Features
Measurement and Control Module
• 4 Mbyte memory*
• Program execution rate of up to 100 Hz
• CS I/O and RS-232 serial ports
• 13-bit analog to digital conversions
• 16-bit H8S Renesas Microcontroller with 32-bit
internal CPU architecture
• Temperature compensated real-time clock
• Background system calibration for accurate measurements over time and temperature changes
• Single DAC used for excitation and measurements
to give ratio metric measurements
• Gas Discharge Tube (GDT) protected inputs
• Data values stored in tables with a time stamp and
record number
• Battery-backed SRAM memory and clock ensuring
data, programs, and accurate time are maintained
while the CR1000 is disconnected from its main
power source
• Serial communications with serial sensors and
devices supported via I/O port pairs
• PakBus, Modbus, DNP3, TCP/IP, FTP, and SMTP
protocols supported
The module measures sensors, drives direct communications and telecommunications, reduces data, controls external devices, and stores data and programs in
on-board, non-volatile storage. The electronics are RF
shielded and glitch protected by the sealed, stainless
steel canister. A battery-backed clock assures accurate
timekeeping. The module can simultaneously provide
measurement and communication functions. The
on-board, BASIC-like programming language supports data processing and analysis routines.
Wiring Panel
The CR1000WP is a black, anodized aluminum wiring
panel that is compatible with all CR1000 modules. The
wiring panel includes switchable 12 V, redistributed
analog grounds (dispersed among analog channels
rather than grouped), unpluggable terminal block for
12 V connections, gas-tube spark gaps, and 12 V supply on pin 8 to power our COM-series phone modems
and other peripherals. The control module easily disconnects from the wiring panel allowing field replacement without rewiring the sensors. A description of
the wiring panel’s input/output channels follows.
*Originally, the standard CR1000 had 2 MB of data/program storage, and an optional version, the CR1000-4M, had 4 MB of memory. In September
2007, the standard CR1000 started having 4 MB of memory, making the CR1000-4M obsolete. Dataloggers that have a module with a serial number greater than or equal to 11832 will have a 4 MB memory. The 4 MB dataloggers will also have a sticker on the canister stating “4M Memory”.

Analog Inputs
Eight differential (16 single-ended) channels measure voltage levels. Resolution on the most sensitive
range is 0.67 µV.
Communication Protocols
Pulse Counters
Two pulse channels can count pulses from high level
(5 V square wave), switch closure, or low level AC signals.
The CR1000 supports the PakBus, Modbus, DNP3,
TCP/IP, FTP, and SMTP communication protocols.
With the PakBus protocol, networks have the distributed routing intelligence to continually evaluate links.
Continually evaluating links optimizes delivery times
and, in the case of delivery failure, allows automatic
switch over to a configured backup route.
Switched Voltage Excitations
Three outputs provide precision excitation voltages for
resistive bridge measurements.
The Modbus RTU protocol supports both floating
point and long formats. The datalogger can act as a
slave and/or master.
Digital I/O Ports
Eight ports are provided for frequency measurements,
digital control, and triggering. Three of these ports can
also be used to measure SDM devices. The I/O ports
can be paired as transmit and receive. Each pair has 0
to 5 V UART hardware that allows serial communications with serial sensors and devices. An RS232-tologic level converter may be required in some cases.
The DNP3 protocol supports only long data formats.
The dataloggers are level 2 slave compliant, with some
of the operations found in a level 3 implementation.
The TCP/IP, FTP, and SMTP protocols provide TCP/IP
functionality when the CR1000 is used in conjunction
with an NL115, NL120, or third party serial IP device.
Refer to the CR1000 manual for more information.
Power Supplies
CS I/O Port
AC-powered PCs and many communication peripherals
connect with the CR1000 via this port. Connection to
an AC-powered PC requires either an SC32B or SC-USB
interface. These interfaces isolate the PC’s electrical
system from the datalogger, thereby protecting against
ground loops, normal static discharge, and noise.
Any 12 Vdc source can power the CR1000; a PS100 or
BPALK is typically used. The PS100 provides a 7-Ahr
sealed rechargeable battery that should be connected
to a charging source (either a wall charger or solar
panel). The BPALK consists of eight non-rechargeable
D-cell alkaline batteries with a 7.5-Ahr rating at 20°C.
