That’s it!
Null modem cable
Just the other day I brought this old RS232 null modem cable from home, as I needed to hook up the oscilloscope to the PC for some waveform capture. I plugged it in and it wasn’t working, so I spent some time troubleshooting. I used a multimeter to check the continuity on the RX and TX pins, and when that failed I assumed the wire must be broken inside. Somehow I already went ahead to cut a ring around the gray wire sheath when I opened up the connector shell.
About
I’m Darell Tan, and this blog chronicles my adventures into electronics projects, security and software development. As a kid, I used to take apart all kinds of stuff (mostly toys); I like to figure out how things work and what makes them tick. But I guess it was easier to get started with software since computers were more accessible, so I spent a large part of my youth working with computers – reading and writing code, and trying out all kinds of software and operating systems.
