Installing DLN Setup Package
DLN setup package works with DLN-series adapters in MS Windows OS. DLN setup package includes the drivers for the DLN adapters and the software to operate with them. DLN setup package also includes libraries, source files, documentation and demo applications.
To install the software for the DLN-series adapters on MS Windows, download and launch the latest DLN setup package from the Downloads section of the www.dlnware.com web site.
If the software has been previously installed, the installation wizard will ask your permission to uninstall it and continue upgrade.
When the installation begins, the “License Agreement” screen will appear.
Upon reading the license agreement, in case you agree with the conditions, press the I Agree button to continue the installation.
The “Choose Install Location” screen will be displayed.
After you select the destination folder, click the Next button. You will be asked to choose the desired interface type.
By default the Server Based Interface is selected and recommended in most cases. By using the Direct Interface you can reach higher bandwidth when you transfer a large amount of data, but it only allows one application at the time communicate with the DLN adapter. For additional information refer to the Interface Types section.
When you click the Next button, you will see the “Choose Components” screen.
The Core component contains the driver and libraries that are necessary to interface the DLN-series adapters. You can’t unselect it, because it is used by all other parts.
The Binaries section contains the precompiled and ready to use applications.
The Redistributable section contains the drivers and libraries that you may need to build a setup for your DLN-based application.
The Examples section contains source code for demo applications in various programming languages. You can expand this section and choose demos in specific languages. Some of the examples are not available for the Direct Interface mode. For additional information refer to the Interface Types section.
The Documentation section contains this user manual, schematics and API manuals in various programming languages.
Click the Install button to proceed with the installation of the components that you have chosen.
Interface Types
You can either interface the DLN series adapters directly or through the DLN server application. With direct interface you can reach higher bandwidth when you transfer a large amount of data, but it only allows for one at a time application to communicate with the adapter.
Direct Interface
Through direct interface your application directly communicates with the DLN series adapter. The library and driver help to establish this connection, but don’t route your requests.
Benefits of the direct interface:
The communication is faster than that of the server-based interface. This can be noticeable during the transfer of large amounts of data. In accordance to our measurement, during SPI transfer at high frequencies (above 10 MHz), the bandwidth became twice as fast.
Server-Based Interface
In server-based interface your application connects to the DLN server by TCP/IP and the server routes your requests to the appropriate adapter.
Benefits of the server-based interface:
Several applications can communicate with the same adapter simultaneously.
The DLN-series adapter (together with the DLN server) can be connected to a remote PC (even if one is located at another part of the world). All the communication is done through TCP/IP.
Single application can manage multiple adapters that are connected to different computers.
