- SCADA engineers testing substations and RTUs
- Worth noticing
- The adapter is described as hardware-timestamping bytes and exposing RXD, TXD, RTS, CTS, and DCD edges.
Field notes
The proposed adapter handles timing-critical work in its own microcontroller rather than relying on a USB-to-serial cable, according to the page. Its software is described as decoding protocol messages beside raw bytes and supporting scripted pass/fail runs, with command-line execution and HTML reports. The site also names older formats such as Conitel 2020 and CDC Type I/II.
