DO NOT use variable power supply whose maximum supply voltage is higher than the above rated voltage.
DO NOT use switching mode DC power supply.
Depth Rating: 300m
Shut-down Control: Specify when ordering
1. Manual Shutdown (default)
    Open: Operating
    Short to Common: Shut down
    Switch, relay, optocoupler etc. can also be used for "connecting" and "disconnecting", and voltage protection
    rating of these "switch" devices must be greater than power supply voltage level.

2. Digital Output
    TTL/CMOS Compatible: Logic Low: 0 to 0.8V; Logic High: 3.5 to Vcc (Vcc: Power Supply Voltage).
    Logic High: Operating
    Logic Low: Shut Down
    Voltage protection rating of Digital Output must be greater than power supply voltage level.
Receiving  
Signal Type: Single-ended
Receiving Sensitivity: -193 dB + Receiving Gain, V/μPa
Receiving Gain:  0, 20, 40, 60dB
Gain Selection: Two Digital Signals A1, A0 and Digital Common.
1. Wires (Manual)
    Open: High or Digital "1".
    Short to Common: Low or Digital "0".
    Switch, relay, optocoupler etc. can also be used for "connecting" and "disconnecting", and voltage protection
    rating of these "switch" devices must be greater than power supply voltage level.

2. TTL/CMOS Compatible: Logic Low: 0 to 0.8V; Logic High: 2.4 to Vcc (Vcc: Power Supply Voltage).
    Note: voltage protection rating of Digital Outputs must be greater than power supply voltage level.

BII-8060 Troubleshooting
Issue No Sound Generation
Possible Reasons 1. Shut-down wire is short to common, shield or digital low.
2. After shutting down, shut-down wire is not away/off common fast enough. or, rise edge from digital low to high is not sharp enough.
Solutions Connect shut-down wire to common, then move away as fast as possible, or improve the rise edge of digital low to high.
