Because of the nature of wireless communication, transmission and reception of data can never be guaranteed. Data may
be delayed, corrupted (i.e., have errors), or be totally lost. Significant delays or losses of data are rare when wireless devices
such as the Viper SC are used in a normal manner with a well-constructed network. Viper SC should not be used in
situations where failure to transmit or receive data could result in damage of any kind to the user or any other party,
including but not limited to personal injury, death, or loss of property. CalAmp accepts no responsibility for damages of any
kind resulting from delays or errors in data transmitted or received using Viper SC, or for the failure of Viper SC to transmit
or receive such data.

RF Exposure Compliance Requirements

It is the responsibility of the user to guarantee compliance with the FCC MPE regulations when operating this device in a way
other than described above. The installer of this equipment must ensure the antenna is located or pointed such that it does
not emit an RF field in excess of Health Canada limits for the general population.

Viper SC uses a low power radio frequency transmitter. The concentrated energy from an antenna may pose a health
hazard. People should not be in front of the antenna when the transmitter is operating.

Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are contained in the
Canadian Safety Code 6 (available from Health Canada), the Federal Communications Commission (FCC) Bulletin 65 and the
Council of the European Union’s Recommendation of 12 July 1999 on the limitation of exposure of the general public to
electromagnetic fields (0 Hz to 300 GHz) (1999/519/EC).

Class A Digital Device Compliance

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.

Any changes or modifications not expressly approved by the party responsible for compliance (in the country where used)
could void the user's authority to operate the equipment.

The SETUP and COM serial connections are DE-9F RS-232 ports. Refer to Table 3 for pin out descriptions and Section 4.3.4
for control line configuration of DCD, DTR, RTS and CTS control lines.

Serial port considerations:

 Viper SETUP and COM ports are Data Communication Equipment (DCE) devices
 In general, equipment connected to the Viper SC’s serial ports is Data Terminal Equipment (DTE) and a straight-

through cable is recommended.

 If a DCE device is connected to the Viper serial ports, a null modem cable/adapter is required.

The White Enable line must be tied to the red positive lead of the connector for the Viper SC to function.

1.3.3.4 ANTENNA CONNECTOR

Standard Viper models have a 50-ohm TNC female antenna connector. This connection functions for both transmit and
receive. Dual-Port models feature a 50-ohm TNC female antenna connector functioning for transmit (only) and a 50-ohm
SMA female antenna connector functioning for receive (only). The separate receive antenna connector is ideal for
applications that require additional receive filtering, external PA(s) and other options.

Warning: The transmit antenna port must not be connected directly to the receive antenna port of the Dual-Port Viper SC.
Excessive power into the receive antenna port will damage the radio. Input power to the receiver should not exceed 17 dBm
(50mW).

To reduce potential interference, the antenna type and its gain should be chosen to ensure the effective isotropic radiated
power (EIRP) is not more than required for successful communication.

The antenna connector is for connection to antennas housed inside of a suitable enclosure.

1.4 PRODUCT WARRANTY

It is our guarantee that every Viper SC Radio modem will be free from physical defects in material and workmanship for

2 NETWORK ARCHITECTURE AND SYSTEM PLANNING

This section discusses network architecture, basic network types, interfacing modems and DTE, data protocols for efficient
channel operation, as well as providing tips for selecting an appropriate site, antenna selection, and reducing the chance of
harmful interference.

2.1 NETWORK ARCHITECTURE

In a radio system, only one radio should transmit at a time. If two radios transmit at the same time to another radio, RF
collisions occur. Collisions will slow data traffic and may corrupt data. Most SCADA networks have a device that is
configured to be the ‘polling master’. It is the responsibility of this polling master to control RF traffic so RF collisions do not
occur.

Viper has RF collision avoidance technology (checks the air wave for a carrier before transmitting) and Ethernet CSMA
(Carrier Sense Multiple Access). CSMA is an Ethernet collision avoidance mechanism technology built into to all Ethernet
connections. However, these technologies must still be supplemented by the HMI/PLC polling master to optimize RF data
traffic.

Some HMI/PLC Ethernet applications may depend solely on Ethernet CSMA to control the flow of messages to avoid RF
collisions in a Viper data network. This may flood the network with multiple polling messages, making it difficult for the
RTUs to acquire the airwave to transmit their reply messages. This will cause the RTUs to compete for airtime and a
dominant RTU may be created.

