RSLogger – RS232 & RS485 Data Logger and Serial Communication Recorder

RSLogger is the official hardware serial data logger product line developed by Electroware, designed for professional RS232 and RS485 communication recording, data capturing, and long-term archiving. It acts as a reliable hardware “black box” for industrial equipment, laboratory instruments, and embedded systems, allowing engineers and technicians to monitor and analyze serial data streams without interrupting device operation.

Reliable Serial Data Logging

Depending on the model, RSLogger can operate as a serial data logger, RS232 recorder or RS485 recorder. Features include Ethernet connectivity, USB storage, Virtual COM over TCP, industrial-grade internal memory with USB backup and precise timestamps using RTC and NTP synchronization.

Industrial and Technical Applications

RSLogger devices are widely used for monitoring communication with PLC controllers, CNC machines, laboratory instruments, POS systems and serial printers. Engineers and technicians rely on RSLogger to diagnose communication problems, archive device output and analyze serial protocols.

Custom Hardware and Firmware Solutions

The RSLogger platform can be adapted to specific applications. Hardware and firmware customization options allow integration with existing systems and specialized installations, making RSLogger a flexible platform for both standard and OEM projects.

Professional RS232 Data Loggers and Serial Monitoring Devices

RSLogger is a series of professional hardware data loggers designed for recording and monitoring serial communication in real time. Our devices help capture RS232 data streams from industrial equipment, laboratory instruments, printers, POS systems and many other serial devices. Unlike software-based solutions, RSLogger works as a standalone hardware logger and does not interfere with the operation of the monitored equipment.

Depending on the model, recorded data can be stored in internal memory, backed up to USB storage or accessed over the network. This makes RSLogger a practical solution for diagnostics, long-term monitoring, troubleshooting and archiving serial communication logs.

RSLogger Hardware Data Logger Range

The RSLogger family includes several models designed for different applications and environments:

  • RSLogger PRO – advanced RS232 data logger for professional monitoring and flexible configuration
  • RSLogger Basic – simple and reliable serial logger for everyday monitoring tasks
  • RSLogger ECO – compact and cost-effective hardware logger for standard RS232 applications
  • RSLogger Module ECO – compact embedded solution for integration into custom systems
  • RSLogger Basic Industrial – industrial serial logger designed for control cabinets and automation systems
  • RSLogger PRO Industrial PoE – network-ready industrial logger for advanced installations

Typical Applications of RS232 Data Logging

RS232 communication is still widely used in industrial, technical and laboratory environments. RSLogger devices are commonly used wherever stable serial communication monitoring and reliable log archiving are required.

  • Industrial automation – monitoring communication between controllers, machines and industrial devices
  • Laboratory equipment – logging measurements and serial data from analyzers, scales and test instruments
  • Serial printers – capturing printer output, reports and text-based logs
  • POS and payment systems – archiving transaction logs and device communication
  • Diagnostics and troubleshooting – recording serial communication for service, debugging and fault analysis
  • Embedded systems – collecting data from serial devices in custom technical installations

Reliable Hardware Logging Without a PC

One of the key advantages of RSLogger devices is the ability to work independently without a permanently connected computer. This makes them especially useful in industrial environments, technical service applications and installations where long-term logging must be stable, discreet and maintenance-free.

If you are looking for a dependable RS232 logger, serial data recorder or industrial serial monitoring device, the RSLogger range offers practical solutions for both simple and advanced use cases.
