The RS485USB is a RS485 USB Cable designed to provide instant Serial port expansion via the Universal Serial Bus (USB) for your Notebook PC, workstation, thin client, or server. The RS485USB includes support for RS422 to USB. The RS485USB is compatible with new and legacy RS422/485 devices. Easy to install and use without turning your PC’s power off, the RS485USB provides the scalability to quickly adapt to new USB technologies.

There is a unique I/O electric auto-control to control the direction of data transfer. No handshake signal is needed to transfer full duplex (RS422) or half duplex (RS485).

The BF-850 can be used in point to point or point to multipoint applications. In point to multipoint use, each unit adapter can connect up to 32 RS422 or RS485 interface devices.

A complete product line offers many choices to help you to expand and make your network grow with your requirements. With the USB Plug-and-Play feature, you simply plug in, follow the instructions of Install Wizard, and then you are done. You don’t have to deal with Card Slots, I/O address, IRQ jumpers, DMA and others when you are connecting the devices. The System will recognize the device and install the drivers automatically.

The RS485USB is an ideal solution for your expanding applications.
