DNP3 Protocol-Aware Networks The implementation of Distributed Network Protocol 3 (DNP3) allows the transfer and routing
of DNP3 messages between serial devices, while also supporting the conversion to an IP
Ethernet network. As DNP3 messages are routed through the system, the APs “learn” the
locations of all end devices, regardless of whether they are configured for serial or Ethernet
communication, eliminating the need to configure their individual locations.
DNP3 devices with an Ethernet or IP interface can be connected to a transceiver in one of two
ways:
• To the Ethernet port of an AP radio
• To the Ethernet port of a Remote radio
DNP3 devices with a serial RS-232 interface can be connected to a transceiver in one of two
ways:
• To the serial port of an AP radio
• To the serial port of a Remote radio
The capability for DNP3 message routing is optional for the transceiver. An Authorization Key
is required to enable this functionality, and is available for purchase.
NOTE: Detailed information on the DNP3 protocol is available on the DNP Users’ Group Web
site at www.dnp.org.
