DB9-USB modules can be used to upgrade a UART port of a device to an active USB port. These active connectors contain all the USB to UART (and vice-versa) conversion electronics and are designed to fit directly into the same PCB footprint as a PC compatible UART DB9 connector.

Below is the pinout of a typical standard male and female 9-pin RS232 connector, this connector type is also referred to as a DB9 connector. A computer's serial COM port (DTE) is usually a male port as shown below, and any peripheral devices you connect to this port usually has a female connector (DCE).

compatible UART DB9 connector. The FTDI DB9-USB-RS232 modules are available in two types DB9-USB-RS232-M and DB9-USB-RS232-F. A DB9-USB-RS232-M can be used to replace a male DB9 connector that is wired in a PC compatible RS232 manner. This module operates at RS232 signal levels. A DB9-USB-RS232-F can be used to replace a female DB9 connector ...

This article explores the pinout of the DB9 connector and its application in UART. The DB9 connector consists of nine pins, each serving a specific purpose. These pins are responsible for transmitting and receiving data, as well as providing ground and power connections.

In this section, we will explore the process of configuring and troubleshooting the pinout of a Serial UART DB9 connection. This connection is commonly used in computer systems and other electronic devices to establish communication between different components.

The male Db9 connector consists of a total of nine pins, numbered from 1 to 9. These pins are arranged in a specific order, following a well-defined pinout scheme which allows for consistency and compatibility across various systems and devices.
