1.0 INTRODUCTION
The Model 91000 ResponseONEtm Ultrasonic Anemometer is
a 2-axis, no-moving parts wind sensor. It is ideal for general
meteorological applications requiring accurate and reliable
measurement. The sensor features wide operating range, compact
size, easy installation and low power operation.
The sensor features durable corrosion-resistant construction
throughout. An internal compass provides wind direction orientation
when needed.
The ResponseONE installs on readily-available 1 inch (IPS)
pipe. Wiring connections are made in a convenient, weather-
proof junction box; special connectors and custom cables are not
needed.
Measured data is output in a serial format. NMEA, SDI-12, RMYT,
and ASCII protocols are available to suit many applications.
Continuous serial output or polled operation may be used.
RS-232 or RS-485 serial format options allows direct connection
to YOUNG displays, marine NMEA systems, data loggers, or other
compatible serial devices.
Operating parameters are easily reviewed and changed using the
ResponseONE CONFIG program available for download at www.
youngusa.com. All settings are stored internally in non-volatile
memory.

Figure 3.0 ResponseONE Features
The ResponseONE arrives fully calibrated and ready to use. As
supplied, the sensor is congured as follows:
FACTORY DEFAULT CONFIGURATION
Protocol: RS-232 ASCII Continuous
Baud Rate: 9600
Wind Format: Polar
Wind Units: m/s, Degrees azimuth
Default connections are shown in APPENDIX A, FIGURE A1.
Other options are also described in APPENDIX A. These are
accomplished using the ResponseONE CONFIG program which
is available at www.youngusa.com. Note: Always connect and
bench test a complex system before installation in the eld.
4.0 INSTALLATION
4.1 PLACEMENT
Proper instrument placement is important. Eddies from buildings,
trees, or other structures can inuence measurements. Locate
the sensor well away from obstructions. As a general rule, air ow
around a structure is disturbed to 10 times the height of the structure
downwind and 1-1/2 times the height of the structure above the roof.

4.2 MOUNTING AND ALIGNMENT
The ResponseONE mounts on standard 1-inch (IPS) pipe. This is
commonly available steel pipe with an outside diameter of 1.34 inches
(34 mm). The pipe should be secured vertically. Place the orientation
ring over pipe end with guide pin facing up. Do not tighten clamps yet.
Most applications require aligning the wind sensor array to
geographic north (0 degrees). In this orientation the junction box
faces SOUTH (180 degrees). See the diagram in APPENDIX B for
details. Two methods are suggested below :
4.2.1 ORIENTATION USING KNOWN GEOGRAPHIC DATA
(PREFERRED) Obtain accurate geographic data for the
installation site, this can be a topographic map, graphical
GPS map or detailed road map. Using the transducers
as a sighting aid, align the sensor with a remote feature
that represents the proper orientation. After alignment,
tighten the mounting post band clamp to secure the
position. DO NOT OVER-TIGHTEN. Engage orientation
ring pin with slot (Fig 4.2.3) in sensor base (under J-box).
Now tighten the band clamp on the orientation ring. If the
ResponseONE is later removed, the orientation ring will
preserve the sensor alignment. Compass is NOT enabled
for this method.

4.2.2 ORIENTATION USING BUILT-IN ELECTRONIC
COMPASS.
Note: Acclimate the ResponseONE to ambient
temperature at the installation site before calibrating.
Place ResponseONE sensor on mounting pipe, fully
seating it on the pipe and allowing for free rotation of
the sensor. Connect cable as indicated in APPENDIX
A and apply power to the system. (Refer to Fig 4.2.2)
With junction box cover removed, press and hold the
“CALIBRATE” button for 3 seconds; the indicator light
will blink rapidly to indicate that calibration mode is
active. Slowly rotate the sensor for 1-1/4 rotations. After
completing the rotations, press and hold the “CALIBRATE”
button again for 3 seconds; the indicator will double blink.
Within the next 60 seconds, tighten the mounting post band
clamp to secure the sensor. DO NOT OVER-TIGHTEN. At
this point, the compass will lock the direction of the sensor
and the ResponseONE will output correct wind direction
data; the indicator will continue to blink once per second.
Reattach J-Box cover and engage orientation ring as
shown in Fig 4.2.3 Tighten the orientation ring band clamp.
Important: Be sure to allow for magnetic declination in
your measurement. A declination value can be entered
using the ResponseONE CONFIG program or it can be
compensated in the data-logger program. Please note that
declination may change if the sensor is moved to a new
location. Accurate declination data can be obtained from
the following website:

program described in Section 6.0.

