  • Page 24: Changing The Default Settings

    4 Changing the default settings General The factory default settings may all be changed from the User setup command in the Main menu.  Updating the settings will affect all instruments in the SimNet group. Refer to SimNet group function, page Setting the damping factors The damping factors determine how fast the display will respond to changes.

  • Page 25: Alarm Setup

    Alarm setup The IS20 may be set up to sound an alarm if vessel or environmental parameters exceeds preferred values. The alarm monitoring is disabled by setting the value to Off. Boat speed alarm Used to give alarm if the boat speed goes beyond a selected value.
  • Page 26 Depth alarm The depth alarm can be set up for deep and shallow water limits. An anchor alarm can be activated to warn if the boat is drifting. The alarm will sound when during a 40 seconds time period there is a change in depth of 2-3 meters (6–10 ft).

  • Page 27: Updating The Data Sources

    Updating the data sources A data source can be a sensor or a device connected to SimNet, providing information and commands to other SimNet devices. The data sources are normally configured at first time turn on. It should only be necessary to update this data if a new source is added, if a source is missing (sensor failure), or if a source has been switched off/on.
  • Page 28 Manual source selection If more than one source is available for each item, the preferred source may be selected manually. As an example, the following illustrations show how the compass source is changed.  The position source provides Speed Over Ground (SOG). Select the preferred data source and confirm with the OK softkey.

  • Page 29: Changing The Display Settings

    Changing the display settings The display is controlled by two user profiles that can be individually adjusted. The profiles are Day profile and Night profile. The profiles can be optimized for readability under different light conditions, and you can quickly switch between the two using the Light key.

  • Page 30: Language Selection

    Language selection The language is usually selected when the instrument is turned on for the first time. Refer to First time start- up, page 47. It is, however, possible to change the language at any time. The following languages may be selected: Deutch (German) English (English) Español (Spanish)

  • Page 38: Installation

    6 Installation Location of the unit The IS20 should be mounted with special regard to the unit’s environmental protection, temperature range and cable length. Refer to page 59. Avoid mounting the control unit(s) where it is easily exposed to sunlight, as this may shorten the lifetime of the display.

  • Page 39: Bracket Mounting

    Bracket mounting An optional bracket is available for the IS20. The illustration below shows the mounting details for the bracket. Installation...

  • Page 40: Cable Connection

    Cable connection The IS20 Combi may be connected to SimNet network using SimNet cables. SimNet The SimNet cable system with very small plugs in both ends makes it easy to run the cables. Only 10 mm (3/8”) holes are required through panels and bulkheads.
  • Page 41 41, 42 and 43 SimNet must be properly terminated, i.e. unless it is a small system (see the figure on page 41) there must be terminations at each end of the Simrad backbone The SimNet network has to be terminated according to the number and type of products connected.

  • Page 45  Maximum total length of SimNet cables is 150 m (500 ft.) Drop cables must not exceed 6 m (19 ft) of length and the total length of drop cables must not exceed 60 m (200 ft). Equipment should not be daisy-chained in a drop cable.

  • Page 46: Demo Mode

    Demo mode The IS20 includes a demo mode, useful for demonstrations and on show. Active demo mode is indicated with flashing DEMO text in the upper right corner of the page. The demo indication will flash more frequently on the demo source than on units that are reading the demo values.

  • Page 48: Configuration

    7 Configuration First time start-up When the IS20 is powered on for the first time, the instrument will run through an automatic start-up sequence, presenting: Product name, serial number, software version, release date Language selection Automatic data source selection Press the Menu/Enter key when the start-up procedure is completed.

  • Page 49: Calibration

    Calibration After installation, certain functions in the system must be calibrated to adapt to the physical position and type of sensors installed. All calibration is initiated from the CALIBRATION sub menu. Boat speed The hull shape or the location of the speed sensor may cause incorrect speed readings, and calibration is required to ensure that correct speed and log readings are displayed.
  • Page 50 Calibrate by speed over ground With a GPS connected to the system, the speed may be automatically set identical to the speed over ground value. This adjustment should be made in calm sea with no effect from wind or tidal current. Bring the boat up to cruising speed (above 5 knots) Select Calibrate w/SOG and press the Menu/...
  • Page 51 Depth The default value for the depth offset is 0.0, which indicates the displayed depth from the transducer to the seabed (b). Refer to the illustration on the next page. The value should be increased or decreased, depending on whether the depth reading should be from the water line or from the keel, respectively: A negative offset equal to the vertical distance from the transducer to the keel will display the...

  • Page 53: Simnet Groups

    SimNet groups The SimNet group function is used to globally control parameter settings in groups of units. The function is used on larger vessels where several units are connected via the SimNet network. By assigning several units to the same group, a parameter update on one unit will have the same effect on the rest of the group members.

  • Page 54: Maintenance

    8 Maintenance General maintenance The IS20 instruments are “repair by replacement” units, and the operator is therefore required to perform only a very limited amount of preventive maintenance. If the unit requires any form of cleaning, use fresh water and a mild soap solution (not a detergent). It is important to avoid using chemical cleaners and hydrocarbons such as diesel, petrol etc.
