These nine-pin connectors are available in vertical or right-angle orientations for top or side cable entry.ĭ-subs are available in a wide range of plating options to meet application cycles plus a wide range of mounting options for very secure connections. These signals should be connected using twisted-pair cable. CANH and CANL are signals lines that carry the data on the CAN network. The 9-pin D-SUB connector follows the pinout recommended by CiA DS 102. There are numerous uses for this connector, whatever name you give it. Solution High-Speed-CAN hardware have a 9-pin male D-SUB (DB9) connector for each port. A “DB-25” connector has a “B” size shell, but the common nine-pin connector is smaller and has an “E” size shell. The DE-9 D-sub 9-pin connector is often mistakenly referred to as the “DB-9” connector. What is the Difference Between DE-9 and DB9? Most contemporary interfaces, including USB, PS/2, Firewire, and others, have largely supplanted the DB9 in use today. Also they are used on DB9 cable assemblies for data connectivity.
DB9 CONNECTOR PINOUT SERIAL
DE-9 connectors are frequently used in CAN female connectors are on the bus and male connectors are on the devices.ĭB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Manufacturers don’t always use the same methods, so you might need specialized cables.įor some computer networks, including token ring networks, DE9 connectors were employed. These frequently use the handshaking control lines rather than sending data serially to the computer to signal low battery, power failure, or other conditions. In order to communicate with the connected computer via an RS-232 interface, many uninterruptible power supply units have a DE-9F connector on them. Initially, RS-232 devices used the DB25, but for a number of applications, the less common signals were skipped, allowing a DE-9 to be used. Read More: What’s A Smart Connector? Where Are DB9 Connectors Used?ĭespite the fact that the standard did not make this connector mandatory, RS-232 serial communications is the most common use for D-subs. A “DB-25” connector has a “B” size shell, but the common nine-pin connector is smaller and has an “E” size shell. By itself, the connector pin spacing does not lend itself to breadboard or perfboard use, but this adapter makes it very easy.
