Serial port data logging

  • PortStore5 can be used as a serial port loggerthat works even during LAN communication outages.
  • Data received from the serial port are safely stored in the internal Flash memory and protected against power failure.
  • RS-232 port of PortStore5 can be simultaneously used for data capture (CDR/SMDR, PBX call accounting) and for remote access (HW VSP – virtual serial port).

PortStore5: Full RS-232 serial port to Ethernet with logging

PortStore5 connects a full RS-232 or RS-485 serial port to a LAN. Features a 4 MB internal flash memory for RS-232 data capture. 
Stored data can be retrieved when the LAN connection is re-established. Remote serial port can be accessed in Windows as a Virtual Serial Port. 
WEB-based configuration and full RS-232 serial port (9 pins).


PortStore5 is a RS-232 and RS-485 serial port to Ethernet converter with an internal memory. PortStore5 features a truly full 9-pin serial port. The serial port converter can be connected to a PC over the LAN, with the serial port accessible in Windows as a Virtual Serial Port (VSP) – e.g. COM17. HW group offers a free HW VSP Multiport application that supports up to 100 remote serial ports on a single PC.


  • 4MB internal memory, protected against power failure
  • Full RS-232 serial port (9 wires)
  • Web-based configuration, free Virtual Serial Port for Windows supports up to 100 ports

For programmers: Control the product from your own application in minutes. Make your work easier with many examples for various programming languages in the HWg-SDK (Borland C++ Builder, MS Visual C, VB, Delphi, C#, PHP, JAVA).




Remote (virtual) COM port over Ethernet (LAN)


    • Remote serial port for connecting any RS-232 device (full serial port = 9 pins).
    • The HW VSP application creates virtual serial ports in Windows (e.g. COM17 and COM18)
    • Connect RS-232/RS485 devices over LAN – barcode / RFID scanners, serial printers, displays, PLC, CNS, various machinery, ...



  • PortBox2 works in the same way but does not have an internal data memory (buffer).
  • PortStore5 stores the serial port data into its internal memory (buffer). If the LAN communication fails, data will be sent to the virtual serial port later.
  • A variety of RS-232/RS485 devices can be connected – barcode / RFID scanners, serial printers, scales, POS cash registers, PLC, CNS, various machinery, ...

Backing up data from remote RS-232 / RS-485 devices


    • Several devices with RS-232 data output are connected to PortStore5 or PortBox2 units.
    • The PS Eye application collects data from all remote serial ports.



  • Data from each device is stored to a separate text (TXT) file for further processing.
  • PortBox2 can be also used to connect RS-232; however, it does not guarantee data storage in case of LAN or power failure (does not have a buffer).




PortStore5 usage examples

  • Backing up data sent to a RS-232 printer
    • Security system status
    • Barcode scanners
    • Scales (weighing systems)
    • Weather stations
  • Connecting RS-232 / RS-485 systems to the Ethernet
  • Logging and analysis of a full RS-232 / RS-485 communication
  • Capturing data from a presence registration system






User software

    • UDP Config – Configuring the product IP address, further configuration over the WEB 
    • Hercules – Configuration (IP address, Telnet configuration) + testing utility for Windows (Serial, UDP and TCP terminal)
    • HW VSP – Free HW Virtual Serial Port for Windows. 
      PortStore5 is also supported by the HW-VSP Multi version that supports up to 100 virtual serial ports on a single PC. 

Data retrieval applications for end users


  • PS Eye 
    Windows application that periodically downloads data and stores it on the PC. Can also work under Win NT/2000/XP in the “NT service” mode. Available as an executable file and source code (Borland C++). 


  • PS2 Config 
    Utility to simplify PortStore2 PL configuration. Includes a PBX emulator for a local serial port to test the system.
