17.6.2.2 Communication ports
The serial communication module (SLM) is used for SPA/IEC 60870-5-103/DNP and
LON communication. This module is a mezzanine module, and can be placed on the
Analog/Digital conversion module (ADM). The serial communication module can
have connectors for two plastic fibre cables (snap-in) or two glass fibre cables (ST,
bayonet) or a combination of plastic and glass fibre. Three different types are available
depending on type of fibre.
The incoming optical fibre is connected to the RX receiver input, and the outgoing
optical fibre to the TX transmitter output. When the fibre optic cables are laid out, pay
special attention to the instructions concerning the handling and connection of the
optical fibres. The module is identified with a number on the label on the module.
