The  RS-485 to USB Converter provides a simple, low cost interface between a PC or laptop with a USB port, and 2-wire RS-485 devices. Universal Serial Bus (USB) drivers make this converter compatible with most software developed for RS-232 serial port interfaces because it appears as an RS-232 port to your software. Switching between receive and transmit is automatically controlled, RTS (request to send) is not used to control transmit. Power for the converter is taken from the USB port so no external power supply is required. A rugged design makes this converter an ideal choice for field engineers and technicians who service RS-485 2-wire equipment in an industrial environment.
