Description
Installation Choose a location, where the SpeedNet ME Radio can be securely mounted.
CAUTION
For remote antenna installations, where the antenna is not mounted directly on the
control enclosure, S&C recommends installing lightning protection.
Network Design SpeedNet ME Radios serve as a communication end point for SCADA devices. They can
connect to a SpeedNet ME Radio mesh network. They can be installed in a variety of
network congurations. Plan your network in advance, and develop a logical IP address-
ing scheme for your particular application. Depending on your network type, several
factors may inuence your design:
• Point-to-point vs. end-point within a mesh
• Stand-alone Network Connection.
When network topology has been determined, the SpeedNet ME Radios can be cong-
ured appropriately.

6 S&C Instruction Sheet 1074-510
Description
IP Basics SpeedNet ME Radios use Internet Protocol version 4, and all references to IP addresses in
these installation instructions refer to IPv4 addresses. An Internet Protocol (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
internal 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, 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.

S&C Instruction Sheet 1074-510 7
Description
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:
10101100.00011010.11110000.11001000 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 There are three IP network addresses 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, due to 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
ME Radios have unique MAC addresses. Some devices have user-congurable MAC
addresses, but the SpeedNet ME 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 1 on page 8.

Network Example Use of private IP addresses is strongly recommended when conguring a SpeedNet ME
Radio network. The following example of a SpeedNet ME Radio network uses several
private IP subnets from the 192.168.0.0 block of private addresses.
The SpeedNet ME Radio network, depicted in Figure 1, contains three Ethernet
segments. 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.

Description
Once the individual data networks are established, you should plan the IP addressing
scheme. In Figure 1 on page 8, each SpeedNet ME 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 than the subnets used for the Ethernet segments. The wireless interface of the
SpeedNet ME Radio from Subnet 1 is assigned an address of 192.168.203.1. The wireless
interface of the SpeedNet ME Radio from Subnet 2 is assigned an address of 192.168.203.2.
The wireless interface of the SpeedNet ME 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 The SpeedNet ME Mesh End-Point Radio is an end node radio and does not participate in
building the mesh network. It does however, connect to a SpeedNet Radio mesh network
that is capable of providing secure, long range communication with high-message rates.
SpeedNet ME Radios provide a point-to-point wireless connection between two or more
separate Ethernet subnets. Data is then routed between the Ethernet subnets. Route
information can be entered manually, or can be processed automatically by Ad hoc
On-demand Distance Vector (AODV). See Figure 2 on page 9 for an example of a wireless
network using SpeedNet ME Radios with AODV. AODV Routing is a routing protocol for
mobile ad hoc networks and other wireless ad hoc networks. SpeedNet ME Radios use a
proprietary AODV routing system, that works dynamically to maintain message routing. It
generates fewer transmissions, and conserves network capacity. In the case of SpeedNet
ME, AODV will be limited to discovering and establishing the best possible point-to-point
link. SpeedNet ME Radios will not act as message relays for other nodes in the network.
Using Static Routes The routing mode to use (static routes vs. AODV) will be determined by the present
conguration of the network with respect to routing mode (whether it is using static
routes or AODV). The radios do not support a mixture of static routes and AODV routing.
See Figure 3.

S&C Instruction Sheet 1074-510 11
Description
To route traffic between subnets, several things must happen. First, all hosts on a
given subnet must use the attached SpeedNet ME 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. If AODV is disabled, and static routing is
used, it is necessary to add static routes in each SpeedNet ME Radio. The SpeedNet ME
Radio from Subnet 1 must have a static route to Subnet 2, using the SpeedNet ME 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 alterna-
tive, manual routes can be entered in each host’s routing table. The SpeedNet ME Radio
from Subnet 2 must have a static route to Subnet 1, using the SpeedNet ME 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 that 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 should be on the same
subnet, while all radio Ethernet IP addresses should be on different, non-overlapping
subnets.
Regulatory
Information
FCC Warning
This device must be professionally installed. It is the responsibility of the installer to
ensure that proper antenna and cable combinations are used in order to remain within
FCC Part 15 limits.
The SpeedNet ME 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 FCC Part 15 Rules. In August 1996, the FCC adopted RF exposure
guidelines 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 ME Radio complies with these FCC exposure guidelines when the
following precautions are obeyed:
• One of the exact antennas recommended in this instruction sheet is installed.
• The cable run for the selected antenna exceeds the minimum length quoted in this
instruction sheet.
• All persons maintain a minimum separation of 12 inches (30.48 cm) from the Speed-
Net ME antenna.
Disconnect the ac/dc input power source from the SpeedNet ME Radio whenever
repositioning the antenna. You are responsible for taking the necessary steps to ensure
that these guidelines are communicated to all persons that may come near the SpeedNet
ME Radio antenna.

12 S&C Instruction Sheet 1074-510
Description
Antenna
Requirements
SpeedNet ME Radios have been designed to operate with the antennas listed below,
having a maximum gain of 3 dBd (5.15 dBi) or 10 dBd (12.15 dBi), respectively, and an
impedance of 50 ohms:
• Omni-directional berglass antenna: Antenex FG9023 or equivalent,
3 dBd (5.15 dBi)
• Uni-directional Yagi antenna: Kathrein TY-900 or equivalent,
10 dBd (12.15 dBi)
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not more
than permitted for successful communication.
Antenna/Cable
Requirements
Antennas for SpeedNet ME Radios must be installed by a qualied radio technician, in
order to comply with FCC Part 15 radiated power limits. Only antennas supplied by S&C
Electric Company may be used with the SpeedNet ME Radio.
The FCC mandates that Effective Isotropic Radiated Power (EIRP) may not exceed
+36 dBm. This is equivalent to a radio running at full output power (1 watt +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 com-
pliance. SpeedNet ME Radios have configurable transmit power which can be selected
using the SpeedNet ME Radio client tool or by using IntelliTeam CNMS. Settings of
+30 dBm (default), +25 dBm, and +10 dBm are available. Any confirmed decrease
in output power should be considered when calculating ERIP.
Tables 2 and 3 show the amount of loss incurred with several common antenna cables.
