Features: 1. This conversion module is used to convert computer USB to RS232 output, USB independent power supply design, full isolate of power signal between USB and RS232 terminal. 2. Compared with the non-using isolate conversion line, it is more anti-jamming, safer to use, and protect the computer and communication equipment. 3. This product can be used in all kinds of communication software, monitoring software, industrial control software and other application software. 4. Internal design for high-speed USB conversion chip, communication reaction rate is much higher than the mainstream FT232, strong stability, easy to use. 5. Made of high quality materials, strong, wear resistant and durable.
