Review on ✨ StarTech Com Black RS232 Serial Modem: High-Performance Industrial Electrical Solution by Matthew Fadoul

What I liked about it is that it worked. got worse. RS232 went the way of the DoDo bird. Unless you're working with archaic electronic devices owned by the museum. So I need a Null RS232 cable. Laptops and/or tablets and/or smartphones no longer support RS232 (aka serial port). First you need a USB to RS232 adapter + driver + a way to check if the simulated port is working. and make sure the adapter is working. This particular cable (female-female) was exactly what I was looking for. The oscilloscope (older than dirt) I wanted to talk to only had an RS232 communications port with a 9-pin gun. Interconnects. The USB-RS232 adapter had a 9-pin connector. Able is configured to expect screwing into threaded sockets. They were on the oscilloscope but not on the adapter. It still works - you just can't move the connections around much. With NI-Max I was able to send a request to a scope that identified itself. The automated testing software performed its tests without any problems. Caveats: Not all null cables are created equal. All that was required in my application required pins 2 and 3 to be folded together. More complex null cables may have jumpers in the rear housings of the 9 pin guns which I believe this cable does not have. This cable twists pins 2 and 3 - pins 1, 5 and 9 go straight through. I couldn't find any jumpers. It seems well done. It works out. What more do you want?
