Network Setup
Both the single-channel SpeedNet SDR Radio and the dual-channel SpeedNet 4x4 Radio
are versatile smart grid-enabled wireless devices that have been designed specically for
power distribution automation (DA), SCADA, and distributed-generation applications.
SpeedNet SDR Radios provide wireless connections between two or more Internet
Protocol (IP) or serial devices. Application devices, such as the S&C IntelliRupter®
PulseCloser® Fault Interrupter, can be connected to a SpeedNet SDR Radio. As routers,
SpeedNet SDR Radios route IP data between separate Ethernet subnets. Data are routed
between the Ethernet subnets over a common IP-based wireless network. Route information
can be entered manually, or it can be handled automatically by the SpeedNet SDR Radio’s
proprietary enhanced version of the Ad hoc On-demand Distance Vector (AODV) routing
protocol.
Prior to implementing a SpeedNet SDR Radio network, you should plan the IP addressing
scheme. The use of private IP addresses is recommended when designing a SpeedNet SDR
network. The diagram in Figure 2 shows a sample IP address scheme for a simple three-node
network using private IP addresses.
Figure 2. Multi-node SpeedNet SDR network.
The SpeedNet SDR Radio network shown in Figure 2 contains three Ethernet segments.
The first segment uses the 192.168.1.0 Class C subnet, encompassing a range of addresses
from 192.168.1.1 to 192.168.1.254. The second segment uses the 192.168.2.0 Class C subnet,
encompassing a range of addresses from 192.168.2.1 to 192.168.2.254. The third segment
uses the 192.168.3.0 Class C subnet, encompassing a range of addresses from 192.168.3.1
to 192.168.3.254.
The wireless network in the example uses the 192.168.202.0 Class C subnet. This subnet
is different from the subnets used for the Ethernet segments. The wireless interface of the
SpeedNet SDR Radio from the Source Node is assigned an address of 192.168.202.1. The
wireless interface of the SpeedNet SDR Radio from the Repeater Node is assigned an address
of 192.168.202.2. The wireless interface of the SpeedNet SDR Radio from Destination Node
is assigned an address of 192.168.202.3.
In this example, each SpeedNet SDR Radio host ID is 1 (as in 192.168.3.1), while the
connected application device uses a host ID of 2 (as in 192.168.3.2). Following a
numbering scheme such as this will make it easier to keep track of which IP addresses are
assigned to each device.
Note: All SpeedNet SDR Radios, regardless of their role within the network (i.e. source,
destination, repeater), must use unique IP addresses for their Ethernet and wireless inter-
faces. All the SpeedNet SDR Radios on the same mesh should have wireless IP addresses
in the same subnet. All the SpeedNet SDR Radios on the same mesh should have different
Ethernet subnets.

planning.

Conguration
The configuration and management of a SpeedNet SDR Radio network is achieved using
a standard Web browser and entering the IP address of the radio. The default IP address of
a SpeedNet SDR is set to 192.168.0.3 at the factory. Note that your PC IP address must be
on the same LAN segment of the SpeedNet SDR radio.
Open up a Web browser and enter the IP address of the radio. Again, the default IP address
of a SpeedNet SDR is set to 192.168.0.3 at the factory.
Authentication requires a username and password. Contact S&C for these credentials.
See Figure 3.
Figure 3. Authentication Required dialog box.
Enter a Device Name for the radio in the text box on the Main screen, and click on the
Save button to save. See Figure 4.

Network
Figure 6. The Network>Interface Settings screen.
Figure 5. The Network>VLAN screen.
Navigate to the Interface Settings screen, as shown in Figure 6.
Interface—This is the list of the physical interfaces within the radio.
Mode—There could be a Routed or Bridged mode. Routed is the normal mode of
operation intended for AODV mesh radio systems. Other configurations support Bridged
operation with VLAN IDs.
Description—This is an alphanumeric name to be associated with the physical port.
IP address—This is the IP address of the physical port.
IP Mask—This is the subnet mask of the physical port.
Note: On a given SpeedNet SDR Radio mesh, the configurations of all the Ethernet
interfaces must differ on each radio so there is no overlap between the Ethernet port
subnets, or between the Ethernet port subnets and the wireless subnet.
MAC Address—This read-only field displays the unique Media Access Control (MAC)
address for each of the SpeedNet SDR Radio interfaces. No two network devices will
use the same MAC address.
Navigate to the Network>VLAN screen, as shown in Figure 5, and congure the VLAN(s) to be
created in the radio. A VLAN may be added and dened. Enter the VLAN Id and Description,
and click on the Save button.
NOTE: VLANs are not supported with AODV mesh networks.
VLAN
Interface Settings

