DB9-USB-M

USB, DVI, and HDMI are three types of connectors primarily used for computer, audio-visual, and video applications. The DB9-USB-M connector is an example of this type of connection. This connector is designed to convert a serial data connection from the DB9 male connector to a USB female connector.

The cable used for this type of connector is made up of three copper wires, one for the +5V power supply, one for the Data- and one for the Data+. The length of the cable can be adjusted to fit the connection needs of the application.

Application filed

The DB9-USB-M connector is mainly used in the industrial field, mainly as a serial interfacing device for industrial automation systems. It can be used to connect products like PLCs, barcode readers, LED displays, servos, etc. to computers for data exchange. It is also suitable for medical instruments and data collection or control purposes.

Working Principle

The DB9-USB-M connector works by transferring the serial data from the male DB9 connector of the product to the female USB connector of the computer. The transfer occurs in two steps, which are serial communication port register and data transfer from one port to another. The USB standard is in charge of the communication between the two endpoints.

The adapter comes with a data flow control unit, which is responsible for controlling the flow of data between the two ends. The unit also handles error checking and correcting, packet buffering, and other data protocols. It is also responsible for providing power to the adapter by providing +5V power.

The DB9-USB-M connector has a simple installation process. It fits perfectly into the female DB9 connector and the male USB connector. Then, the adapter is plugged into the computer and it is automatically recognized and the port drivers are installed. Then, the data exchange can begin.

The DB9-USB-M connector is an ideal solution for industrial applications that require serial communication and data transfer between different devices. This connector is easy to use and is reliable and secure. It is also a cost-effective solution when compared to other connections.
