to the CMG-DM24 using the brown

cable supplied with the digitiser. Position the GPS receiver 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.

3. Connect the grey data cable between the CMG-6T and the

SENSOR A .connector on the digitiser.

4. Using the blue/grey combined data/power cable that is included

with the CMG-DM24, connect the digitiser to the PC's serial port
and then to a 12V power supply.

The instrument is now fully operational, and will already be

producing data.

5. After a few seconds you should see the digitizer 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.

If this does not happen, check all connections, and ensure the
power supply is providing the correct voltage and current.