While the dominant RTU/radio is transmitting, the other RTUs will send their reply messages to their connected Viper SC.
Viper SCs will buffer reply messages because the dominant RTU/radio is transmitting (carrier is present). A Viper SC will
buffer (while a carrier is present) a reply message until it can capture the airwave (carrier absent) to transmit. There could
be five or six RTU/radios in a small system (or 10 or 20 in a large system), which could be trying to capture the airwaves to
transmit. The RTUs will not respond in the order they were polled but will respond when they are ready and have captured
the airwaves. The dominant RTU is created because it happens to reply at just the right time and be in the right order in the
polling sequence.

A common method for a polling master to manage RF traffic is for the HMI/PLC polling master to poll one remote at a time.

The next polling message is not sent until the current message has been completed (“Done”) or has timed out. This

prevents more than one outstanding polling message. Ladder logic programs typically refer to these parameters as the

message “Done” and “Error” bits. The “Done” and “Error” bits parameter values can be adjusted for longer timeout values,

if required.

Because the Viper SC has the ability to use two completely different and separate SCADA polling protocols, it is important to
have interaction between the two protocols. The Viper SC can send out an Ethernet TCP/IP polling message and also an
RS232 polling message, which may or may not be generated by the same HMI/PLC. CalAmp recommends the user program

the polling sequence in each protocol with logic that interacts with the other’s protocol “Done” and “Error” bits. The
Ethernet polling protocol would not be allowed to send a message until the current Ethernet message is either “Done” or
“Error” and the previous RS232 message are either “Done” or “Error” bits are set. The RS232 polling protocol would also

have a similar logic.

2.1.1 POINT-TO-POINT

A point-to-point network is the most simple of all networks, and may be used for connecting a pair of PC's, a host computer
and a terminal, a SCADA polling master and one remote, or a wide variety of other networking applications.

Figure 3 – Point to Point Network

2.1.2 POINT-TO-MULTIPOINT

A Point-to-Multipoint network is a common network type used in SCADA and other polling systems. The Master Polling
station communicates with any number of remotes and controls the network by issuing polls and waiting for remote
responses. Individual PLC/RTU remotes manage addressing and respond when their individual addresses are queried.
PLC/RTU unit addresses are maintained in a scanning list stored in the host program or master terminal device at the SCADA
host site. Communications equipment is transparent and does not interact with specific remotes; all data is coupled to the
host on a single data line (such a network is commonly used with synchronous radio modems and asynchronous radio
modems).

Figure 4 – Point to Multipoint Network

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 10

2.1.3 REPORT BY EXCEPTION

In a true Report by Exception configuration, the remotes send data to the master only when an event or exception has
occurred in the remote. However, most Report by Exception systems have a master/remote polling component. The master
polls the remotes once every hour or half-hour to ensure there is still a valid communication path. In a Report by Exception
configuration, there will not be a master controlling RF traffic and RF collisions will often occur.

Viper has several collision avoidance features to help minimize collisions. Viper is a “polite radio”. This means Viper will
check the RF traffic on the receive channel before transmitting. If there is no RF traffic present (no carrier present) it will
transmit. If there is RF traffic (carrier present) the Viper SC will buffer the data. Viper will transmit the buffered data when
there is no RF traffic present.

2.1.4 EXTENDING THE COVERAGE AREA WITH A RELAY POINT

A Viper can be configured as a Relay Point. Relay Points provide store and forward repeating of necessary information from
one coverage area to the next. In Bridge mode all traffic is forwarded. In Router mode, only Broadcast Packets and address
specific packets are forwarded. There may be multiple Relay Points to extend coverage over several hops. Multiple relay
points in a single network may slow the flow of data traffic.

To configure your Viper as a Relay point, refer to Section 3.5.2.

Figure 5 – Two Coverage Areas

2.2 IP FORWARDING MODES

All Ethernet capable devices, or hosts, have at least one IP address and a subnet mask assigned to it. The IP address
identifies a specific device and the subnet mask tells the device which other IP addresses it can directly communicate with.
When any host needs to communicate with another device that is not within the same local area network it will first send
the data packet to the gateway or router. The gateway or router will forward the packet to the desired location. Often
times a packet will pass through several gateways or routers to get to its final destination.

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 11

2.2.1 BRIDGE MODE

Bridge mode is the simplest configuration for all Viper networks. Viper may be configured for bridge mode only when all
devices are located on the same Local Area Network (LAN). Thus, all units in the network can communicate directly with all
other units in the network.

Each Viper has only one IP address assigned to it and the subnet mask is the same for every Viper in the network. Bridge
communications does not require each Viper to have a unique IP address, but it is highly recommended and necessary for
remote programming of the radio.

