Page 6: Introduction
IS12 Depth Sounder 1 GENERAL 1.1 Introduction The Simrad IS12 System is a flexible modular series of instru- ments that offer large, clear displays, easy to operate functions and robust, weatherproof construction. Whether as a stand alone instrument, or as part of a networked navigation system, the IS12 Depth Sounder will offer superb performance. -
Page 7: Is12 Network System
Instruction Manual 1.2 IS12 Network System The IS12 system is built around a high speed bus networking system that allows instruments to be easily interconnected and share data. All units are interconnected and powered using a standard sin- gle cable (Fig 1.2) - COMPASS Tx WIND Tx MEGA... -

IS12 Depth Sounder 2 OPERATION 2.1 Water Depth On power up, the current water depth is shown (Fig 2.1) - DEPTH DEPTH LIGHT SHALL DEEP INFO Fig 2.1 - Default Depth Display In this example, the depth is displayed in Metres. The arrow in the top line of the display indicates the trend (up or down). - Page 9 Instruction Manual Press the SHALL key to access the shallow alarm (Fig 2.2) - LIGHT SHALL DEEP INFO DEPTH SHALL LIGHT SHALL DEEP INFO Fig 2.2 - Shallow Alarm Function If the shallow alarm is OFF, pressing the (SHALL or DEEP) keys will switch on the alarm at the previously entered value (Min 0.6m/2ft, Max 100m/327ft).

IS12 Depth Sounder 2.2.2 Deep Alarm The deep alarm will sound if the water depth goes above a specified amount. Press the DEEP key to access the deep alarm (Fig 2.3) - LIGHT SHALL DEEP INFO DEPTH DEEP LIGHT SHALL DEEP INFO Fig 2.3 - Deep Alarm Function... -
Page 11: Info Key
Instruction Manual NOTE If no key is pressed within 5 seconds, the display will exit to the main screen and any changes will be ignored. If the alarm sounds, press DEEP to acknowledge and cancel. NOTE The deep alarm cannot be set lower than the shallow alarm, and the shallow alarm cannot be set higher than then deep alarm. -

IS12 Depth Sounder 2.4 Backlighting The backlighting illuminates the display and the keys, with five levels of brightness. To switch the backlighting on, press the LIGHT key. The dis- play will illuminate and the large digits will show the current lighting level (Fig 2.5) - LIGHT SHALL... -
Page 13: Remote Control / Alarm Option
Instruction Manual 2.5 Remote Control / Alarm Option The optional remote control allows all functions of each instru- ment to be remotely controlled. Any alarms sounded are also repeated on this unit. See Section 3.7 regarding enabling and disabling remote control functionality for this instrument. As this unit is intended to control all instruments in the IS12 range, the keypad is a generic design. -

Page 16: Damping
IS12 Depth Sounder 3.2 Damping The Damping function adjusts the update rate of the display. A damping level of 0 (minimum) will cause the display to update rapidly, while a damping level of 4 (maximum) will result in a more stable display, but one that is less frequently updated. Enter calibration mode, press once (the display will show DAMP CAL) and press... -
Page 17: Offset
Instruction Manual 3.3 Offset As a default, the Depth Sounder displays the water depth between the transducer and the sea bed. However, for boats such as sailing yachts with a keel, it is more useful for the display to show the available water below the keel, which is sometimes as much as 2m below the transducer. -
Page 18: Keel Offset
IS12 Depth Sounder To enter the offset, enter calibration mode then press twice (the display will show OFFST CAL) and press The current offset will be displayed - default value 0.0 (Fig 3.5) - DEPTH OFFST LIGHT SHALL DEEP INFO Fig 3.5 - Entering Offset 3.3.1 Keel Offset Since entering a keel offset is reducing the displayed depth, this... -
Page 19: Waterline Offset
Instruction Manual 3.3.2 Waterline Offset A waterline offset increases the displayed depth, so this is entered using the key - this adjusts the offset in 0.1m /0.1ft increments. The display will show “W’LN” (Fig 3.7) - W’LN LIGHT SHALL DEEP INFO Fig 3.7 - Entering Waterline Offset To set the selected waterline offset, press... -

IS12 Depth Sounder 3.5 Local & Network Backlighting The backlighting can be set so that any changes made are duplicated across the system (Network), or so that any changes are limited to this specific instrument only (Local). NOTE The IS12 instruments are set to Networked lighting as default. Enter calibration mode, press four times (the display will show LIGHT on the top line) and press... -

Instruction Manual 3.6 Shop Mode This is a simulation mode for in-store demonstration - do not use. 3.7 Disable Remote Control On some installations which includes the IS12 Remote Control, it may be more convenient to limit remote control access to only some instruments on the network - for example on a fly- bridge power boat with a set of instruments on both steering stations, it would not be desirable to be able to control the... -
Page 22: Installation
IS12 Depth Sounder 4 INSTALLATION 4.1 Instrument Head Installation All IS12 instrument heads are a standard 110 x 110mm (4.3 x 4.3 in) size, and can be mounted either from the front or the rear. 4.1.1 Front Mounting Fig 4.1 - Front Mounting 35mm (1.4 in) Front mounting (Fig 4.1) is the standard method of fitting and minimum... - Page 23 Instruction Manual The instrument is 110mm (4.33 in) square, but a distance of at least 6mm (0.25 in) should be allowed between adjacent units for the protective instrument cover supplied. NOTE Long term exposure to direct sunlight can damage the liquid crystal display if left unprotected when not in use - always use the instrument cover supplied.

Page 24: Rear Mounting
IS12 Depth Sounder 4.1.2 Rear Mounting When the instrument is rear mounted, only the display can be seen - the main body of the instrument, including the keypad is hidden behind the panel. This is a more elegant method of installation, but does require precise cutting of the apertures into the bulkhead or dashboard. -
Page 25: Transducer Installation
Instruction Manual 4.2 Transducer Installation The IS12 Depth Sounder is supplied with a 50mm (2in) diame- ter plastic depth sensor, or transducer. WARNING Plastic transducers are suitable for GRP, ferrous, ferrocement or wooden ply hulled boats. They are not suitable for boats with a solid, planked wooden hull as swelling can damage the trans- ducers. -
Page 26: Cutting And Sealing The Hole
IS12 Depth Sounder NOTE For the Depth Sounder to be accurate, the transducer must be as near vertical as possible. If the hull is angled in the selected position, it may be necessary to use a fairing block cut to the Fairing block correct angle so that the transducer is vertical when fitted (Fig 4.8). -
Page 27: Installing The Transducer
Instruction Manual Apply a coating of fibreglass resin to the inside edge of the hole, making sure all the raw edges are thoroughly sealed. This will prevent water seeping into the hull layers causing osmosis or delamination. 4.2.3 Installing the Depth Transducer Remove the large plastic nut from the transducer and uncoil the cable. -
Page 28: Electrical Installation
IS12 Depth Sounder 4.3 Electrical Installation IS12 instruments are ‘daisy chained’ together, with each instru- ment linking to the previous one by a single cable carrying power and data (Fig 4.11). The cable plugs into either of the two circular network ports on the rear of the instrument. Fig 4.11 - IS12 “Daisychain”... -

Page 30: Appendix
IS12 Depth Sounder 5 APPENDIX 5.1 Notes on Turbulence & Signal Acquisition Normally the depth displayed will be extremely accurate, how- ever there are certain circumstances where the accuracy of the signal can be adversely affected. If the boat is crossing the wake of a large vessel, the turbulence caused by the vessel’s passage will create air bubbles which could interfere with the depth sounder signal (Fig 5.1). -
