Installation
Before
Starting
Choose a location where the SpeedNet ME radio can be securely mounted.
NOTICE
For remote antenna installations, where the antenna is not mounted directly on the control
enclosure, S&C recommends installing lightning protection to avoid damaging the SpeedNet
ME radio.
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 addressing 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 configured
appropriately.

S&C Instruction Sheet 1074-510 5
Operation
IP Basics
SpeedNet ME radios use Internet Protocol (IP) version 4, and
all references to IP addresses in these installation instruc-
tions 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. The IP address class
can be determined 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 deci-
mal.
• Class D addresses begin with 1110, or 224 to 239 deci-
mal.
• Class E addresses begin with 1111, or 240 to 254 deci-
mal.
Addresses beginning with 01111111, or 127 decimal,
are reserved for loop-back and internal testing on a
local machine. This can be tested by pinging 127.0.0.1,
which points to the 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 two
octets (x.x.220.200).
To specify the network address in an IP address, the
node section is entered as zeros. In the 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 sent to
all nodes on the network and is indicated as 172.26.255.255,
which is the broadcast address for the example. Note that
this is true for all classes, regardless of the length of the
node section.

6 S&C Instruction Sheet 1074-510
Operation
Subnet Masking
Applying a subnet mask to an IP address allows the
network and node parts of the address to be identied.
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 the 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
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 organization, 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 retransmis-
sions. 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 identifier 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 they be unique.
Unlike IP addresses, MAC addresses do not have node
and network sections, and a receiving node cannot deter-
mine any network information from the MAC address. The
length of a MAC address is six bytes, and an IP address
is four 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 speci-
fied 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 7.

Network Example
S&C strongly recommends use of private IP addresses
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.

Operation
When the individual data networks are established,
the IP addressing scheme should be planned. In
Figure 1 on page 7. 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 inter-
face 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.
It would be helpful to draw a diagram as a planning aid
and reference guide when designing the 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 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
are then routed between the Ethernet subnets. Route
information can be entered manually, or it can be pro-
cessed automatically by Ad hoc On-demand Distance
Vector (AODV). See Figure 2 on page 8 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 gener-
ates fewer transmissions and conserves network capacity.
In the case of SpeedNet ME radios, AODV will be limited
to discovering and establishing the best possible point-to-
point link. SpeedNet ME radios will not serve 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 roting 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.

10 S&C Instruction Sheet 1074-510
Operation
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 alternative, 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 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. Otherwise, the radios will
not be able to communicate with each other.
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 transceiv-
ers. 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 instruc-
tion 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 SpeedNet ME radio 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 these guidelines are communicated to all persons
that may come near the SpeedNet ME radio antenna.

S&C Instruction Sheet 1074-510 11
Operation
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 chosen so 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 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 equiva-
lent 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 to bring the EIRP
into compliance. SpeedNet ME radios have configurable
transmit power that can be selected using the SpeedNet
ME radio client tool or by using the IntelliTeam® CNMS
Communication Network Management System. Settings of
+30dBm (default), +25 dBm, and +10 dBm are available.
Any confirmed decrease in output power should be con-
sidered when calculating ERIP.
Tables 2 and 3, and Tables 4 and 5 on page 12 show the
amount of loss incurred with several common antenna
cables.
