Product Material
The ULP STD is engineered to be a robust device with minimal downtime. This new shape has been designed for optimum water spillage which implies lower probability of ice formation. Frost might affect measurements if it blocks the wave path. The input wires are protected by Transient Voltage Suppression (TVS) diodes. The instrument body is built with Polyamide.

Quality Control
Every single unit is calibrated with accuracy, following the same calibration standards for each one in a wind tunnel.
A Q/C report for both wind speed and direction is generated and kept in our files. Standard deviation is checked to guarantee that each unit has been calibrated to the highest standards

Firmware

Firmware upgradable. Configurable via cable using the configuratior ( https://calypsoinstruments.com/technical-information). A USB converter cable is available as an accessory on calypsoinstruments.com.

Configuration Options

Non applicable to the ULTRASONIC NMEA 2000 model.
The ULP STD can be set up by using a special configuration app made by Calypso Instruments. In order to use the app, you should download the configurator from our website at www.calypsoinstruments.com.

RS485 and UART Sentences
MWV Wind Speed and Angle
1 2 3 4 5
| | | | |
$–MWV,x.x,a,x.x,a*hh

1. Wind Angle, 0 to 360 degrees
2. Reference, R = Relative, T = True
3. Wind Speed
4. Wind Speed Units, K/M/N
5. Status, A = Data Valid
6. Checksum

By default, the communication parameters are 38400bps, 8N1.
Some examples of sentences are:

• $IIMWV,316,R,06.9,N,A*18
• $IIMWV,316,R,06.8,N,A*19

The connection is straightforward with no configuration required in RAW mode configuration.
In case of ON DEMAND configuration mode, the sentence received is almost the same, but there is a need of this sentence for requesting data every time you ask for data:

• $ULPI*00\r\n //I=id node by default
• $ULPA*08\r\n
• $ULPB*0B\r\n
• P1*78\r\n

The received sentence has this structure, slightly modified: $IiMWV,x.x,a,x.x,a*hh, being i the node (I,A,B,C,….) configured.

I2C Sentences
General Options

• Address I2C- 0x15 ( 21 decimal )
• Frecuency -100kHz – 400kHz
• SDA -TX (Yellow)
• SCL – RX (Green)

Write Register
In order to write about the register it is necessary to write 2 bytes, the I2C bus direction and the register you need to check.

• I2C Address (1 Byte) + Register Address (1 Byte)
• Address -0x15 (21 decimal)
• Available Registers:
• Wind Raw Stat – 0x10
• Wind 2 Min Stat – 0x12
• Wind 5 Min Stat – 0x15
• Wind 10 Min Stat – 0x1A
• Wind Full Stats – 0x1F

Read Register
For the read register we need to take into account how many bytes is the system giving us back and what bytes we need to read in order to obtain the value we need. Data are under big-endian criteria. The first byte, the more valuable one to be represented. E.g. If 2 bytes are read, byte 0 and byte 1, we will read the first byte as 0x05 and second byte 0x0A.

The first byte is marked in orange. The more valuable one.
The second byte is marked in blue ( less significant one LSB).

General information

General recommendations
Wind Speed Gust is that value that measures abrupt and sudden change in wind speed. Regarding mounting the unit, align the north mark of the ULP towards the north. Regarding mounting the unit, the mast head has to be prepared for the mechanical installation. Align the North mark of the Ultrasonic Ultra-Low- Power to the north. Make sure to install the sensor in a location free from wind perturbation, usually on the mast head. Make sure to install the sensor in a location free from anything that obstructs the flow of wind to the sensors within a 2 meter radius, for example, the mast head on a boat.
Other important aspects:

• Do not attempt to access the transducers area with your fingers;
• Do not attempt any modification to the unit;
• Never paint any part of the unit or alter its surface in any way.
• NOT allow to be submerged fully or partially in water.

If you have any questions or doubts, please contact us directly.

Maintenance and repair

• The ULP does not require great maintenance thanks to the lack of the moving parts in this new design.
• Transducers must be kept clean and aligned. Impacts or incorrect impulsive handling may lead to transducers misalignment.
• The space around the transducers must be empty and clean. Dust, frost, water, etc… will make the unit s top working.
• The ULP can be wiped clean with a damp cloth being careful to not touch the transducers.

Warranty

This warranty covers the defects resulting from defective parts, materials and manufacturing, if such defects are revealed during the 24 months after the purchase date. Warranty is void in case of non-following the instructions of use, repair or maintenance without written authorisation. Any wrongful use given by the user will not incur in any responsibility on part of Calypso Instruments. Therefore, any harm caused to the ULP by a mistake will not be covered by the warantee. Using assembly elements different from those delivered with the product will void the guarantee. by the warantee. Using assembly elements different from those delivered with the product will void the guarantee. Changes on transducers position/alignment will avoid any warranty. For further information please contact Calypso Technical Support through sales@calypsoinstruments.com or visit www.calypsoinstruments.com.

MODBUS Sensor Data Requests
Measurements all have a resolution of 0.1 but are reported as 10*. 8.2 m/s is returned as a value 82. The user must /10 in order to reinsert the decimal precision.
