The serial communication module (SLM) is a mezzanine module placed on the Main Processing
Module (NUM) and is used for LON, SPA, IEC60870-5-103 and DNP communication.
There are two types of IO connectors: 1) snap-in for plastic fiber cables, and 2) ST/bayonet for
glass fiber cables. The SLM can be equipped with either type or a combination of both, which is
identified by a tag.
Connect the incoming optical fiber to the RX receiver input, and the outgoing optical fiber to the
TX transmitter output. Pay special attention to the instructions concerning handling and
connection of fiber cables.
