RF EXPOSURE COMPLIANCE REQUIREMENTS
RF E
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.
REGULATORY CERTIFICATIONS
The Guardian radio is available in several different models each with unique frequency bands. Each model of Guardian
may have different regulatory approval as shown in the table below.

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

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 Dual‐Port 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.
1.3.1 FRONT PANEL
The front panel has the following connections:
ƒ
(1) 8‐Pin user interface block connector
ƒ
(1) 50‐ohm TNC female Antenna connector

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.

SYSTEM ARCHITECTURE AND NETWORK PLANNING
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.
Figure 2.1 – Point‐to‐Point Network
Guardian Manual 001‐5006‐000 Rev 0
17 | P a g e
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:
ƒ
Master station may be full duplex (duplexer required), half duplex, or simplex
ƒ
Online diagnostics are available using the Online Diagnostics utility without disrupting network activity
ƒ
Remote / local diagnostics and statistics / control are available using the Guardian Offline Diagnostics utility
when connected to the Tx module (not Diag Port of T‐Base)
ƒ
The T‐Base provides output of Online Diagnostic information which can be processed by the Guardian Online
Diagnostics utility or by a user‐supplied network management program. Contact your sales representative for
further information.
2.2.7 NETWORK USING A T‐BASE REPEATER
The Network Using a T‐Base Repeater has the following characteristics:
ƒ
Master station and all remotes must be half duplex
ƒ
Networks described in Section 1.10.2, 1.10.3, or 1.10.5 may be used with a T‐Base repeater
ƒ
The RTS/CTS delays for each GUARDIAN in the system must be extended as shown in Table 2‐6, RTS/CTS
Delays
2.2.8 NETWORK USING A GUARDIAN FOR ONLINE DIAGNOSTICS
The Network Using a Guardian for Online Diagnostics configuration has the following characteristics:
ƒ
Master station may be half duplex or simplex
ƒ
Accumulated online diagnostics for a maximum of 15 stations are available at a monitoring site (monitoring
site must be in range of all remotes)
ƒ
Online Diagnostics are available in real time at the monitoring site
ƒ
Remote Offline Diagnostics, statistics, and control are available from the monitoring site by temporarily
disabling network activity (best if using a Master Station Antenna System)
Online Diagnostics are accumulated in the monitoring Guardian for the last 15 stations heard. This information
may be viewed using the Online Diagnostics utility. For larger networks, the Guardian can output raw diagnostic
data only which may be interpreted for network management by the Calamp Field Programming Software Online
Diagnostics utility or by a user‐supplied software program. Contact your sales representatives for more
information.

2.3
EXTENDING THE COVERAGE AREA WITH A RELAY POINT
The Guardian has a Relay Point feature that allows a unit to relay data from one RF coverage area to another RF
coverage area. When units are spread over two or more coverage areas, the user must identify the devices forming
the backbone between coverage areas so any unit can talk to any other regardless of their locations. There can be
multiple Relay Points in the system extending the coverage over several hops.
Figure 2.3 ‐ Two Coverage Areas
The unit forming the backbone between the coverage areas must be configured to repeat all necessary
information from one coverage area to the next. This unit must have the Relay Point parameter enabled (See
Section 6.1).
2.3.1 UNDERSTANDING RF PATH 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.
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.
Guardian Manual 001‐5006‐000 Rev 0

2.4
SITE SELECTION AND SITE SURVEY
2.4.1 SITE SELECTION
For a successful installation, careful thought must be given to selecting the site for each radio. Suitable sites should
provide the following:
ƒ
Protection from direct weather exposure
ƒ
A source of adequate and stable primary power
ƒ
Suitable entrances for antenna, interface, or other cabling
ƒ
Antenna location with an unobstructed transmission path to all remote radios in the system
These requirements can be quickly determined in most cases.
2.4.2 SITE SURVEY
A Site Survey is an RF propagation study of the RF path between two points or between one point and multiple
points. UHF radio signals travel primarily by line of sight and obstructions between the sending and receiving
stations will affect system performance. Signal propagation is also 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.
2.5
SELECTING ANTENNA AND FEEDLINE
The Guardian can be used with a variety of antenna types. The exact style used depends on the physical size and
layout of a system. The Guardian device has been tested and approved with antennas having a maximum gain of
10 dBi.
2.5.1 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.
Guardian Manual 001‐5006‐000 Rev 0
21 | P a g e
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.
See Table 1.7 for a list of tested antenna recommendations. These antennas are FCC approved for use with the
Guardian. 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.
2.5.2 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.
2.5.3 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.
2.5.4 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.

