The
LX -360 provides both wind direction ( in
360° analog form) and wind speed ( in digital form)
information
in one compact, watertight, 4" aluminum
case. Provision has been made for additional
indicating units or a close hauled indicator to be
added either now or
at a later date.
Take a few minutes to read through
thi s short

General Description
The Model LX-360 apparent wind/wind speed indi-
cator
is an advanced design, wind instrument giving
a sailor
all the wind information needed on one,
compact instrum
ent. Wind direction information is
displayed
in analog (pointer) form on a front panel
meter covering a continuous,full 360°. Wind speed
information
is displayed digitally, in knots, on a two
digit liquid crystal display. The entire face
is lighted
for night operation.
The LX-360
is supplied with 80 feet of mast wir-
ing ,a mast step junction box, and all necessary mast-
head material. Cable length
is not critical and may be
lengthened or shortened as needed.
Int ernal, lower unit, adjustment (up to ± 180°) is
available in the LX-360 to compensate for any
mounting angle
of the masthead unit. This eliminates
the need for exact fore/aft positioning
of the wind
vane.
Provision has also been made for the use
of two
remote units (Model LX-360R or a wind expander
instrument Model
AWX) for the LX-360. A description
of these installlations will be found in the section
entitled "Repeaters
".

Op eration
After installation and alignment (if necessary, see
section entitled "Alignment") your LX-360
is totally
automatic
in operation. The only control is for OFF-
DAY-NIGHT lighting and
is located on the rear panel
(see figure 1
).
On the rear panel, one will note the following:
Off-Day-Night Switch -Used for control of the
instrument.
OFF denotes no power to the instru-
ment
or the masthead unit. DAY turns the LX-360
on for daylight viewing. NIGHT illuminates the
instrument for night operation. Power drain
is mini-
mal
in the day mode.
-Power -12V DC (0.1 ampere) connected with in-
line 1 amp fuse to ship's battery. Power connec-
tions are available for remotely mounted OFF-
DAY-NIGHT brightness control.
LX-360
REAR
PANEL VIEW
Input -7-pin terminal strip connector for mast-
head wiring. This provides
all connections neces-
sary for wind speed and wind direction sensors.
When the instrument
is operating, there may be
Slight hum heard from the LX-360. This is normal
and should
be expected.

As one sails with the LX-360, th e instrument will
give continuous apparent wind angle readings with
relation to the lubber (fore and aft)
lin e of the boat.
The meter
(b eing full 360°) will pass through 0°
when tacking and through 180° when jibing. The
di~
ital wind speed display will indicate apparent wind
speed under
all operating circumstances.
The front panel of your LX-360
is scratch resis-
tant and the housing has an anodized finish.
You
may clean and wipe the face panel as you would
other parts
of the boat, using a mild soap and water
as necessary (highly abrasive cleane
rs are not
recommended). Do not, however, spray the rear
panel connections.
The liquid crystal display
of your new instrument
has been thoroughly tested and manufactured for
the marine environment. Under extreme tempera-
tures, however, the display
will become unreadable.
Extreme heat (above 175°
F) will tend to black out
the display, (display will become operational again
when temperature
is reduced) while extreme cold
(below 10°
F) will slow the digits to a point where they
will "freeze" on one number. This is normal and
should
be expected by the new owner. As noted in
the specifications, storage temperatures are higher
and lower than the above mentioned operation
temperatures, h·owever, temperature extremes
beyond these specified can destroy the liquid crystal
display and void the warranty.
In normal operation a small amount of heat will
be generated by the night lighting of the LX-360. This
will not harm the instrument and may
be desirable
even
in daylight while operating in colder
temperatures.
Your LX-360 has a front panel cover to help pro-
tect the face and the liquid crystal display when the
instrument
is not in use. This protective cover should
be used whenever your boat
is left for a period of
1e or when conditions warrant further in strument
rotection.
Installation
The LX-360 is intended to be permanently installed
in a cockpit bulkhead or instrument console. It will be
watertight and theft proof when properly installed.
Select a location
on a flat surface which is easily
seen
by the helmsman while in his normal steering
position.
Saw a 41
/8" diameter hole
in the panel for clear-
ance
of the instrument's body. Remove th e clamp
ring from the instrument. Apply a small amount of
waterproof bedding compound around
th e outer
edge
of the hole and press the instrument into place.
Make sure the 0° and 180° markings line
up
vertically.
Next, place the clamp ring
on the LX-360's
body, from the inside, and press against the bulk-
head
or console. Tighten the set screws to the
instrument, then the set screws against the mounting
panel,to hold the LX-360
in place (see figure 2).
Service of the instrument may be accomplished
by removing the "spring retaining ring" from the rear
panel and sliding the electronics package out
ugh the back
of the instrument. This eliminates
need to break the instrument's waterproof seal.

P ow er Connection
The 12 volt d.c. power for the LX-360 should be
connected using the power cord provided. The RE
lead goes from the +12 terminal to the ship's POS
power and the BLACK lead is connected from the
"NEG" terminal to the ship's NEG (- ) power. The LX-
360
is protected against polarity reversal. The
instrument's power cord
is fused with a 3AG-1 , 1
ampere fuse. Do not use any other size fuse. (See
wiring diagram
in figure 3.) T he "lamp" terminal
(which
is jumped to the 12 v terminal) is only used
when the accessory remote lighting control (A-180)
is connected.

