1. FOREWORD
Thank you for purchasing the WindObserver 65 manufactured by Gill Instruments Ltd.
The unit has no customer serviceable parts and requires no calibration or maintenance.
To achieve optimum performance we recommend that you read the whole of this manual
before proceeding with use. Do NOT remove black “rubber” transducer caps.
Gill products are in continuous development and therefore specifications may be subject to
change and design improvements without prior notice.
The information contained in this manual remains the property of Gill Instruments and
should not be copied or reproduced for commercial gain.
2. INTRODUCTION
The Gill WindObserver 65 wind sensor is a very robust unit with no moving parts,
outputting wind speed and direction. The units of wind speed, output rate and formats are
all user selectable.
The WindObserver 65 is available with or without de-icing heating (recommended if icing
is likely), and with or without analogue outputs.
The WindObserver 65 can be used in conjunction with a PC, data logger or other device,
provided it is compatible with the RS422 output or the analogue outputs. Multiple units
can be networked if required.
Alternatively, the WindObserver 65 is designed to connect directly to the Gill
WindDisplay unit to provide a complete wind speed direction system.
The output message format can be configured in Polar, UV (2-axis), NMEA (0183
Version 3), Tunnel formats, and as either a Continuous output or Polled (requested by host
system), detailed in full in Section 8 Message Formats & Options.
3. FAST TRACK SET-UP
If you are in a hurry to try out the WindObserver 65, are familiar with Gill equipment, and
coupling to a PC using RS422, go to the following sections:
Section 6 Installation
Section 7 Message Formats & Options
Section 8 Configuring
After you have successfully set up the WindObserver 65, we strongly advise that you then
go back and read the rest of the manual to ensure that you get the best results from the
WindObserver 65.

5.3. Installation requirements
Host system - One of the following:
PC with an internal or external interface compatible with the RS422 output from
the WindObserver 65.
Gill WindDisplay.
Other equipment with I/O compatibility to the WindObserver 65 option selected.
For example if the unit has Analogue outputs, a Data Logger, Chart Recorder, or PC
fitted with an ADC card.
Networking - Multiple WindObserver 65 units can be networked
Software - One of the following:
Gill Wind Software used as a Terminal program only (Wizard and Sync Comms
not applicable). Wind will run on PC’s up to and including Windows 10 and can be
downloaded free from:- http://www.gillinstruments.com/main/software.html
HyperTerminal (supplied with Windows™ 9x to XP).
Other Terminal Emulation software packages
Cable and Junctions Box
To connect between the WindObserver 65 and the host system. The unit is supplied with a
base mounted connector system or flying cable options (requiring a mast mounted
junction box (not provided)) for onward connection.
If using a flying cable option it must be retained with a cable tie within 150mm of the base
of the anemometer.
Mounting Bracket
The WindObserver 65 can be supplied with a short or long base mount to use with a
mounting bracket (not provided). The WindObserver 65 can be attached to the bracket via
the four tapped holes in the base mount fitted to the unit. The gasket supplied can be fitted
between the sensor and its mounting bracket when it is important to minimise the effects
of corrosion should two dissimilar metals be used.
In the event that the mounting bracket supplied by the customer is not flat or does not
form complete support for the anemometer base; the customer must fit a mounting ring as
shown in Figure 2.
Mounting Pole
The WindObserver 65 can be supplied with a pole mount that provides the option to attach
to a pole with or without a thread (pole not provided). The WindObserver 65 can be
retained to the pole via the three tapped holes in the pole mount fitted to the unit.

diameter of 7.9 to 12.6mm).
Prepare Cable (e.g. Gill Part 026-026643).
Trim back the cable outer and twisted pair screen sleeves 40mm (see diagram below).
Trim back the screen drain wires to a length of 24mm.
Strip back the connection wires by 7.1mm and tin solder.
Solder the wires to the bucket contacts (will take 14awg to 26awg wire).
Unused wires should be cut back and insulated.
Prepare Connector Head (Gill Part 020-04464).
Remove the connector thread protector and place the O-ring (part 7) into the groove of the
connector head (020-04464).

Assemble Connector to the Cable.
Referring to Page 9 push connector contacts through the red connector head seal into the
appropriate location, when in place there should be a click as the contact locks into
position.
Once contacts are in position pass part 6 up the cable and into position as shown below.
Note: if a connector pin needs removing use Cannon Extraction Tool,
Manufacturer’s Part 192922-1450.
Fold and spread screen wires over part 6 and then push up part 5 as shown to clamp screen
wires between Parts 5 and 6.
Now screw in part 4 and torque up to a value of 10Nm.
Pass parts 3 and 2, the cable seal and cable grip from the connector kit, along the cable to
the housing.
Now screw in item 1, the clamp nut, over parts 2 and 3 and onto the housing and torque up
to a value of 10Nm.