Omni (Vertical Collinear)
Yagi
Vertical Dipole
Guardian Manual 001‐5006‐000 Rev 0
22 | P a g e
2.5.5 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 2.1 for a list of feedline recommendations.
Table 2.1 ‐ 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.
2.5.6 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.
RF E
Guardian Manual 001‐5006‐000 Rev 0
23 | P a g e
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.
2.6
TERRAIN AND SIGNAL STRENGTH
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, say 3‐5 miles, 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 losses. CalAmp
recommends a 30 dB fade margin for most projects.
Table 2.3 shows the RSSI versus Reliability.Table 2.3 RSSI Reliability

2.7
RADIO INTERFERENCE
Interference is possible in any radio system. However, since the Guardian 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.
a.
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.
Guardian Manual 001‐5006‐000 Rev 0
24 | P a g e
b.
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.
c.
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.
d.

Technical Services group has qualified personnel to help resolve your RF issues.

An RX/TX antenna is required for basic operation. For demo units only, connect the antenna as shown in Figure 3.1
to provide stable radio communications between demo devices.
Figure 3.1 ‐Demo Antenna Assembly
20 dB, 5 watt max, attenuator
Note:
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.
3.2
MEASURE AND CONNECT PRIMARY POWER
Primary power for the Guardian 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. (In Guardian Demo Kits, a
power connector with screw‐terminals is provided with each unit.) Observe proper polarity when connecting the
cables to the Power Supply. (White wire must be connected to red wire.)

UNIT IDENTIFICATION AND STATUS
Each Guardian has addressing capability which is used for diagnostics and remote commands only.
4.1.1.1
ID NUMBER
This value (maximum 1023) is assigned at the factory but may be modified using the Field Programming Software.
The ID Number is used to uniquely identify the Guardian for remote commands and Offline Diagnostics. The ID
Number may have values within the range of 1 to 4294967295 but multiples of 1024 should not be used
4.1.1.2
SHORT ID
This value (maximum 1023) is the low order 10 bits of the ID Number. It is used to identify online diagnostics only.
It may not be modified directly using the Field Programming Software; it is always derived from the ID Number. All
units within a network should have unique Short ID numbers to avoid ambiguity in Online Diagnostics reports.
The Guardian Field Programming Software may be used to check the value of the Short ID. When setting up a
network, we recommend checking each unit to make sure there is no duplication of Short ID numbers.
Duplications may be resolved by changing the Short ID Number.
If ID Numbers are set within the range of 1 to 1023, the ID Number and the Short ID will always have the same
value (see Table 1‐4).
4.2
DIAGNOSTICS
Guardian units continually monitor and report on their environmental and operating conditions.
4.2.1 ONLINE DIAGNOSTICS
Information is automatically sent by each unit at the beginning of every transmission.
May be disabled for back compatibility with Dataradio T‐Modem 96 or Motorola RNet 9600. Online Diagnostics
(statistics) require the use of a network configuration such as that specified in the “Network Using T‐Base” or
“Network Using GUARDIAN for Online Diagnostics” sections. Online diagnostics do not interfere with normal
network operation. Online diagnostics provide four types of information:

GUARDIAN FIELD PROGRAMMING SOFTWARE
INTRODUCTION
The Guardian Field Programming Software provides programming and diagnostics for the Guardian wireless
modem. The Field Programming Software allows the user to edit and program user programmable settings,
interactively tune modem and RF parameters, and monitor diagnostic data from the Guardian. See Figure 5‐1 for
the Guardian Field Programming Software startup screen.
Figure 5.1 ‐ Guardian Field Programming Software startup screen
This manual assumes the Field Programming Software has been installed on the user’s PC with at least one
operational serial COM Port available.
5.1.1 COM PORT SETTINGS
Guardian programming is done through the PC’s Primary COM Port. Primary and secondary COM ports are
configured with the Field Programming Software. The programming cable (included in the Programming Kit ‐ DRL
part number 250‐4006‐001) is connected from the Setup Port on the Guardian to the PC’s COM port configured as
the Primary Port.
The Port Settings screen of the Field Programming Software is accessed via the Utilities pull‐down menu (see
Figure 2‐7). The Port Settings screens are used to configure the PC’s serial COM Ports. COM Port parameters are
defined in 2.5.2.1. COM Port assignments are displayed in the bottom status bar of the Guardian Field
Programming Software screen.
5.1.2 COM PORT PARAMETERS
COM Port
Selects COM Port number (COM 1‐4) for Primary and Secondary COM Ports (see Figure 2‐6).
Baud Rate

