PASSIVE SNIFFER, NOT USB ADAPTER – Captures both directions merged onto one timeline. Plug USB-C, two COM ports appear – zero config. Supports RS232, RS485, TTL (3.3V/5V). 3000Vrms SIGNAL + 1500V POWER ISOLATION – Full barrier between laptop and bus. Blocks spikes, ground loops, EMI on factory floors. Competitors at 6–11x price publish no isolation rating. 3 BUSES IN 1 BOX – RS232 (dual DB9), RS485 (dual terminal), TTL at 3.3V & 5V. Switch between MCU bring-up and industrial PLC – no level shifters, no second adapter. USB-C host. Windows, macOS, Linux – driver built-in; manual shows download if missing. FREE OPEN-SOURCE SOFTWARE (GitHub, Windows) – diSerial: no license, no subscription, no account. Merged timeline, recording, export. 9 languages. Apache-2.0 source – IT can audit; zero network code. Windows 10/11 (x86/ARM64); macOS in dev. Hardware works on all three.
diSerial, the software companion to DSD TECH products, is now officially open-sourced on GitHub (Apache-2.0). It can function as a serial terminal to communicate with a single device and also supports dual-port passive monitoring, merging bidirectional communication between two devices onto a single timeline. It offers cross-platform support for Windows (x86/x64/ARM64) and macOS (Apple Silicon), as well as nine interface languages (including Simplified Chinese), and contains no network code whatsoever, ensuring data security.
