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 is 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). 1.
1.3 LINK CONFIGURATIONS The Guardian allows you to program up to eight (8) different link configurations. You may choose which configuration you are using by selecting the appropriate link configuration pins. Since the pins are internally pulled High, a No Connect (NC) will result in a High state. Tie the pin to Ground (GND) to pull it Low. See Table 3 for the User Interface Port.
1.4 PHYSICAL DESCRIPTION Guardian consists of two 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.

1.5.2 ACCESSORIES AND OPTIONS The following tables list Guardian Demo Kits and standard accessories tested and approved for use with the Guardian.
2 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).
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.
2.2.6 NETWORK USING A GUARDIAN FOR ONLINE DIAGNOSTICS The Network Using a Guardian for Online Diagnostics configuration has the following characteristics. • • • • Master station may be full duplex (duplexer dual antennas required), half duplex or simplex. Accumulated online diagnostics 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.
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.
blowing across the antenna, precipitation hitting the active element, or other environmental causes. As static charge builds up on the antenna’s active element, over a period of minutes or even hours, the DC blocking capacitor inside the lightning arrestor is charged.
2.5.4 GOOD DESIGN PRACTICES There are two relatively easy ways to avoid creating large transients due to static buildup on an antenna and the subsequent firing of the gas discharge tube in the lightning arrestor. Following either or both of the recommendations below will eliminate this potential problem. 1. Use antennas with a DC grounded active element.
2.6.2 OMNI-DIRECTIONAL ANTENNA In general, an omnidirectional 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.
Table 12 Transmission Loss (per 100 Feet) Frequency Range Cable Type LMR-400 1/2” Heliax 7/8” Heliax 1-5/8” Heliax VHF UHF 900 MHz 1.5 dB 0.68 dB 0.37 dB 0.22 dB 2.7 dB 1.51 dB 0.83 dB 0.51 db 3.9 dB 2.09 dB 1.18 dB 0.69 dB 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.
2.7 TERRAIN AND SIGNAL STRENGTH A line of sight (LOS) 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.
3 SETUP AND CONFIGURATION 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 the following figure to provide stable radio communications between demo devices.
2. Keeping the Insertion Tool in place, insert wire (28 AWG minimum, 18 AWG maximum) into the wire hole. 3. Remove Insertion Tool. Check wire connection. 3.4 CONNECT GUARDIAN TO PROGRAMMING PC Connection to a Guardian is established through an RS-232 (straight through) or (non-null) cable connected to the setup port of the Guardian and the COM port of the PC. 3.5 GUARDIAN FIELD PROGRAMMING SOFTWARE Operating characteristics of the Guardian are configured by the Field Programming Software.
4 UNIT STATUS In addition to unit status information provided by the five tricolor LEDs in the LED Panel, unit status information is also displayed in the Diagnostics pane of the User Configuration window (page 26 for Modem mode or page 35 for Loader Mode) of the Guardian Field Programming Software, and is explained in Chapter 5. 4.1 UNIT IDENTIFICATION AND STATUS Each Guardian has addressing capability which is used for diagnostics and remote commands only.
4.2.1 ONLINE DIAGNOSTICS Information is automatically sent by each unit at the beginning of every transmission. Online Diagnostics (statistics) require the use of a network configuration such as that specified in the “Network Using a Guardian for Online Diagnostics” section 2.2.6. Online diagnostics do not interfere with normal network operation. Online diagnostics provide four types of information. • • • • • • • Short ID RSSI Temperature Battery Forward Power Reverse Power Time See section 5.
5 5.1 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 the following figure for the Guardian Field Programming Software startup window.
Figure 13 Guardian Programmer Window Guardian programming is 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 Demo Kit) is connected from the Setup Port on the Guardian to the PC’s COM port configured as the Primary Port. 5.
COM Port Selects COM Port number (1- 32) for Primary and Secondary COM Ports. Default is COM1. Baud Rate Selects the communication speed for Primary and Secondary COM Ports. Default is 57600 bps. Data Bits Selects number of data bits (7 or 8) transmitted or received for the Primary and Secondary COM Ports. Default is 8. Parity Selects transmission or reception of any Parity bits for the Primary and Secondary COM Ports. Default is None.
5.4 PORT STATISTICS The Port Statistics window is accessed via the Utilities menu. Port Statistics show current parameters of the PC’s Primary and Secondary COM Ports. Figure 15 Port Statistics Window Baud Rate Baud Rate shows the current baud rate setting for the Primary and Secondary COM ports. RTS RTS shows the current state of the RTS (request to send) line. RTS is an output from the PC. DTR DTR shows the current state of the DTR (data terminal ready) line. DTR is an output from the PC.
5.5 USER CONFIGURATION — MODEM MODE The User Configuration window is accessed from the Utilities menu or the Config button on the tool bar. To put the Guardian in Modem mode, select Modem in the Mode field. Figure 16 User Configuration Window – Modem Mode 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 80 characters including spaces.
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.

The Guardian allows you to configure up to eight (8) separate Link Configurations for the unit. The Link Configuration the unit utilizes is selected by the Configuration Select lines on the User connector. Link Configuration settings are modified from three sections on this window: Modem Settings, RF Link, and COM Port. When desired parameters in each tab window have been adjusted, click Save Changes to store the parameter information into local PC memory and close the window.
5.6.1 MODEM SETTINGS Figure 19 Modem Settings panel 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 bits per second). The default value is Enabled (checked). Note: All units in a network must use the same setting. Diagnostics from the last 15 stations heard are stored in each unit.
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. Rx-Only Radio The Rx-Only Radio option instructs the modem to receive data and diagnostics from other modems only.
Rx Frequency Displays the receive frequency for the channel pair. Tx Frequency Displays the transmit frequency for the channel pair. Power Output Displays the transmit power value for the channel pair. The default value is 5.0 Watts. This value should not be changed from the default value unless a lower power is required to meet regulatory requirements.
