uWave Max OEM - Underwater acoustic modem Device specifications |
KEY FEATURES
- Extremely small dimensions and weight
- Reliable data transmission at 78 bps
- Communication range up to 30001, 2 m
- Code division of subscribers
- Measurement of signal propagation time
- Highly reliable digital broadband acoustic communication technology
- Low power consumption (Rx/Tx) 0.33/15 W
- Open pairing protocol
- Batch transmission with guaranteed delivery and acknowledgement
DESCRIPTION
uWave Max OEM is based on UTRO platform and is supplied as a printed circuit board module with RT-1.524525-1 transducer.
With the uWAVE Max OEM modems, the user can:
- transfer arbitrary digital data between devices uWave USBL Modem, uWave Max and uWave in any combination;
- transmit up to 9 code user commands of telecontrol;
- request from remote devices uWave USBL Modem, uWave Max and uWave their depth, temperature and supply voltage;
- transfer data in batch mode with acknowledgment (ALO - At-least-once)
- measure its own supply voltage;
Devices from uWave family use a simple open NMEA-like configuration protocol, and the supplied open-source libraries uWaveLib (.NET) and uWave ALib (Arduino) allows for the fastest and easiest integration of devices into custom solutions.
Differences from the basic version uWave:

1 A parameter that determines the maximum range at which a signal can be received based on the electro-acoustic parameters of the transmitter and receiver, spatial decrease in the intensity of sound energy, attenuation in the medium and acoustic noise level.
2 When working with another uWave Max/uWave Max OEM or when working with uWave USBL Modem. The maximum communication range with standard modems uWave is 1000 meters.
3 This value is obtained without the presence of the multipath effect.
