Each shell size usually (see below for exceptions) corresponds to a certain number of pins or sockets: A with 15, B with 25, C with 37, D with 50, and E with 9. [6] . For example, DB-25 denotes a D-sub with a 25-position shell size and a 25-position contact configuration.

Wiring, pinout and signals for the full 25-pin RS232 connector.

DB-25P-K87 – 25 Position D-Sub Plug, Male Pins Connector from ITT Cannon, LLC. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

Jul 11, 2008 · The DB-25 connector (named for its "B"-size "D"-shaped shell and 25 pins) is practically ubiquitous in the electronics industry. The DB-25 connector is used for a variety of purposes. Two common applications are RS-232/EIA-232 (serial) connections, and the parallel printer interface on the IBM PC.

Oct 27, 2016 · Most of the pins on DB-25 connectors are not connected since only nine pins are used for RS-232, RS-422, and RS-485 communication. To perform a loopback test with no hardware flow control with a DB-25 connector, connect pins 2 to 3 for RS-232. For RS-422/485 connect pins 5 to 20 and 7 to 22.

The DB25 connector has 25 pins, with each pin having a specific purpose. Understanding the pin diagram of the DB25 connector is essential for correctly wiring and configuring devices that use this connector.

3 days ago · Most new computers have two COM ports with 9 pins each; these are DB-9 male connectors. Older computers would have one DB-9 male connector and one DB-25 male connector. The 25 pin male connector is pretty much the same as the 9 pin, it's just bigger. Let's have a look at a serial port to see what we are talking about: Figure 2.

These pins provide a safe path for the dissipation of electrical charges and help prevent signal interference or damage to connected devices. By ensuring a solid ground connection, the Db25 connector pins contribute to maintaining signal integrity and overall system performance.
