The Easy DS-101 One-Way is a plug-and-play USB to DS-101 COM port adapter for Windows 10 and 11. No drivers are required — simply connect the device, and it enumerates as a COM port, ready for your own DS-101 applications or one of the pre-built, downloadable applications we provide.
Engineered for high-assurance environments, the Easy DS-101 One-Way provides hardware-enforced one-way data flow from the Fill Port to the USB host, ensuring that no data from the USB side can ever pass back upstream.
In addition to its security benefits, the adapter delivers up to 6× faster transfer speeds compared to legacy 9600 baud RS-232 connections, while eliminating the need for a physical RS-232 9-Pin interface — which is no longer standard on today’s computer hardware. It works seamlessly with ACES, DMD Power-Station, iApp, and Tier 3 devices including SKL, TKL, and RASKL®.
The API is compatible with both the fully featured UPhil product and the Easy DS-101 subset. The adapter actively zeroizes after each transfer to eliminate residual data risk.
Currently supported on Windows 10 and 11. Custom cable options are available. A Certificate of Volatility can be provided upon request to support compliance and accreditation requirements.
