As a switch the MCI-422 is an industrial 4-port 10/100 Mbit/s Fast Ethernet Fibre Switch, incorporating 3.2 Gbit/s switching fabric with non-blocking store and forward technology. In converter mode it is a 2-channel 10/100 TX to 100 FX media converter, featuring remote Link Loss Forwarding technology. The unit is simply configured as either device using a DIP switch. The LFF is also set up in this way. The MCI-422 has dual redundant power inputs with wide DC range 10 ~ 60 V, it also has an alarm relay to trigger an alarm signal for port or power events. Two versions are available for either single mode or multimode fibres. The MM version for multimode fibres up to 2KM and the SM version for single mode fibre t
