    Compared to the RS-485 network, these Ethernet network hubs are already in existence for system network. Therefore, the RS-232 devices can find the closest hub and link to the central computer with the help of the I-7540D. The Ethernet network is extremely popular and already existing for most applications, hence, this approach is a very successful.
