1.3 Interface Unit
The Interface Unit IF-8000 is supplied with the blackbox-type system, and is optional with the
standard type system. It can be mounted on the deck, a desktop or a bulkhead. Select a
mounting location for it considering the following:
•
Locate the unit away from areas subject to water splash.
•
The length of the cable to processor unit is 10 max.
•
Leave sufficient space around the unit for maintenance and servicing. Recommended
maintenance space appears in the outline drawing at the back of this manual.
•
For mounting on a bulkhead be sure the mounting location is strong enough to support the
unit under the pitching and rolling normally encountered on the vessel.
Tabletop or deck mounting: Fasten with four self-tapping screws.
Bulkhead mounting: Screw in self-tapping screws for the upper fixing holes, leaving 5 mm
protruding. Set the interface unit to the screws. Screw in screws for lower fixing holes and
tighten. Finally, tighten screws in upper fixing holes.
1.4 Transducer
The performance of the video sounder depends upon the transducer position. A place least
affected by air bubbles should be selected since turbulence blocks the sounding path. Further,
select a place least influenced by engine noise. It is known that air bubbles are fewest at the
place where the bow first falls and the next wave rises, at usual cruising speed. In small,
slow-speed boats, the position between 1/3 and 1/2 of the ship’s length from the bow is usually
a good place.
Note: The face of the transducer must be facing the sea bottom in normal cruising trim of the
boat.
1.5 Booster Box (option)
The Booster Box enables connection of a 5 kW transducer (28F-38M, 50F-38). You can also
connect a 10 kW transducer (28F-72, 50F-70), however the maximum output power will be 5
kW
. For further details see its operator’s manual.
