I/O Controller is a unit containing 8x digital input over ethernet, 8x digital output over ethernet and RS-232/485 serial (Terminal server) interface. All the interfaces are accessible over a network using the M2M (Machine to Machine) protocol on TCP/IP.


Two devices can be connected to each other (the Box-2-Box mode), digital signals and RS232 can then go back and forth across the network.

The I/O Controller contains:

* 1x RS-232/485 (Terminal server, virtual serial port)
* 8x digital input
* 8x digital output

The product can not only be a "TCP Server", but also can act like a "TCP Client/Server". This means, when your digital input value changes, IO Controller connects to the server via TCP/IP and sends a 7-byte information packet about the input change over the M2M (Machine to Machine) protocol.
