Serial Network
Working as an Ethernet Data Gateway, the ADAM-5000/TCP Series
provides an RS-485 interface to integrate serial devices for various
applications. Adopting by Modbus standard protocol, it solves the
communication problem between different networks and different
devices. Mean while, users can extend their system scope by
integrating up to 32 nodes of ADAM-5511 or other Modbus products,
such as meters, card readers, loadcell, and so on.
