RSLogger ECO

RSLogger ECO – Compact RS232 Data Logger with USB-A Mass Storage

RSLogger ECO is the smallest and most affordable RS232 hardware data logger in the RSLogger family. Designed for service, education, and automation tasks, it provides fully stand-alone RS232 data recording with 1 ms timestamp precision. Communication is stored in 512 MB ECC Flash memory and can be accessed instantly via the USB-A Mass Storage port – just like a flash drive, without any drivers or software. Power is supplied through the Micro USB port (5 VDC), used only for power input, while a rechargeable RTC battery maintains accurate time even when the device is disconnected.

Main Features

• 512 MB ECC Flash – circular buffer with error correction for months of RS232 logging.
• USB-A Mass Storage (FAT32, 1–32 GB) – automatic log saving in TXT/HEX format, no software required.
• 1 ms timestamps – precise time-stamping for every data frame.
• RTC with rechargeable battery – keeps real-time clock after power loss.
• Low power consumption – around 15 mA @ 5 VDC.
• Compact plastic enclosure – lightweight, ESD-safe housing with 2× RS232 DB9 connectors (male & female) for inline 1:1 installation.
• No Virtual COM, text menu, or data forwarding – a simple and reliable plug-and-log design.
• Optional Mounting Kit – enables secure wall or panel installation.
