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 spikes or possible misconnections in the communication bus.
Description
The USB-i485 module is a cost-effective way to add an industrial RS485 or RS422 serial port to your PC using a standard USB port. When connected to a PC USB port the USB-i485 module is automatically detected and installed as a native COM port compatible with ANY existing serial communication application. 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 handled automatically (autogating) by the converter.
Two independent and isolated RS485 networks can be supported by one USB-i485 module thus doubling the number of remote devices that can be connected. Multiple modules can also be installed when using powered USB hubs, thus allowing a hassle-free configuration of a multi serial system without any IRQ or DMA configuration. 1500vDC isolation between the USB port and RS485/RS422 protects the PC from spikes and other possible transient voltages on the communication bus.
Software and USB connection lead included.
