Note ! IS11 is the new instrument system from Simrad. It
replaces the previous Dataline X system. Instructions in
this manual referring to IS11 will mainly apply also for
the previous Dataline X system.
The diagram is only showing the necessary connections to
provide NMEA input (speed, wind, navigation) to the AP11,
and NMEA heading output to the IS11 system. Other
connecting diagrams for the IS11 system are shown in the
separate IS11 manuals.
