POWER
A three way power connector is used to connect Power+, Power– (GND), and earth. The
module requires an input voltage of 10 – 28Vdc.
Refer
to the technical specifications section
in this document.

RS232 PORT
The four way RS232 connector is used to connect the transmit (TX), receive (RX), and GND
conductors for serial communication. The shield terminal can be used for shielded cable in
high noise environments.
NOTE:
The shield of the RS232 port is internally connected to the power
connector earth. Thus when using a shield it is important to connect the Earth
terminal on the power connector to a clean earth. Failing to do this can lower
the signal quality of the RS232 communication.
NOTE:
When using a shielded cable, it is important that only one end of the
shield is connected to earth to avoid current loops. It is recommended to
connect the shield to the DNP3 Router module, and not to the other DNP3
device.

ETHERNET PORT
The Ethernet connector should be wired according to industry standards.
Refer
to the
additional information section in this document for further details.
