All of our industrial products are made to be installed in a server rack on a top hat railing. If you combine the SU-302 and INU-100 you can use your serial devices over the TCP/IP network. INU-100 connects USB devices such as the SU-302 in ethernet networks. Serial devices can then be used easily and flexibly in modern industrial environments.
