Regulatory
Information
The SpeedNet SDR Software Dened Radio uses a licensed band, and no one is permitted to
use this band without an appropriate license. This device must be professionally installed.
It is the responsibility of the installer to ensure proper antenna and cable combinations are
used to remain within the license limits.
The SpeedNet SDR Radio is specifically designed to close the longest possible links. This
goal is accomplished in part by delivering the highest permissible RF output power to the
antenna per the limits of the license. In August 1996, the FCC adopted RF exposure guide-
lines that established safety levels for various categories of wireless transceivers. Those
limits are consistent with safety standards previously published by the National Council on
Radiation Protection (NCRP) Report 86, §17.4.1, §17.4.1.1, §17.4.2, and §17.4.3 as well as the
American National Standards Institute (ANSI) in §4.1 of “IEEE Standard for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 30
GHz,” ANSI/IEEE C95.1-1992.
The SpeedNet SDR–4 Radio and SpeedNet SDR–4×4 Radio comply with these FCC expo-
sure guidelines when the following precautions are obeyed:
• The radios have a maximum transmitted output power of 2000 mW in 450- to 470-MHz
band. With maximum settings (2 W), these models require that the transmit antenna be
kept at least 3.9 meters away from nearby persons when connected to an 6-dBd antenna.
Introduction

S&C Instruction Sheet 1075-510 3
Introduction
The SpeedNet SDR 9 Radio and SpeedNet SDR 9×9 Radio comply with these FCC expo-
sure guidelines when the following precautions are obeyed:
• Have a maximum transmitted output power of 3000 mW in 928- to 960-MHz band. With
maximum settings (3 W), these models require that the transmit antenna be kept at least
65.56 cm away from nearby persons.
Disconnect the ac/dc input power source from the SpeedNet SDR Radio whenever repo-
sitioning the antenna. You are responsible for taking the necessary steps to ensure these
guidelines are communicated to all persons that may come near the SpeedNet SDR Radio
antenna.

Antenna/Cable
Installation
Requirements
NOTICE
Antennas for SpeedNet SDR Radios must be installed by a qualified radio technician
to comply within the radiated power limits of the license. Only antennas supplied by
S&C Electric Company may be used with the SpeedNet SDR Radios.
For the following example, assume the license allows for a maximum of 1 W (+30dBm)
radiated power and 4 W (+36dBm) Effective Isotropic Radiated Power (EIRP). This is
equivalent to a radio running at output power (1 W +30 dBm) with a +6 dBi antenna. The
antenna cable must have sufficient loss to bring the EIRP below +36 dBm if a higher-
gain antenna is used. For example, using a +8 dBi antenna with a radio transmitting
at full power would result in an EIRP of +38 dBm. In this situation, the antenna cable
must provide at least 2-dB loss in order to bring the EIRP into compliance. SpeedNet
SDR Radios have configurable transmit power that can be selected using the SpeedNet
SDR Web server, command line interface, or by using IntelliTeam® CNMS Communica-
tion Network Management System. Any confirmed decrease in output power should be
considered when calculating EI R P.
Tables 1 through 4 show the amount of loss incurred with several common antenna cables.

IP Basics SpeedNet SDR Radios use IP version 4, and all references to IP addresses in these installation
instructions refer to IPv4 addresses. An IP address is the unique identier for a node (host
connection) on an IP network. The IP address is a 32-bit binary number, usually shown as
four decimal values separated by decimal points. Each value represents 8 bits in the range
0 to 255 (known as octets), and this is called “dotted decimal” notation.
For example: 172.26.220.200 can be viewed in binary form:
172.26.220.200
10 1 0 11 00.000 11 0 1 0.11 0 11100.11 00 1 000
Every IP address consists of two parts that identify the network and the node. The
address class and subnet mask determine which part belongs to the network address and
which part belongs to the node address.
There are five address classes. You can determine the IP address class by examining
the first four bits of the IP address.
• Class A addresses begin with 0xxx, or 1 to 126 decimal.
• Class B addresses begin with 10xx, or 128 to 191 decimal.
• Class C addresses begin with 110x, or 192 to 223 decimal.
• Class D addresses begin with 1110, or 224 to 239 decimal.
• Class E addresses begin with 1111, or 240 to 254 decimal.
Addresses beginning with 01111111, or 127 decimal, are reserved for loop-back and inter-
nal testing on a local machine. You can test this by pinging 127.0.0.1, which points to your
local machine. Class D addresses are reserved for multicasting, and Class E addresses are
reserved for future use and should not be used for a host address.
This is how the class determines, by default, which part of the IP address belongs to the
network (N) and which part belongs to the node (n).
• Class A–NNNNNNNN.nnnnnnnn.nnnnnnnn.nnnnnnnn
• Class B–NNNNNNNN.NNNNNNNN.nnnnnnnn.nnnnnnnn
• Class C–NNNNNNNN.NNNNNNNN.NNNNNNNN.nnnnnnnn
In the example above, 172.26.220.200 is a Class B address, so by default the network part
of the address (known as the network address) is defined by the first two octets (172.26.
x.x) and the node part is defined by the last 2 octets (x.x.220.200).
To specify the network address in an IP address, the node section is entered as zeros.
In our example, 172.26.0.0 specifies the network address for 172.26.220.200. When the node
section is set to all “1”s, it specifies a broadcast that is sent to all nodes on the network and
is indicated: 172.26.255.255, which is the broadcast address for our example. Note that this
is true for all classes, regardless of the length of the node section.
Installation

