    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 CalAmp provides are used in a normal manner with a well- constructed network. These products 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 or death, or loss of property.

  • Page 8: Guardian Overview

    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.

  • Page 9: Link Configurations

    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.

  • Page 10: Physical Description

    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.

    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.

  • Page 20 Figure 9 Voltage Transient immediately after the gas tube turns on During testing, transients were measured on the antenna port of CalAmp’s Viper at voltage levels up to +/-280V. These voltage transients often have high frequency content that can easily pass through any filtering in the radio and damage components in the transmitter and receiver circuitry.

  • Page 21: Good Design Practices

    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.

  • Page 22: Omni-Directional Antenna

    The cable should be kept as short as possible to minimize signal loss. See the following table for a list of feedline recommendations. | Page 15 Guardian™ Serial Modem or Analog Radio for Licensed Spectrum PN 001-5006-000 Rev. 3...

  • Page 23: Rf Exposure Compliance Requirements

    2.6.6 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.

  • Page 24: Terrain And Signal Strength

    Approximately 99.9% reliability with high tolerance to fading. 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.

  • Page 25: Setup And Configuration

    Primary power for the Guardian must be within 10-30 VDC and be capable of providing a minimum of 10 watt supply for the Tx at 1 W, 40 watt supply for Tx at 5 W, or 60 watt supply for Tx at 10 W.

    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 Long ID Number.

  • Page 28: Online Diagnostics

    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.

  • Page 29: Guardian Field Programming Software

    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.

  • Page 30: Port Settings

    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.

  • Page 31: Primary And Secondary Port Settings Communications Modes

    Clicking 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.
