  Serial ports are an important part of many embedded systems. However, it is hard to find them on desktop PCs and laptops because of replacements. The most common type of serial cable, straight-through serial cable, is useful to connect a Data Terminal Equipment (DTE) device to a Data Communications Equipment (DCE) device (for example, a modem). Let us know more of its type: Types of Serial Cables Data communication among digital devices is performed by serial cables, which are useful to transfer data between devices that use serial port communication techniques. Most of its types use RS-232 (Recommended Standard-232) standard interface to communicate that mainly specifies that data should be sent in a predefined sequence of bits. Also, there are some special modifications in serial cables like male and female combinations, for example, DB9 serial cables can come in DB9 F/F and DB9 M/M, DB9 M/F, or DB9 F/M. Here DB9 serial cables categorization is shown where F means female and M...

Originally known as ‘ D-subminiature ’ DB style connectors are common UFD connectors or say monitor cables which operate in computing devices, audio/video, and data applications. DB25 and DB9 serial cables are the renowned types of D-sub connectors, used in PCs for serial and parallel ports. The High-Density DB style is another type of D-sub connector which looks like a regular DB connector. Often called ‘HD’ connectors they have three rows of pins instead of two. HD15 is the most common type of connector used for video cards and monitors. Micro DB connector comes with smaller pins than the HD connector pins. It is commonly known as a ‘half-pitch’ DB connector. Majorly, SCSI applications use them. MD50 and MD68 are the most popular connections types. The D-sub connectors’ names are equivalent with the total number of pins that they can hold. For example, DB9 Series Cables contain 9 pins. However, in some cases, a DB25 connector has 4 to 5 loaded pins. Another product is the HD1...

Serial communication used to be one of the major ways to connect peripherals like scanners, joysticks and printers to PCs for several years. One of the most commonly used cable connector for this type of communication was 9-pin D-Subminiature connector which is also known as DB9 cable or a DE-9 cable. DB9 serial cables  has nine pins which were enough to carry data in the series. But it has certain drawbacks which made their usage less frequent. People started to prefer  USB cables  over DB9 cables. However, if you shop for electronics, you will still find several devices having DB9 cables or ports on them. Let us check out some of the advantages and disadvantages of DB9 D Subminiature Connectors. Advantages of DB9 Subminiature Connectors DB9 connectors have several advantages. You can easily customize them with 9 individual pins to carry serial data. Although the speed of these connectors is low as compared to other standards like USB, the length of these cables ...

If you deal in cable and connectors, you must have come across the term DB9 Connector. This connector is named like that because of its trapezoidal shape that looks like letter "D". It has been designed in such a way that it can work with EIA/TIA 232 serial interface standard and used for Serial Asynchronous Data Transmission. You will find DB9 Connectors used with computer, audio/video, and data applications. DB9 ports were quite popular during the initial years; but with the introduction of usb, firewire etc its popularity declined. The RS 232 is the recommended standard for enabling serial data transfer between DCE (Data Circuit-terminating Equipment) and DTE (Data Terminal Equipment). When you buy these connectors, you can recognize them by the letters A to E that denote the shell size and also by the number of pins. M or F indicates whether it is a male or a female connector. Let us know more about these connectors, their types, electrical specifications and ...
