The additional features offered with the DNX R-2F/FC-UG license are accessed by
using the IVIEW application. The license indication LED I/O 3 on the keypad is used to
indicate a licensed/unlicensed state, as in Figure 20.
The DNX R-2F/FC can operate in a mode with two optic fibre interfaces (2F) located on
ports B and C and also in a mode with a single optic fibre interface and an RS-485
interface (FC or CF).
In hybrid mode (FC /CF) the optic fibre interface on the DNX R-2F/FC can be
configured as either port B or C by selecting the correct rotary switch setting as per
Table 11. When used to support an optic fibre link in a class A bus configuration, one
of the
DNX R-2FC modules would require a port swap to support the standard port B to C
connection format around the closed ring. An example of this is illustrated in Figure 3.
