USB – Universal Serial Bus
A convenient and reliable way to combine
your new PC and legacy equipment
Isolators
Converters
USB supports high data rates, plug-and-play connections, noise
immunity, and “hot swappability” providing an easy
connection to a wide variety of multimedia and network USB
devices.
But what if you still have good equipment designed to use
RS-232, RS-422 or RS-485 serial communications? How can you
monitor and control it from a modern USB equipped PC?
B&B Electronics has your answer - converters, adapters, cards,
hubs, surge protectors, boosters and isolators that connect your
USB PC to your legacy equipment so you can use both to your
greatest advantage.
Universal Serial Bus is a serial protocol and physical layer link.
Data is transmitted differentially on one pair of wires,
providing relatively good noise immunity. Another pair carries
DC power to downstream devices, allowing many low power
devices to be bus powered.
