Description

This USB to serial converter is one of the most reliable serial adapters available, featuring one RS232 port fully isolated from the USB port. It is built around the FT232RL processor chip, which is one of the best serial conversion chips on the market. When choosing a reliable USB to RS232 converter, it is crucial to consider the quality of the adapter cable. Low-cost adapter cables can lead to issues related to processor quality, driver compatibility, and overall stability. Our high-quality adapter cable is designed for broad compatibility and reliability, especially with various operating systems, including Windows.

Isolation is made using the ADM3251E chip from Analog Devices which offers 2.5 kV fully isolated (power and data) communication with a data rate of up to 460 kbps. ESD protection on the TX and RX pins is up to ±8 kV contact discharge and ±15 kV air gap discharge. This is a very effective solution for protecting your USB port and serial device against most types of power surges, static electricity, voltage spikes, and transients. Ideal for industrial applications, and suited for operation in electrically harsh environments or where RS-232 cables are frequently being plugged and unplugged.

The enclosure is made of sturdy sheet metal that won’t easily break. Included with the converter are DIN mount brackets so you can easily mount this converter on a standard DIN rail. Included are also screw mount brackets so it can be mounted on a flat surface using screws.

The converter is powered through the USB port so no external power supply is needed. LED indication lights indicate when data is sent and received.

What is a USB to Serial Converter?

A USB to Serial converter is a versatile device that bridges the gap between modern USB ports and legacy serial devices. By converting USB signals to serial signals, this adapter allows you to connect older serial devices, such as digital cameras, GPS systems, and PDAs, to contemporary computers that lack built-in serial ports. This seamless connection ensures that you can continue to use your trusted serial devices with the latest USB-enabled systems, enhancing their functionality and extending their lifespan, thanks to the right choice of USB serial adapters.

Benefits of Using a USB to Serial Converter

Using a USB to Serial converter offers numerous advantages, making it an essential tool for anyone needing to connect legacy serial devices to modern technology. These converters provide a reliable and cost-effective solution for integrating serial peripherals, such as a digital camera, with USB-enabled systems. They enable the use of serial devices with contemporary computers, laptops, and tablets, allowing for the connection of multiple serial devices to a single USB port. This not only frees up valuable serial ports for other uses but also ensures that your legacy equipment remains functional and relevant in today’s digital landscape.

Key Features to Consider

When selecting a USB to Serial adapter, there are several key features to consider to ensure you find the right one for your needs. Here are some of the most important factors to consider:

  1. Compatibility: Ensure the adapter is compatible with your operating system, including Windows, Mac, and Linux. Also, check if it supports your specific serial device or peripheral. This is crucial for seamless integration and functionality across different platforms, whether you’re using Windows XP, Windows Vista, or even Windows Server.

  2. Data Transfer Rate: Look for an adapter with a high data transfer rate, such as up to 921.6 Kbps, to ensure fast and reliable communication between your serial device and computer. High data transfer rates are essential for applications that require quick and efficient data exchanges, such as connecting digital cameras or ISDN terminal adapters.

  3. USB Port: Consider an adapter with a USB-A connector, which is widely compatible with most computers and laptops. This ensures that you can easily connect the adapter to a single USB port on your device without any compatibility issues.

  4. Serial Port: Ensure the adapter has a DB9 serial port, which is the most common type of serial port used in serial devices. This type of port is essential for connecting a wide range of legacy serial devices, from modems to cellular phones.

  5. Cable Length: Choose an adapter with a suitable cable length, such as 35 cm, to ensure easy connection and minimal clutter. A well-sized cable allows for flexible positioning of your serial device without creating a tangled mess.

  6. Power Supply: Consider an adapter that is powered individually by the USB 2.0 port, eliminating the need for an external power supply. This feature simplifies the setup process and reduces the number of cables required, making it more convenient to use.

  7. Reliability: Look for an adapter with a robust design and anti-EMI capability to ensure reliable data transfers and minimize errors. A durable and well-shielded adapter can withstand the rigors of frequent use and provide consistent performance.

  8. Plug-and-Play: Opt for an adapter with a plug-and-play feature for hassle-free setup and installation. This allows you to quickly connect your serial device to your computer without the need for additional drivers or complex configurations, ensuring a smooth and user-friendly experience.

By considering these key features, you can select a USB to Serial adapter that meets your specific needs and ensures reliable and efficient communication between your serial devices and modern computers.

Applications for USB to Serial Converters with Serial Devices

USB to Serial converters, also known as serial adapters, are incredibly versatile, finding applications across various industries and use cases. They are commonly used to connect legacy serial devices to modern computers, bridging the gap between old and new technology. These adapters are essential for connecting serial peripherals such as modems, printers, and serial mice to contemporary systems.
