I/O Controller 2 connects a full RS-232/485 serial port and a set of eight digital inputs and eight digital outputs to the Ethernet. It features a truly full RS-232 serial port (9-pin). The serial port of the unit can be connected to a PC over the LAN, with the serial port accessible in Windows as a Virtual Serial Port (VSP). Its digital inputs and outputs can be controlled over the Web or through Modbus/TCP.A built-in web server is used for configuring. Using the free HW VSP3 application, up to 100 remote serial ports can be connected to one PC.Two devices can be connected in Box-2-Box mode. In this mode, the digital I/O as well as the RS232/485 serial line is extended (tunneled) over the LAN.Features:1x full serial port RS-232/485 with 9-bit communication support8x Digital Input (for Dry contacts, switches, or 5–20V DC)8x Digital Output (Open Collector)M2M communication protocols: HTTP, Telnet, TCP Server, TCP Client/ServerConnected via LAN.