Mounting the Masthead
Bracket a
nd Wiring
Prior to stepping the mast, lay out the cable and
masthead mounting bracket to determine the length
of the cable needed. Cable length should allow for
running to a convenient, dry location for the junction

box once the mast
is stepped. Once the necessary
cable length
is determined (to run to the mast step
junction box),
it should be cut and fed down the mast
from the masthead.
The bracket should be mounted so the grom-
meted hole and the rear alignment
pin line up with
the fore/aft axis
of the boat,the grommeted hole
being forward. A mounting template
is provided in the
back
of this manual. The bracket may be moved
slightly within the confines
of the adjustment slot for
final positioning.
The LX-360's lower unit may be field adjusted to
compensate for any masthead mounting angle. The
mounting bracket should be mounted horizontally
(shim as needed) as close to the top of the mast as
possibl
e. An "L" shaped adapter bracket is provided
for mounting
on the side of a mast if this is needed.
The remaining section
of cable should be
installed from the final location of the LX-360 and run
to the estimated location of the wiring junction
box.
Cable length is not critical and may be added to or
trimmed as necessary.
If needed on a particular installation, Datamarine
can provide a cable connector to use
in place of the
junction
box. Wire color and pin connections are
provided below. A 120' cable (Model WX-177)
is also
available.

CABLE TO INSTRUMENT
Mount the junction box in a dry, convenient
location and, once the mast
is stepped, run both cut
ends
of the wire into it. Install the spade lugs pro-
vided and connect to the terminal strip (red to
red,
white to white, etc.) as shown on figure 4.
This completes the wiring required to connect
the masthead unit to the LX-360.
To complete the
installation,connect the cable from the junction box
to the LX-360 as shown in figure 3.
TE: Make sure
a// wires (including the shield) are
l,Dnnected
in the Junction Box. This will assure
proper operation
of your LX-360.

Installation of Masthead Unit
The masthead boom (rotating cups and wind vane)
is designed to mount in the masthead mounting
bracket (see previous section). The boom should be
slid into the grommeted hole until
it seats firmly over
the rear alignment pin (see figure
5). At this point the
boom retaining pin should be inserted to its full
extent. Make sure the wind cups are
on the bottom
end of wind sensor housing when the boom
is
mounted.
The masthead cable connector should now be
plugged into the receptacle on the mounting bracket.
After mating the connector set, rotate the
lo cking ring
until
it seats to secure the connection. The cable is
designed to provide a drip loop, but this loop must
not interfere with any masthead hardware (spinnaker
halyards, blocks, etc).
The masthead installation is now complete and
ready for operation.

Instrument Alignment
With LX-360 turned on, one can adjust the lower
;.idicating unit to compensate for any misalignment
f the masthead sender.
A person at the top of the mast should first align
the wind vane by hand so
it points exactly forward;
this can also be done by securing the wind vane with
tape before the mast is stepped. After this is done,
locate the slotted shaft labeled POINTER ADJUST
in
the center of the LX-360 rear panel (see Figure 6).
Turn the shaft with a slotted screwdriver until the
pointer lines up at the zero mark. This completes the
alignment process. Be sure to remove any tape used
to secure the wind vane when alignment is
completed.
Repeaters, Wind Expanders
Provisions have been made for the use of an LX-
360R remote display or
AWX Wind Expander. Direc-
tional and speed accuracy will not be affected by this
addition, although the second unit's directional
alignment must be matched to the master at the time
of installation.
To use a repeater or wind expander with an LX-
360 system, mast wiring must be paralleled from the
mction box to the remote.
In addition, 12 volt power
""ires must also be connected to the repeater (see
figure
7).

Ma sthead Repairs
or R
ep lace ment
maged wind cups or direction vanes may be
simply replaced without the need of returning the
masthead assembly to Datamarine.
Both the wind cups and the wind vane may
be
removed by loosening the small set screw in the side
of each assembly and sliding the cups or vane off of
the shaft.
To reinstall a wind vane, the vane should be
slipped over the syncro shaft until
it bottoms. (See
figure
8). Care should be taken to install the new
vane
in the approximate position that the old one
came
off ;this will help at the time of realignment.
After installation of the new vane, the LX-360's direc-
tion syncro must be realigned (see section entitled
"Instrument Realignment"
).
To install a new wind cup assembly, line up the
set screw with the flat portion of the shaft and slide
the assembly
on the shaft until the shaft is flush with
the bottom of the wind cup hub. (See figure
8).
Tighten th e set screw securely. Please note: Indi-
vidual wind cups are not replaceable, the whole unit
must
be changed.
After changing the cups
or the vane, the mast-
head unit should be reinstalled as directed
in the
section entitled "Installation of Masthead
Unit "

Owners of S-200DL, S-1 OOKL, and LX-360 instru-
ments may remotely mount a power/night light
switch for control of the instruments when rear panel
access
is restricted (ie. pod mounts, etc.).
Datamarine's A-180 control panel/log
is idea ll y
suited for this application when the
S- 1 OOKL is
included
in the installation. The A-180 provides both
an ON-OFF switch with a night lighting brightness
control and a non-resettable
log.
A double pole -double throw switch may be
• }d for this remote control. A wiring diagram is pro-
ed below to aid in connecting a switch of this type.
The power switch
on the back of the instrument
must
be left in the "NIGHT' position when using a
remote switch. Also, the jumper between the "+12"
terminal and the "lamp" terminal must be removed to
us e a remote switch.
