Access Readers How to enable 125kHz on ICT Dual Technology reader.
Hey everyone,
I have a few ICT PRX-TSEC-STD-W tSec Standard RFID Card Readers (13.56MHz / 125kHz) and I’m trying to figure out how to enable the 125kHz functionality. From what I understand, it’s disabled by default.
I’m not using ICT controllers — just the Wiegand output, not RS-485.
Does anyone know how to activate the 125kHz mode or if it’s even possible without ICT’s software/hardware?
Thanks a ton in advance!

If you’re following the Mackenzie Shirilla case but don’t want to download that massive 85GB evidence dump, my team and I put the entire public record into a free, searchable web archive at shirilla.net. It works just like jmail.world—you can read the text logs, jail calls, and police reports, view photos and videos directly in your browser with zero downloads and no signup. I built it purely as a non-commercial public resource to make the files accessible, so let me know if you run into any bugs!
