Page 6: Functional Description
Table 10. When used to support an optic fibre link in a class A bus configuration, one of the DNP 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 10b. Man-1572 DNP-R-2F/FC-K... - Page 7 (RS-485). The INS modules are transparent to the CIE protocols, only routing and analysing the data structure but not the content. The maximum standard transmission rate supported on the CIE ports (A1 and A2) is 115.2 kbit/s for RS-485. (Higher transmission rates are possible with OEM support). Man-1572 DNP-R-2F/FC-K...

Page 15: Field Applications
This application is useful for the following: converting a radial system to a redundant ring on the existing fibre introducing a temporary solution when a single fibre fails on a link.

With both sides grounded, an unwanted path for circulating currents is introduced. This single point grounding is displayed in Figure 7.
