MB1
User Manual
Turning the unit over, the transmit array (the larger black square) and the receive array (the smaller black
square) can be clearly seen. A carrying handle is located at one end of the base of the unit, and may
also be used as a tie off point to prevent loss in the event that the sonar mount was to break.
3.1.1

Optional Internal Motion Sensor

If the unit has been supplied with an internal motion sensor, this can be used instead of an external
sensor to correct for vessel motion. The advantage of the internal sensor is reduced set up time (the
cabling is already in place and offsets do not need to be measured between the sonar and the motion
sensor) and also in vessels with temporary mounts the mount flex will be measured by the motion sensor.
3.1.2

Maintenance

The sounder should be kept clean and free from marine growth where possible. Although the system has
been manufactured using corrosion resistant materials, it is prudent to inspect and clean the sounder at
regular intervals, especially if it is to be immersed in water for long periods of time.
Special care should be taken to ensure the transmit and receive arrays are kept free from growth and are
not scratched in any way. A non-abrasive cleaning product should be used to clean the unit, then it is to
be stored in a dry environment.
Caution: Care must be taken not to scratch the transmit and receive array. Ensure
it is placed on a clean surface free from items that may damage these sensitive
components
Regular application of silicone grease or equivalent is recommended on the Digibar V connection plug to
prevent corrosion and wear.
The transmit and receive arrays are not to be coated with any form of paint, including antifouling. This will
interfere with the correct operation of the acoustics.
3.1.3

Handling

The sounder may or may not have an enclosed motion sensing unit, depending on the configuration
purchased. In either case, it is important to ensure that the unit is not dropped or suffers any shock
damage. This may either damage the internal components or offset the alignment between the arrays.
Warning: Care is to be taken to avoid shock damage to the unit, especially in
transit. Always ship the unit using the supplied shipping container.

Real Time Appliance (RTA)

The RTA is the center of the MB1 system. It serves as the connection box for all the sensors as well as
providing better than 1 ms timing on all sensors including the sonar.
The front panel of the RTA has status LEDs that indicate whether data has been received from the sensor
and the rear panel has all the connections to the sensor.
