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 31. Setting the damping factors The damping factors determine how fast the display will respond to changes. The higher damping factor the more stable display reading on the instrument.
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.
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). The Anchor alarm should be turned Off when the boat is not at anchor! Alarm Range Change per step Deep Off - 650 ft 1.6-5: 5-10: 10-50: 50-100: 100–500: 500–650: 0.1 0.5 1 5 10 50 ft ft ft ft ft ft Off Shallow Off – 320 ft 1.
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. Automatic source update The Auto select option will look for all sources connected to the instrument system.
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.
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. Refer to Backlighting, page 12.
Language selection The language is usually selected when the instrument is turned on for the first time. Refer to First time startup, 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) -- Français (French) -- Italiano (Italian) -- Nederlands (Dutch) -- Norsk (Norwegian) -- Svenska (Swedish) The language names are listed alphabetically in their own language.
Changing the units of measure Parameter Options Default value Boat speed - kn - km/h - mph kn Distance - nm - mi - km nm Depth -m - ft ft Temperature - °C - °F °F Changing the SimNet group setup The SimNet groups are normally configured during installation, but may be changed at any time.
SimNet group function The SimNet group function provides global control of groups of units. This option is used on larger vessels where many units are connected via the SimNet network. By assigning several units to the same group, a function change or update on one unit will have the same effect on the rest of the group members. The table below shows available SimNet groups.

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. Mechanical installation Panel mounting The mounting surface must be flat and even to within 0.5 mm.
Bracket mounting An optional bracket is available for the IS20. The illustration below shows the mounting details for the bracket.
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. The SimNet accessory program contains the necessary items to make a successful installation. Refer to SimNet cables and accessories, page 58. SimNet cables A SimNet unit has one or two yellow SimNet connectors.
The connectors are weather proof according to IP66, when properly installed. All unused SimNet connectors must be fitted with the plastic cap to protect them against dirt and moisture.

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: 1 Product name, serial number, software version, release date 2 Language selection 3 Automatic data source selection Press the Menu/Enter key when the start-up procedure is completed. This will change the display to the default Speed/Depth/Temperature page.
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.
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. 1 Bring the boat up to cruising speed (above 5 knots) 2 Select Calibrate w/SOG and press the Menu/ Enter key to start the calibration 3 When the calibration is completed the SPD Correction factor is set to 1.
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 symbol in front of the depth reading will change to indicate that the depth is measured from: the keel or the water line Range Change per step Default value Units -10 - +10 0.1 0.
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. For additional information about SimNet groups, refer to SimNet group function, page 31 and onwards.
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. Make sure that all open SimNet connectors are fitted with a protection cap (part no. 24006355).
System data The System data screen provides status information about the different NMEA messages used by the system. Resetting the instrument system The reset options will reset the instrument to default settings.
Displaying instrument information By selecting the About IS20 menu item, an information window will display instrument model, software version number (1.0.), software release (02) and date of release.
