3.4.3 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).

3.5 Analog 4-20 mA
3.5.1 Analog 4-20 mA Wiring
The Analog 4-20 mA is an analog protocol that has no sentences.
CHANNEL 1

• YELLOW –> VDC+
• GREEN –> VDC-

CHANNEL 2

• WHITE –> VDC+
• BROWN –> VDC-

CONNECTION INSTRUCTIONS
Channel 2 connection is mandatory. We connect channel 2 to the power supply, you will have 10 seconds to connect channel 1 if you want to use it in parallel. If not connected, only the first of the named channels will be configured.
The default configuration is the following:

• Channel 1 –> Address Mode
• Channel 2 –>Tunnel Mode

These configurations can be modified according to needs thanks to the configurator that we have available.

3.5.2 Analog 4-20 mA Configuration
To configure the equipment, Channel 2 (White/Brown cables) must be connected to the power, Thus, the device will appear in the configurator application (via Bluetooth).
At this point we can choose between different modes:

• Speed Mode: In this configuration, speed reading (0-45m/s), scaled in a range of 4-20mA, is given through the channel we select.
• Address Mode: In this configuration, wind reading [0-359º] , scaled in a range of 4-20mA.
• Tunnel Mode: In this configuration you select the combination of wind speed and direction. As in many purposes it is not necessary to know the direction of wind but the direction of the same, the tunnel mode has been implemented.

Power consumption:
Ultra-Low-Power 4-20 analog: 4-20 mA, @12-24V, 1Hz.

3.5.2 Analog 4-20 mA Configuration (II)
This protocol divides the measurement range into two parts. When the wind direction is between 0º and 180º the dimensioning used is 4mA-12mA; while between the angles [180º – 359º] the dimensioning is between 12mA – 20mA. OPERATION
For the correct operation of the equipment, it is required that channel 2 must be powered.
Once the device is connected, it will take approximately 10 seconds to start. Once the 10 seconds have passed, the equipment will begin to launch the relevant currents through the wires (Depending on the configuration established).

4.7. Mounting accessories
A wide range of accessories can be used with the device. The ULP PRO can be mounted on a flat service and screwed on to different sizes of poles. It can also be used with an adaptor for poles of 39 mm.

• Please, visit our website and check all the accessories available and their possible combinations at www.calypsoinstruments.com. 4.8. Firmware
  Upgradable via RS485 or UART/TTL
  4.9 Product Material
  The ULP PRO 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 locks the wave path. The input wires are protected by Transient Voltage Suppression (TVS) diodes. The instrument body is inject molded.
  4.10 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 and configurable via cable using the configurator ( https://calypsoinstruments.com/technical-information).
A USB converter cable is available as an accessory on calypsoinstruments.com.

General information

6.1. 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 natural north, bow of a boat, or the marker used as a reference .
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.

6.2. Maintenance and repair
The ULP does not require great maintenance given the new design of non- moveable parts.
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 stop working.
The ULP can be wiped clean with a damp cloth being careful to not touch the transducers.

6.3 Warranty
This warranty covers the defects resulting from defective parts, materials and manufacturing, if made known to the manufacturer within 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 by the user will not incur any responsibility on part of Calypso Instruments; therefore, any harm caused to the ULP by a mistake will not be covered by the waranty. Using assembly elements different from those delivered with the product will void the waranty.
Changes on transducers position/alignment will void any warranty.
For further information please contact Calypso Technical Support through [email protected] or visit www.calypsoinstruments.com.
