COV-001 Isolated USB-RS422/RS485 converter
The USB-i485 module is a cost-effective way to convert RS485 or RS422 industrial buses to a USB interface. When connected to a PC USB port the USB-i485 module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application.
Muliple modules can be installed when using USB hubs thus allowing a hassle-free configuration of a multi serial system without any IRQ or DMA configuration.
1500 Vdc isolation between the USB port and RS485/RS422 protects the PC from spykes or possible misconnections in the communication bus.

The USB-i485 converter can be configured for four-wire (Full Duplex) RS422 and RS485 or two-wire (Half Duplex) networks. When operating in two-wire RS485 the data transfer control is automatically done by the converter.
Two independent and isolated RS485 networks can be supported by one USB-i485 module thus duplicating the possible number of remote devices.
