USB to serial chip is currently recognized as the most stable USB 232 chip FT232R, FT232R output signal through TTL232 6N137 high-speed optoelectronic output signals, respectively is RS485 and RS232 two kinds of signal, signal between USB and output are isolated, so as to ensure the safe and reliable work of communication.
The first chapter product introduction
A. Summary
We are generally industrial equipment communication through the computer serial port and some peripheral, but with the continuous development of computer technology, gradually from the computer serial port disappeared, which gives us the IPC staff brought great distress, the serial port to provide a stable and reliable is necessary, this product is devoted to solving this scheme and.
USBSerial chip is currently recognized as the most stable USB 232 chip FT232R, FT232R output signal through TTL232 6N137 high-speed optoelectronic output signals, respectively is RS485 and RS232 two kinds of signal, signal between USB and output are isolated, so as to ensure the safety and reliability of the communication work.
