DB9 connector advantages and disadvantages and application areas
DB9 connectors are used in many places and have a large demand in the market. For such a product, do you know its advantages and disadvantages? Konnra connector engineers will introduce you in detail below DB9 connector advantages and disadvantages and application areas.
1. Advantages of DB9
What do you know about the advantages of the DB9 connector? You can easily customize them to transfer serial data using 9 independent pin DB9 connectors. Compared with other product standards, DB9 has a lower speed, but the length of the cable is quite long. If there is a DB9 connector on the old device and there are several conversion options, other standard converters such as USB and Ethernet also allow you to use the device on any computer.
2. Disadvantages of DB9
It is very difficult to connect and disconnect the DB9 connector in a small space. The pins of the DB9 connector are usually exposed, with a high probability of damage. Although it can be connected to the device without any thumb screw hardware, the time left on the device is less likely. On the other hand, if a thumb screw is used, the connector will take a long time to insert and pull out.
The application field of DB9 connector mainly involves three aspects of communication, network and video. The specific contents are as follows:
1. Communication port
One of the most widely used D-sub is for RS-232 serial communication. Although this standard has not yet been mandated, it has been accepted by the industry. RS-232 equipment is initially used
DB25, but for many applications, the less common signals are omitted, and DB9 and male connectors are allowed. Many uninterruptible power supply units are equipped with DB9 connectors for
The RS-232 interface sends a signal to the connected computer. These usually do not send data serially to the computer, but use a handshake control line to indicate low battery, power failure or other conditions. However, this use among DB connector manufacturers is not standardized and may require special cables.
2. Network port
DE9 connectors are used in some token ring networks and other computer networks. The DB9 connector is usually used for CAN: the DB9 connector is located on the bus, and the DB9 male connector is located on the device.
3. Computer video output, game controller port
After reading the above, you should already know the application field of the DB9 connector. More technical documents on the DB9 connector, the Dessault operation team will continue to organize and publish it on the d-sub technical topic page to share with you.
