Market Applications

Selectable Operating Modes

Selectable operating modes provide flexibility: RS-232, RS-422, and RS-485 compatible; simplex, half-duplex or full-duplex operation; RTS-CTS handshaking protocol or
data activated transmission (DOX) mode. Transparent, asynchronous serial formats are supported, such as Modbus™, Modbus-RTU™, AB DF1™, and various other protocol formats.

Guardian is also selectable for analog operation: paging, phone line substitution, slow speed data applications, 600 ohm or high impedance audio input/output

High-Performance & Reliable

Real-time, non-intrusive online diagnostics report received signal strength (RSSI), RF power output, supply voltage, and other radio performance statistics. Field Programming Software offers unit programming, link testing, and RF path verification. CalAmp products are covered by a standard one-year warranty.

Centralized Management Platform

When combined with CalAmp’s secure web-based platform, DeviceOutlook provides a robust solution to better manage, monitor, and control devices remotely. The application non-intrusively monitors system diagnostics and updates firmware and configuration change over-the-air to reduce costs and improves operational efficiencies.