Also available are the BP12 and BP24 battery packs,
which provide nominal ratings of 12 and 24 Ahrs,
respectively. These batteries should be connected to a
regulated charging source (e.g., a CH100 connected to
a unregulated solar panel or wall charger).
RS-232 Port
This non-isolated port is for connecting a batterypowered laptop, serial sensor, or RS-232 modem.
Because of ground loop potential on some measurements (e.g., low level single-ended measurements),
AC-powered PCs should use the CS I/O port instead of
the RS-232 port (see above).
Enclosure/Stack Bracket
A CR1000 housed in a weather-resistant enclosure
can collect data under extremely harsh conditions.
The 17565 Stack Bracket allows a small peripheral
to be placed under the mounting bracket, thus
conserving space. With the bracket, the CR1000
can be attached in a “horizontal” orientation in
an ENC10/12 enclosure (i.e., the long axis of the
CR1000 spanning the short axis of the enclosure).
Peripheral Port
One 40-pin port interfaces with the NL115 Ethernet
Interface & CompactFlash Module, the NL120 Ethernet Interface, or the CFM100 CompactFlash® Module.
Switched 12 Volt
This terminal provides unregulated 12 V that can be
switched on and off under program control.
Storage Capacity
The CR1000 has 2 MB of flash memory for the Operating System, and 4 MB of battery-backed SRAM for CPU
usage, program storage, and data storage. Data is stored
in a table format. The storage capacity of the CR1000
can be increased by using a CompactFlash card.
Above shows a side view of the stack bracket. The
CR1000 is fastened to the bracket via Velcro straps.

Data Storage and Retrieval Options
To determine the best option for an application, consider the accessibility of the site, availability of services (e.g., cellular phone or
satellite coverage), quantity of data to collect, and desired time between data-collection sessions. Some communication options can
be combined—increasing the flexibility, convenience, and reliability of the communications.
Keyboard Display
The CR1000KD can be used to program the CR1000,
manually initiate data transfer, and display data. The
CR1000KD displays 8 lines x 21 characters (64 x 128
pixels) and has a 16-character keyboard. Custom
menus are supported allowing customers to set up choices
within the datalogger program
that can be initiated by a simple
“toggle” or “pick list”.
Multidrop Interface
The MD485 intelligent RS-485 interface permits a
PC to address and communicate with one or more
dataloggers over the CABLE3CBL cable. Distances
up to 4000 feet are supported.
Ethernet
Use of an NL120, NL115, or NL100 interface enables
the CR1000 to communicate over a local network or a
dedicated Internet connection via TCP/IP. The NL115
can also store data on a CompactFlash card.
One CR1000KD can be
carried from station to station in a CR1000 network.
Radios
Radio frequency (RF) communications are supported
via narrow-band UHF, narrow-band VHF, spread
spectrum, or meteor burst radios. Line-of-sight is
required for all of our RF options.
Portable Handheld Devices
An Archer-PCon or user-supplied PDA can be used to
collect and display the CR1000’s data, transfer datalogger programs, graph data for up to two elements, and
transfer the datalogger’s data to a PC. User-supplied PDAs
require either PConnect or PConnectCE software.
Telephone Networks
The CR1000 can communicate with a PC using landlines, cellular CDMA, or cellular GPRS transceivers.
A voice synthesized modem enables anyone to call the
CR1000 via phone and receive a verbal report of realtime site conditions.
Direct Links
AC-powered PCs connect with the datalogger’s CS I/O
port via an SC32B or SC-USB interface. These interfaces provide optical isolation. A battery-powered laptop can be attached to the CR1000’s RS-232 port via an
RS-232 cable—no interface required.
Satellite Transmitters
Our NESDIS-certified GOES satellite transmitter provides one-way communications from a Data Collection
Platform (DCP) to a receiving station. We also offer a
METEOSAT transmitter for European applications.
External Data Storage Devices
A CFM100 or NL115 module can store the CR1000’s data
on an industrial-grade CompactFlash (CF) card (2 GB
or less). The PC reads the CF card using either the CF1
CompactFlash Adapter or a 17752 USB Reader/Writer.
The CR1000 can also store data on an SC115 2-GB
Flash Memory Drive. This light-weight device can
easily be carried to the PC for data download.
CD295 DataView II Display
This two-line, 32-character LCD displays one real-time
value, a description, and units. It is typically mounted
in an enclosure lid, which allows customers to view the
CR1000’s data on-site without opening the enclosure.
