3 ADVANCED FEATURES

The TP22 and TP32 Tillerpilots contain many advanced featur-

es, including the ability to accept course data from a variety of

sources other than the internal fluxgate compass. Such sources

include SimNet- and NMEA-compatible navigational receivers

(GPS/chartplotters, etc.), windvanes, and compass heading

transducers.

3.1 Nav mode

The TP22 and TP32 Tillerpilots can interface directly with

compatible Simrad chartplotters via the SimNet high-speed data

bus. They also have an inbuilt NMEA interface, which allows

connection to NMEA0183-compatible GPS and chartplotters.

Once interfaced with a GPS or chartplotter, the Tillerpilot can

steer using data from this source in addition to the internal

compass, allowing it to steer to a waypoint with great accuracy.

To activate Nav mode, the unit must be in Auto mode (press

STBY/AUTO). Simply activate a waypoint or route program-

med into the GPS/chartplotter and press the NAV key. The LED

next to the NAV key will light and the Tillerpilot will steer to

the first waypoint using Cross Track Error and Bearing To

Waypoint information from the navigational receiver to main-

tain an accurate course (Fig 3.1).

On arrival at the target waypoint an intermittent alarm will

sound. As a safety feature, to avoid an unexpected course

change, the next waypoint will not be automatically loaded

until the NAV key is pressed. When the vessel reaches the final

waypoint, the Tillerpilot will continue its current course under

Compass (Auto) mode.

Note Some of the standard key stroke functions may have a different

effect in Nav mode than in Compass mode (please refer to sec-

tions 2.3 and 2.4.3).

3.2 Steer To Wind

The TP22 and TP32 Tillerpilots can sail to the apparent wind

angle rather than a compass course using wind data via NMEA

interfaces or SimNet. Due to the faster data rate, the use of a

SimNet windvane such as the Simrad IS12 Wind is recommend-

ed – priority will be given to SimNet Wind data over NMEA

Wind data received by the Tillerpilot.
