What is USB? 
USB, or Universal Serial Bus is a connectivity specification developed by 
computer and telecommunication industry members for attaching 
peripherals to computers. 
USB is designed to free all the troubles when installing external 
peripherals. It eliminates the hassle to open computer case for installing 
cards needed for certain devices. 
It is designed to meet Microsoft Plug and Play (PnP) specification, 
meaning users can install, and hot-swap devices without long installation 
procedures and reboots. 
The I-756x USB to RS-232 or RS-485 or RS-422 converter are your smart 
and convenient accessory for connecting RS-232 serial devices to your 
USB-equipped Windows host computer. It provides a bridge connection 
with a standard DB 9-pin male serial port connector in one end and a 
standard Type-A USB plug connector on the other end. You simply attach 
the serial device onto the serial port of the cable and plug the USB 
connector into your PC USB port. It allows a simple and easy way of 
adding serial connections to your PC without having to go thru inserting a 
serial card and traditional port configuration. 
This USB to Serial adapter is ideal for connecting modems, cellular 
phones, PDAs, digital cameras, card readers and other serial devices to 
your computer. It provides serial connections up to 1Mbps of data transfer 
rate. And since USB does not require any IRQ resource, more devices 
can be attached to the system without the previous hassles of device and 
resource conflicts. 
Finally, the I-756x USB to Serial adapter is a fully USB Specification 
compliant device and therefore supports advanced power management 
such as suspend and resume operations as well as remote wakeup. The
