Page 4: Foreword
________________________________________________________________________________________________________________________ 1. FOREWORD Thank you for purchasing a WindMaster HS manufactured by Gill Instruments Ltd. The unit has no customer serviceable parts and require no calibration or maintenance. To achieve optimum performance we recommend that you read the whole of this manual before proceeding with use. -
Page 5: Principle Of Operation
Figure 1 Time of Flight details The WindMaster HS measures the times taken for an ultrasonic pulse of sound to travel from an upper transducer to the opposite lower transducer, and compares it with the time for a pulse to travel from lower to upper transducer. -
Page 6: Polar Definition
WindMaster HS 1951-PS-001. Issue 4 August 2021 ________________________________________________________________________________________________________________________ Figure 2 shows the direction and polarity of the U, V and W axes. Polar definition The wind speed in the UV plane, with direction in degrees from 0 to 359 °, with respect to the line of the Frame (which is normally aligned to North). -
Page 7: Effects Of Temperature, Barometric Pressure, Rainfall And Humidity
The on-board calibration (providing compensation for spar and transducer shadowing), can be disabled, returning the unit to raw, uncorrected operation Selection of the above parameters is via using Gill Wind software package or using a Terminal Program to set the FX or Px command. -

Page 9: Pre-Installation
5.5. Packaging Whilst the WindMaster HS is being moved to its installation site, the unit should be kept in its supplied Travelling Case. This should be retained for use if the unit has to be returned at any time. 5.6. -
Page 10: Connection
There are restrictions on the maximum cable lengths for correct operation. See 6.3 for cable specification. Power supply The WindMaster HS requires a DC supply of between 9 – 30 V DC. Typical current drain 55 mA @ 12 V (excluding analogue outputs) -
Page 11: Installation
Installation Guidelines As with any sophisticated electronics, good engineering practice should be followed to ensure correct operation. Always check the installation to ensure the WindMaster HS is not affected by other equipment operating locally, which may not conform to current standards, e.g. radio/radar transmitters, boat engines, generators etc. -
Page 12: Cable Type
6.4. Cable length The WindMaster HS is supplied with an integral 3 Metre, 9 pair, Belden 8774, 22awg, type cable fitted. The maximum cable length is dependent on the chosen communication format (RS232, RS422 or RS485), the baud rate, and, to a lesser extent, on the cable type and the local electrical ‘noise’ level. -
Page 13: Optional Windmaster Hs Cable Interface Box (Part 1951-Pk-021)
Optional WindMaster HS Cable Interface box (Part 1951-PK-021) An optional interface box may be purchased to extend the integral WindMaster HS 9 pair, 3 metre long lead. The Interface Box centre positioned M20 gland is suitable for the WindMaster HS cable (cables 8-13mm outer diameter) and the other two M16 glands for an Analogue Input/Output cable or Digital Output and Power cable (5-10mm outer diameter). -

Page 15: Connection To A Pc Using Rs 232
See 6.4 Using RS232, the cable length for reliable operation is limited to 6.5m (20ft) @ 9600 Baud. For longer cable runs, we recommend using the WindMaster HS configured with RS422 output, and a RS422/232 converter at the PC. See Section 10 Configuring. -
Page 16: Rs422 Connection To A Pc Via A Power And Communications Interface (1189-Pk-021)
When the PCI box is powered the Power LED will illuminate. When a WindMaster HS is connected as above to the PCI box and is set to output continuous data the PCI box RX LED will flash on/off at the WindMaster HS output rate thus giving a good indication that the WindMaster HS output is wired to the PCI box correctly and outputting RS422 data correctly. -

PCIA Box (1189-PK-020) WindMaster HS Analogue Output Connections. If a PCIA box is available then a WindMaster HS with Analogue Output option connections can be routed from the 15 Way D type Input connector directly to the Auxiliary 9 way D type Output connector. (Note: The PCIA box does not convert the digital output from the WindMaster HS to analogue outputs). -
Page 19: Using Rs485 2 Wire Point To Point Only
Analogue Outputs are also simultaneously available. The maximum poll rate is 10Hz in default SyncPoll 0 mode. The WindMaster HS can only be used in 2-wire mode in a Point-to-Point configuration; it cannot be networked with other devices on the 2-wire connection. -
Page 20: Mechanical Installation
Select a position so that the unit is clear of any structure, which may obstruct the airflow or induce turbulence. Do NOT mount the WindMaster HS in close proximity of high-powered radar or radio transmitters. A site survey may be required if there is any doubt about the strength of external electrical noise. -
Page 21: Grounding (Earthing) See Previous Illustration
Issue 4 August 2021 ________________________________________________________________________________________________________________________ Grounding (Earthing) See previous illustration For protection against lightning the WindMaster HS MUST be earthed via its mountings. An M4x8mm Pozi Pan Screw and associated crinkle washer is provided together with a M4 Terminal Tag. The screw is inserted into the thread provided adjacent to the cable gland outlet. -

Page 26: Polled Mode Notes General
Polled mode is only applicable to a single point to point system. When in the Polled mode, an output is only generated when the host system sends a Poll signal to the WindMaster HS consisting of the WindMaster HS Unit Identifier – that is, the relevant letter A – Z. -