S&C Instruction Sheet 1075-530 7
Network
PVID—This is the primary VLAN ID associated with a physical Ethernet port. By con-
vention, untagged Ethernet frames entering the radio via a physical Ethernet port are
assigned to the native VLAN specified for that port. Any untagged frames leaving an
Ethernet port are also associated with the port’s native VLAN. The default setting is 1.
Note:VLANs are not supported with AODV routing protocol.
Note:VLANs are not supported with AODV mesh radio configuration.
Allowed VLANs—This list is used in combination when the Allowed VLANs is set to
LIST to specifically identify which VLANs can enter or leave the radio over a physical
Ethernet port or wireless radio interface.
VLAN Port Tagging—This value controls the VLAN tagging behavior for an Ethernet
port. The default is the None setting.
When set to the None setting, an Ethernet port does not add VLAN tags to any frame
leaving the port, and only untagged frames are allowed to enter the radio. One exception
to this rule is that tagged frames belonging to the native VLAN are accepted by the radio.
All packets entering and leaving the radio are associated with the native VLAN. Note: As
above, Port Tagging is not supported with AODV mesh radio systems.
When set to the Exclude Native setting, the port acts as a VLAN trunk and will tag all
frames leaving the port, except those belonging to the native VLAN. Traffic entering the
port can be tagged or untagged, with all untagged frames automatically being associated
with a port’s native VLAN.
When set to the All setting, the port acts as a VLAN trunk and will tag all frames leaving
the port, including those belonging to the native VLAN. Traffic entering the port must be
tagged. Any untagged frames entering a port are dropped.
Default IP Gateway—Enter the IP address of the next-hop gateway that will act as the
default gateway for this SpeedNet SDR Radio. The gateway will be the IP address of the
wireless interface of a SpeedNet SDR Radio. NOTE: This Gateway address is not typi-
cally configured for when AODV routing is enabled. The Gateway used for AODV routing
is configured on the AODV: Settings page.
Click on the Save button to save your changes or the Apply button to make the new
changes active. Note: Depending on your computer’s configuration, it will most likely be
necessary to change or add an IP address on your computer to be on the radio’s new subnet
after the new settings are applied.

Network
Figure 7. The Network>Static Routes screen.
The screen shown in Figure 7 displays the Static Routes of each installed radio.
• Network ID—This is the destination network for the route that is being created. To
enter a static route for a device with an address of 192.168.200.1 and a subnet mask
of 255.255.255.0, the Network portion of the route entry should be 192.168.200.0.
• Network Mask— This is the subnet mask for the destination network for which the
route is being created.
• Gateway IP— This is the next-hop gateway of the destination network for which the
route is being created. The gateway will be the IP address of the wireless interface
of a SpeedNet SDR Radio.
• Add—After entering the details of the static route, click the Add button to add the
route to the route table.
• Save—Click the Save button to save all information.
Note:Static routes must not be configured when AODV automatic mesh routing is
enabled.
Static Routes

