Modem M64

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:

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.)
• Depth rated to 300 meters.
