Legacy Support for MIP/LDV and LNS/VNI/OpenLNS
For the support of MIP/LDV and LNS/VNI/OpenLNS applications like LonMakerTM, a NIC Legacy Driver is installed along with the NIC software package. The driver is also needed for MNI support, see Chapter 6. You should see a LOYTEC icon in the system tray of your Windows task bar. If no LOYTEC icon appears in the system tray, please select ‘NIC Legacy Driver’ in the section ‘LOYTEC Network Interfaces’ of your Windows start menu.
Note! In Windows Vista/2008, Windows 7/2008R2, and Windows 8/2012, the LOYTEC systray icon will be hidden, as soon as the Legacy Driver is started as a Service, since no graphical user interface is allowed for services in these Windows Versions. In this case, all settings must be done in the LConfig tool (see Chapter 3), which can still be started from the Windows start menu.
To configure the NIC Legacy Support, right-click on the LOYTEC systray icon as shown in Figure 30.

All found LOYTEC network interfaces are shown at the top of the menu. The selected transceiver for each network interface is displayed in parentheses. By selecting ‘Rescan Devices’ you can search for new network interfaces. To change the transceiver of a network interface, select the corresponding menu item. This will invoke the transceiver selection dialog. Please refer to Chapter 4 for more information on transceiver selection.
When starting a MIP/LDV or LNS/VNI/OpenLNS application, all LOYTEC network interfaces should appear in the network interface dialog of the application. Figure 31 shows the corresponding dialog for LonMakerTM as an example for an LNS/VNI/OpenLNS application. Figure 32 shows the dialog for NLUtilTM Node Utility as an example for a MIP/LDV application.
Note! LNS applications require OpenLDVTM Version 3.4 or higher to work correctly with LOYTEC Network Interfaces.
For network interfaces that support MNI (Chapter 6), a certain number of MNI devices, as configured in the LConfig tool, see Section 3.1, will be displayed for the network interface. By default, two MNI devices will be available, e.g. ‘NIC_USB100_1_000’ and ‘NIC_USB100_1_001_LDV’. Observe that the device names for MIP/LDV applications have an ‘LDV’ tag at the end, whereas the device names for LNS/VNI/OpenLNS do not. Make sure you select the appropriate device.
Generally it is recommended to always use the same MNI device for all LNS/VNI/OpenLNS applications (e.g. ‘NIC_USB100_1_000’). An exception is the NIC852, where a unique MNI device must be used for each database opened simultaneously (e.g. ‘NIC_852_1_000’ for the first and ‘NIC_852_1_001’ for the second database). For this purpose, you must of course reserve more than one LNS/VNI/OpenLNS device in the LConfig tool, see Section 3.1.

After the application has started, the LOYTEC systray icon should be rendered in color, indicating that the connection between the legacy application and the LOYTEC network interface is active. When the mouse cursor is moved over the systray icon, the legacy application state (‘<n> active’ or ‘no activity’) as well as all errors that might have occurred are displayed as depicted in Figure 33.

In case of errors, run the LConfig tool (see Chapter 3) and test the corresponding network interface. The LConfig tool can be started by double-clicking the LOYTEC systray icon or selecting ‘LConfig…’ in the system tray menu (Figure 30).
