NanoPower Cable
The NanoPower cable is a special device which converts 12 V to 5 V providing a power
supply for the NANO
4
and a PDA. It also translates a serial signal to match the NANO
4
signal
level and a PDA or computer signal level.
Nano Power is not a part of the package and must be purchased separately.
Connect the red and black wires to a 12 V power supply. Red is positive.
The maximum input voltage is 24 Volts.
NANOs
4
up to serial number 06099 need an additional level converter for
connection to NanoPower. This converter is included in the NANO
4
box.
The NanoPower has two plugs. On one end there is a standard USB-A connector. Please
use the included USB-A to a micro-USB cable and plug the NANO
4
on this side. Any standard
USB-A to mini-USB cable can also be used. On the other end 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 with the dedicated cable only. Do not plug any unknown cable into it as this
may damage the NanoPower circuit.
