Wave USB to 4 Channel Serial Converter

The Wave USB to 4 Channel Serial Converter is an industrial-grade converter with an FT4232HL chip. It supports USB to 4 multi-functional serial ports, including TTL, RS485, RS232, and more. With isolation, TVS protection, and a robust metal case, it ensures fast, stable, and secure communication. The industrial design supports wall-mount installation, and LEDs indicate power and transceiver status. Compatible with various operating systems, it's ideal for expanding or debugging industrial serial port devices, providing a versatile and reliable solution.
