🔌 TENMA 72-9265 - Signal Cable Tester for Enhanced SEO Review

Extremely valuable for installing and troubleshooting serial connections. At present, it is mainly used to control professional electronic equipment or to communicate with high-performance equipment for adjustment.

I like it a lot. This is a replacement for what I lost. My complaint then and now. Ditch the threaded bolt and just make it a simple plug. I usually have to remove the grub screw or use a short DB-9 straight cable to adjust.

I used it for debugging bus destination sign RS 232 interface. It does not overload signal lines and immediately informs you about faulty cable connections. In the latter case, I found that the TXD and RXD signals are on opposite pins, resulting in a red light that indicates both a problem and a solution at the same time. A good thing !
