DESCRIPTION Pro grade USB to RS485 / RS422 converter. It easily lets you connect any RS485 or RS422 device directly to your computer's USB port. Ideal for industrial environments, the serial port converter provides 15KV ESD protection on all signal pins to protect costly and often sensitive control equipment against electrical damage. It is designed with a high performance quality processor chip (FTDI Chipset) and conversion circuitry which makes this USB to RS485 converter one of the most reliable adapters on the market. There are no IRQ & COM port conflicts, since the port do not require any additional IRQ, DMA, memory as resources on the system. Plug-and-Play, No power supply needed. Supports windows 10, 8, 7, Mac and more.