Page 4
91000-90(B)
5.1.1 ASCII
ASCII output format provides continuous measurement data in text
format at any of the available baud rates.
The wind measurement in ASCII output appears either in POLAR
(default) or CARTESIAN UV format. With POLAR format, the wind
speed threshold and wind speed units are user-selectable. With
CARTESIAN the wind threshold is ignored and wind speed units
are always meters per second (m/s).
ASCII POLAR FORMAT
a www.ww ddd.d ss*cc<CR>
where:
a = Sensor address
www.ww = Wind speed
ddd.d = Wind direction
ss = Status code
* = Asterisk (ASCII 42)
cc = Checksum
<CR> = Carriage return (ASCII 13)
ASCII CARTESIAN (UV) FORMAT
a uu.uu vv.vv ss*cc<CR>
where:
a = Sensor address
±uu.uu = U-axis wind speed (m/s)
±vv.vv = V-axis wind speed (m/s)
ss = Status code
* = Asterisk (ASCII 42)
cc = Checksum
<CR> = Carriage return (ASCII 13)
CHECKSUM is a two-character hexadecimal value (in printable
ASCII format) generated by taking the exclusive-or of all characters
up to the asterisk. STATUS CODE shows a non-zero value when the
sensor cannot acquire sufcient samples or a measurement error has
occurred. See APPENDIX C for more information on status codes.
5.1.2 ASCII POLLED
ASCII POLLED is like ASCII format described above except just
one serial output string is sent for each polling command received.
The polling command is Ma! where 'a' is the sensor address (valid
characters: 0-9, A-Z, a-z). The default address is '0' (ASCII 48).
5.1.3 RMYT
RMYT is a 6-byte binary data format sent at 9600 baud using RS-485
OUTPUT ONLY mode. It is for use with the YOUNG Model 06201
Wind Tracker.
5.1.4 NMEA
NMEA format provides continuous measurements in standard
NMEA marine sentences at 4800 baud. The ResponseONE must be
connected to a NMEA-capable device. Specic details of the NMEA
data string are below:
NMEA FORMAT
$WIMWV,ddd,R,www.w,u,A*cc<CR><LF>
where:
WI = Device type (weather instrument)
MWV = Wind direction and speed
ddd = Wind direction (degrees)
www.w = Wind speed
u = Wind speed units
S = mph
N = knots
K = kmph
M = m/s
A = Data status code: A=valid, V=invalid
* = Asterisk (ASCII 42)
cc = Checksum
<CR><LF> = Carriage return,Line feed (ASCII 13,10)
CHECKSUM is the two-character printable hexadecimal value
generated by taking the exclusive-or of all characters between '$'
and '*'.
5.2 SDI-12
SDI-12 stands for serial data interface at 1200 baud. It is often used
to interface battery powered data recorders with microprocessor
based devices designed for environmental data acquisition. SDI-
12 is typically used when low power usage is required. The SDI-12
device normally remains in a low power, standby state until it is polled
at which time a measurement is sent. SDI-12 can effectively address
multiple sensors on the same cable.
5.2.1 SDI-12 MEASUREMENT COMMANDS
Model 91000 uses the SDI-12 (v1.3) serial communication protocol
to initiate measurements and set sensor operation parameters.
The default sensor address is 0 (zero), and can be changed to
any valid single-character value if needed. Additional details about
the SDI-12 protocol may be found at www.sdi-12.org.
After initial power-up with 12 VDC, the sensor is in a low-
power standby state with a quiescent current of 4.2 mA. A valid and
properly addressed SDI-12 command wakes the sensor to initiate a
measurement, set or check operating parameters. After command
processing has nished, the sensor returns to the low-power standby
state.
SDI-12 'M' or 'C' commands initiate a measurement. The sensor
response message indicates the maximum time needed before
the measurement is ready, and data values will be available. The
maximum time ranges from 1 to 5 seconds depending on the Sample
Count.
If an 'M' command initiates a measurement, the sensor sends a
Service Request when the measurement is ready to be retrieved.
When the polling device receives the Service Request it then sends
a 'D' command to request measurement results from the sensor.
With 'C' commands, no Service Request is sent, and the polling
device must wait the full delay time before sending the 'D' command
to request the measurement.

