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.
Network—AODV

S&C Instruction Sheet 1075-530 11
Network—AODV
Link Threshold—The Link Threshold value determines the signal level above which
routes are selected strictly on a minimum hop count basis. If routes within the Network
Diameter restriction comprising solely links with signal strength above the Link Thresh-
old are found, then the route with the minimum hop count will be selected from among
these possible routes. If no route within the Network Diameter restriction comprising
solely links with signal strength above the Link Threshold is found, then the route with
the strongest minimum link signal strength will be selected. If multiple routes with the
same minimum link signal strength are found, then the route with the minimum hop
count will be selected from among those routes. The default Link Threshold value is
-77 dBm. Setting the Link Threshold value too high can cause the mesh to use longer-
than-necessary routes. Setting the Link Threshold value too low can cause the radios
to encounter excessive errors and link-level retries along the selected route. Also note
that only bidirectional links wherein hello beacons have been successfully exchanged
between both endpoint radios can be used in SpeedNet SDR Radio routes.
Route Refresh Time—Once a route has been established, periodic route updates are
broadcast to the wireless network. The Route Refresh Time determines how frequently
route-update messages are broadcast. The default value is 180 minutes. If the Route
Refresh Time is too short, there may be excessive overhead on the radio network in
carrying the route updates. If the Route Refresh Time is too long, the network may be
slow to optimize routes when better routes become available (e.g. when a new repeater
is added or when temporary interference abates).
LLP (Local Link Preference) Timeout—A SpeedNet SDR Radio normally attempts to
find the path between nodes that has the fewest number of hops. However, sometimes the
shortest path is not always the optimal one due to conditions such as RF interference,
line of sight impediments, multipath propagation, and network congestion. If Local Link
Preference is enabled and a radio experiences inability to deliver messages through a
given neighboring node, a SpeedNet SDR Radio will attempt to avoid that neighbor, if
alternate neighbors are available to deliver the messages, when building future routes.
It should be noted that LLP can coexist with the Blacklisting feature. Blacklisted IPs
remain blacklisted regardless of LLP state. LLP does not blacklist an IP address, it simply
places the offending next hop neighbor into a “penalty box” so it is not used until a time
that is configurable.
The LLP Timeout parameter specifies when a neighbor who had been put in the LLP
blacklist is made available as a routing option. Setting LLP Timeout to 0 effectively dis-
ables LLP. When LLP is enabled, the recommended value for LLP Timeout is 1440 minutes
(1 day). Factory Default is set to 0.
AODV Gateway IP—The gateway address is the IP address of the router that the Speed-
Net SDR Radio will use as its gateway to the corporate LAN, Internet, or other routable
network external to the wireless networks.
AODV Gateway—This feature allows a SpeedNet SDR Radio in a network to act as a
gateway between the wireless network and the Internet or other routable network. Placing
a check mark in the Enable AODV Gateway check box enables this feature and provides
the additional configuration options detailed below. The Enable AODV Gateway option
should only be enabled on the SpeedNet SDR Radio that will act as the gateway for the
rest of the wireless network.
Save—Saves changes made to the configuration of the AODV Settings tab. Changes
will not be saved if you change to a different configuration tab without first clicking on
the Save button.

12 S&C Instruction Sheet 1075-530
Network—AODV
The AODV Networks table provides the list of wireless networks that are able to use the
SpeedNet SDR AODV Gateway Radio as a gateway to other networks. See Figure 9. The
table must be populated to include all of the Ethernet subnets of all SpeedNet SDR Radios.
All wireless networks used by the radios must also be congured in this table. This list of
networks determines which route requests the AODV Gateway radio should not answer
(in other words, what IP trafc the AODV gateway should not attract and forward to the
gat eway address).
Network ID—Defines the network(s) for which the SpeedNet SDR gateway radio will
act as the gateway.
Network Mask—The Subnet Mask (Network Mask) works in conjunction with the
Network ID to define the SpeedNet SDR Radio networks that have a need to use a default
gateway.
Note: The above networks may be summarized or configured as a range that covers all
of individual networks on the wireless side of the AODV Gateway radio.
Add—After entering a Network ID and Network Mask, click on the Add button to add
the wireless network to the table.
Delete—To delete a wireless network from the table, select the wireless network from
the table and then click on the Delete button.
Save—Saves changes made to the configuration of the AODV Network tab. Changes

Save—Saves changes made to the configuration of the AODV Blacklist tab. Changes
will not be saved if you change to a different configuration tab without first clicking on
the Save button.
AODV Blacklist The AODV Blacklist feature is used to prevent routing through SpeedNet SDR Radios that
qualify as valid neighbors, but are neighbors that you do not want to use as next hop links
for that particular radio address. See Figure 10. One reason to exclude a neighbor is that it
may have a permanent or transient line-of-sight impediment, which results in poor packet
delivery success over a given radio link. Further, that radio may not have a transmission
problem from a different neighbor.
The AODV Blacklist address table is limited to a total 36 radio addresses.
If you plan to make use of the Blacklist feature to prevent the use of poorly perform-
ing neighbor links, contact Power Systems Solutions for assistance to identify the poorly
performing links and properly apply the AODV Blacklist configuration.

