Serial (DB9) to USB-C Connector
Have you ever tried plugging something old into something new, and it just didn’t fit? Like trying to charge an old toy with a new charger? That’s the kind of problem some people have when working with really old computers and machines. One of the most common connector types starting in the early 1960s was the “serial” connection or “DB” connector.
A serial connector is a type of plug used to connect devices like computers, printers, and modems. It sends data one bit at a time, in a single line – like sending letters one by one through a pipe. This was the main way for computers to talk to other devices before USBs (Universal Serial Bus) became popular.
The first serial port (specifically the RS-232 standard) was invented in 1960 by a group called the Electronic Industries Association (EIA). It was made to help different kinds of machines communicate easily.
It became widely available to the public in the early 1960s, especially when computers and terminals started using it more often in offices and labs. By the 1980s the DB9 was the most common serial connector and was a common feature on most computers.
Sabrent has created a special cable that lets old machines talk to new computers. It’s called a DB9 Serial to USB-C cable.
DB9 Serial is an old way that machines used to send information to each other. It’s a type of plug that has 9 little pins. USB-C is the newer, smaller plug that you see on most new computers, tablets, and phones today. It’s the oval-shaped one you can plug in either way!
Why is the serial connector to USB-C important?
A lot of businesses and even schools still use really old equipment like:
- Old computer screens (called terminals)
- Printers
- Modems (a device that helps computers talk over the phone line)
- GPS systems (machines that tell you where you are)
But new computers don’t have the old DB9 Serial plug anymore. That’s why this new Sabrent cable is so helpful It acts like a translator so old machines and new computers can understand each other.