IMPORTANT! PARAMETER CHANGES MUST BE STORED IN
FLASH MEMORY USING THE aXB! COMMAND OR THEY WILL
REVERT TO PREVIOUSLY STORED VALUES AT POWER UP.
The aXB! command may be sent after all changes have been
made, or not sent at all if the changes are temporary.
SAMPLE COUNT (aXSnnn!)
Each wind measurement is calculated from the median of multiple
wind samples. Each sample requires a power pulse so more samples
consume more power. The default sample count of 16 is a good
balance of low power consumption and robust performance. If winds
above 30 m/s are expected, 100 samples may be more suitable.
Winds reaching the performance limit of the sensor (70 m/s) may
require a setting of up to 800 samples.
THRESHOLD (aXTnnn!)
Threshold sets the minimum wind speed needed before a new polar
wind direction is calculated. The default value is 25 cm/s (0.25 m/s). A
greater-than-zero threshold can help provide more meaningful scalar
wind direction averages. The threshold for Cartesian (UV) output
format is automatically zero regardless of this setting.
5.3 LOW POWER OPERATION
Average current consumption with default settings is about 7.5 mA.
This conguration uses minimal power and enables all features even
though they may not be used. This is suitable for many low power
applications.
To reduce current consumption further, additional strategies include
disabling unused outputs, using polled serial operation, increasing
the output interval, and limiting the sample count to the minimum
optimal number. Faster baud rates also reduce power by limiting
transmit duration.

6.0 SETTING OUTPUTS AND OPERATING
PARAMETERS
6.1 SENSOR CONFIGURATION WITH ResponseONE CONFIG
PROGRAM (RECOMMENDED)
The YOUNG ResponseONE CONFIG program is available from the
factory web site: www.youngusa.com. It provides an easy method
for checking and conguring sensor operation. Install the program
on a Windows 7 or higher PC and follow instructions that appear
on the program screen to retrieve current sensor settings or send
new settings.
6.1.1 Opening the Program
After installing the program on your PC, click the desktop icon to open
the program. The following screen should appear:
Fig 6.1 ResponseONE CONFIG program opening screen
If you are using the ResponseONE for the rst time, the default
settings will appear. For reference these are:
FACTORY DEFAULT CONFIGURATION
Protocol: RS-232 ASCII Continuous
Baud Rate: 9600
Wind Format: Polar
Wind Units: m/s, Degrees azimuth
If these settings are correct for your application, then you may
proceed with operation of the device. If you wish to change any
settings, available options can be selected from menu items visible.
After changes are made, the ResponseONE CONFIG program
automatically saves the new settings in ash memory
6.2 SENSOR CONFIGURATION USING A GENERAL PURPOSE
COMMUNICATIONS PROGRAM
A general purpose text-based serial communications program like
HyperTerminal may be used to manually congure the sensor by
sending simple text commands. The following guidelines apply:
The YOUNG sensor and communication program must operate at
the same baud rate and be properly connected. Sensor RS-232
mode must be enabled. See the RS-232 wiring diagram, FIGURE
A1, in APPENDIX A.
Factory default sensor baud rate is 9600, Congure the serial
communications program for NO handshaking and 1 start, 8 data, 1
stop bit, no parity, no ow control.
The sensor must be in COMMAND MODE in order to set parameters.
Enter COMMAND MODE by sending three ESC characters (ASCII
27) in quick succession while the sensor is running. When the sensor
is in COMMAND MODE, it sends a '>' prompt character indicating
that it is ready to accept commands.
If the prompt does not appear after sending three indicating
characters, re-check wiring and communication program setup. If
the sensor baud rate is unknown, try sending the ESC characters
at each of the ve available baud rates (1200, 4800, 9600, 19200
and 38400). It is also possible that sensor parameters have been
purposely congured to disable RS-232 mode. If this is the case, the
following method must be used.
In order to provide access under all conditions, the sensor always
begins operation at power up with serial communications set to 38400
baud and RS-232 connections enabled. Immediately after power up,
there is a short time window in which to send the ESC characters
and enter COMMAND MODE.
To use this feature, set your serial communication program baud rate
to 38400. Remove power then wait 5 seconds. Re-apply power to
the sensor. The sensor will transmit four asterisks immediately after
power up. After the asterisks appear, send three ESC characters.
The COMMAND MODE '>' prompt should appear. To do this
using ResponseONE CONFIG, connect the ResponseONE to your
computer, open the program (make sure the correct serial port is
selected), then go to the 'COMMANDS' menu and select 'ACQUIRE
ResponseONE'.
A window will come up telling you that the serial port will be set to
38400 baud. Click 'OK' to continue. Then simply apply power to the
ResponseONE and the program will connect automatically.