Radio
Navigate to the Radio RF Settings screen. See Figure 13.
Enter the master and slave frequencies to use. Note: On an AODV mesh system, these
two frequencies will be the same.
Master Tx Freq—The operating channel of the radio. Enter the frequency in MHz.
Slave Tx Freq—The operating channel of the slave radio. Enter the frequency in MHz.
Note: On an AODV mesh radio system, these two frequencies will be the same.
Transmit Power—Enter the transmit power in milliwatts.
Transmit Rates—Configure the Transmit Rate. The ideal setting is a function of dis-
tance, throughput required, transmit power, and radio noise in the area. In AODV routing
installations, all radios must be configured to the same transmit rate. Transmit rates
that are shown reflect the available rates for FCC, IC, and ETSI. Only the transmit rates
that are certified for the market where the radio was initially sold will appear.
Master Transmit Rates—This setting is used for multispeed multipoint radio configu-
rations and not used in AODV mesh radio systems.

Navigate to the Radio Network Settings screen. See Figure 14.
Description—Enter the alphanumeric name for the radio interface.
Network Type—The options are Point to Point, Point to Multipoint, and CSMA Peer to
Peer. CSMA Peer to Peer is the setting to be used for AODV mesh networks.
Mode—The options are Master or Slave. Master is to be selected for AODV mesh networks.
Enable Repeaters—This is a feature of point-to-multipoint systems. Select the No
option for AODV mesh networks.
Network Address—The Network Address is an identifier used to allow a group of radios
to communicate and exclude nonmember radios. In this example 555 is used.
Device ID—A unique number that identifies a radio on the RF network. Each radio on a
network, as defined by the network address, is required to have a unique ID in a similar
way to IP addresses on an Ethernet network.
Upstream Device ID—For both PTP and PTMP networks, the Upstream Device ID on
the slave radio should be the device ID of the Master Radio that the slave is required to
communicate with. The Upstream Device ID is non-applicable on a master radio and can
be set to the Master’s Device ID.
Downstream Device ID—For PTP networks only, and is configured for the Device ID
of the slave radio that the master is required to communicate with.
Network Radius—For PTP and PTMP networks only. The link distance or maximum
distance of the longest link in the network.
Master Repeat—Bcast: This is the number of times the radio will retransmit a packet.
It is recommended that this setting is 0 for AODV mesh networks. Addr: This specifies
the number of Link-level retries this radio should send when a positive acknowledgement
has not been received for a packet. Setting this parameter too low will cause packets
to be dropped unnecessarily in the presence of temporary interference or other errors.
Setting this parameter too high can cause flooding of retries on the radio mesh when
none will succeed.
Max Payload Bytes—For PTP and PTMP networks.
Dynamic Payload—For PTP and PTMP networks. This setting is off for AODV mesh
networks.
Beacon Rate—For PTP and PTMP networks. This is the number of transmission slots
the master radio may skip if it has nothing to transmit/acknowledge.
Transmit Prob—Upon transmit, the RF module uses a probability-based contention-
management algorithm when the radio is configured for CSMA Peer to Peer mode. Enter
the probability in percent. 25 is the default setting.

Diagnostics
Figure 17. The Radio Diagnostics screen.
SpeedNet SDR Radios continuously monitor several important RF and radio-operating
parameters for each frequency channel they use. These parameters are reported on this
page. Most of the values are self-explanatory, but clarification is provided for the following:
Tx Rate and Rx Rate—These values report a very short running average and can
effectively be considered instantaneous values. As a result, these numbers will
generally be less than the maximum over-the-air data rate unless the measurements
are taken during a sustained transmission.
Input Voltage—This reports the voltage in millivolts supplied by the radio to the
RF Module, and not the voltage supplied to the radio through its external power
connector.
Fwd Power—This is the radio’s output power measured during transmission in
milliwatts.
Reverse Power—This is the power reflected back into the radio during transmis-
sion in milliwatts. High values for Reverse Power are indicative of problems with
RF cabling and/or the antenna.
%Occupancy—This indicates the percentage of time the radio transmitted on the
specified frequency, and the noise measured was below the noise threshold specified
on the RF Transmission Settings screen.
Radio Diagnostics The Diagnostic section has several tabs that provide statistical information regarding Radio
Diagnostics, Channel Utilization, Neighbor List, and Radio RF Ping. See Figure 17.
