Product Information

Product Description

The BF-850 is a RS485/RS422 to USB adapter designed to provide instant connection from Serial interface to PC or server. The device follows USB/RS422 and RS485 standards and policies and is easily installed without turning your PC’s power off. 

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 multipoint applications. In multipoint use, each unit adapter can connect up to 32 RS422/RS485 interface devices.

With the USB Plug-and-Play feature, you simply plug in, follow the instructions of Install Wizard. 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.
