PL2303 Isolated USB to a RS485 RS422 DB9 COM Serial Port USB Adapter Converter
Product Features:
What is RS485?
The RS485 is a type of serial interface standard for digital communication that uses balanced differential signaling and allows multiple transmitters and receivers on a single bus. It operates on a half-duplex basis, meaning that it can transmit and receive data but not simultaneously.
What is RS422?
The RS422 is another type of serial interface standard for digital communication that uses balanced differential signaling but operates on a full-duplex basis, allowing for simultaneous transmission and reception of data over a limited distance.
What is a USB to RS485/RS422 Converter?
A USB to RS485/RS422 Converter is a device that allows you to connect a computer with a USB port to a device that uses the RS485 or RS422 communication protocol.
What is the PL2303 Chipset?
The PL2303 Chipset is a highly integrated USB to UART Serial Bridge IC that provides a simple solution for connecting any microcontroller with a UART or RS232 interface to any personal computer.