Every Viper ships from the factory with the default Ethernet IP address of 192.168.205.1 and a subnet mask of

255.255.255.0. The default subnet of the Viper consists of addresses from 192.168.205.0 to 192.168.205.255. The first and
last IP address of each subnet is reserved, no matter what the subnet size is. The first IP address in the subnet is the
Network ID. The last IP address in the subnet is the Broadcast Address.

Bridge Mode Example 1

Example one illustrates a sample Viper network. The subnet consists of IP addresses ranging from 192.168.205.0 to

192.168.205.255. The subnet mask is 255.255.255.0. This is sometimes written in shorthand notation as: 192.168.205.1/24
since the subnet mask 255.255.255.0 contains 24 ones then 8 zeros when it is converted to binary.

The first address 192.168.205.0 is reserved for the Network ID. The last address 192.168.205.255 is reserved for the
broadcast address. There are 254 valid IP addresses that may be assigned to hosts on the network.

Bridge Mode Example 2

The subnet for this Viper network is comprised of devices with IP addresses ranging from 172.20.0.0 to 172.20.255.255. The
subnet mask is 255.255.0.0. The shorthand notation is: 172.20.0.1/16 since the subnet mask 255.255.0.0 contains 16 ones
then 16 zeros when it is converted to binary.

The first address 172.20.0.0 is reserved for the Network ID. The last address 172.20.255.255 is reserved for the broadcast
address. There are 65534 valid IP addresses available to be assigned to hosts on the network.

2.2.2 ROUTER MODE

Router mode allows greater network configuration flexibility, allows the use of a variety of protocols, and also adds RF
diagnostics capability to Viper networks. Diagnostics can be retrieved through the Ethernet port of the Viper. For more
information on Viper RF Diagnostics, refer to Section 4.1.2

Router mode requires the setup of Ethernet IP and Serial IP addresses and is recommended only for users who have
IT/Network support readily available to them and/or the authorization required to make changes in to the network.

In Router mode, each Viper uses two IP addresses:

The Ethernet IP Address
The RF IP Address

Every Viper is factory configured with a default Ethernet IP Address 192.168.205.1 and a unique RF IP address. This RF IP

address will have the form 10.x.y.z where x, y, and z is based on the last 6 digits of the unit’s Ethernet MAC address. The

default network is 10.0.0.0/8.

In Router mode, each Viper must have its Ethernet IP Address on a unique network and all Vipers must have their RF IP
addresses on the same network. For consistent and reliable communication, the RF network addresses should not overlap

or contain any of the IP Addresses in the Ethernet network.

Router Mode Example 1

In this example, each Viper has an Ethernet IP address on a unique network. For Vipers #1, #2, and #3, each network
connected to their local Ethernet ports has 254 valid IP addresses that may be assigned to other hosts. The network

connected to Viper #4’s local Ethernet port has 65534 valid IP addresses.

Note 1: All Vipers’ RF IP addresses are on the same network. Because they are using the 10.0.0.0/8 network, all Vipers may

use the default RF IP address programmed by the factory.

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 14

Note 2: All the Viper Ethernet IP addresses are on different networks.

Note 3: Computers, PLCs, RTUs, or other Ethernet capable devices can be connected up to each Viper’s local Ethernet

interface. That device must be set with an IP address on the same network as the Ethernet interface of the Viper it is
connected with.

Ethernet Subnet Mask: Varies from Viper to Viper.
RF Subnet Mask for all units: 255.0.0.0

Viper 1: Ethernet IP Address: 192.168.205.1/24 RF IP Address: 10.11.12.25/8

PLC 1: 192.168.205.2/24
Computer/HMI 1: 192.168.205.3/24

Viper 2: Ethernet IP Address: 192.168.206.1/24 RF IP Address: 10.9.7.251 / 8

PLC #2: 192.168.206.2 / 24

Viper #3 Eth IP Address: 192.168.207.1/24 RF IP Address: 10.8.0.52 / 8
PLC #3: 192.168.207.2/24
Computer #3: 192.168.207.3/24

Viper #4 Eth IP Address: 172.21.51.105/16

RF IP Address: 10.0.1.11/8

PLC #4: 172.21.51.106/16

Figure 8 – Router Mode Example 1

Router Mode Example 2:

Each Viper has an Ethernet IP address on a unique network.

In this example, each network connected to the Viper’s local Ethernet port has 14 valid IP addresses that may used for the

Viper, PLCs, RTUs, computers, or other Ethernet equipment that may be connected.

