• Quit will terminate DtUsb, which will mean that the logger's TCP/IP services will no longer be available. This
should normally only be used if you wish to use the direct "COM port" interface to the logger, rather than the
TCP/IP interface.
• Hide will close the GUI, but DtUsb will keep running. Closing the window with the red X button will do the same
thing.
• Apply will apply any changes you have made on the Configuration tab.
 Loggers Screen
Figure 74: Main DtUsb screen
The Loggers tab shows a list of all connected loggers, along with their IP addresses and the port numbers to use to
access their services.
For the HTTP (web) and FTP services, links are provided which will open a web browser window. The HTTP link will
display the dEX home page, while the FTP link will display the web browser's inbuilt FTP client, allowing you to browse
the logger's file system.
To access the command server (e.g. in DeTransfer) you would create a connection using the indicated IP address and
port number (127.1.1.1 port 7700 in this case). To access the DT80 Modbus server you would enter a similar thing into
your Modbus client application.
Note: the port numbers may not necessarily be the "normal" ones shown in the example. For example, if there is a web or FTP server
running on your PC then DtUsb will automatically assign different port numbers in order to avoid conflicts – for example, port 81 instead
of port 80 for the web interface.
 Configuration Screen
Figure 75: DtUsb Configuration Screen
This screen allows you to select
• whether the dEX home page is automatically launched each time a logger is plugged in
• the base IP address that DtUsb presents to other applications. This would only need to change if there was
some sort of conflict with other software on your computer.
USB Direct Serial Mode
If you wish to use DeTransfer to control the DT80 via a USB connection then it is necessary to shut down DtUsb. Double
click on the purple DtUsb icon in the system tray (or choose DtUsb in the Start menu) to bring up the DtUsb GUI then
select Quit (and then confirm by selecting Yes).
You should now be able to run DeTransfer and create a serial connection by selecting the COM port that has been
assigned to the USB interface. If you don't know the COM port number, you can check by using the Windows device
manager (right click on My Computer, select Manage, then Device Manager, then open the Ports (COM & LPT) item in
the tree and look for an entry called dataTaker USB Serial Port. See Figure 76.
