Chapter 1: Operation

1.1 Introduction
The ST30 Round Bidata instrument is designed for the powerboat market, and displays speed and depth information simultaneously on a split LCD. The Bidata can also display trip and log distances, sound a user-defined shallow alarm, and function as a repeater. The instrument can be surface or flush mounted and fits the standard 85.7 mm (3 3/8 inch) diameter facia apertures, common on many sports boats. The Bidata uses an easy-to-install transom mount transducer (Biducer) combining both speed and depth elements in a single housing. If the Bidata is used in conjunction with a SeaTalk autopilot, the speed input provided by the instrument enhances the pilot's steering performance.
The operating procedures are presented as a combination of flow charts and text. Unless otherwise stated, the illustrated key presses are momentary. The Bidata can display depth and speed information in metric and imperial units. These are set during basic calibration (see Chapter 4, Calibration).

075_4c01.p65

1.2 Depth key functions
The following flow chart shows the depth key functions.

WATER DEPTH

SHALLOW ALARM

OFFSET

D1763-2

Water depth

Depth is displayed in feet (0 to 400 ft) or metres (0 to 120 m).

Shallow alarm

The shallow alarm displays the depth (feet or metres) at which point audible and visual alarms will be triggered. These alarms can be silenced by pressing the speed or depth key.

Adjusting shallow depth

1. From the shallow depth alarm display, press depth and speed together momentarily to display CAL. 2. Press depth and speed together again momentarily to enter edit mode (+ and - displayed). 3. Press depth to increase and speed to reduce the displayed value. 4. Press and hold depth and speed together for 2 seconds, to exit edit mode and save the new value.

Silencing the shallow alarms
Press speed or depth to silence the audible alarm for a period of two minutes. If, after 2 minutes, the water depth is still below the alarm setting, the alarm will be activated again. Note: When the audible alarm is silenced the alarm icon continues to flash.
Turning shallow alarm ON and OFF
1. Ensure the shallow alarm screen is displayed. 2. Press depth and speed together momentarily to enter CAL mode. 3. Press depth to switch the alarm ON or OFF. 4. Press depth and speed together for 2 seconds to exit CAL mode.

Offset

This is the distance (feet or metres) from the Biducer to the bottom of the hull or to the waterline, which can be a positive (+) or negative (-) value.

Default display

The depth display will always default back to water depth 8 seconds after the last key press.

Loss of signal

If there are no depth echoes for 10 seconds, the feet/metres legend flashes and the last recorded depth is displayed until a new echo is received.

1.3 Speed key functions

The following flow chart shows the speed key functions.

D1764-2

The speed display can be either knots (Kts), miles per hour (Mph), or kilometres per hour (Kph).

Trip distance

Trip is the distance covered between power on and power off. This can be nautical miles (NM), kilometres (KM), or statute miles (SM).

Resetting Trip Distance

Press and hold the speed key until the trip distance is zeroed - distance flashes after 1 second and during the resetting process.

Ships log

When this value exceeds 999 NM, SM, or KM, the Bidata displays the log as thousands (th) and, after 3 seconds, hundreds, tens, and units. For example, 1525 nm would be displayed as 1th then 525.

1.4 LCD illumination

1 second High (L3)

Medium (L2)

Low (L1)

OFF (L0)

D1765-2
The Bidata has four illumination settings, off, low (L1), medium (L2), and high (L3). The Bidata automatically returns to normal operation 5 seconds after the last key press. If the shallow depth alarm is activated the illumination display is ignored.
Chapter 2: Maintenance and Faultfinding
Chapter 2: Maintenance and Fault Finding

2.1 Maintenance

Servicing and safety
Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product. Some products generate high voltages, so never handle the cables/ connectors when power is being supplied to the equipment. When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC). Always report any EMC-related problem to your nearest Raymarine dealer. We use such information to improve our quality standards. In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.

Cleaning the instrument

Periodically clean the instrument should be cleaned with a soft, damp cloth. Do NOT use chemical or abrasive materials.

Condensation

Certain atmospheric conditions may cause a small amount of condensation to form on the instrument window. This will not harm the instrument and will clear after the instrument has been switched on for a short period.