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 15

The subnet mask of the RF IP addresses has been changed to ensure that the RF IP network does not overlap any of the
Ethernet networks. In this scenario, the RF IP addresses must be manually programmed to ensure that every Viper has an
RF IP address in the network and that no RF IP address is used twice.

Figure 9 – Router Mode Example 2

2.2.3 MULTISPEED NETWORKING

When using Viper SC with a Viper SC 19” rack mount base station, the user can configure the network for multispeed
operation. With the Base enabled as a ‘rate-controller’, the remote device becomes a ‘rate follower’. The rate-controller
can be configured to talk at different over-the-air data rates for each remote Viper. This allows the user to uniquely control
the data rate for each RF link in the system from the Base Station web pages. The user can program RF links with strong
signal strength to communicate at fast data rates and RF links with low signal strength can be programmed to communicate
at more robust, slower data rates. Even if data rates vary from Viper to Viper, every Viper in the network must be
programmed with the same bandwidth.

Refer to Section 4.3.1 for multispeed configuration options.

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 16

Figure 10 – Multispeed Illustration

2.3 SYSTEM PLANNING

A Site Survey is a propagation study of the RF path between two points or between one point and multiple points. Signal
propagation may be affected by attenuation from obstructions such as terrain, foliage, or buildings in the transmission
path. A Site Survey is recommended for most projects to determine the optimal RF paths for each link. This is especially true
when more than one RF coverage area is required. A Site Survey will determine the best unit location for the Relay Points.

For a successful installation, careful thought must be given to selecting the site for each radio. Suitable sites should provide
the following:

Protection from direct weather exposure
A source of adequate and stable primary power
Suitable entrances for antenna, interface, or other cabling
Antenna location with an unobstructed transmission path to all remote radios in the system

2.3.1 UNDERSTANDING RF PAT H REQUIREMENTS

Radio waves are propagated when electrical energy produced by a radio transmitter is converted into magnetic energy by
an antenna. Magnetic waves travel through space. The receiving antenna intercepts a very small amount of this magnetic
energy and converts it back into electrical energy that is amplified by the radio receiver. The energy received by the
receiver is called the Received Signal Strength Indication (RSSI) and is measured in dBm.

#9 Viper_SC_Manual_001-5008-000_Rev12e.docx | Page 17

A radio modem requires a minimum amount of received RF signal to operate reliably and provide adequate data
throughput. This is the radio’s receiver sensitivity. In most cases, spectrum regulators will define or limit the amount of
signal that can be transmitted and it will be noted on the FCC license. This is the effective isotropic radiated power (EIRP).
Transmitted power decays with distance and other factors as it moves away from the transmitting antenna.

2.3.2 TERRAIN AND SIGNAL S TRENGTH

A line of sight path between stations is highly desirable and provides the most reliable communications link in all cases. A
line of sight path can often be achieved by mounting each station antenna on a tower or other elevated structure that
raises it high enough to clear surrounding terrain and other obstructions.

The requirement for a clear transmission path depends on the distance to be covered by the system. If the system is to
cover a limited distance, then some obstructions in the transmission path may be tolerable. For longer-range systems, any
obstruction could compromise the performance of the system, or block transmission entirely.

The signal strength (RSSI) at the receiver must exceed the receiver sensitivity by an amount known as the fade margin to
provide reliable operation under various conditions. Fade margin (expressed in dB) is the maximum tolerable reduction in
received signal strength, which still provides an acceptable signal quality. This compensates for reduced signal strength due
to multi-path, slight antenna movement or changing atmospheric conditions. CalAmp recommends a 20 dB fade margin for
most projects.

2.3.3 RADIO INTERFERENCE

Interference is possible in any radio system. However, since the Viper is designed for use in a licensed system, interference
is less likely because geographic location and existing operating frequencies are normally taken into account when
allocating frequencies.

The risk of interference can be further reduced through prudent system design and configuration. Allow adequate
separation between frequencies and radio systems. Keep the following points in mind when setting up your radio system.

1) Systems installed in lightly populated areas are least likely to encounter interference, while those in urban and
suburban areas are more likely to be affected by other devices.

2) Directional antennas should be used at the remote end of the link. They confine the transmission and reception
pattern to a comparatively narrow beam, which minimizes interference to and from stations located outside the
pattern.

3) If interference is suspected from another system, it may be helpful to use antenna polarization opposite to the

interfering system’s antennas. An additional 20 dB (or more) of attenuation to interference can be achieved by

using opposite antenna polarization.

