USB Converters - Essential Components for Today's Industrial Connections

From B&B Electronics

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.

Network Routers
Network routers are protocol-dependent devices that connect subnetworks, or that break down a large network into smaller subnetworks.
Network Transceivers
Network transceivers connect nodes and send and receive signals. In Ethernet networks, they are called medium access units (MAU).
Network Gateways
Network gateways interconnect networks with different, incompatible communication protocols. They perform a Layer-7 protocol-conversion to translate one set of protocols into another (for example, from TCP/IP to SNA or from TCP/IP to X.25).
Access Points
Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.
