The Advantages
USB-to-serial adapters are ideal for integrating older devices into modern networks. They are not only compact but also powerful. These adapters support high data transfer rates, ensuring that no information is lost. The use of RS-232 USB converters simplifies the connection between legacy devices and modern PCs. And the best part? No additional power supply is required!
Another highlight is the easy configuration of the adapters. Even users without in-depth technical knowledge can quickly set them up. Simply plug in the USB-to-RS232 adapter, and you’re ready to go.


Expansion via Bluetooth
With our Bluetooth-to-USB or Bluetooth-to-serial adapters, you can effortlessly add Bluetooth connectivity to your systems. This enables wireless data transmissions at speeds of up to 3Mbit/s. Particularly in industries where wireless sensor control and monitoring of production facilities are required, these adapters offer flexible deployment options. And since they are specifically designed for industrial applications, they are particularly robust and durable.
Industrial Applications
Serial interfaces are primarily needed where older devices need to be connected to modern systems. In areas such as automation technology, they are often used to network machine controls with higher-level systems. Here, serial interfaces ensure precise and robust real-time data transmission.
USB-to-serial adapters also play a key role in logistics. They connect barcode scanners, label printers, or older handheld devices to modern IT systems, making warehouse operations more efficient.
In medical technology, RS232 USB converters enable the connection of medical devices, such as blood pressure monitors or laboratory equipment, to modern computers. This is essential for capturing and processing measurement data digitally.
In addition to USB-to-RS232 solutions, we also offer RS-422/485 adapters, which are used for more demanding applications, such as automating production processes. These products provide stable data transmission even over longer distances.
