PRODUCT OVERVIEW
ETX-401 is a 4-port Ethernet repeater which is intended to extend two Ethernet Train Backbone (ETB) links for another 100 meters. This facilitates the use of only one Ethernet Train Backbone Node (ETBN) for a group of vehicles where the total lenght of the ETB segment would exceed 100 meters.
An optional power supply redundancy allows uninterrupted operation in the event of the failure of one power supply. Moreover, such a failure is signalled by closing a relay contact, which can be used for remote diagnostics.
If the ETX-401 is powerless, or in case of internal failure, a bypass relay automatically bridges both ETB links preventing the interruption of the ETB links.
