About This Manual .............................................................

   

 

The BB-USR604 is an industrial grade, four port, isolated USB to serial converter. It enables any host USB port to 
provide multiple RS-232, RS-422 or RS-485 two or four-wire serial interfaces. 

The BB-USR604 converter supports USB 2.0 high-speed data rates of 480 Mbps. The upstream and downstream 
sections are isolated to 2000 Volts. Industrial features such as a rugged metal case, versatile mounting options, 
high ESD protection, wide temperature ranges, and high retention USB connectors set this device apart from other 
USB to serial converters.
