What port has 5 pins on the top and 4 on the bottom?
The port you're describing with **5 pins on the top row and 4 pins on the bottom row** is the **DE-9 (also known as DB-9) serial port**. ### **DE-9 (DB-9) Serial Port Details:** - **Configuration:** The DE-9 connector typically has two rows of pins—5 on the top and 4 on the bottom—totaling 9 pins. - **Common Uses:** - **RS-232 Serial Communication:** Widely used for serial communication in computers and networking equipment. - **Peripheral Connections:** Historically used to connect devices like mice, modems, and some older printers. - **Physical Appearance:** The DE-9 connector is D-shaped, which helps prevent incorrect insertion. ### **Pin Layout Overview:** Here's a general breakdown of the pin assignments for a typical DE-9 connector used in RS-232 serial communication: **Top Row (Pins 1 to 5):** 1. **Pin 1:** Data Carrier Detect (DCD) 2. **Pin 2:** Receive Data (RXD) 3. **Pin 3:** Transmit Data (TXD) 4. **Pin 4:** Data Terminal Ready (DTR) 5. **Pin 5:** Signal Ground (GND) **Bottom Row (Pins 6 to 9):** 6. **Pin 6:** Data Set Ready (DSR) 7. **Pin 7:** Request to Send (RTS) 8. **Pin 8:** Clear to Send (CTS) 9. **Pin 9:** Ring Indicator (RI) ### **Modern Context:** While DE-9 serial ports were once common on computers and peripherals, many modern devices have shifted to USB and other connection types. However, DE-9 ports are still used in certain industrial, networking, and legacy applications where serial communication is required. If you're working with older hardware or specific industrial equipment, you might encounter this type of port. Always ensure you have the correct cables and possibly adapters if you're connecting to newer systems. --- **Summary:** The DE-9 (DB-9) serial port is the connector with 5 pins on the top row and 4 pins on the bottom row, commonly used for RS-232 serial communication.
