DB9 Null Modem Adapter Male to Male 5 Pack

Perfect connector and convertor from straight to cross null modem.

These null modem adapters worked perfectly for me. I used them to put two USB RS232 adapters together back-to-back for testing purposes. My only wish was that both sides of these adapters had female screw posts to allow my RS232 adapters to both screw into these null modem adapters. They are perfect for me otherwise.

Have used dozens of these on marine vessels in moist and corrosive environments with a lot of vibration. They hold up well. The narrow design is great. Other null modems are an inch long and take up more space.

As described

not as good as USA product but does work.

RS232 is still around but it is difficult to find support cable products. These adapters fill the bill and work great at a reasonable price.

...to an irritating problem: having to carry two cables, one straight-thru and one null modem. This simple plug on the end of a straight-through cable turns it into a null modem, fast & easy.

Tested all they all were OK. Been using this component for 25 years, not as easy to find anymore.

Very compact null modem/gender changer. Excellent product.
