1. Overview
MOXA ME51 Media Converter is a standalone physical layer
device that converts between 10/100BaseT(X) and
100BaseFX segments of the same network. The converter
supports Link Fault Pass-through (LFP) for easily tracing
network link failures, and the LFP function enhances the
integrity and conformity of TP-Fiber linking to make the
network easier to maintain. ME51 is powered by an external
power adapter or USB port on the hosting device (e.g., PC
or NB).