Page 7
91000-90(B)
6.3 COMMAND OVERVIEW
After the '>' prompt appears, send '??' to display a list of available
commands. Send 'RPTV' to report current settings. (Note that some
values in the report are for factory settings and cannot be changed
by the user.)
Commands are case sensitive and the exact format must be used.
For example, the SET01nn command requires two digits for the serial
format code. If you send SET014 instead of SET0104 the sensor will
reject the command and indicate an error. End all commands with
a carriage return (ASCII 13). In HyperTerminal, do this by pressing
the ENTER key.
After receiving the carriage return, the sensor will evaluate the
command. Valid commands will be executed. Current settings can be
evaluated at any time by sending RPTV to get a new report.
IMPORTANT NOTE:
The YOUNG ResponseONE CONFIG program automatically
saves all settings to ash memory when they are sent to the
sensor. Settings that are changed manually must be saved to
ash with the SET77 command.

19 19200 baud
38 38400 baud
Usage example:
>SET0338 Sets baud rate to 38400.
SET04n Set wind speed units (ASCII, ASCII POLLED, NMEA
and SDI-12). Default value is 4.
Where n= 1 mph
2 knots
3 mph
4 m/s
Usage example:
>SET044 Sets wind speed to m/s.
SET05a Set sensor address for ASCII POLLED and
SDI-12. Note: This is the address when
polling with the “aM!” command (SDI-12) and
‘Ma!’ command (ASCII Polled) where 'a' is the
address. Default value is 0.
Where a= 0-9, A-Z, or a-z
Usage example:
>SET052 Sets polling address to number 2.
SET06nnn Set the wind speed threshold. Minimizes erratic
wind direction indications at very low wind
speeds. In polar mode, this allows the sensor
output to mimic a mechanical wind vane that
retains its orientation when there is no wind.
Default value is 25.
Where nnn= 000-150 cm/s
Usage example:
>SET06025 Sets wind speed threshold to 25 cm/s.
SET07nnnnn Set wind speed multiplier. Value is x10000. All
wind speed measurements are multiplied by this
parameter. Default value is 10000 for a multiplier
of 1.0000.
Where nnnnn= 00000-30000
Usage example:
>SET0709909 Sets multiplier to 0.9909
>SET0710023 Sets multiplier to 1.0023
SET08±nnnn Set wind direction offset. Value is degrees x10
and may be positive or negative. Wind direction
is always re-scaled to a 0-360 range after offset
is applied. Default value is 00000.
Where ±nnnn= -3600 to +3600
Usage example:
>SET08-0012 Offsets wind direction reading by -1.2 degrees
>SET08+0005 Offsets wind direction reading by +0.5 degrees
SET09dd Set damping factor. Default value is 00. This
means no damping is applied. High damping
values at long output intervals can slow the rate
at which indicated wind values change. Wind
measurement outputs are damped using the
following formula:
Sdamped = [(dd-1) * Sdamped + Ssample] / dd
Where dd= Damping factor (00-99)
Sdamped = New or last damped wind speed
Ssample = New wind speed
Usage example:
>SET0905 Sets damping factor to 5 (Note: Damping
factor only applies to wind reading.)

