uConnect is the world smallest underwater acoustic digital modem, which allows to communicate up to 20 subscribers in area 1000 x 1000 meters with both transparent channel and predefined code messages/telemetry transmission. Extremely small size, low power consumption and simplicity of usage make uConnect an ideal solution for AUV control as well as data transmission, where dimensions and weight are the bottleneck.
The device allows:
transfer data in transparent channel mode - just connect the modem to a serial port
request the depth, temperature, supply voltage of remote modems with simultaneous measurement of the signal propagation time (and hence the distance to them)
transfer data in batch mode with guaranteed delivery (ALO - At-least-once) and delivery notification
measure immersion depth, water temperature, and supply voltage of local modem.
uConnect modems use a simple open NMEA-like configuration protocol, and the supplied open-source libraries allows for the fastest and easiest integration of devices into custom solutions.
