What is a serial DB9 connector used for?

 USB to RS-485 Adapter Cable



DB9 connectors used to be very common on PCs and servers. The DB9 connector is designed to work with the EIA/TIA 232 serial interface standard, which identified the functions of all nine pins as a standard so that multiple companies could design them into their products. DB9 connectors are commonly used for serial peripherals such as keyboards, mice, joysticks, etc. They are also used in DB9 cable assemblies for data connections.




How do I connect DB9 to my laptop?



DB9 Serial FTDI Cable



Plug the serial DB-9 end of the console cable into the serial DB-9 port on the laptop. If your laptop does not have a serial DB-9 port, plug the serial DB-9 end of the console cable into the serial DB-9 end of the USB to Serial DB-9 Adapter, then into the USB port on the laptop.



What is meant by RS232 DB9 pin connector?



RS232 monitoring hardware establishes the connection between data terminal equipment (DTE) and data communication equipment (DCE). In order to link these devices, the RS232 D9 pinout is essential as this pinout will allow you to successfully connect the two devices



USB-to-Serial cable produced by Premier cable will connect a device with a serial connector to your USB port on your computer.
