NEMA Connections TP22
Directly from the manufactures Manual. Spelling errors are theirs, Page 22 by the way.:
If a GPS or chartplotter is connected to the Tillerpilot, it can
extract the data necessary for Nav mode. Other functions such
as Steer To Wind may also be available, if NMEA0183-compatible
instruments are transmitting the correct NMEA sentences.
When connecting an external (“talker”) unit to the Tillerpilot,
two terminals are used – usually labelled DATA and COMMON
(or COM). These should be connected to the Tillerpilot’s
NMEA cable as follows :
NMEA Out Data/+ --> Tillerpilot Data (Red)
NMEA Out Common/- --> Tillerpilot Common (Blue)
NOTE Some third party equipment does not have a dedicated
COMMON connection. In this case, the DATA connection will
usually be labelled NMEA OUT, and the NMEA Common wire
from the Tillerpilot should be connected directly to 0v (terminal
2). If in any doubt, refer to the manufacturer, or Simrad’s
Product Support department for advice.
