What is a driver?

A "driver" is software that transfers data between the SD-20 and application software
running on your computer, when your computer and the SD-20 are connected by a USB
cable. The driver sends data from your application to the SD-20, and from the SD-20 to your
application.
The SD-20 is able to operate using the "BUS power" that is supplied via the
USB cable. This means that the supplied AC adaptor is not necessary.
However, if you are using a USB hub, or if not enough power can be supplied
via USB, the SD-20 may not operate correctly. In this case, connect the
supplied AC adaptor power supply to the SD-20.
When installing the driver, you must connect the AC adaptor and turn the
POWER switch ON.
Which type of connection?
You can either use the USB cable, or use the computer cable to make a serial
connection. Depending on the type of connection you are using, install the
appropriate driver and make the appropriate settings.