10 S&C Instruction Sheet 1075-510
Subnet Masking Applying a subnet mask to an IP address allows you to identify the network and node parts
of the address. The network bits are represented by the “1”s in the mask, and the node
bits are represented by the “0”s. Performing a bitwise logical AND operation between the
IP address and the subnet mask results in the network address or number. The network
address is also called the subnet.
For example, using our test IP address and the default Class B subnet mask, we get: 101
01100.00011010.11110000.11001000 172.26.240.200 Class B IP address
11111111.11111111.00000000.00000000 255.255.000.000 Default Class B subnet mask
10101100.00011010.00000000.00000000 172.26.000.000 network address
Default subnet masks:
• Class A–255.0.0.0–11111111.00000000.00000000.00000000
• Class B–255.255.0.0 –11111111.11111111.00000000.00000000
• Class C–255.255.255.0–11111111.11111111.11111111.00000000
Private Subnets Three IP network addresses are reserved for private networks. The addresses are 10.0.0.0,
Subnet Mask 255.0.0.0; 172.16.0.0, Subnet Mask 255.240.0.0; and 192.168.0.0, Subnet Mask
255.255.0.0. These addresses are also notated 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
They can be used by anyone setting up internal IP networks, such as a lab or home LAN
behind a NAT or proxy server or a router. It is always safe to use these because routers on
the Internet by default will never forward packets coming from these addresses.
Subnetting an IP network can be done for a variety of reasons, including organiza- tion,
use of different physical media (such as Ethernet, FDDI, WAN, etc.), preservation of address
space, and security. The most common reason is to control network traffic. In a traditional
unswitched Ethernet network, all nodes on a segment see all the packets transmitted by all
the other nodes on that segment. Performance can be adversely affected under heavy traffic
loads because of collisions and the resulting retransmissions. A router is used to connect
IP networks to minimize the amount of traffic each segment must receive.
MAC Address In networking, the Media Access Control (MAC) address is a unique identier programmed
into each network device. This number acts like a name for the device, and all SpeedNet SDR
Radios have unique MAC addresses. Some devices have user-congurable MAC addresses,
but the SpeedNet SDR Radio MAC address is congured at the factory and cannot be
changed. Most protocols use MAC addresses that are globally unique, but not all protocols
use MAC addresses or require that they be unique.
Unlike IP addresses, MAC addresses do not have node and network sections, and a
receiving node cannot determine any network information from the MAC address. The
length of a MAC address is 6 bytes, and an IP address is 4 bytes long. Therefore, the MAC
address cannot be represented using an IP address. So an IP address must be mapped to
its corresponding MAC address. Address Resolution Protocol (ARP) is used to locate a
specific MAC address. ARP broadcasts an ARP request packet, which contains the source
MAC address, the source IP address, and the destination IP address. Each node in the local
network receives this packet. A node that has the specified destination IP address returns
an ARP reply packet containing its MAC address to the originating host.
On broadcast networks, such as Ethernet, the MAC address allows each node to be
uniquely identified and allows frames to be marked for specific nodes. It thus forms the
basis of most of the Layer 2 networking upon which higher OSI layer protocols are built to
produce complex functioning networks. See Table 5 on page 11.

Network Example Use of private IP addresses is strongly recommended when conguring a SpeedNet SDR
Radio network. The following example of a SpeedNet SDR Radio network uses several
private IP subnets from the 192.168.0.0 block of private addresses.
The SpeedNet SDR Radio network, depicted in Figure 1, contains three Ethernet seg-
ments. The first segment uses the 192.168.200.0 Class C subnet, encompassing a range of
addresses from 192.168.200.1 to 192.168.200.254. The second segment uses the 192.168.201.0
Class C subnet, encompassing a range of addresses from 192.168.201.1 to 192.168.201.254.
The third segment uses the 192.168.202.0 Class C subnet, encompassing a range of addresses
from 192.168.202.1 to 192.168.202.254. All three radios share the 192.168.203.0 Class C subnet
for their wireless interfaces. It is over this common subnet that traffic is routed between
Ethernet segments.

