Tutorials > Networked data acquisition tutorial

In this section we can see procedures to control the Acquisition from the Client:

•	Creating a Display on the CLIENT

•	Storing Data on the MU(s)

•	Transfer Stored Data to the Client

•	NET menu option

Creating a Display on Client

Before you begin storing, you may want to set up the local display. In previous steps you may have configured the display of one or more MU’s, but you probably want to see data here, too!

You certainly know how to do this. Use the Overview, Scope, Recorder (et al) buttons at the top of your own screen here on the Client to create displays with any combination of channels from any and all MU’s!

As mentioned previously, all MU’s must have a SYNC method in place in order to ensure these three things:

•	truly synchronized data files from multiple MU’s

•	ability to display channels from more than one MU on the client

•	ability to create math channels on the client with channels from more than one MU

Note that the CHANNELS list is now showing channels with the "name" of the MU that they come from automatically. This is so that you know the source of every channel in an easy and convenient way.
In our example, the name of the MU, "WEBSTER" is added in front of the transfer channels from that MU by default, as you can see on the right picture.

The channels from each MU will be shown this way automatically. This is the only thing that differs from setting up a screen in the standalone mode of DEWESoft.

Channel list

Consult the complete Display settings tutorial if you need further help in setting up a display.

Storing Data on the MU(s)

With the client and MU properly configured, we can now store data. Just click Store in the toolbar in the normal way.

Storing data

You can see from the "event log" above that we started storing, added a notice event by clicking the spacebar during the recording and that we stopped it.

Transfer Stored Data to the Client

As soon as storing is stopped, an important button appears automatically, called Transfer:

Transfer button

Please click it, and the data file(s) from all MU(s) that we just used, will be downloaded to the client for you. A "transfer box" appears to show the progress, and eventual completion of the download:

Progress of the download

In this case we only had one MU, so only one file needed to be downloaded.

NET menu option

Click the NET menu option to see the list of options:

NET menu options

Notice from the menu that you have several useful capabilities:

•	Connect / Disconnect from measurement units - connect to all MU’s / releases the connection

•	Close DEWESoft on measurement units - closes the DEWESoft application on all MU’s

•	Measure transfer speed - measuring the bandwidth (transfer speed) between the MU(s) and this client

•	Show status - (displays window with current status of all measurement units)

•	Reboot measurement units - reboots the MU computers (useful if they have crashed or hung up)

•	Shut down measurement units - shuts them MUs (requires ACPI power system on the MU’s)

•	Wakeup measurement units - starts MUs (requires 'Wake-up on LAN' option enabled on the MU's)
