used as a stand-alone master instrument or set to repeat depth and speed
information from the SeaTalk bus.
The ST30 Bidata will display the following information:
• Water depth
• Shallow water alarm
• Deep water alarm
• Keel/Waterline offset
• Minimum depth
• Boat speed
• Log
• Trip
• Maximum speed
• Average boat speed
• Illumination level

1.1 Siting
The ST30 Bidata instrument may be installed above or below deck where
it is:
• easily read by the helmsman (normally viewed at eye level)
• protected from physical damage
• at least 230mm (9in) from a compass
• at least 500mm (20in) from radio receiving equipment
• accessible from behind for ease of installation and cable running
Notes: To prevent the build-up of moisture, the instrument breathes
through the back cover. The instrument must, therefore, be mounted
where the back cover is protected from direct water.
The rear case is fitted with a foam gasket to form a water-tight seal
between the instrument and the installation face.

1. Make sure the surface to which the instrument (1) is to be mounted is
smooth and flat.
2. Use the fitting template (supplied) to mark the centres for the two
fixing holes and the instrument connector boss.
Note: To allow for the fitting of protective covers, adjacent
instruments must have a 6mm (1/4in) gap between them (116mm
centre to centre min.).
3. Drill two 5mm (0.2in) diameter holes for the fixing studs (2).
4. Using a 60mm (2 3/8in) diameter cutter, drill a location hole for the
instrument connector boss.
5. Connect the power supply and transducer cables to the back of the
instrument (1) (see relevant installation sections).
6. Screw the two fixing studs (2) into the back cover.
7. Install the instrument (1) and secure with the thumb nuts (3) provided.

the rear of the instrument. Run the free end back to the vessel's
distribution panel.
2. Cut the cable to length and connect the red wire to 12V and the

The ST30 Bidata is supplied with a daisy-chain cable that allows adjacent
ST30 instruments to be linked together. The daisy-chain cable supplies
power to adjacent instruments and allows data to be transmitted and
received via the SeaTalk bus.
The daisy-chain cable plugs into one of the SeaTalk ports on the back
cover.

2.3 Paddlewheel replacement
If the high speed paddlewheel (supplied) is to be fitted, or the existing
paddlewheel to be replaced, proceed as follows:
1. Remove the retaining rings (1) and pin (6) from the speed
transducer (3).
2. Withdraw the speed transducer (3) from the through hull fitting (4).
3. If replacing a worn paddlewheel and if the vessel is still in the water,
replace the speed transducer (3) with the plug (5).
4. Remove the pin (6) that retains the paddlewheel (7) in the speed
transducer (3). This is a simple press fit into the transducer housing.
5. Fit the high speed/replacement paddlewheel (7) to the speed
transducer (3) and retain with the pin (6).
Note: The paddlewheel is correctly orientated when the working (flat)
surfaces of each paddle are facing forwards.
6. Assemble the speed transducer (3) to the through hull fitting (4) and
secure with the retaining rings (1) and pin (2).

2.4 Installation
The depth and speed transducers are supplied with detailed installation
and maintenance instructions. These instructions, together with following
notes, should be read thoroughly before attempting to install the
transducers.
Speed transducer (through hull)
For accurate speed readings, locate the speed transducer in the shaded
''clear flow' areas as shown.
D587
The transducer should also be:
• ahead of propellers (10% W.L. length minimum)
•
at least 150mm (6in) from the keel (with sailing yachts siting should be
forward of the keel)
• near the centreline of the vessel
• clear of other through hull fittings or projections
• have sufficient clearance inside the hull to allow the nut to be fitted
• have 100mm (4in) clearance above the through hull fitting for
withdrawal
Note: The speed transducer can, if required, be shortened. However, new
1/8in spade connectors must be crimped to the shortened cable.

Chapter 2: Transducer Installation
Siting of depth transducer (Standard through hull)
The depth transducer must be vertical to within 10°, forward, aft and
athwart ships.
10° Max
D630
2.5 Cabling
Run the transducer cable back to the instrument. Avoid fluorescent lights,
engines, radio transmitting equipment and, in the case of the depth
transducer, avoid the speed transducer cable. The cables should also be
kept clear of the bilgeÕs and be secured at regular intervals.
Note: The depth transducer cable must not be shortened.
Shortening of the cable will affect the performance of the
transducer. For further information, please contact Autohelm or
an authorised Autohelm agent.

the following modification must be carried out to the transducer leads.
1. Using a pair of wire cutters, remove the moulded plug from the end
of cable.
2. Strip the outer cable back 38mm (1.5in)
3. Using a pair of cable strippers, remove 10mm (3/8in) of insulation
from each wire.

Chapter 4: Maintenance
4.1 Instrument
Atmospheric conditions may cause condensation to appear on the
instrument window. This will not harm the instrument and can be cleared
by increasing the illumination setting to level 3.
Chemical and abrasive materials must not be used to clean the ST30
Bidata instrument; if the instrument is dirty, clean with a soft, damp cloth.
4.2 Transducers
4.3 Cabling
Refer to the Installation and Maintenance instructions supplied with the
transducers.
Examine cables for chafing or damage to the outer shield and, where
necessary, replace and re-secure.

• display speed in knots
• operate with the depth alarms switched off
• operate in Master mode
These settings can be changed in calibration (section 6.1).
When the ST30 Bidata is switched on, depth information (upper display)
and speed information (lower display) is shown in the units set up in
calibration.

The ST30 Bidata is equipped with visual and audible shallow water and
deep water alarms.
Both of these alarms are set in calibration (see section 6.1).
Any button press will silence the 'Shallow' alarm. However, the 'Shallow'
indicator will continue to flash until the depth exceeds the alarm value.
The 'Deep' alarm sounds when the 'Deep' setting is crossed either when
going from shallow to deep or deep to shallow waters. Any button press
will silence the alarm.

Log calibration
The ST30 Bidata should not be used for navigational purposes until the
transducer paddlewheel has been calibrated to suit the characteristics of
the vessel.
This is a simple operation and is carried out as follows:
1. Choose two charted points that are approximately 1nm apart.
Point 1
Point 2
Approximately 1Nm
D699
2. Choosing a time when the tidal flow is at a minimum, go from point 1
to point 2 and record the ST30 Bidata trip distance.
3. Go from point 2 to point 1 and record the trip distance.
4. Add the two distances together and divide by two to obtain an
average distance.
5. Measure the distance between the two points on a chart.
6. The correction factor (CF) can now be calculated.

Repeater mode is set up as follows:
1. Press and hold and Depth for 5 seconds until the display shows U
