The HW group I/O Controller 2 is a versatile solution for integrating RS‑232/485 interfaces and digital I/O into Ethernet networks. Featuring a full‑featured 9‑pin RS‑232/485 port, eight digital inputs, and eight digital outputs, it seamlessly combines serial communication with modern networking technology — ideal for industrial, commercial, and security applications.

From barcode scanners and access systems to vending machines, the I/O Controller 2 offers maximum flexibility, durable hardware, and easy configuration to enhance connectivity across your automation and monitoring infrastructure.

Functionality and Applications

The I/O Controller 2 connects one RS‑232/485 port and eight digital I/Os to a LAN network. Using the free HW VSP3 software, the serial port can be accessed as a virtual COM port in Windows, supporting up to 100 remote serial ports on a single PC.

The digital inputs and outputs can be controlled through the web interface or via Modbus/TCP protocol, allowing easy integration into SCADA systems or industrial control software.

Box‑to‑Box Mode:

Two I/O Controller 2 units can be connected via LAN in Box‑to‑Box mode, tunneling serial and digital I/O signals bidirectionally. This extends the range of RS‑232/485 connections and digital signals without additional physical wiring.

Typical Applications:

• Connecting RS‑232 devices such as barcode scanners, RFID readers, printers, or displays
• Controlling actuators such as locks, signal horns, or power switches
• Monitoring sensors (e.g., PIR motion detectors, door contacts, or security systems)
• Automating vending machines, access control systems, or UPS management

Technical Specifications

• 1× RS‑232/485 port (RxD, TxD, GND, CTS, RTS, DSR, DTR, RI, CD), up to 115,200 Bd
• 8× digital inputs (potential‑free, 5–20 V DC)
• 8× digital outputs (open collector, max. 50 V / 0.5 A)
• M2M protocols: HTTP, Telnet, TCP Server, TCP Client/Server
• Configuration via integrated webserver or Telnet
• Supports Modbus/TCP and RFC2217
• Free HW VSP3 software: NT service, x64 support, up to 100 virtual COM ports

Developers can use the HWg SDK with examples in C++, C#, PHP, Java, and other programming languages, making integration into custom applications and SCADA systems fast and straightforward.

Digital Signal Control

The eight digital inputs of the I/O Controller 2 capture switch signals or status feedback, while the eight outputs directly control external devices or relays to trigger actions — for example, opening a gate or activating an alarm.
