Professional grade high performance USB to RS485 / RS422 converter. If you simply want the best and need a USB to RS485 / RS422 converter which is compatible with all operating systems, including Windows 7 64-bit and Mac OS-X, and the majority of serial devices then the XS890 is what you need.
This converter is the top of the crop, and we are so confident that it will work with your system that we are offering a 30-day full refund guarantee if you for any reason can't make it work.
What makes this USB to RS485 / RS422 converter so great is the design and architecture of the circuit board with the FL232BL processor chip in conjunction with a Exar SP485E output chip; two high performance and very reliable chips.
As most of our other USB converters the XS890 is powered through the USB port so no additional power supply is required. It has bi-directional RS485 and RS422 communication with up to 600W protection against electrostatic electricity on all wires which effectively will protect the converter, your equipment and data communication against high voltage spikes and surges.
The circuitry automatically determines if RS485 or RS422 is connected to the converter, you don't need to set any jumpers or switches, simply connect your wires and you are ready to roll.
One other advantage of this converter is that it has indication LED lights for the TX and RX wires, indicating when data is present. This not only making it easy to see when communication is present but also makes troubleshooting easier.
After installing the included virtual COM drivers the created COM port will automatically show up in your operating system's Device Manager where it can be accessed as if it was a standard serial COM port. The driver software allows you to adjust multiple COM port settings such as data latency, time-outs, COM port number etc.
