Figure 1 .l SLTA-10 Adapter Node Architecture with Local Host
Two Modes of Operation: SLTA-10 NSI and MIP Modes
The SLTA-10 Adapter provides both the network services interface (NSI mode)
functionality for use with LNS-compliant applications, and network interface
functionality (MIP mode) for use with LonManager API-based applications.
There are two separate firmware images in the SLTA-10 Adapter. The two separate
images have different link layer protocols, different network drivers, different buffer
capacity, and different functionality. The two modes of operation are the SLTA-10
NSI mode and the SLTA-10 MIP mode. The mode of operation is controlled by an
externally accessible DIP switch that is read at power-up.
Table 1.1 illustrates the differences between the SLTA-10 NSI mode, the SLTA-10
MIP mode, and the SLTA/2.
