The USB port and wireless Bluetooth connection let you download and
upload data between your computer and the NXT. If your computer has
Bluetooth capability, you can download programs to the NXT without using
the USB cable. If your computer does not have Bluetooth capability, you
must use the USB cable or install a Bluetooth USB dongle on your computer.
NOTE: Read more about wireless Bluetooth communication on page 36.
Note that ALL of the black 6-wire
cables can be used in both input
and output ports, sensors and
motors. To work, sensors MUST be
attached to the input ports (1-4)
and motors MUST be attached to
the output ports (A-C).
