11.In the next window, check that the correct hardware is shown, and click OK to confirm.

12.You can now remove the hard disk from the computer and reinstall it in the DCM if required.

3.3 The DCM as a GCF data source

With a sufficiently fast serial link, you can instruct the DCM to send incoming data directly to a GCF-compatible client. For example, Gü ralp Systems' Scream! software allows you to display and record incoming data, as well as change the settings of attached digitizers. You can do this in addition to recording data on a local hard disk, or you can leave the hard disk uninstalled and operate the DCM entirely over the network link.

This example shows a module communicating with a local PC over a dedicated radio link. You could also use a simple serial cable to connect the DCM to the PC.

1.Connect the DCM to a digitizer or digital sensor.

2.Connect the DATA OUT port to a source of 12 V DC power.
