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).
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.
The front panel has the following connections: (1) 8-Pin user interface block connector (1) 50-ohm TNC female Antenna connector (1) 50-ohm SMA female receive antenna connector (Dual-Port models only) (1) Right-angle power connector (10-30 VDC) (2) DE-9F RS-232 ports For Dual-port Guardian connections, see Section 1.3.6. 1.3.2 LED Panel The LED panel has five Tri-Color LEDs. The functionality of each LED is shown in Table 1.1. Table 1.
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.
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.

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.
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.
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.
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.
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.

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.
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 2-37 001-4006-101 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 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. 001-5006-000_FCC.