Short Haul Modems
The SRM-5A RAD Short Haul Modem supports communications between the CR1000 and a PC via a fourwire unconditioned line (two twisted pairs).
This weather station at Denali National Park, Alaska, transmits data
via a GOES satellite transmitter.
4
Channel Expansion
4-Channel Low Level AC Module
The LLAC4 is a small peripheral device that allows
customers to increase the number of available lowlevel ac inputs by using control ports. This module is
often used to measure up to four anemometers, and is
especially useful for wind profiling applications.
Synchronous Devices for Measurement (SDMs)
SDMs are addressable peripherals that expand the datalogger’s measurement and control capabilities. For
example, SDMs are available to add control ports, analog
outputs, pulse count channels, interval timers, or even
a CANbus interface to the system. Multiple SDMs, in
any combination, can be connected to one datalogger.
Multiplexers
Multiplexers increase the number of sensors that can
be measured by a CR1000 by sequentially connecting
each sensor to the datalogger. Several multiplexers can
be controlled by a single CR1000.
The Network Planner, included in LoggerNet 4 or higher, generates device settings and configures the LoggerNet network map
for PakBus networks.
PC400, our mid-level software, supports a variety of
telemetry options, manual data collection, and data
display. For programming, it includes both Short Cut and
the CRBasic program editor. PC400 does not support
combined communication options (e.g., phone-to-RF),
PakBus® routing, or scheduled data collection.
RTDAQ is an ideal solution for industrial and realtime users desiring to use reliable data collection
software over a single telecommunications medium,
and who do not rely on scheduled data collection.
RTDAQ’s strength lies in its ability to handle the
display of high speed data.
The CR1000 is compatible with the AM16/32B (shown above)
and AM25T multiplexers.
Software
Starter Software
Our easy-to-use starter software is intended for first
time users or applications that don’t require sophisticated communications or datalogger program editing.
SCWin Short Cut generates straight-forward CR1000
programs in four easy steps. PC200W allows customers to transfer a program to, or retrieve data from a
CR1000 via a direct communications link.
LoggerNet is Campbell Scientific’s full-featured datalogger support software. It is referred to as “full-featured”
because it provides a way to accomplish almost all the
tasks you’ll need to complete when using a datalogger.
LoggerNet supports combined communication options
(e.g., phone-to-RF) and scheduled data collection.
At www.campbellsci.com/downloads you can download starter software at no charge. Our Resource CD
also provides this software as well as PDF versions of
our brochures and manuals.
Datalogger Support Software
Our datalogger support software packages provide
more capabilities than our starter software. These
software packages contains program editing, communications, and display tools that can support an entire
datalogger network.
Both LoggerNet and RTDAQ use View Pro to display historical
data in a tabular or graphical format.
Applications
The measurement precision, flexibility, long-term reliability, and economical price of the CR1000 make it ideal for scientific, commercial,
and industrial applications.
Meteorology
The CR1000 is used in long-term climatological monitoring, meteorological research, and routine weather
measurement applications.
Wind Profiling
Our data acquisition systems can monitor conditions
at wind assessment sites, at producing wind farms,
and along transmission lines. The CR1000 makes and
records measurements, controls electrical devices, and
can function as PLCs or RTUs. Because the datalogger has its own power supply (batteries, solar panels),
it can continue to measure and store data and perform
control during power outages.
Typical sensors for wind assessment applications include,
but are not limited to:
• three-cup and propeller
anemometers (up to
10 anemometers can be
measured by using two
LLAC4 peripherals)
Our rugged, reliable weather station measures
meteorological conditions at St. Mary’s Lake, Glacier
National Park, MT.
Sensors the CR1000 can measure include:
• cup, propeller, and
sonic anemometers
• thermistors, RTDs,
and thermocouples
• wind vanes
• tipping bucket rain
gages
• barometric pressure
sensors
• barometric pressure
• wind vanes
• RH sensors
• pyranometers
• cooled mirror
hygrometers
• ultrasonic ranging
sensor
• temperature sensors
• wetness
• solar radiation

farm in North Wales.
For turbine performance applications, the CR1000
monitors electrical current, voltage, wattage, stress,
and torque.
Agriculture and Agricultural Research
The versatility of the CR1000 allows measurement
of agricultural processes and equipment in applications such as:
Soil Moisture
The CR1000 is compatible with the following soil
moisture measurement technologies:
• Soil moisture blocks are inexpensive sensors that
estimate soil water potential.
