Moxa Technologies Media Converter User Manual

Media Converter User's Guide
Second Edition, June 2008
1. Overview
MOXA 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 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 adaptor or
USB port on the hosting device (e.g., PC or NB). The option of using
USB port power, which is unique to ME51 for products of this type,
offers greater flexibility when deploying ME51 in the field.
