6.8 FIBRE OPTIC BOARD

Figure 23: Fibre optic board

This boar

d provides an interface for communicating with a master station. This communication link can use all

compatible protocols (Courier, IEC 60870-5-103, MODBUS and DNP 3.0). It is a fibre-optic alternative to the metallic

RS485 port presented on the power supply terminal block. The metallic and fibre optic ports are mutually exclusive.

The fibre optic port uses BFOC 2.5 ST connectors.

The board comes in two varieties; one with an IRIG-B input and one without:
