  • Description

Description

The Modem M64 is a two-way half-duplex 64bps acoustic modem with a robust and user configurable data link.

The M64 sets a new market standard with its record-breaking physical size, low power requirement and cost. All this combined with a very useful technical specification, the M64 opens new possibilities for underwater communication in both existing and new areas.

Key Specifications:
Max range
200
meters
Speed
64
bps, both ways
Communication
Two-way
half duplex
Typical Applications
  • AUV telemetry
  • ROV wireless control
  • Wireless subsea sensors
  • Research projects
  • Any scenario where you need to wirelessly control and monitor subsea equipment
Key Features
  • Omnidirectional operation which will keep the data link stable even when the modem is in motion and/or being rotated around its axes.
  • Fully self-contained with no requirements for external computers, top-side controllers or other devices.
  • Packet based protocol with extensive use of error detection to enable a highly robust transmission.
  • Wide range of available frequencies enabling easy adaptation to local environments
  • The integrated status LED makes it easy to confirm that the communication link is established and when data is transferred.
  • Serial 115200 baud UART 3,3V interface makes the M64 easy to integrate with other subsea equipment like sensors, ROVs and AUVs.
  • Easy to use API to transmit/receive packages etc.
  • Can operate simultaneous with Underwater GPS.
  • Extremely small size enabling easy integration in other equipment.
  • Very low power consumption.
  • Highly robust operation, also in areas with acoustic reflections (shallow water, around installations etc.)
  • Standard depth rated to 300 meters. Other depth ratings available on request.