Page 8
91000-90(B)
SET10nnnn Set output interval. Sets the time interval
between measurements in one millisecond
increments. Lower values increase power
consumption when continuous measurements
are taken. Default is 1000.
Where nnnn= 0000-9999
Usage example:
>SET101000 Sets output interval to 1000 milliseconds
(1 second) (Note: If output interval is set
too low, the ResponseONE will automatically
calculate the minimum output interval.)
SET12nnn Set sample count. The rate at which the sensor
internally takes complete sonic wind samples
is greater than 200 times per second. This
command sets the number of internal samples
used to calculate the median measurement
result. Default is 16.
Where nnn= 000-800
Usage example:
>SET12016 Sets sample count to 16.
More internal samples consume more power
while providing greater immunity to conditions
like turbulent high-speed wind. Fewer samples
consume less power while providing less
immunity to disruptive conditions. This command
interacts with the OUTPUT INTERVAL setting.
More samples may require a longer output
interval.
SET13n Set ASCII output format. Determines whether
ASCII and ASCII POLLED serial outputs provide
wind data in either Polar (speed and direction)
or Cartesian (UV) form. Default is Polar.
Where n= 0 Polar
1 Cartesian (UV)
Usage example:
>SET130 Sets output format to polar.
SET25n Turn compass on or off. Default is 0.
Where n= 0 Off
1 On
Usage example:
>SET251 Turns compass on. Note: This command should
only be used if the sensor has been calibrated at
current location. Calibration automatically turns
on compass.
SET26nddmm Set compass (magnetic) declination.
M a g n e t i c d e c l i n a t i o n i s t h e a n g l e
between magnetic north and true north.
Where n= E, W, or 0 (East, West, or none)
dd= 00 to 90 degrees
mm= 00 to 60 minutes
Usage example:
>SET26W0606 Set declination to West 6° 6’ (zip code 49686)
SET77 Save all settings to non-volatile memory. Any
settings which have not been saved will be
lost when power is removed. Saved settings
are loaded at power up. This command may
be used any time the sensor is in COMMAND
MODE. Note: ResponseONE CONFIG
program automatically sends this command
when <Send Parameters> button is pressed.

Problem Solution
No Output • Check input voltage at sensor (10 – 30 VDC).
• Check wiring connections.
• Verify serial settings (baud rate, 1 stop bit, 8 data bits, no parity, no ow control).
• ‘Acquire’ the sensor with the ResponseONE CONFIG program (see section 6.2)
and verify setup mode.
One-way
communication
• Check wiring connections.
• ‘Acquire’ the sensor with the ResponseONE CONFIG program (see section 6.2).
• Change output mode to RS-485 full or half duplex, or RS-232.
Status codes
other than 00
appear
• Status codes other than 00 (or ‘A’ in NMEA mode) mean there is an error. See
‘Status Codes’ section for details.
No response to
poll command
• Check power supply.
• Check wiring connections.
• Verify serial settings (baud rate, 1 stop bit, 8 data bits, no parity, no ow control).
• Verify sensor address (if the sensor’s address is ‘0’, then the poll command is ‘0M!’
in SDI-12 mode and 'M0! in ASCII Polled mode.).
• ‘Acquire’ the sensor with the ResponseONE CONFIG program (see section 6.2)
and verify setup mode.
Direction is
incorrect
• If compass is off, make sure junction box is facing south.
• ‘Acquire’ the sensor with the ResponseONE CONFIG program (see section
6.2) and verify settings. Enable and calibrate compass if needed, enter compass
declination, and set the wind direction offset (default is 0000).
• Turn compass on and calibrate if needed.
Status codes for ASCII output are hex values added together before output (a status code of 03 would be a
code of 01 and 02). NMEA only allows for ‘acceptable’ or ‘void’ data. SDI-12 does not show a status code.
Status Code Meaning
00 Valid data
01 Transducer path A blocked or dirty, clear blockage and clean transducers
02 Transducer path B blocked or dirty, clear blockage and clean transducers
04 Transducer path C blocked or dirty, clear blockage and clean transducers
A NMEA data acceptable (NMEA wind data only)
V NMEA data void (NMEA wind data only)
