FT232R chipset provides single chip USB to asynchronous serial data transfer interface. Works with all Windows and Mac OS versions Visual indication of Power and Tx/Rx data traffic via LEDs in the transparent USB connector Every cable is built to last for years with high quality industrial grade materials. The cable works with all Windows and Mac OS versions including the latest Windows 10 and Mac OS X 10.12(Sierra). The USB-RS485 cable is a USB to RS485 levels serial UART converter cable incorporating FTDI's FT232R USB to serial UART interface IC device which handles all the USB signaling and protocols. The cable provides a fast, simple way to connect devices with an RS485 interface to USB. This cable has 6 outputs: GND(Black), Data-(Yellow), 5vPower(RED), Terminator1(Brown), Data+(Orange), Terminator 2(Green). In the cable, there is a 120R terminal resistor resistor connected in between Terminator 1 and Terminator 2.
