1. HIGH SPEED SERIAL CONNECTIVITY FOR REMOTE MONITORING & CONTROL The Guardian wireless modem provides a high-speed data link suitable for a wide variety of applications requiring system security and diagnostic reporting. Designed for speed and efficiency, Guardian provides over-the-air data rates up to 19.2 kbps in a 25 kHz channel. 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 selection. 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 Experience The Advantage 1-10 Watts (1-8 W MAS) Continuous Duty; software selectable 10-30 VDC Wide Range Power Supply On/Offline Diagnostics for Network Health & Status User selectable data rates: 4,800, 9,600, 19,200 kbps OTA compatible with T-96SR and TSLM Flexible, programmable External I/O interface RS-232, RS-422, RS-485 OTA compatible with DL-3400 and JSLM analog product lines Datasheet Guardian ™ Serial Modem or Analog Radio for Licensed Spectrum