• plant water research
• canopy energy balance
• Matric water potential sensors also estimate soil
water potential but are more durable than soil
moisture blocks.
• machinery performance
• plant pathology
• Time-Domain Reflectometry Systems (TDR) use a
reflectometer controlled by a CR1000 to accurately
measure soil water content. Multiplexers allow
sequential measurement of a large number of probes
by one reflectometer, reducing cost per measurement.
• crop management
decisions
• food processing/storage
• frost prediction
• Self-contained water content reflectometers are
sensors that emit and measure a TDR pulse.
• irrigation scheduling
• integrated pest
management

• sonic anemometers
This vitaculture site in
Australia integrates meteorological, soil, and crop
measurements.
• Tensiometers measure the soil pore pressure of
irrigated soils and calculate soil moisture.
6
Air Quality
The CR1000 can monitor and control gas analyzers,
particle samplers, and visibility sensors. It can also
automatically control calibration sequences and
compute conditional averages that exclude invalid
data (e.g., data recorded during power failures or calibration intervals).
Vehicle Testing
This versatile, rugged datalogger is ideally suited
for testing cold and hot temperature, high altitude,
off-highway, and cross-country performance. The
CR1000 is compatible with our SDM-CAN interface
and GPS16X-HVS receiver.
Road Weather/RWIS
Our fully NTCIP-compliant Environmental Sensor
Stations (ESS) are robust, reliable weather stations used
for road weather/RWIS applications. A typical ESS
includes a tower, CR1000, two road sensors, remote communication hardware, and sensors that measure wind
speed and direction, air temperature, humidity, barometric pressure, solar radiation, and precipitation.
Water Resources/Aquaculture
Our CR1000 is well-suited to remote, unattended
monitoring of hydrologic conditions. Most hydrologic
sensors, including SDI-12 probes, interface directly to
the CR1000. Typical hydrologic measurements:
• Water level is monitored with incremental shaft
encoders, double bubblers, ultrasonic ranging
sensors, resistance tapes, strain gage pressure
transducers, or vibrating wire pressure transducers.
Vibrating wire transducers require an AVW200series or another vibrating wire interface.
Vehicle monitoring includes not only passenger cars, but airplanes, locomotives, helicopters, tractors, buses, heavy trucks,
drilling rigs, race cars, and motorcycles.
The CR1000 can measure:
• Suspension—strut pressure, spring force, travel,
mounting point stress, deflection, ride
• Fuel system—line and tank pressure, flow,
temperature, injection timing
• Ionic conductivity measurements use one of the
switched excitation ports from the CR1000.
• Comfort control—ambient and supply air temperature, solar radiation, fan speed, ac on and off,
refrigerant pressures, time-to-comfort, blower current
• Samplers are controlled by the CR1000 as a function
of time, water quality, or water level.
• Brakes—line pressure, pedal pressure and travel,
ABS, line and pad temperature
• Alarm and pump actuation are controlled through
digital I/O ports that operate external relay drivers.
• Engine—pressure, temperature, crank position,
RPM, time-to-start, oil pump cavitation
• General vehicle—chassis monitoring, road noise,
vehicle position and speed, steering, air bag, hot/
cold soaks, wind tunnels, traction, CANbus, wiper
speed and current, vehicle electrical loads
A turbidity sensor was installed in a tributary of the Cedar
River watershed to monitor water quality conditions for
the city of Seattle, Washington.
Other Applications
• Eddy covariance systems
• Wireless sensor/datalogger networks
• Mesonet systems
• Avalanche forecasting, snow science, polar,
high altitude
• Fire weather
• Geotechnical
• Historic preservation
CR1000 Specifications
Electrical specifications are valid over a -25° to +50°C range unless otherwise specified; non-condensing environment required. To maintain electrical
specifications, Campbell Scientific recommends recalibrating dataloggers every two years. We recommend that the system configuration and critical
specifications are confirmed with Campbell Scientific before purchase.

The average period for a single cycle is determined by
measuring the average duration of a specified number
of cycles. The period resolution is 192 ns divided by
the specified number of cycles to be measured; the
period accuracy is ±(0.01% of reading + resolution).
Any of the 16 SE analog inputs can be used for period
averaging. Signal limiting are typically required for the
SE analog channel.
