Attention: Not all USB 2.0 devices operate at High Speed baud rates. If rates above 12Mbps are needed ensure that both the device and the computer are certified High Speed.Finding a new computer today that will ship with the once standard DB-9 and DB-25 connections, and that will communicate with your RS-232 and RS-422/485 devices is a significant challenge. As the high-speed Universal Serial Bus (USB) has progressively dominated the consumer market, these slower and more cumbersome connections have become obsolete to the masses. Following typical supply and demand procedures, PC manufacturers have simply stopped providing them as standard hardware, replacing them with USB components.This shift in the marketplace represents somewhat of an obstacle for industrial players, as most of their current electronic equipment utilizes RS-232 and RS-422/485 interfaces to communicate with their computer systems.
