DATAMARINE WIND INSTRUMENTS
Datamarine uses an AC 3 phase synchro to
transmit wind angle information from the
masthead unit.
You must order the WIND VANE SYNCHRO
CONVERTER (part number 93297) from
ComNav to tie into a Datamarine wind vane.
Information on wire colours and other hookup
information is included with the synchro
converter.
Additionally, the Compass Interface Circuit
Board in your autopilot will need to have some
jumpers moved to make it compatible with the
synchro converter. Instructions on how to do this
are included with the synchro converter, however,
we recommend it be done by your dealer.
OCKAM WIND INSTRUMENTS
Refer to the OCKAM manual to obtain the wire
colours for the S1, S2 and S3 wires from the
masthead unit as the colours vary with the brand
of masthead used.
Connect the S1, S2 and S3 leads from the
autopilot in parallel with the S1, S2 and S3 leads
from the masthead unit. The other wires in the
cable from the autopilot are not used, and should
be cut off to avoid the possibility of short circuits.
Turn on the wind instrument, place the autopilot
master select switch in the STANDBY position,
and press the WIND ON/SET key. If the reading
on the autopilot display is increasing when the
actual wind angle is decreasing, reverse any two
of the wires from the autopilot. Press and hold the
WIND ON/SET key and press either the up or
down ARROW key until the reading on the
autopilot display is the same as the actual wind
angle.
Alternately if you have the AUTOPILOT NMEA
DRIVER MODULE and the autopilot has 02.06
(01.15) software, you may use the NMEA 0183
connection described above.
DO NOT confuse this with the Model 045
NMEA-0183 DR DRIVER MODULE which
does not transmit wind angle information.
You may choose either True or Apparent wind
data using Switch S2 inside the module. The
interface will work with either Normal Fields or
Fixed Field Width.
SIGNET WIND INSTRUMENTS
The S1, S2 and S3 wires from the autopilot
should be hooked in parallel with the RED,
WHITE and GREEN wires from the masthead
unit. The other wires in the cable from the
autopilot are not used, and should be cut off to
avoid the possibility of short circuits.
Turn on the wind instrument, place the autopilot
master select switch in the STANDBY position,
and press the WIND ON/SET key.
If the reading on the autopilot display is
increasing when the actual wind angle is
decreasing, reverse any two of the wires from the
autopilot. Press and hold the WIND ON/SET
key and press either the up or down ARROW
key until the reading on the autopilot display is
the same as the actual wind angle.
