What is a D-SUB Connector used for?
D-Sub ports are used for connecting external devices to a computer. They are an older method of connection, but some modern computers still contain them. These ports are gradually being replaced by more efficient connection technology, such as USB and Thunderbolt.


Is DB9 the same as RS232?
RS-232 is a signalling standard, and DB9 is a connector standard. Most cables that are intended to carry RS-232 signals, have DB9 Connectors -- but some RS-232 cables have different connectors, and some cables for other signals have DB9 connectors.


What devices use DB9?
DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity. Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and Others.


What is DB 9 connector used for?
The DB9 connector is mainly used in serial ports, allowing asynchronous data transmission according to the RS-232 standard (RS-232C). Note that there are DB9-DB25 adapters that easily convert a DB9 socket to DB25 and vice versa.

 Can you connect DB9 to VGA?
Quickly and easily connect your hard-wired MultiSync® monitor from the VGA video card to a 9-pin cable input. Make the right connection! This adapter allows the MultiSync® DB9 style video output port on a desktop or laptop computer to connect to a VGA (HD15) style video input port on a monitor.

Which pins on the db9 connector are for communication?
Serial communication devices make use of 9 or 25 pin D-type connectors for their cabled connections. They are commonly designated as DB-9 or DB-25 with the number used to differentiate between the pin counts.

What is the difference between DB25 and db9 serial ports?

DB9 was a 9 pin connector and DB25 was a 25 pin connector. They were used for peripherals such as serial printers, mice, game controllers and modems. We always called them RS-232 ports or a COM port. Serial ports are very slow, I only used mine for my mouse and my very first modem.
