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 Fe et Kn ots DE PT H D RE SP EE D SE T SP EE SP DI Y LA BID AT A TM D681 6 ST30 Bidata Operation and Installation Handbook Chapter 1: Control Head Installation 7 Chapter 1: Control Head Installation 42mm (1.65in) 24mm (1.00in) 56mm (2.20in) TM SPEED BIDATA 110mm (4.33in) 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. 88mm (3.46in) D682 DEPTH 8 ST30 Bidata Operation and Installation Handbook 1.2 Mounting procedure 3 6 5 2 4 1 D682a 1 Instrument 2 Fixing studs 3 Thumb nuts 4 Sealing gasket 5 Depth transducer cable 6 Speed transducer cable 1. 2. Make sure the surface to which the instrument (1) is to be mounted is smooth and flat. 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. 4. 5. 6. 7. Drill two 5mm (0.2in) diameter holes for the fixing studs (2). Using a 60mm (2 3/8in) diameter cutter, drill a location hole for the instrument connector boss. Connect the power supply and transducer cables to the back of the instrument (1) (see relevant installation sections). Screw the two fixing studs (2) into the back cover. Install the instrument (1) and secure with the thumb nuts (3) provided. Chapter 1: Control Head Installation 9 1.3 Power supply (Stand-alone operation) Caution: The ST30 Bidata must be connected to a 12V supply only. + + SEATALK DE PT D EE + 5A + 12v Supply ­ For stand-alone operation, use the standard 1m cable supplied. 1. Connect the moulded power plug to either 'SeaTalk' connection on the rear of the instrument. Run the free end back to the vessel's distribution panel. Cut the cable to length and connect the red wire to 12V and the screen to 0V. Protect the circuit with a 5A fuse/circuit breaker. 2. 1.4 Power supply (SeaTalk system) The ST30 Bidata can be connected to an existing SeaTalk system using a Standard SeaTalk Extension or Interface Cable. Autohelm Autohelm Power Extension Cable D628 H SP + Red Screen D683 Autohelm 10 ST30 Bidata Operation and Installation Handbook 1.5 Connection to adjacent ST30 Instruments 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. Chapter 2: Transducer Installation 11 Chapter 2: Transducer Installation 2.1 Connection to instrument The depth and speed transducers are supplied with 10m (32.5ft) of cable. These cables are fitted with female spade connectors that plug directly into the back of the ST30 Bidata instrument. + + SEATALK DE PT H + Speed 2.2 Transducer type The ST30 Bidata system is supplied (as standard) with plastic through hull transducers. These are suitable for use with Glass Reinforced Plastic (GRP), Steel and Aluminium hulls. Alternative transducers are available for wooden hull and transom mount installations.

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). Chapter 2: Transducer Installation 13 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). 3 6 7 5 8 2 1 4 D587a 14 ST30 Bidata Operation and Installation Handbook 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 15 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.
