Serial to USB and back.
FTDI chipsets means no driver issues. My PC found the right drivers automatically.. Come in male and female D9 . Make sure you get the right ones or get the "sex change" adaptors.

Not working, support website inoperable
The product support website link does not work so I guess I'm coming here. Here's what AI is helping me figure out. The adapter is physically defective. An RS-232 Transmit (TX) line must idle at a negative voltage (typically -5V to -15V). Because your Pin 3 measures 0V, the internal line driver is dead. This is a hardware failure confirmed across two separate host devices. You cannot fix this with software; request a replacement. Defect: Pin 3 (TX) shows 0V; it must be negative. Verification: Tested on Pi 3 and Pi 5; both show 0V. Action: Initiate a return/replacement.
