Instruction Manual 1 GENERAL 1.1 Introduction The TP10, TP22, and TP32 Tillerpilots from Simrad are suitable for a wide variety of tiller-steered sailing yachts up to 12 m (39 ft) overall length. Combining highly sophisticated electronics with advanced soft- ware and a powerful mechanical drive, they are capable of pro- viding reliable and accurate steering performance under a variety of different conditions with minimal current consumption.
Tillerpilots TP10/TP22/TP32 1.2 The SimNet network system The SimNet system is built around a high-speed bus network- ing system, that allows the TP22 and TP32 to be easily inter- connected to Simrad instruments and navigation equipment. Units are interconnected and powered using a standard single cable (Fig 1.2).
Instruction Manual 2 OPERATION 2.1 General The keypad of the Tillerpilot has been designed to be as simple and intuitive to operate as possible. Using only five keys (see Fig 2.1), it is possible to perform precise course adjustments and navigational functions. TACK The unit powers up in Standby mode indicated by a flashing LED next to the STBY/AUTO key (Fig 2.1).
Tillerpilots TP10/TP22/TP32 2.3 Adjusting course In Autopilot mode, precise course adjustments can be easily made: TACK • press the Port ( ) or Starboard ( ) key once and a 1º course adjustment will be made in the specified direction. This is confirmed by a single beep and the Port or Starboard LED will STBY STBY...
Instruction Manual 2.4.3 Autotacking in Nav mode As the Tillerpilot will be steering directly to a waypoint, the autotack facility is disabled while in Nav mode. If it is necessary to perform an autotack, disengage Nav mode by pressing the NAV key then perform the autotack. WARNING Ensure that the boat is on the correct tack before re-engaging Nav mode.
Tillerpilots TP10/TP22/TP32 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.
Instruction Manual If no wind information is present, the Tillerpilot will not enter Note Steer To Wind mode. To select Steer To Wind mode, the unit must be in Auto mode TACK (press STBY/AUTO). Press and hold the Port ( ) and Star- board ( ) keys together until a double beep is heard (Fig 3.2).
Tillerpilots TP10/TP22/TP32 4 CONFIGURATION 4.1 Porthand mounting Although the Tillerpilot is factory preset for Starboard-side mounting, it is possible to reconfigure it for mounting on the Port-side of the cockpit to facilitate easy installation on most types of yacht (Fig 4.1). TACK TACK STBY...
Instruction Manual 4.3 Adjusting Gain The Tillerpilot will apply adjustments to the tiller, in order to compensate for heading variations, the amount of movement being proportional to the heading error detected by the compass unit. The amount of movement is set by the Gain (sometimes referred to as the rudder ratio).
Tillerpilots TP10/TP22/TP32 flashes of the Nav LED indicates that the Tillerpilot is set to Auto Seastate. • Use the Port ( ) and Starboard ( ) keys to adjust the Seastate setting between 0 and 9. Selecting 0 will switch the Tillerpilot to Auto Seastate.
Instruction Manual 5 INSTALLATION 5.1 Fitting the Tillerpilot The Tillerpilot is a very sophisticated piece of equipment and, therefore, in order for it to function to its full capabilities, it is essential that it is installed correctly. Please read this section thoroughly before attempting installation and use.

Tillerpilots TP10/TP22/TP32 Note If the dimensions given are not practical for the vessel to which the Tillerpilot is to be fitted, a range of fitting accessories are available to facilitate correct installation. (Please refer to sec- tion 6.4 for more details.) CAUTION The Tillerpilot houses an internal fluxgate compass and should therefore be mounted away from sources of magnet-...
Instruction Manual 5.2 Electrical installation 5.2.1 Installing the TP22 and TP32 The Tillerpilot operates from a 12 V DC supply. The waterproof plug fitted to the Tillerpilot is used to supply the power, SimNet and NMEA data. The bulkhead socket should be mounted in a convenient position, close to where the Tillerpilot is to be fitted, and wired as shown (Fig 5.5).
Tillerpilots TP10/TP22/TP32 5.2.2 Installing the TP10 The TP10 Tillerpilot operates from a 12 V DC supply and is connected to the supply by two wires (Fig 5.7). Although the cable is supplied with bare ends, it is recommended that a good quality waterproof plug and socket is fitted for maximum relia- bility.

Tillerpilots TP10/TP22/TP32 In the example above (Fig 5.9), there are two nav data sources (the CP44 Chartplotter and the NMEA GPS via the IS12 Mega instrument) and two external heading sources (the IS12 Com- pass and the RFC35R Rate Compass via the AP25 Autopilot). The Tillerpilot could be used as a backup pilot, while still retaining the RFC35R as the heading data source.
Instruction Manual 5.5 Interfacing via NMEA The inbuilt NMEA processor allows NMEA 0183-compatible equipment to be connected directly to the TP22 and TP32, with- out any need for a separate interface unit (Fig 5.12). Wind Speed GPS/Chartplotter SimNet Tillerpilot power Fig 5.12 - NMEA integration examples If a GPS or chartplotter is connected to the Tillerpilot, it can extract the data necessary for Nav mode.
Tillerpilots TP10/TP22/TP32 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.
Instruction Manual 6 APPENDIX 6.1 Advice on operation When used correctly, your Tillerpilot can maintain as good a course on most points of sail as a skilled helmsman, with the advantage that it never gets distracted. A human can start show- ing lapses of concentration after as little as 10 mins.
