Available in a wide array of stock lengths and gender combinations
Offering also allows connections to DB9 (AT) or DB25 (PC) serial ports

A DB9 connector has 9 pins arranged in two rows, with one row on top of the other. The top row has 5 pins and the lower row has 4 pins. This interface is commonly used for RS-232 serial applications. For several years, DB9 ports were standard equipment on PCs; nowadays, many newer computers are being built without them. On a PC, the serial port is commonly a DB9 male.

The DB style connector is a common connector ufd in many computer, audio/video, and data applications. The official name is D-subminiature, but many people call it "D-sub" or just "DB". The connector gets its name from its trapezoidal shape that resembles the letter "D". Most DB connectors have two rows of pins. Common types of D-sub connectors are DB9 and DB25, used on PCs for serial and parallel ports.

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. This is typically referred to as an "HD" connector. HD connectors often have three rows of pins instead of two. The most common HD connector is the HD15, which is found on PC video cards and monitors. DB and HD connectors use thumbscrews to secure the connector in place.

Another type of D-sub is the MD, or Micro DB connector. This connector is slimmer than a standard D-sub, with pins even smaller than the ones used on HD connectors. The MD is also commonly called a "half-pitch" DB connector. These are often used in SCSI applications, and the most popular types are the MD50 and MD68 connections. MD connectors can use latchclips or thumbscrews as anchoring mechanisms.

D-sub connectors are usually described by the total number of pins that they can hold. 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". 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.

It didn't work - turned out to be my kit, not the lead.

Reviewed in the United Kingdom on 30 October 2018

Size Name: 0.5MStyle Name: SingleVerified Purchase

Tried this lead but I couldn't get the devices at each end to communicate. I'll have to check the pin connx to make sure it actually is a null modem & that I've not been sent an ordinary 'straight through' serial lead by mistake.

EDIT: Checked lead and it is a 'proper' null modem. There are verious types but the pin connx indicate this to be a full connx one. so it looks like there's something screwy about the two bits of kit I'm trying to connect together :-(
