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.

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 10
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.

1.3.4 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.

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.
Figure 2.1 – Point-to-Point Network
001-5006-000_FCC.docx Page 18
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
001-5006-000_FCC.docx Page 19
Online diagnostics are available using the Online Diagnostics utility without disrupting
network activity
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)
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:
Master station and all remotes must be half duplex
Networks described in Section 1.10.2, 1.10.3, or 1.10.5 may be used with a T-Base
repeater
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:
Master station may be half duplex or simplex
Accumulated online diagnostics for a maximum of 15 stations are available at a
monitoring site (monitoring site must be in range of all remotes)
Online Diagnostics are available in real time at the monitoring site
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
001-5006-000_FCC.docx Page 20
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.
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:
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
These requirements can be quickly determined in most cases.
001-5006-000_FCC.docx Page 21
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.
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.
001-5006-000_FCC.docx Page 22
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.
Figure 2.4 - Antenna Types
Omni (Vertical Collinear)
Yagi
Vertical Dipole
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.
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.

Approximately 90% reliability. Fading will cause occasional data loss.
-80 dBm
Approximately 99% reliability. Reasonable tolerance to most fading.
-70 dBm
Approximately 99.9% reliability with high tolerance to fading.
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.
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. 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.

It is easy to set up a Guardian network to verify basic unit operation and experiment with
network designs and configurations.
3.1 INSTALL THE ANTENNA
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
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.)
3.3 CONNECT GUARDIAN TO PROGRAMMING PC
Connection to a Guardian is established through an RS-232 cable connected to the setup
port of the Guardian and the COM port of the PC
3.4 GUARDIAN FIELD PROGRAMMING SOFTWARE
Operating characteristics of the Guardian are configured by the Field Programming
Software. Offline Diagnostics and Online Diagnostics give access to Offline Diagnostics and
commands (local and remote) and online diagnostics monitoring (with or without a T-
Base/R). Programming software is Windows® based and requires a Windows 95 or better
operating system. Context sensitive help and printable help files are provided with this
program.
The GUARDIAN requires the use of the Field Programming Software for
configuration, adjustment and diagnostics.

The Unit Status windows display device General and Diagnostic information.
4.1 UNIT IDENTIFICATION AND STATUS
Each Guardian has addressing capability which is used for diagnostics and remote
commands only.
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
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:
DC Input Voltage
Transceiver Temperature
PA Forward Power
PA Reverse Power
4.2.2 Offline Diagnostics
Offline diagnostics are statistics returned in response to a specific request to a particular
station. The use of this feature requires temporary suspension of user network operation.
Offline diagnostics provide information that is displayed via the Offline Diagnostics utility.
Offline Diagnostics gather and displays five types of information:
001-5006-000_FCC.docx Page 27

5 Using Guardian Software
2.5 GUARDIAN FIELD PROGRAMMING SOFTWARE
2.5.1 Introduction
The GUARDIAN Field Programming Software provides programming and diagnostics for the Dataradio
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 2-6 for the 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.
2.5.2 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.

2.5.2.1 COM Port Parameters
COM Port
Selects COM Port number (COM 1-4) for Primary and Secondary COM Ports (see Figure 2-6).
Baud Rate
Selects the communication speed for Primary and Secondary COM Ports.
Data Bits
Selects the number of data bits (4-8) transmitted or received for the Primary and Secondary COM Ports.
Parity
Selects transmission or reception of any Parity Bits for the Primary and Secondary COM Ports.
Stop Bits
Selects number of Stop Bits (1 or 2) transmitted or received for the Primary and Secondary COM Ports.

001-4006-101
DTR Enable
Used to assert DTR (Data Terminal Ready) line of the RS232 Port when the port is open for the Primary
and
Secondary COM Ports.
Swap COM Ports
Selecting the Swap Com Ports button moves the Secondary COM Port settings to the Primary COM Port
(and moves the Primary COM Port to the Secondary settings). Since GUARDIAN programming is done
through
the Primary COM Port, this is useful when two units are connected to the Primary and Secondary COM
Ports. A Swap COM Ports allows the second unit to be programmed without switching programming
cables.
2.5.2.2 Primary and Secondary Port Settings Communications Modes

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
001-5006-000_FCC.docx Page 31
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)

Transmitted information includes:
� Short ID
� Supply Voltage (in Volts)
� Internal Temperature (in Celsius)
� Forward and Reverse Power (in Watts) (T-96S and GUARDIAN only)
� Received Signal Strength (in dBm)
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
001-5006-000_FCC.docx Page 32

Program Firmware option. Select Modem Code File allows the user to select the file to program the
firmware in the GUARDIAN.
2.5.17 END TO END TEST
Two Dataradio GUARDIANs can be tested using the Dataradio GUARDIAN Field Programming
Software. The Field
001-5006-000_FCC.docx Page 49
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.
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.
2-36
001-4006-101
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.
001-5006-000_FCC.docx Page 50
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.
Type in this area to send the text message

001-4006-101
Figure 2-25 Text message received
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.
001-5006-000_FCC.docx Page 51
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.
