Communication Connections; 100Basefx Ethernet Port Connection - Weidmuller IE-MC-VL Series Hardware Installation Manual

ATTENTION

Communication Connections

IE-MC-VL models have one 10/100BaseT(X) Ethernet port, and one
100BaseFX (SC or ST type connector) fiber port.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the Media Converter's front
panel are used to connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

100BaseFX Ethernet Port Connection

The concept behind the SC port and cable is quite straightforward.
Suppose you are connecting devices I and II. Contrary to electrical
signals, optical signals do not require a circuit in order to transmit
data. Consequently, one of the optical lines is used to transmit data
from device I to device II, and the other optical line is used transmit
Before connecting the device to the DC power
inputs, make sure the DC power source voltage is
stable.
