The MCW-211 is an Industrial Ethernet FX/TX Media Converter. The MCW-211 convert data between Ethernet 10/100 Base-TX and 100 Base-FX. The unit is easy to use and install caused by auto-negotiation of speed and duplex and auto-crossover and auto-polarity on 10 Mbit/s. The media converter is be transparent for large frames (VLAN or QoS). It is also possible to set speed, duplex and flow control via DIP-switches. The FX side supports Far-End-Fault indication. A link fault from either side shall be forwarded to the other side, Link Fault Forwarding. Via DIP-switches it is possible to control if both sides or just one (either) side supports LFF. MCW-211 has a wide DC power input range with polarity protection and redundant power from dual sources. With extended temperature range supported as standard the MCW-211 is designed to be used the harshest environments.
