USB-i485 Isolated USB to RS-422/RS-485 Converter
Robust USB converter for four-wire (full duplex) RS-422 and RS-485 or two-wire (half duplex) industrial serial busses. 1.5 kVDC isolation between PC and serial bus. Best-of-class drivers.
One of our most popular products. The Novus USB-i485 module is a cost-effective way to convert RS-485 or RS-422 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 serial port which is compatible with any existing serial communication application.
Multiple 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 RS-485/RS-422 along with ±60 VDC and 15 kV ESD bus protection provides a robust and safe connection from the PC to equipment.
The USB-i485 converter can be configured for four-wire (Full Duplex) RS-422 and RS-485 or two-wire (Half Duplex) networks. When operating in two-wire RS-485 the data transfer control is automatically done by the converter.
Two independent and isolated RS-485 networks can be supported by one USB-i485 module thus duplicating the possible number of remote devices. Each RS-485 network can operate in an independent direction allowing for full duplex RS-485 connection.
