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”.

Communication Protocols
Analog Inputs
Eight differential (16 single-ended) channels measure voltage levels. Resolution on the most sensitive
range is 0.67 µV. 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 RS-232-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 NL240, NL200, NL115, or NL120. 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.
Typically, the CR1000 is powered with a PS200, PS100,
or BPALK. The PS200 and PS100 provide a 7-Ah
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-Ah rating at 20°C. Also available are the BP12 and BP24 battery packs,
which provide nominal ratings of 12 and 24 Ah, respectively. These batteries should be connected to a regulated charging source (e.g., a CH200 or CH100 connected
to a unregulated solar panel or wall charger).
RS-232 Port
This non-isolated port is for connecting a battery-
powered 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).
Peripheral Port
One 40-pin port interfaces with the NL115 Ethernet
Interface & CompactFlash Module, the NL120 Ethernet Interface, or the CFM100 CompactFlash® Module. The PS200 (at right)
and CH200 are microcontroller-based smart
chargers that have two
input terminals that allow
simultaneous connection
of two charging sources.
Switched 12 Volt
This terminal provides unregulated 12 V that can be
switched on and off under program control.
Storage Capacity
Enclosure/Stack Bracket
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.
A CR1000 housed in a weather-resistant enclosure can
collect data under extremely harsh conditions. The
28960 Enclosure Stack Mounting Kit allows a small peripheral to be placed under the mounting bracket,
thus conserving space. 3
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 CABLE2TP two-twisted pair
cable. Distances up to 4000 feet are supported.
Internet and IP Networks
Campbell Scientific offers several interfaces that enable
the CR1000 to communicate with a PC via TCP/IP. Radios
Radio frequency (RF) communications are supported
via narrowband UHF, narrowband VHF, spread spectrum, or meteor burst radios. Line-of-sight is required
for all of our RF options.
One CR1000KD can be
carried from station to station in a CR1000 network.
iOS Devices, Android Devices, and PDAs
An iOS device, an Android device, our Archer-PCON
Field PC, or a user-supplied PDA can be used to view
and collect data, set the clock, and download programs. To use an iOS or Android device, go to the
Apple Store or Google Play and purchase our LoggerLink Mobile Apps. 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.
Satellite Transmitters
Our NESDIS-certified GOES satellite transmitter
provides one-way communications from a Data Collection Platform (DCP) to a receiving station. Campbell
Scientific also offers an Argos transmitter that is ideal
for high-latitude applications.
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. External Data Storage Devices
A CFM100 or NL115 module can store the CR1000’s
data on an industrial-grade CompactFlash (CF) card. The CR1000 can also store data on an SC115 2-GB
Flash Memory Drive. Mountable Displays
The CD100 and CD295 can be mounted in an enclosure lid. The CD100 has the same functionality
and operation as the CD1000KD, allowing both data
entry and display without opening the enclosure. The
CD295 displays real-time data only.
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.

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 ResourceDVD 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.
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
•tipping bucket rain gages
•wind vanes
•pyranometers
•ultrasonic ranging sensor
•thermistors, RTDs, and thermocouples
•barometric pressure sensors
•RH sensors
• cooled mirror hygrometers

Soil Moisture
The CR1000 is compatible with the following soil
moisture measurement technologies:
•Soil moisture blocks are inexpensive sensors that estimate soil water potential.
•Matric water potential sensors also estimate soil water potential but are more durable than soil moisture blocks.
•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.
•Self-contained water content reflectometers are
sensors that emit and measure a TDR pulse.
•Tensiometers measure the soil pore pressure of irrigated soils and calculate soil moisture.
Agriculture and Agricultural Research
The versatility of the CR1000 allows measurement of agricultural processes and equipment in applications such as:
•plant water research
•canopy energy balance
•machinery performance
•plant pathology
•crop management decisions
•food processing/storage
•frost prediction
•irrigation scheduling

Typical sensors for wind assessment applications include, but are not limited to:
•sonic anemometers
•three-cup and propeller anemometers (up to 10 anemometers can be measured by using two LLAC4 peripherals)
•wind vanes
•temperature sensors
•barometric pressure
•wetness
•solar radiation
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.
•Ionic conductivity measurements use one of the
switched excitation ports from the CR1000.
•Samplers are controlled by the CR1000 as a function of time, water quality, or water level.
•Alarm and pump actuation are controlled through
digital I/O ports that operate external relay drivers.
A turbidity sensor was installed in a tributary of the Cedar River
watershed to monitor water quality conditions for the city of
Seattle, Washington.
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
•Comfort control— fan speed, ambient and supply
air temperature, refrigerant pressures, solar radiation, ac on and off, time-to-comfort, blower current
•Brakes—line pressure, pedal pressure and travel,
ABS, line and pad temperature
•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
Other Applications
•Eddy covariance systems
•Wireless sensor/datalogger networks
•Mesonet systems
•Avalanche forecasting, snow science, polar, high altitude
•Fire weather
•Geotechnical
•Historic preservation