S&C Instruction Sheet 1075-530 9
Network—AODV
Figure 8. The AODV>Settings screen.
The Main screen provides a list of tabs that can be used to congure the routing performance
of a SpeedNet SDR Radio. Selecting a tab will provide a list of congurable options.
The AODV Settings tab, shown in Figure 8, is used to enable, disable, or configure
the embedded ad hoc (mesh) routing protocol. The embedded ad hoc routing protocol is a
customized version of Ad-hoc On-demand Vector (AODV). The following parameters can
be configured:
Off—Selecting the Off setting disables the automated mesh networking protocol. When
disabled, static routes must be entered manually on the Static Routes tab for all end-
points this radio needs to reach. No combination of automatic AODV routing and static
routing is supported.
AODV—Selecting AODV enables the embedded mesh networking protocol, allowing net-
work routes to be created and maintained automatically among SpeedNet SDR Radios.
All radios in the network must enable AODV to use the feature. Selecting AODV is recom-
mended for ease of configuration, robustness to radio failure, and ease of adding radios
to the mesh. The remaining configuration options on the Ad Hoc Settings tab pertain
specifically to the mesh networking protocol.
Active Route Timeout—The Active Route Timeout parameter determines how long a
SpeedNet SDR Radio should wait for an inactive data communication route to be removed
from the route table. Each time an IP packet is sent over a specific route, a timer begins
counting down. If the timer expires before another packet is sent, the route is considered
inactive and is removed from the radio’s route table. The Active Route Timeout value
determines the length of this timer. The value of this parameter is measured in minutes
and has a default value of 30 minutes. In SCADA polling applications, a timeout value
greater than the polling interval is recommended. Note that a route is defined by the IP
address of the two endpoints. A given pair of SpeedNet SDR Radios may have several
separate routes between them, for example serving different devices on the radios’ Eth-
ernet ports. As such, activity on one route between two radios does not preserve other
routes between the two radios for traffic with different source/destination IP addresses.
Hello Interval—This setting determines how frequently the SpeedNet SDR Radio
broadcasts a neighbor beacon message (hello message). Smaller Hello Interval values
increase the wireless network’s responsiveness to routing changes but do so at the
expense of creating additional network communication overhead. Larger Hello Interval
values decrease the wireless network’s responsiveness to routing changes but reduce
excessive wireless traffic in the process. This value is measured in seconds and has a
default value of 30 seconds.
Allowed Hello Loss—This value determines the number of consecutive Hello mes-
sages that, when missed, constitutes a link failure that will lead to a new route request
for routes incorporating the link that failed. The default value is 0. Setting this value too
AODV Settings

10 S&C Instruction Sheet 1075-530
low can cause unnecessary route generation when a Hello message was lost due to a
temporary circumstance (e.g. a burst of interference or a packet collision). Setting this
value too high can cause excessive data loss in a route that is no longer viable due to the
persistent failure of a link in the route.
Net Diameter—This setting determines the maximum number of wireless hops between
the source and destination nodes, specifically, the maximum number of hops that a route
request message can travel. This value has a default setting of 5 hops. The Net Diameter
should be set to at least the maximum number of hops expected for application traffic.
If the Net Diameter is set too low, then route creation may fail due to route requests
never reaching the desired endpoint. If the Net Diameter is set marginally too low, then
primary route creation may succeed, but creation of a secondary route may not succeed
in the case of a link failure along the primary route. If the Net Diameter is set too high,
then route requests may propagate needlessly to too many radios, generating excessive
overhead. Setting the Net Diameter too high is a more critical issue in highly connected
mesh deployments than in linear deployments. In mesh deployments, the overhead
incurred by the Net Diameter can increase as the square of the diameter.
Node Traversal Time—This value provides an estimate of the time required for a
packet to traverse one wireless hop. The value affects how long a SpeedNet SDR Radio
waits before resending a route-request packet. This value is measured in milliseconds
and has a default value of 800 msec.
ARQ Minimum Time—When a message has not been successfully delivered to a des-
tination radio as defined by the number of attempts configured on the Master Repeat
Addr setting on the Radio Network Settings screen, the message is dropped and a timer
is started. The ARQ Minimum Time is the sample period from the start of the timer.
ARQ Maximum Time—This is the reset timer. The time in which the radio memory is
cleared of an unsuccessful message to a destination radio.
ARQ Percent—This is the percentage of messages that are not successfully delivered
to a unique destination in the sample period defined by the ARQ Minimum Time.
Note: The above ARQ setpoints allow a configurable means to determine a number of
successive, unique packet-delivery retries prior to terminating a route. When this percent-
age of successive retries is reached, a radio node is able to know more quickly that its next
hop radio neighbor is no longer available to route packets, and a route will be built around
that unavailable neighbor if there is another valid neighbor.
This configuration parameter is useful to balance the identification of an unavailable
neighbor with packet-delivery success rates so that more expedient routing may be per-
formed around an unavailable node.
