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 support
• 8x Digital Input (for Dry contacts, switches, or 5–20V DC)
• 8x Digital Output (Open Collector)
• M2M communication protocols: HTTP, Telnet, TCP Server, TCP Client/Server
• Connected via LAN. Configuration via built-in web server or Telnet
• Full RS-232 serial port (9 pins: RxD, TxD, GND, CTS, RTS, DSR, DTR, RI, CD)
• RS-485 serial interface: up to 115,200 Bd
• Free software HW VSP3: Virtual Serial Port for Windows (NT service, x64 systems), supports up to 100 remote serial ports
• Compatible with third-party SW; programming examples available in the HWg-SDK (Borland C++, MS Visual, VB, C#, PHP, JAVA, and more)

Applications and usage:

• Link up to eight buttons / switches with a software application
• Connect RS-232 devices to your LAN (barcode / RFID scanners, serial printers, displays)
• Control outputs remotely to open doors, trigger alarms, or disconnect power
• I/O can be controlled over Modbus/TCP from any SCADA system, independently of the serial line
• Remote control of power and other technology over RS-232 and RS-485
• Remote control of displays and signal lights
• Remote status checks of PIR sensors, door contacts, and security systems
• Integration with card readers, RFID, vending machines, security alarms, access control systems
• UPS control and logging devices
• Barcode scanners
