Such behavior is achieved due to the use of virtual serial port technology which emulates standard COM ports. When the attached serial port device sends communication data it will be actually transmitted over TCP/IP network. Thus, any serial port device connected to COM port at local PC could be accessed from anywhere in the world via internet, for example. Another example is the HD15 connector used by monitors-most monitor cables only are loaded with 14 pins, but it is still called an HD15 connector.Serial to Ethernet Connector is an advanced software solution developed to share serial port devices over TCP/IP network. In some cases, a DB25 connector may only have 4 or 5 pins loaded into it however, it is still called a 'DB25' connector and not a 'DB4' or 'DB5'.

MD connectors can use latchclips or thumbscrews as anchoring mechanisms.ĭ-sub connectors are usually described by the total number of pins that they can hold.

These are often used in SCSI applications, and the most popular types are the MD50 and MD68 connections. The MD is also commonly called a 'half-pitch' DB connector. This connector is slimmer than a standard D-sub, with pins even smaller than the ones used on HD connectors. DB and HD connectors use thumbscrews to secure the connector in place.Īnother type of D-sub is the MD, or Micro DB connector. The most common HD connector is the HD15, which is found on PC video cards and monitors. HD connectors often have three rows of pins instead of two. This is typically referred to as an 'HD' connector.

One special type of D-sub connectors is the High-Density DB style, which looks just like a regular DB connector, only with pins that are slightly smaller and placed closer together. Common types of D-sub connectors are DB9 and DB25, used on PCs for serial and parallel ports. Most DB connectors have two rows of pins. The connector gets its name from its trapezoidal shape that resembles the letter 'D'. The official name is D-subminiature, but many people call it 'D-sub' or just 'DB'. The DB style connector is a common connector ufd in many computer, audio/video, and data applications. DB Style Connector Guide & Cables What are DB style connectors?
