The USB-i485 Converter 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 Converter is automatically detected and is installed as a native COM 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 RS485/RS422 protects the PC from spikes 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 Converter thus duplicating the possible number of remote devices.
Virtual Comm Port Drivers(available via download)
Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.
