MDV1-9PH019

Introduction

The D-subminiature - also referred to as D-sub - is a large family of electrical connectors. It is most commonly used to connect computers, peripherals, and other devices. The MDV1-9PH019 is a type of D-sub connector, designed for a particular application and has a specific working principle. In this article, we will discuss the application field and working principle of the MDV1-9PH019.

Application Field

The MDV1-9PH019 is a type of D-sub connector, primarily used for data signal transmission. The connector, with its 9-pin design, is used mainly when connecting multiple devices in a serial communication system. For instance, it can be used to connect two computers, two LCD displays, two Ethernet devices, and other digital data processing systems.

Additionally, the MDV1-9PH019 is also suitable for connecting a computer and a printer. It provides data transmission at a rate of 9600 baud, with a maximum baud rate of 115200. The data transmission speed is adjustable according to various application needs.

Working Principle

The MDV1-9PH019 connector consists of 9-pins and can transmit data through two data lines. The first line is designated as “Data In” and the second line is designated as “Data Out”. The “Data In” line transmits data from the computer to the printer, while the “Data Out” line transmits data from the printer back to the computer.

In the “Data In” line, data is transmitted in 8-bit frames, with a start bit, a stop bit and 5 bits of data. The data transmission speed is controlled by the baud rate. The “Data In” line accepts the data at the baud rate and then determines the essential characteristics of the data, such as the data length and format.

The received data is then converted into parallel format and transmitted through the “Data Out” line. The “Data Out” line accepts data at the same baud rate as the “Data In” line, and then transfers it to the destination device. This process is repeated every time data is sent or received.

Conclusion

The MDV1-9PH019 connector is a type of D-sub Connector which is primarily for data signal transmission. The most common applications for the MDV1-9PH019 include connecting two computers, two LCD displays, two Ethernet devices, and other digital data processing systems. Additionally, it can also be used to connect a computer and a printer. The connector transmits data through two data lines, “Data In” and “Data Out”, and the data transmission speed is adjustable according to the baud rate.
