FTDI chip USB to RS485 cable with TX / RX LEDs 6 feet to the cable end adapter USB RS485 WE compatible RS485 adapter cable with driver The USB RS485 converter cable provides a serial USB to RS485 interface with user defined end connections. The entire USB to RS485 translation protocol is processed by the electronics in the cable ESD protection for RS 485 I / O plusmn15kV Human Body Model (HBM) plusmn15kV EN61000 4 2 air gap discharge plusmn8kV EN61000 4 2 contact discharge EIA / TIA 485 communication interface with low power consumption. The FT232R chipset offers a single chip USB interface for asynchronous serial data transmission. Works with all Windows. Visual display of the power and Tx / Rx data traffic via LEDs in the transparent USB port Each cable is designed for a long service life with high quality, industrial grade materials. The cable works with all versions of Windows and for Mac OS, including the latest Windows 10 and for Mac OS X 10.12 (Sierra). The USB RS485 cable is a serial UART converter cable at USB to RS485 level that contains the FTDI IC device FT232R USB to serial UART interface, which processes all USB signals and protocols. The cable offers a quick and easy way to connect devices with an RS485 interface to USB. This cable has 6 outputs: GND (black), data (yellow), 5 V power (RED), terminator 1 (brown), data + (orange), terminator 2 (green). There is a 120R connection resistor in the cable between termination 1 and termination 2.
