DSD TECH diDatatracker Isolated Protocol Analyzer, Support RS232 RS485 TTL, Windows Mac Linux

SEE BOTH SIDES AT ONCE - THIS IS A SNIFFER, NOT A USB ADAPTER: A USB-to-serial converter lets you talk to one device. diDatatracker sits passively on the line and captures BOTH directions simultaneously, merged onto one timestamped timeline. Plug in USB-C and two virtual COM ports appear, ready to capture - nothing to configure. Works with RS232, RS485 and TTL (3.3V/5V). 3000Vrms SIGNAL + 1500V POWER ISOLATION: A complete electrical barrier between your laptop and the bus. Blocks high-voltage spikes, ground loops and EMI on factory floors where the ground reference cannot be trusted. Competing taps at 6-11x the price do not publish an isolation rating at all. ALL THREE BUSES IN ONE BOX: RS232 (dual DB9 female), RS485 (dual channel terminals) and TTL at both 3.3V and 5V logic - switch between MCU bring-up and industrial PLC monitoring without level shifters or a second adapter. USB-C host connection. Windows, macOS and Linux - most systems already carry the USB serial driver it needs, and the manual shows you where to download it if yours does not. FREE OPEN-SOURCE SOFTWARE INCLUDED, ON GITHUB (WINDOWS): diSerial, our companion application - no licence, no subscription, no account. Both channels on one merged timeline, with recording and export. Nine interface languages. Source and download are both public under Apache-2.0, so your IT department can read every line before approving it - and it contains no network code at all. Windows 10 and 11 (x86 and ARM64); macOS in development - the hardware itself works on all three.
