Detailed Description

The CR1000 consists of a measurement and control module and a wiring panel. This datalogger uses an external keyboard/display and power supply. Low power consumption allows the CR1000 to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR1000 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The CR1000's 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.

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.

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”.

Compatibility

Sensors

With several channel types, the CR1000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors (via a terminal input module, such as the CURS100). A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR1000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement & Control Peripherals

The CR1000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

The CR1000 communicates with a PC via direct connect, Ethernet interfaces, multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat).

Data can be viewed on the CR1000KD Keyboard Display, the CD100 Mountable Display with Keyboard, an iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

Compatible external data storage devices are the CFM100, NL115, and SC115.

Enclosures

The CR1000 and its power supply can be housed in any of our standard enclosures. 

Power

Any 12 Vdc source can power the CR1000 datalogger. Power supplies commonly used with the CR1000 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 Ah rating at 20°C.

Both the PS150 and PS200 consist of a sealed rechargeable 7 Ah battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS150 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.

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 CH100 or CH200 connected to a unregulated solar panel or wall charger).

Software

CRBasic, the CR1000's full programming language, supports simple or complex programming and many onboard data reduction processes. Compatible software includes:

  • Short Cut
  • PC200W
  • PC400 (version 1.2 or higher)
  • LoggerNet (version 3.0 or higher)
  • RTDAQ (version 1.0 or higher)
  • PConnect (version 3.1 or higher)
  • PConnectCE (version 2.0 or higher)
  • VisualWeather (version 2.0 or higher)

Downloads

CR1000 OS v.28.02 (4.09 MB) 07-08-2015

Execution of this download installs the CR1000 Operating System and Compiler on your computer.  It also updates the CR1000 support files for the CRBasic Editor.  

Note: This OS has crossed the 2 Meg CR1000 size limit for remote download.  The OS must be downloaded to the 2 Meg CR1000 via direct connect with the Device Configuration Utility.  All OS download methods are supported by the 4 Meg CR1000.

Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive.  This is due to a change in the format of the file system from FAT16 to FAT32.  In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32.  Any programs stored and running from the CPU drive will be lost.  It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.).  In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

Frequently Asked Questions

Number of FAQs related to CR1000: 161

Expand AllCollapse All

  1. For the CR10X and CR200X, raw readings from half-bridge measurements are in millivolts. For the CR1000, each reading is a ratiometric number between 0 and 1 (signal voltage/excitation voltage).
  2. A voltage outside of ±5 V present on one of the analog channels can cause self-calibration to fail. Disconnect all sensors, cycle power, and check if the error remains. If self-calibration fails with no sensors attached, consult an application engineer about sending the datalogger to Campbell Scientific for repair.
  3. Use the PreserveVariables() instruction to ensure that all variables reflect the last known value if the datalogger experiences power loss.

  4. Load the string to a buffer in the SDM-SIO4, and issue the command to send the string. For details, see the SDM-SIO4 Instruction Manual.

  5. Only one CWB100 can be connected to each odd channel control port. For the CR800 and CR850, this relates to two total units—one on C1 and one on C3. On the CR1000 and CR3000, this amounts to four total units.

    Putting more than one CWB100 on a datalogger will NOT speed up sensor data collection. Only one CWB100 should be accessed at any given time, or the devices will interfere with each other. If multiple CWB100 devices are connected to a single datalogger, the data collection schedules for the CWB100 devices should be staggered. Sufficient time should be built in to allow each base unit to collect data from all of the remote sensors associated with it and to allow for any needed retries.

  6. For the CR1000, to get continuous analog outputs, an SDM-AO4A (4-channels, non-isolated, voltage only) or an SDM-CVO4 (4-channels, isolated, voltage or current) is needed. Multiples of these devices can be used to get more outputs.  For single channels of output, some third-party devices can be used.

  7. Yes. By configuring the NL120 as a CSDC device, both the NL120 and COM320 can share the same CS I/O port. The CR1000 and CR3000 are capable of multi-threading, so the NL120 and COM320 can run in parallel. For more information, refer to the NL120 Ethernet Module Instruction Manual.

  8. The lithium battery voltage is measured by the datalogger once per day, and the value is held in the Status table when it is running normally. The voltage is normally extremely stable if the datalogger is powered from another source and its temperature is stable. A new battery supplies approximately 3.6 Vdc; it should be replaced when its reading is at or below 2.7 Vdc.

    The lithium battery voltage is also read when the datalogger is reset or its program is recompiled.

  9. The internal file storage on the datalogger has limits on the size, quantity, and name length of files. The file name of the new file may need to be shortened, or some older files may need to be deleted using File Control.

  10. RS-232 is not a multidrop interface. This means that the connection can only be between two devices. SDI-12 and RS-485 two-wire are multidrop interfaces, allowing several devices to be connected to the same port. Only a single RS-232 device may be connected to a COM port. Using an RS-485 to RS-232 interface, several RS-485 devices may be connected to a single COM port.
