F4105-AU Acoustic wake-up unit Device specification |
FEATURES
- Ease of use
- Minimal dimensions, weight and power consumption
- Ability to set one of 64 unique addresses
- Activation range up to 2001 meters
- Maintenance-free potted housing
DESCRIPTION
The miniature acoustic wake-up unit is designed for long-term standby while awaiting an underwater acoustic wake-up signal. When it receives a code matching the code programmed into its non-volatile memory over the underwater acoustic channel, it drives the WAKE cable wire to logic high for 90 seconds.
The F4105-SU surface control unit is used to program the device address and send the wake-up signal.