used by the Read/Write Parameters screen for programming into nonvolatile memory.
Parameter settings are modified from three screen tabs: the Modem tab, COM/Analog tab, and Radio tab.
When desired parameters in each tab window have been adjusted, select the OK button to store the parameter
information into local PC memory and exit the parameter screen. Clicking the Default Parms button sets certain
parameters back to factory default settings. Clicking Cancel exits the parameter screen without modifying any
parameters currently stored in local PC memory.

Modem operating parameters include:
Long ID
The electronic ID Number is a unique number assigned at the factory. This number may be changed in the case of a
duplication. The ID Number is used by the programmer for remote addressing and diagnostics.
The range of this field is 1 to 4294967295 but multiples of 1024 should not be used. A multiple of 1024 results in a
Short ID of 0. If the ID Number is within the range of 1 to 1023, the Short ID will be the same.
NOTE: This ID is not the same as the printed serial number. Use the printed serial number to verify if the unit is
under warranty.
Short ID
The Short ID is derived from the longer ID Number. It is used to identify units and minimizes the time required to
transmit Online Diagnostics. The Short ID of each unit in a network must be unique if Online or
Offline Diagnostics will be used. Since the Short ID is derived from the ID Number, no entry is allowed in this field.
The range of the Short ID is 1 to 1023.
Comment
The Comment field can be used as a notepad (i.e., customer name, location, technical info...etc can be entered in
this field). Comments are text up to 39 characters including spaces.
Date Last Configured
The Date Last Configured field shows the date the unit was last programmed. The date is taken from the operating
program. No entry is allowed in this field.
Total Configurations
The Total Configurations field shows the number of times a unit has been programmed. No entry is allowed in this
field.
Online Diagnostics
If enabled, diagnostics information is sent at the beginning of each transmission. Diagnostics information is
invisible to user data except for the increase in RTS/CTS delay of 11ms (at 9600 b/s). The default value is “Enabled”
(checked).
All units in a network must use the same setting. Diagnostics from the last 15 stations heard are stored in each
unit. These values are read using the Offline or Online Diagnostics screen.
Transmitted information includes:
•
Short ID
•
Supply Voltage (in Volts)

•
Internal Temperature (in Celsius)

T‐Base Option
Available when connected to a GUARDIAN Wireless Modem, the “T‐Base Option” makes the necessary circuit
changes to allow using the modem as a special diagnostic unit in the T‐Base/R. The default value is “Disabled”
(unchecked).
Repeater Mode (Extended T1 RTS‐CTS refer to Table 2‐8, page 2‐13)
The Repeater Mode option extends transmitter turn‐on time to allow use in a repeater network. The default value
is “Disabled” (unchecked).
Extended Turn‐off (T2)
The Extended Turn‐off option extends transmitter turn‐off time to enforce a quiet period at the end of each
transmission. Select “Enabled” if data equipment does not clearly terminate each data frame and is susceptible to
extraneous bits (dribble bits) at the end of data transmission. The default value is “Disabled” (unchecked).
Values are: 4800 b/s = 16 ms; 9600 b/s = 8 ms; 19200 b/s = 4 ms
An end‐of‐transmission quiet period approximately 8 characters long can be invoked on the GUARDIAN by holding
its transmitter on briefly after RTS is dropped. This quiet period (which occurs between the last valid data
character and any possible extraneous “noise” bits) may be of benefit to some DTE that would otherwise be
adversely affected by the extraneous bits.
Output Raw Diagnostic Data Only
The Output Raw Diagnostic Data Only option instructs the modem to receive diagnostic information received from
other modems only. Enabling this option disables user data delivery. This function is provided to use with the
Diagnostic Unit incorporated in a T‐Base or T‐Base/R. The default value for this option is “Disabled” (unchecked).

