Usb uart adapter cable

Types of USB UART adapter cable

Many modern devices need the USB UART adapter cable to connect the universal asynchronous receiver-transmitter (UART) devices to the universal serial bus (USB) ports. Terminal, instrumentation, and industrial devices often use UART for asynchronous serial communication.

When looking for a UART cable to buy in bulk, it is important to look at the different types of cables depending on the structure and signal variations:

• Standard USB to Serial Adapter

  This type of cable comes with a USB connector that is plugged inside the USB port of a modern laptop and a serial connector that is plugged into devices that have a serial port. It can connect blow 5V TTL levels to RS-232 or similar levels, allowing the conversion of digital signals between the computer and serial device.

• USB to TTL Serial Cable

  This cable type has a USB connector on one end and a 4-pin or 6-pin connector cable that allows it to be plugged directly to other serial devices that do not have a serial port. The direct connection to PCB or other devices is possible. This cable is mainly used for microcontroller programming, prototype development, and projects.

• FTDI based USB Serial Cable

  Cables that are based on the FTDI chipset are known to be more reliable and are often used for professionals. The UART adapter cable with an FTDI chip can convert signals with a stable voltage level, making data transmission clear, especially in environments with electrical interference.

• PL2303 based USB Serial Cable

  This type of cable is more cost-effective but can have lower performance. It can be used to connect devices that do not require fast data transfer, like mice and keyboards.

• USB to RS-485/RS-422 Serial Converter

  Devices that require the RS-485 or RS-422 standard for communication can use this cable. It can connect to devices like industrial machinery and security systems.

• Wireless USB to Serial Adapter

  This cable represents the future as it does not require a physical connection between modern laptops and devices that use serial communication. The Wireless USB to Serial adapter allows the user to connect with serial devices over Bluetooth or Wi-Fi.

Function and features

A USB to UART adapter can be used for communicating with devices like modems and GPS receivers. It is popular among crafters, hobbyists, and engineers. The following features and functions are common to USB UART adapter cables:

• Serial Communication

  The primary function of a USB to UART adapter cable is to enable serial communication between devices. The cable converts USB signals to Universal Asynchronous Receiver-Transmitter (UART) signals. UART is a hardware communication protocol that uses serial data format. This allows devices with UART interfaces, such as older modems, serial mice, and GPS receivers to connect to a computer via a USB port.

• Data Transmission:

  The USB UART cables facilitate data transmission between devices for data exchange, system configuration, debugging, and programming of embedded systems. They are also used to transfer data between computers and microcontroller-based devices like Arduino and Raspberry Pi.

• Connectivity:

  These cables connect a USB port to a serial port. The cables have a USB connector that plugs into a USB port on a computer, laptop, or power source. The other end of the cable has a connector with a serial port that connects to the device with a UART interface.

• Driver Installation

  Most USB adapter cables need proper drivers for the operating system to recognize them. The adapter converts signals between two types of communication protocols that work in different ways. A driver installs software so that computers can understand how the cable works. The driver enables plug-and-play connectivity to make it easy for users to install and use the cable after downloading the right driver.

• Baud Rate Configuration

  The baud rate is the speed of data transmission. Users can configure the baud rate to match the requirements of the device. Common baud rates include 9600, 19200, 38400, 57600, and 115200 bps. Users can adjust the baud rate to optimize performance for various applications.

• Error Handling

  USB to UART adapter cables usually have error checking mechanisms to ensure proper data transmission. These include checks for framing errors, parity errors, and data corruption. The adapter detects errors during data transmission and takes steps to correct them to ensure reliable communication.

• Wide Compatibility Standards

  USB to UART cables are compatible with many operating systems, including Linux, Windows, and macOS. They support various communication protocols such as RS232, RS485, RS422, and Modbus RTU.

Applications of USB UART adapter cables

The USB UART cable can be useful for various industries. Here are some the cable's applications:

• Data Acquisition and Sensors:

  This cable connects to a USB port and transforms signals from serial sensors or data-loggers with UART. Industries that rely on sensors to get data on temperature, pressure, or other physical parameters can use the cable to convert the signal and transfer it to a PC. This will enable real-time monitoring, analysis, and data logging.

• Medical Devices:

  Some medical devices use UART to communicate. Medical devices such as glucometers, heart-rate monitors, and other mobile devices now use USB cables with UART to work. Medical practitioners can track, acquire, and store patient diagnostics and medical records data electronically by connecting such devices to a USB cable.

• Robotics and Control Systems:

  Robotics systems use UART for communication. Robots, drones, and other automated systems can use the USB cable to replace their UART links. This can help with real-time control, data transfer, system monitoring, and adjustment. Essentially, users can control robots and automated machines via the cable.

• Industrial Automation:

  The USB adapter cable can connect tools, sensors, and machines to computers. This can boost productivity and enhance operational performance by enabling real-time monitoring and data transfer essential for automation systems.

• Charging Devices:

  Other USB UART cables can charge devices, such as smartphones and tablets. They comply with USB power specifications to deliver maximum voltage and current to devices that accept charging through a USB connector. They are convenient because they perform both data transfer and charging functions.

• Firmware Updates:

  The adapter cable can also upgrade firmware on devices like gaming consoles, smartphones, and tablets. Users can connect the device to a computer with a USB cable to download and install firmware updates if the normal update channel is not working.

• Custom Development Projects:

  Enthusiasts that enjoy building electronic projects and doing DIY work can also use the USB cables. They are flexible and can be integrated into various custom projects to add a USB port for easy connectivity.

The USB to UART adapter cable is useful for connecting devices to a computer through a USB cable. Its versatility means it can be used in a number of applications, from industrial automation to personal DIY projects.

How to choose USB UART Adapter Cables

Various factors should be considered when choosing a USB to UART cable to get one that suits specific needs. The following are some of them;

• Connector type: The connector type that will fit the device is the primary factor when choosing a USB to serial cable. To connect the cable, one has to ensure that the adapter's USB plug fits into the device's port.
• Chipset: When choosing USB to Serial Cables, the Chipset should be put into consideration. This is because the chip that the USB cable uses can significantly affect its compatibility and performance.
• Length: The intended use of the cable is the primary factor that influences the length of the cable to be chosen. Users should choose short cables to connect to nearby ports. If the user intends to connect to ports that are far away, longer cables should be chosen.
• Purposes: Different cables are made for different purposes. When choosing a cable, users should consider the features required for their intended purpose. For instance, users who need a cable suitable for outdoor use should go for cables made with waterproofing features.
• Price: Price is a common factor that affects any buying decision. When choosing these cables, buyers should choose cables that fit their budgets while meeting the required features and quality.
• Reviews and reputation: The reviews and reputation of cable manufacturers should influence the buying decision. Buyers should go for cables from manufacturers with positive reviews and a good reputation in producing reliable and high-quality electronics.