075_4c02.p65

Cables
Periodically examine the SeaTalk, Biducer, and power cables for evidence of damage to the outer shield, and if necessary, replace with genuine Raymarine cables.

2.2 Fault finding

If you appear to have a problem with your Bidata unit, please refer to this table before contacting your Raymarine Dealer. Fault

Log calibration has not been carried out (see Chapter 4). Calibration is set to off (see Chapter 4). Poor Biducer cable connection or cable damaged.

Chapter 3: Installation

3.1 Introduction
Please read this chapter thoroughly before attempting to install the instrument and transducer. Always use genuine Raymarine cables. The use of unapproved/inferior cables, for which Raymarine cannot be held liable, could affect the performance of the Bidata and other instruments on the SeaTalk bus. The Bidata may be flush mounted by installing the instrument from behind the instrument panel. The display bezel must not be assembled to the instrument if the Bidata is to be flush mounted.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. The guidelines given here describe the conditions for optimum EMC performance, but it is recognised that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: Raymarine equipment and cables connected to it are: At least 1 m (3 ft) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2 m (7 ft). More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.

075_4c03.p65

The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.

Suppression ferrites

The following illustration shows typical cable suppression ferrites fitted to Raymarine equipment. Always use the ferrites supplied by Raymarine.

D3548-2

Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close to the Raymarine unit.
3.2 Installing the instrument
When selecting a location for the Bidata instrument, ensure that: It is at least 230 mm (9 in) from a compass It is at least 500 mm (20 in) from radio receiving equipment There is sufficient clearance behind the bulkhead to house the rear of the instrument, fixing studs, C bracket, and SeaTalk cables.

84.4 mm (3.32 in)

17 mm (0.67 in) 89.1 mm (3.5 in) 94.15 mm (3.7 in) 37.5 mm (1.47 in) 54.5 mm (2.15 in)

D1598-2

CAUTION
Where it is necessary to cut holes (e.g. for cable routing and instrument mounting), ensure that these will not cause a hazard by weakening critical parts of the vessels structure. If in doubt, seek advice from a reputable boat builder. 1. If appropriate, use the template provided near the back of this book to mark the intended location of the Bidata instrument. 2. Use a tank cutter to machine an 85 mm (3 3/8 in) clearance hole for the instrument. Note: If you do not wish to use a tank cutter, the hole can be machined using a hole saw and a file.

D1599-2

2. Remove any burrs from the aperture.

3.3 Connecting the power supply direct
Ensure that the power supply is protected by a 5 A fuse or circuit breaker. 1. Plug the 2 m (6 ft) power cable into one of the SeaTalk ports. 2. Connect the red wire to 12 V (+) and the screen to 0 V (-). Protect the circuit with a 5 A fuse/circuit breaker.

D1602-2

3.4 Power via SeaTalk
Ensure that the power supply is protected by a 5 A fuse or circuit breaker. If the Bidata is to be used with other SeaTalk instruments, the power supply is passed from instrument to instrument via the daisy loom cable as shown.
3.5 Adding an independent lighting switch
When the Bidata is part of a SeaTalk system the lighting is controlled from the keypad or from another SeaTalk instrument on the bus. If you have an independent lighting switch, this can be connected to the terminal so that the Bidata lighting can be switched with your existing equipment.

Caution: Plastic through hull transducers must not be used on vessels with wooden hulls.
Note: The ST30 Speed transducers are fitted with standard paddlewheels designed for speeds up to 32 knots. For vessels that will exceed this speed, please refer to section 2.3 which contains instructions on how to fit the high speed paddlewheel (supplied).
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. 2. 3. 4. 5. Remove the retaining rings (1) and pin (6) from the speed transducer (3). Withdraw the speed transducer (3) from the through hull fitting (4). If replacing a worn paddlewheel and if the vessel is still in the water, replace the speed transducer (3) with the plug (5). Remove the pin (6) that retains the paddlewheel (7) in the speed transducer (3). This is a simple press fit into the transducer housing. 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.
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.
Siting of depth transducer (Standard through hull)

The depth transducer must be vertical to within 10, forward, aft and athwart ships.
