Available for order.

The BPI‑55 interface converter is designed for:

  • 🔄 Bidirectional electrical signal conversion between RS‑232C and USB interfaces;
  • Operation in asynchronous data transfer mode, compatible with most industrial controllers, recorders, and sensors;
  • 🛡 Galvanic isolation between the industrial communication line and the PC, protecting equipment from potential differences and transient processes;
  • Reliable data exchange between the PC and industrial devices without the need for a hardware COM port.

When connected to a computer, the device creates a virtual COM port, allowing the use of existing software (SCADA systems, configurators, monitoring systems) without modifications or additional adaptation.

Main Functions:

  • 🔄 Mutual signal conversion RS‑232C ↔ USB;
  • Automatic data direction detection;
  • 🛡 Galvanic isolation of interfaces, protecting the PC and equipment from surge voltages and leakage currents;
  • 💻 Virtual COM port support, compatible with all standard serial communication software;
  • 🔋 Powered via USB, no external power supply required.

Electrical and Functional Specifications:

  • Interfaces:
    • USB 2.0 (compatible with USB 1.1/3.0)
    • RS‑232C (asynchronous mode, standard ±12 V signal levels)
  • Communication mode: asynchronous
  • Galvanic isolation: between USB and RS‑232C
  • Supply voltage: 5 V DC (from USB)
  • Data rate: up to 1 Mbit/s
  • Virtual COM port: automatic driver installation (Windows 10/11)

Supported Operating Systems:

  • Windows: XP / Server 2003 / Vista / 7 / 8 / 8.1 / 10 / 11
  • Linux: kernel versions 2.6.x / 3.x.x
