Features:
- Supports point-to-point, point-to-multipoint, and broadcast modes.
- Inverted RS232 interface at 5V or 3V CMOS level.
- DTE speed ranges from 600 to 115200bps, with throughput up to 28kbps without acknowledgments.
- Operates on a single 5V or 3V supply with low power consumption.
- Available frequencies: 869.85MHz (EU) and 914.50MHz (North America).
- Usable range up to 200m.
- Conforms to ETSI and FCC standards.
Applications: Ideal for telemetry, telecontrol, EPOS equipment, remote data acquisition, environmental monitoring, security systems, and fleet management.
Functional Description: The RPM3 is a connection-oriented modem that ensures error-free data transmission using bit coding and checksums for data validation.
Operating States:
- Shutdown: Activated by asserting the WAKE/DTR pin high, suspending communications.
- Standby: Default state awaiting connection requests.
- Connected: Active state for data transmission upon receiving a connection request.
Host Interface: Utilizes a full duplex serial interface with baud rates from 600bps to 115200bps, including control signals for flow control and power saving.
Technical Specifications:
- Operating voltage: 5VDC or 3VDC.
- Current consumption averages 15mA during data streaming.
- Standard operating frequencies: 869.85MHz (EU) and 914.50MHz (USA, Canada).
- Operating temperature range: -20ºC to +70ºC.
Configuration: Configurable via a built-in command line configurator, with key parameters including unit and site numbers, baud rate, data throughput, flow control, and retry attempts.
