Pinout
This section describes ports 2, 3 and 4 only. See section 9.2 on page 36 for
the port 1 description.
A standard RJ12 (6P6C) connector is needed to connect to the port. The
table 6 defines the pinout and figure 27 illustrates pin ordering on connector
and plug. In most cases, only pins 1, 2 and 3 are connected. Pin 6 is used
only when you use Nesis as a power source.
Please note that output power on pin 6 is limited. The maximal current of
all ports together must not exceed 500 mA.
Never connect external power source to pin 6. This will damage the internal
circuit.
When connected device is only receiving data from Nesis, only pin 1 and 3
can be used.
