The world's leading innovator and manufacturer of Acoustic Doppler Current Profilers (ADCPs™) and Doppler Velocity Logs uses Quatech USB to serial adapters to implement and test their systems.

Their high-tech sonar instruments measure the speed of water motion in oceans, rivers, and lakes. These devices often communicate with a host computer via an RS-232 serial connection. Our customer also develops software to control these instruments, and collect, process, and display data from them. Data from other serial devices, such as GPS, heading sensors, etc., are often incorporated into the system as well. This customer chose Quatech's USB to serial adapters because they have found that "some computers, especially laptops, have very poor performance with RS-232 serial communications. "
