3.6 NanoPower cable
The NanoPower cable is a special device which converts 12V to 5V providing a power supply
for the NANO
3
and a PDA. It also translates a serial signal to match the NANO
3
signal level
and a PDA or computer signal level.
Connect the red and black wire to 12V power supply. Red is positive.
Maximum input voltage is 24 Volts.
The NanoPower has two plugs. On one side there is a standard USB-A connector. Please
use the included USB-A to mini-USB cable and plug the NANO
3
on this side. Any standard
USB-A to mini-USB cable can also be used. On the other side there is an RJ45 plug. This
plug is designed for a PDA or a computer.
The RJ45 plug is NOT designed in accordance with the IGC standard. It can be
used only with a dedicated cable. Do not plug any unknown cables in to it as this
may damage the NanoPower circuit.
Pin description on the NanoPower RJ45 is given in the picture below.
