There are numerous, many totally different serial communication architectures and requirements. However in case you’re working with an outdated laptop or CNC machine, you’re in all probability taking a look at RS-232. That DE-9 serial port on the again of the pc, which was ubiquitous for a time, is for RS-232. The issue is that trendy computer systems don’t have them, which is a matter if you wish to talk one thing that requires RS-232. To resolve that downside, Anders Nielsen designed the final word USB-C-to-RS-232 adapter.
This can be a new, upgraded model of the design, which Nielsen up to date as a result of he obtained such a optimistic response after releasing the unique. Why are individuals so smitten by it? As a result of it solves a really actual downside.
To clarify how, I’ll inform you a fast story. Again in 2016, I purchased an outdated Hurco VMC (vertical machining heart) made in 1982. It may learn g-code from floppy disks, however that restricted the dimensions of the information and due to this fact the complexity of the elements. The choice was “drip-feeding” g-code, which required RS-232 communication. As a result of new computer systems don’t have RS-232 serial ports, I purchased an outdated laptop only for that job. The state of affairs has solely turn out to be worse within the decade since then, as these outdated computer systems turn out to be rarer.
That and related conditions are frequent. Typical adapters available on the market are infamous for being unreliable, as exact timing is vital.
Nielsen’s adapter is open-source, modular, and very versatile. It’s modular within the sense that the PCB is in three sections that you may break aside, in case you don’t want all the capabilities which are out there.
And that could be the case, as Nielsen has seemingly included the whole lot anybody may ever want. Your gadget is 3.3V? Swap a jumper. Your gadget has inside RX and TX crossover? Swap a jumper. Your gadget has some unconventional port? Simply solder a header within the offered location and join jumper wires.
I’m genuinely struggling to consider any situation that you simply couldn’t accommodate with this adapter.
And it’s reasonably priced, too. The worth is simply 28,52€ (about $33.00 USD), which isn’t rather more than the everyday problematic adapters out there on Amazon. And since it’s open-source, you may merely make your personal in case you want.
