Wow, I've not encountered a DB9 connector in like 20 years. Is this relevant for "legacy" equipment? Or are there still DB9 ports on some new equipment?

- uncledave 6y agoYes lots of bits of industrial and electronic equipment still ships with it. For example: https://resources.aimtti.com/datasheets/AIM-1908_multimeter_data_sheet-Iss3.pdf https://resources.aimtti.com/datasheets/AIM-1908_multimeter_... Most of the stuff that runs over USB in that sector is just a serial port as well.
- intrasight 6y agoI get the "serial port" part. Just find it curious that the DB9 port is still used in new equipment.
- uncledave 6y agoIt’s cheap and reliable.
- zwieback 6y agoI do encounter a lot of DB9 serial ports, some requiring real RS232 voltages. For me it's mostly old equipment, since factory automation and monitoring equipment can easily last decades there's still a huge installed base.
- bityard 6y agoNot sure what you mean by relevant for legacy equipment? Yes? Computers for consumers mostly stopped shipping with DB9 ports a decade or more ago (although, fun fact, my 3-year-old Dell Precision has a real RS-232 port via the dock) but RS-232 and its TTL equivalent are still in heavy use in industry, datacenters, and embedded computing.
