Data rate modes
All devices of the family can work with alternative firmware supporting different data rate modes of communication. The modes are not compatible with each other. The mode is changed by re-flashing the device.
| STRONG | EASY | LITE | HASTE | |
|---|---|---|---|---|
| Data rate, bit/s | 78 | 156 | 314 | 634 |
| Maximum range, m | 1000/30001,2 | 8001 | 7001 | 5001 |
| Number of code channels | 20 | 14 | 7 | 3 |
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, the spatial decrease in the intensity of sound energy, attenuation in the medium and the level of acoustic noise.
2 When uWave Max OEM, uWave Max and uWave USBL Modem are operated in any combination. The maximum communication range with standard uWave modems is 1000 meters. The parameter is specified for the standard data rate mode - 78 bit/s.
3 The standard data rate mode of 78 bit/s provides the maximum communication range and noise immunity. Other modes are provided by re-flashing the devices.
4 The maximum depth is determined by the transducer. The modem’s printed circuit board must be located in the user’s one-atmosphere (normobaric) housing.
5 Operating depth of 1000 meters is provided when working with the RT-1.524525-1-FF transducer.
