4.2 Instrument Software Information
V1R1: Beta version, not used in ordinary production.
V1R2: First production version
V1R3: Upgraded version with added features.
• Trip log replaces sea temperature on first screen of IS15
Combi.
• In Locked Course mode the LCD on IS15 Compass has been
changed to show deviation in degrees from locked course.
• Improved log calibration procedure. Possible to set Log
reading as percent (%) of default value. Log calibration can
be set to same value on identical boats.
• Boat speed always reads 0.0 at zero speed. (V1R2 may show
- - - at turn on and a ‘residual’ speed value when slowing
down to zero speed).
• Improved boat speed and wind speed damping.
• Improved damping of heading displays.
• Depth transducer remains OFF at turn on if it was set to OFF
while the system was running.
• Test screens added to Installation Menu to simplify trouble
shooting.
• Roblink can be turned off and thus eliminate a possible
interference when a single instrument is connected as NMEA
repeater.
• ‘Communication reset’ added. Saves all settings in the event
an anomaly in the system functions calls for a reset.
V1R4: Substitutes V1R3 that contains a bug. V1R3 should not be
used.
V1R5: More installation features added.
• Manual setting (In/Out) of NMEA port added.
• Wind offset also applies when wind data is from an external
NMEA source.
Note ! V1R5 is backward compatible with V1R2 and V1R4. However,
anomalies may be observed if attention is not being paid to the NMEA
interface. In systems with mixed software, never interface NMEA
‘talkers’ to heads with V1R2 software.