Tx Only Radio
The Tx Only Radio option disables the radio’s receiver and any ability for the modem to receive data. This function
is provided for use with the Tx unit incorporated into a T‐Base or T‐Base/R.
Rx Only Radio
The Rx Only Radio option disables the radio’s transmitter and any ability for the modem to transmit data. This
function is provided for use with the Rx unit incorporated into a T‐Base or T‐Base/R.
PTT Watchdog
The PTT Watchdog allows the user to set the maximum transmit time. This is used to protect against a ‘stuck’
transmitter. The time is selected by a slider bar. The range is 0 to 120 seconds with a default of 30 seconds.
Warning: Transmissions longer than 30 seconds may exceed the duty cycle rating of the transmitter and lead to
shortened life or transmitter failure. A factory‐installed cooling fan is available for extended duty operations. For
continuous‐transmit applications, the PTT Watchdog feature can be disabled (unchecked).
Synthesizer
This field lists the synthesizer model used. This field is non‐selectable and for reference only.
Dynamic Carrier Detect Off Threshold
The Dynamic Carrier Detect Off Threshold allows the modem to automatically adjust the Carrier Detect Off
Threshold based on the RSSI while receiving data. If selected, the Carrier Detect Off level will automatically adjust
to approximately 15 dB below the actual signal strength. This provides rapid detection of loss‐of‐carrier and
minimizes or eliminates ‘bit dribble’ at the end of transmissions.
Recommendation: Keep Dynamic Carrier Detect Off Threshold enabled (checked) unless interference or variable
signal strength (i.e., fading in a moving vehicle) causes problems.
Carrier Detect On Threshold
Carrier Detect On Threshold indicates RSSI level when a carrier is found. This level should be more than the Carrier
Detect Off Threshold.
Carrier Detect Off Threshold
Carrier Detect Off Threshold indicates the RSSI level when a carrier is lost. This level should be less than the Carrier
Detect On.

END TO END TEST
Two Dataradio GUARDIANs can be tested using the Dataradio GUARDIAN Field Programming Software. The Field
Programming Software has several useful utilities embedded in the program that assist in testing the wireless
modems. The testing setup requires a computer running the Field Programming Software attached to each user
COM port on the GUARDIAN wireless modems. The Utilities will allow the user to send ASCII text or Hex characters
through the GUARDIANs being tested.
The GUARDIANs must be setup so that they have the appropriate receive and transmit signal levels for the test.
The signal strength will be much stronger if the units are tested on the bench compared to being tested in a field
installation. These signals must be attenuated or the output power level adjusted if the units are being tested on
the bench.
Guardian Manual 001‐5006‐000 Rev 0
58 | P a g e
Under the “Utilities” menu choose the “ASCII Terminal”. From the “ASCII Terminal” screen, choose the “Primary”
selection. This will open an ASCII terminal window using the primary COM port of the computer. This procedure
should be done for both GUARDIANs. The ASCII Terminal utility has provisions for transmitting the ASCII data,
displaying received ASCII data and displaying ASCII transmitted data. Figure 2‐23 shows the window for the Primary
ASCII Terminal.
Figure 2‐23 End to End Test: ASCII Terminal
Figure 2‐23 also shows the area that is used to send an ASCII text message. The ASCII data message is typed into
this area. The ASCII text message is then sent out the first GUARDIAN through the computer’s primary port once
the “Send “button is clicked. The sent ASCII message is then displayed in the Tx Data area of the ASCII Terminal
window as shown in Figure 2‐24.

Figure 2‐24 End to End Test: Text message sent
The ASCII message is transmitted to the other GUARDIAN. The ASCII terminal program will display the received
ASCII message in the Rx Data area as shown Figure 2‐25.

If the message was not displayed as typed, then a problem may exist in the system. Check all parameters and
connections in the system. The signal level should also be checked again. The GUARDIAN’s Link Test utility can be
used to verify a communication path.
The previous procedure can also be used with the Hex Terminal utility. When the Hex Terminal is used, the
information is entered as hex code. Figure 2‐26 shows how the information will look when it is typed in and sent in
hex.
Figure 2‐26 Hex Terminal
In the Hex Terminal mode, the program will not transmit ASCII information. It will only allow valid hex characters.
