By using a single AP, the cost of infrastructure deployment is cut in half,
with only one antenna, one feedline, and one lightning protector
required. Other cost reductions come from the system as a whole,
including reduced management requirements when using GE
MDS NETview Management System (MS) software. In addition,
entraNET offers nearly unlimited potential for future applications that
run over IP and Ethernet services.
In an IP-to-serial scenario, every Remote is sent information received by
the AP Ethernet port. Likewise, information received at the Remote
serial port is transmitted to the AP, and the AP delivers this information
through its Ethernet port in the form of an IP packet.
Additionally, the AP serial port can be used as a virtual Remote. This
means that encapsulated serial information received by the AP is sent
out the serial port of all Remotes as well as the AP serial port. The
reverse is also true, meaning that data received by the serial port of any
Remote or the AP serial port is encapsulated and sent out the AP
Ethernet port.
This arrangement can be used to connect an endpoint device at a
Repeater site without the need for an additional Remote radio.
1.3.3 DNP3 Protocol-Aware Networks
The GE MDS 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 from GE MDS.
