RF Exposure

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 Guardian are used in a
normal manner with a well-constructed network. Guardian 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 Guardian, or for the failure of Guardian to transmit or receive
such data.

RF EXPOSURE COMPLIANCE REQUIREMENTS

The Guardian radio is intended for use in the Industrial Monitoring and Control
and SCADA markets. The Guardian unit must be professionally installed and must ensure a
minimum separation distance listed in the table below between the radiating structure and any
person. An antenna mounted on a pole or tower is the typical installation and in rare instances,
a 1/2-wave whip antenna is used.

Note: 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 Guardian radio 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.

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. Recommended
safety guidelines for the human exposure to radio frequency electromagnetic energy are
contained in the Canadian Safety Code 6 (available from Health Canada) and the Federal
Communications Commission (FCC) Bulletin 65.

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.

1 GUARDIAN OVERVIEW

This document provides information required for the operation and verification of the
CalAmp Guardian Narrowband Modem.

1.1 GENERAL DESCRIPTION

This DSP-based radio was designed for SCADA, telemetry and industrial applications in the
136-174 MHz, 215-240 MHz VHF, 406.1-512 MHz UHF, and 928-960 MHz frequency ranges.

Guardian supports serial Remote Terminal Units (RTU) and programmable logic controllers
(PLC). The Guardian is compatible with any Dataradio Interoperability Standard (DI-OS)
equipment and Bell 202/212 interface.

1.2 OPERATIONAL CHARACTERISTICS

The Guardian product has the following operational characteristics:

 Frequency range of 136-174 MHz, 215-240 MHz, 406.1-470 MHz, 450-512 MHz, or

928-960 MHz.

 User-selectable data rates
 Built-in transceiver adjustable from 1 to 10 watts (8 watts max for 900MHz)
 Wide input power range of 10 to 30 volts DC
 Online and Offline Diagnostics
 Supports up to 8 different frequency channel pairs (selectable through user interface

port).

 Industrial operating temperature range of -30 to +60 C
 Rugged die-cast aluminum and steel case

001-5006-000_FCC.docx Page 9

These features provide system benefits that give users:

Rugged Packaging. Guardian is housed in a compact and rugged cast aluminum case.
Built for industrial applications in a variety of environments, Guardian operates over an
extended temperature range and provides worry-free operation in the roughest
environments.

Simple Installation. Basic installation typically utilizes an omni-directional antenna at the
master station or Relay Point and a directional antenna at each remote site not a Relay
Point. See Section 2 for information on Site and Antenna Selection. For basic service, just
hook up an antenna, apply primary power, check and set a few operating parameters and
you are done.

Flexible Management. Configuration, commissioning, maintenance and troubleshooting
can be done locally or remotely. There are no physical switches or adjustments. The Dual­Port Guardian provides a receive antenna connector allowing for unique customer
applications requiring additional receive filtering, external PA(s), and other options.

Long Range. Narrowband configurations allow better coverage over harsh terrain.

1.3 PHYSICAL DESCRIPTION

Guardian consists of two logic PCBs, one that includes the modem circuitry and the other
the radio module. Both are installed in a cast aluminum case. The unit is not hermetically
sealed and should be mounted in a suitable enclosure when dust, moisture, and/or a
corrosive atmosphere are anticipated.

The Guardian is designed for easy installation and configuration; the Guardian features no
external or internal switches or adjustments. All operating parameters are set via the setup
port.

1.3.4 SETUP and COM Ports

The SETUP and COM serial connections are DE-9F RS-232 ports.
Serial port considerations:

 Guardian radio modem SETUP and COM ports are Data Communication Equipment

(DCE) devices

 In general, equipment connected to the Guardian’s SETUP / COM serial port is Data

Terminal Equipment (DTE) and a straight-through cable is recommended.
Note: If a DCE device is connected to the Guardian SETUP / COM port, a null modem

cable/adapter is required.

The pin-out for the SETUP and COM ports are shown in Table 1.3.

Table 1.3 Pin-out for DCE SETUP and COM port, 9 Contact DE-9 Connector

The DCD, DTR, RTS and CTS control lines are programmable. Refer to section 6.4 for serial
port control line configurations.

1.3.5 Power Connector

The Guardian is supplied with a right-angle power connector (10-30 VDC). Table 1.4 shows
the pin-out of the power connector.

Table 1.4 Pin-out of the power connector

Note: The White Enable line must be tied to the red positive lead of the connector for the
Guardian to function.

001-5006-000_FCC.docx Page 12

1.3.6 Antenna Connector

The standard Guardian has a 50-ohm TNC female antenna connector. This connection
functions for both transmit and receive.

The Dual-Port Guardian has 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 allows for unique customer 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 Guardian. 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.

This section briefly discusses network architecture (including basic network types),
interfacing modems and DTE, data protocols for efficient channel operation, addressing, and
repeaters.

Guardian is designed to replace wire lines in SCADA, telemetry and control applications. The
RS-232 serial port allows direct connection to Programmable Logic Controllers (PLCs) or
Remote Terminal Units (RTUs). A SCADA system is defined as one or more centralized
control sites used to monitor and control remote field devices over wide areas. For
example, a regional utility may monitor and control networks over an entire metropolitan
area. Industry sectors with SCADA systems include energy utilities, water and wastewater
utilities, and environmental groups.

The Guardian is intended for use in the Industrial Monitoring and SCADA market. The range
of the Guardian is dependent on terrain, RF (radio frequency) path obstacles, and antenna
system design. This section provides tips for selecting an appropriate site, choosing an
antenna system, and reducing the chance of harmful interference.

2.1 SINGLE COVERAGE AREA

In a network topology with only a single coverage area (all units can talk to one another
directly), there are several common system configurations.
The most common is for one unit to be designated as a master and the rest designated as
remotes. Another system configuration is Report-by-Exception.

2.2 NETWORK ARCHITECTURE

2.2.1 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,
mobile applications (like in-vehicle GPS receivers and base stations) or a wide variety of
other networking applications.

2.2.2 Point-to-Multipoint

A Point-to-Multipoint network is a common network type used in SCADA or other polling
systems. The single polling master 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 2.2 – Point to Multipoint Network

2.2.3 Multiple Point-to-Point

A multiple point-to-point is similar to the point-to-multipoint system except
the SCADA host has multiple serial ports that are directed to different
geographic areas in the SCADA system.

2.2.4 Peer-to-Peer

A Peer-to-Peer network is generally used for device to device communications
among a number of stations. This network requires full addressing capability
on the part of the data equipment (DTE). If the distances involved for any link
or links are too great for a single radio hop, they can be extended by means
of repeaters without affecting the basic network design.

2.2.5 Store and Forward

Store and Forward is a common technique where a data transmission is sent
from one device to a receiving device but first passes through a relaying
device. The device is typically an RTU or PLC used by the message service to
store the received message then it transmits the message to the intended
recipient.

2.2.6 Network Using a T-Base

The Network Using a T-Base configuration has the following characteristics:
 Master station may be full duplex (duplexer required), half duplex, or simplex
