1. Product overview
Thank you for choosing the ULP STD wind
meter from Calypso Instruments. This is the
first model or our generation II, representing an
important technology breakthrough condensing
an extensive R+D investment:
· Both shape and firmware have been enhanced
for an improved rain performance. This is key for
static applications such as weather stations.
· Mechanical design has been revamped making
the unit more robust and dependable.
· We feel very proud to release a unit that requi-
res under 0.4 mA of power at 5V, sampling at
1Hz.
· Different output options available: RS485,
UART/TTL and MODBUS.
Applications for the ULP STD are the following:
Weather Stations | Drones
Temporary Scaffolding and construction |
Infrastructures and building | Cranes
Spraying | Irrigation | Fertilizing | Precision
Agriculture
Smart Cities | Wild fires | Shooting | Scientific
Sailing.

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.
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 upgradable. Configurable via cable
using the configuratior ( https://calypsoinstru-
ments.com/technical-information). A USB
converter cable is available as an accessory on
calypsoinstruments.com.
The ULP STD can be set up by using a special
configuration app made by Calypso Instru-
ments.
In order to use the app, you should download the
configurator from our website at
www.calypsoinstruments.com.
To configure your device, connect the ULP via
either a USB to RS485 converter cable (in case
of the ULP RS485 or the ULP Modbus) or via a
USB to UART converter cable (in case of the ULP
UART). Connect all the ULP cables except for the
brown cable to the converter. Insert the USB into
the computer, open the configurator app, select
the configuration wanted and follow the instruc-
tions on the screen to finish the configuration.

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).
Power consumption:
Ultra-Low-Power (I2C): 0,15 mA @5V, 1Hz.
6.4.3 I2C Sentences
General Options
Address I2C-0x15 ( 21 decimal )

to write
2 bytes, the I2C bus direction and the register
you need to check.

• 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.
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 approxi-
mately 10 seconds to start. Once the 10 seconds
have passed, the equipment will begin to launch
the relevant currents through the wires (Depen-
ding on the configuration established).
7. General information
7.1. 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 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 exam-
ple, the mast head on a boat.
6.5 Analog 4-20 mA Wiring, Configura-
tion and Registers
6.5.1 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 configu-
red.
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.
6.5.2 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.

Any wrongful use given by the user will not incur
in any responsibility on part of Calypso Instru-
ments. 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 guaran-
tee.
by the warantee. Using assembly elements diffe-
rent 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@calypsoins-
truments.com or visit www.calypsoinstru-
ments.com.
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 con-
tact us directly.
7.2. 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 stop working.
The ULP can be wiped clean with a damp cloth
being careful to not touch the transducers.
7.3 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.
