Arnorin DB9 Null Modem Female to Female Slimline Data Transfer Serial Port Adapter 2 Pack

Worked perfectly, delivered quickly.

These adapters are a must-have for anyone working with serial connections. The slimline design minimizes strain on computer ports, and the gold-plated contacts ensure reliable connections even after repeated use . The removable and reversible screws add flexibility, making them compatible with various setups. Whether you're connecting legacy hardware or setting up a console interface, these adapters perform flawlessly. Highly recommended

These are good and cheap. They've never not worked.

These are awesome. The screws can be removed without them falling apart so I can plug them directly into my cable and into the device I am connecting to. My only complaint is that they came in a 2-pack with the same genders. I don't need 2 of the same thing. 1 of each type would have been more useful to me. Male to male, female to female and male to female in one kit would have been perfect.

Work exactly as described. I needed these to connect a projector to a Raspberry Pi to control the projector.

Well made, work well. Arrived quickly

Works great

Worked as advertised

These adapters (as sold by dgjiachen) conform to the "Full Handshaking" pinout described on Wikipedia (search for "Null modem"), so by-and-large will work with normal serial ports without any special settings. I have used one to connect a PL2303-based USB serial adapter to the serial port of a server so that I can do some startup troubleshooting via the console. Took advantage of the twin pack, as one shall inevitably go walkies when surrounded by envious techies curious about how I make fixes as close to the metal as possible...

Bonjour, conforme au descriptif, très bien.

Produkt wie beschrieben

Good quality, but pricy.

There are lots of serial devices wired to expect a modem connection, including most usb-db9 adapters. This is just what was needed for programming up my firewalls
