Warning: Due to the limitations of NMEA0183, it is
recommended that only one talker is transmitting to the
Tillerpilot at any one time – i.e. instruments or GPS/chartplotter,
not both simultaneously! If more than one unit needs to be
interfaced to the Tillerpilot, these should be connected to the
NMEA cable via a changeover switch.
Because of the vast number of different manufacturers and models
of navigational equipment, Simrad cannot guarantee correct
operation and installation of third party equipment. Therefore,
before connecting any equipment to the Tillerpilot it is important
that the unit’s manual is referred to with regard to interfacing via
NMEA.
Electronic interference suppression
The Tillerpilot has been designed to minimize the effects of
interference generated by the engine alternator. However,
precautions should still be taken by routing the cables away from
the engine compartment. Do not run the cables down trunking
carrying high current or radio antenna cables.
Engines with spark ignition, also some refrigerators, should be fitted
with suppressors. Your local agent should be able to advise on this
and supply suppression kits where necessary.
Auto compass calibration
Once the Tillerpilot is installed, it is necessary to calibrate the internal
compass to compensate for deviation caused by any metallic or
magnetic objects surrounding it on the vessel.
With the vessel motoring slowly (2–3 knots) in calm conditions and
the Tillerpilot in Standby mode, press the Starboard (
) key a
number of times to induce a slow, clockwise rotation of the vessel.
Then press and hold the TACK key, followed by the Port ( ) and
Starboard ( ) keys simultaneously.
The Port and Starboard LEDs will both light. Allow the vessel to
turn through a minimum of 11/4 turns (450º) in approximately two
minutes, during which time the fluxgate compass will automatically
calibrate itself.