4) Check with your CalAmp sales representative or CalAmp Technical Services for additional options. The Technical
Services group has qualified personnel to help resolve your RF issues.

2.3.4 SELECTING ANTENNA AND FEEDLINE

Viper can be used with a variety of antenna types. Viper has been tested and approved with antennas having a maximum
gain of 10 dBi. Refer to Section 1.5 for a list of tested antenna recommendations. These antennas are FCC approved for use
with Viper. Similar antenna types from other manufacturers are equally acceptable. It is important to follow the
manufacturer’s recommended installation procedures and instructions when mounting any antenna.

― Omni Directional Antenna. In general, an Omni directional antenna should be used at a master station and Relay

Points. This allows equal coverage to all of the remote locations. Omni directional antennas are designed to radiate the
RF signal in a 360-degree pattern around the antenna. Short range antennas such as folded dipoles and ground
independent whips are used to radiate the signal in a ball shaped pattern while high gain Omni antennas, such as a
collinear antenna, compress the RF radiation sphere into the horizontal plane to provide a relatively flat disc shaped
pattern that travels further because more of the energy is radiated in the horizontal plane.

― Yagi Antenna. At remote locations (not used as a Relay Point), a directional Yagi is generally recommended to minimize

interference to and from other users.

― Vertical Dipoles. Vertical dipoles are very often mounted in pairs, or sometimes groups of 3 or 4, to achieve even

coverage and to increase gain. The vertical collinear antenna usually consists of several elements stacked one above
the other to achieve similar results.

2.3.4.1 ANTENNA GAIN

Antenna gain is usually measured in comparison to a dipole. A dipole acts much like the filament of a flashlight bulb: it
radiates energy in almost all directions. One bulb like this would provide very dim room lighting. Add a reflector capable of
concentrating all the energy into a narrow angle of radiation and you have a flashlight. Within that bright spot on the wall,
the light might be a thousand times greater than it would be without the reflector. The resulting bulb-reflector combination
has a gain of 1000, or 30 dB, compared to the bulb alone. Gain can be achieved by concentrating the energy both vertically
and horizontally, as in the case of the flashlight and Yagi antenna. Gain can be also be achieved by reducing the vertical
angle of radiation, leaving the horizontal alone. In this case, the antenna will radiate equally in all horizontal directions, but
will take energy that otherwise would have gone skywards and use it to increase the horizontal radiation.

The required antenna impedance is 50 ohms. To reduce potential radio interference, the antenna type and its gain should
be chosen to ensure the effective isotropic radiated power (EIRP) is not more than required for successful communication.

2.3.4.2 FEEDLINE

The choice of feedline should be carefully considered. Poor quality coaxial cables should be avoided, as they will degrade
system performance for both transmission and reception. The cable should be kept as short as possible to minimize signal
loss. See Table 8 for feedline recommendations.

Table 8 – Transmission Loss (per 100 Feet)

Outside cable connections should have a weather kit applied to each connection to prevent moisture. Feedline connections
should be routinely inspected to minimize signal loss through the connection. A 3 dB loss in signal strength due to cable loss
and/or bad connections represents a 50% reduction in signal strength.

An RX/TX antenna is required for basic operation. For demo units only, connect the
antenna as shown to provide stable radio communications between demo devices.

It is important to use attenuation between all demo units in the test network to reduce the
amount of signal strength in the test environment.

3 QUICKSTART

It is easy to set up a Viper network to verify basic operation and to experiment with network designs and configurations. To
eliminate unnecessary disruption of traffic on the existing network while you become familiar with Viper, you should use a
network IP subnet address different from others currently in use in your test area.

3.1 PC LAN SETUP

On a PC running MS-Windows with an existing LAN connection, connect to the Ethernet input of the Viper SC and complete
the following steps.

3.2 INSTALL THE ANTENNA

3.3 MEASURE AND CONNECT PRIMARY POWER

Primary power for Viper must be within 10-30 VDC and be capable of providing a minimum of:

 10 watt supply for Tx @ 1W
 40 watt supply for Tx @ 5W, or
 60 watt supply for Tx @ 10 W

Viper Demo Kits contain a power connector with screw-terminals. Observe proper polarity when connecting the cables to
the Power Supply. The white wire must be connected to red wire.

3.4 CONNECT VIPER SC TO PROGRAMMING PC

Connect a PC’s Ethernet port to the LAN port using a CAT 5 Ethernet cable. Wait for the LINK LED to glow green.