Radio Network
Figure 1. Multi-network using SpeedNet SDR Software Defined Radios.

12 S&C Instruction Sheet 1075-510
When the individual data networks are established, you should plan the IP addressing
scheme. In Figure 1 on page 7, each SpeedNet SDR Radio host ID is 1 and each automatic
switch control host ID is 2. Following a numbering scheme such as this will make it easier
to keep track of which IP addresses are used for each device.
The SCADA network in this example uses the 192.168.203.0 subnet. This subnet is different
from the subnets used for the Ethernet segments. The wireless interface of the SpeedNet
SDR Radio from Subnet 1 is assigned an address of 192.168.203.1. The wireless interface of
the SpeedNet SDR Radio from Subnet 2 is assigned an address of 192.168.203.2. The wireless
interface of the SpeedNet SDR Radio from Subnet 3 is assigned an address of 192.168.203.3.
You may find it helpful to draw a diagram as a planning aid and reference guide when
designing your SCADA network.
Routing Options As a router, SpeedNet SDR Radios provide a wireless connection between two or more
separate Ethernet subnets. Data are then routed between the Ethernet subnets. Route
information can be entered manually, or it can be processed automatically by AODV. See
Figure 2 on page 13 for an example of a wireless network using SpeedNet SDR Radios with
AODV.
The type of network you are designing will help determine the best routing mode to use.
If the network consists of stationary SpeedNet SDR Radios that are communicating either
point to point or point to multipoint, choose the Off setting for Ad-Hoc Routing mode.
This allows you to insert static routes for each SpeedNet SDR Radio and its connected
network. When route redundancy is not required, the Off setting is likely the best choice
for Ad-Hoc Routing mode. Note that if static routing is selected (ad-hoc routing mode is
off), then all routes that a given radio might need must be specified as static routes. The
radios do not support a mixture of static routes and AODV routing. See Figure 3 on page 14.
When the network consists of meshed SpeedNet SDR Radios, choose AODV, the ad-hoc
routing mode. This mode allows the SpeedNet SDR Radios to automatically find their
neighbors and quickly and dynamically update the route tables as the network topology
changes. For environments where routes are required to change dynamically or where
enhanced reliability through redundancy is required, AODV is typically the best ad-hoc
routing mode to choose.

Using Static Routes Figure 3 is an example of a point-to-point SpeedNet SDR Radio network. In this example,
Subnet 1 has been assigned the 192.168.1.0 Class C subnet, while Subnet 2 has been assigned
the 192.168.2.0 Class C subnet. For the wireless network common between the two radios,
the 192.168.3.0 Class C subnet has been assigned.

Figure 3. Wireless network using SpeedNet SDR Radios with static routes.
To route trafc between subnets, several things must happen. First, all hosts on a given
subnet must use the attached SpeedNet SDR Radio as their default gateway. As an alternative,
manual routes can be entered in each host’s routing table. Hosts from Subnet 1 will list
192.168.1.1 as their default gateway. Assuming that ad-hoc routing is deactivated, it is also
necessary to add static routes in each SpeedNet SDR Radio. The SpeedNet SDR Radio from
Subnet 1 must have a static route to Subnet 2, using the SpeedNet SDR Radio from Subnet
2 as the gateway. The route should be set up like this:
192.168.2.0 255.255.255.0 192.168.3.2
Network Netmask Gateway
All hosts from Subnet 2 should use 192.168.2.1 as their default gateway. As an alternative,
manual routes can be entered in each host’s routing table. The SpeedNet SDR Radio from
Subnet 2 must have a static route to Subnet 1, using the SpeedNet SDR Radio from Subnet
1 as the gateway. This route should be set up like this:
192.168.1.0 255.255.255.0 192.168. 3.1
Network Netmask Gateway
NOTICE
It is important to understand there are actually three subnets in this example:
Subnet 1, Subnet 2, and the radio network.
It is also important that all radio wireless IP addresses be on the same subnet, while
all radio Ethernet IP addresses must be on different, non-overlapping subnets.

The SpeedNet SDR Radio Ethernet interfaces use an RJ-45 connector with the pinout
shown in Table 8. The Ethernet port is on the rear panel of the SpeedNet SDR Radio. It is
auto-sensing for assignment of transmit and receive lines (no crossover cables required) and
auto-negotiates for a 10-Mbps or 100-Mbps data rate as required by the connected device.
