PMM4511 OEM Acoustic Modem

The PMM4511 is a compact and efficient underwater acoustic modem designed for reliable communication and data acquisition in challenging marine environments. This OEM modem is well-suited for integration into ROVs, AUVs, and scientific instruments, offering adaptable acoustic links and onboard processing in a slim, low-SWaP form factor.

Interfacing is versatile, with support for RS-232, RS-422, and Ethernet connections. Developers can utilize Python, MATLAB®, C++, and MARIA APIs, as well as an integrated shell, JSON, and web interface for streamlined integration. The PMM4511 also provides robust data logging, recording PCM data in passband or baseband directly to internal storage, expandable with microSD, or streamed via TCP/IP.

Advanced Capabilities

• Slim OEM Design: Measuring 173 × 38 × 28 mm and weighing only 170 g, the PMM4511 is optimized for embedded applications.
  
  
• Flexible Data Rates: Supports multiple modulation schemes from 80 bps (FH-FSK) up to 10,240 bps (PSK), adaptable to a wide range of link conditions.
  
  
• Efficient Processing: A 1.4 GHz ARM® Cortex®-A53 processor running Debian Linux supports user applications and automated control.
  
  
• Low Power Modes: Acoustic wake-up and sub-watt receive power enable long-duration deployments with minimal energy use.

Specialized Features

• Accurate Acoustic Ranging: Provides sub-meter ranging precision (<0.3 m).
      
• Comprehensive Interfaces: Ethernet, RS-232, RS-422, GPIO, SPI, I²C, and analog connections expand integration options.
  
  
• Secure Communication Option: Phorcys Stheno licensing available for secure networked operations.
