Descrição Técnica

The CR9000X's base system includes a CR9032 CPU module, CR9041 A/D module, CR9011 power supply module, and 128-MB SDRAM memory for program and data storage. The CR9000X's internal battery has a 14-Ahr capacity.

A mix of I/O modules is selected based on the measurements required for the application. Campbell Scientific offers a large variety of modules. Individual I/O modules can be swapped out, allowing the system to be reconfigured if requirements change.

I/O modules whose model numbers end in an E (e.g., CR9051E, CR9055E) and the CR9052DC include an easy connector module. Easy connector modules allow sensor wiring to remain connected while the input module’s measurement electronics and the rest of the data logger system are used elsewhere.

The CR9000X has a choice of enclosure.  The environmental enclosure is designed for field applications, where the enclosure will be exposed to the elements. The lab enclosure is for applications where the CR9000X will reside inside a building.

CR9000X versus CR9000

In August 2004, the CR9000X replaced the CR9000. The CR9000 and CR9000X dataloggers differ in their CPU Module; the CR9000 datalogger uses the CR9031 and the CR9000X datalogger uses the CR9032.

The CR9032 CPU module supports a measurement rate of up to 100,000 Hz, provides a 180 MHz clock speed, and adds a built-in RS-232 port, 10baseT/100baseT port, CS I/O port, and PC-card slot. The built-in ports enable communication without using the special interfaces (e.g., PLA100, TL925, NL105) that were required for the retired CR9000 datalogger. The PC-card slot allows the CR9000X to store data on a Type I, Type II, or Type III PCMCIA card, or on a CompactFlash® card if an adapter is used.

A CR9000 may be upgraded to a CR9000X by replacing the CR9031 CPU module with the CR9032 CPU module.

Additional Compatibility Information

Compatibility with Retired Products

Customers can add CR9000X dataloggers to networks containing the older CR9000 or CR9000C dataloggers. I/O modules other than the CR9080 can be used with either the CR9000 or CR9000X. CR9000 communication interfaces (i.e., NL105, BLC100, TL925, PLA100) are not compatible with the CR9000X, and therefore have been retired.


With several channel types, the CR9000X is compatible with many sensors, including thermocouples and 4 to 20 mA sensors.

Measurement and Control Peripherals

Measurement and control peripherals typically used with the CR9000X are our AM25T 25-Channel Solid State Multiplexer, SDM-CAN Interface, SDM-INT8 Eight Channel Interval Timer, and SDM-SIO4 Serial Input/Output Module. Other measurement and control peripherals are compatible but they do not support the CR9000X datalogger's maximum measurement rate and are therefore impractical for most CR9000X applications.


The CR9000X typically communicates with a PC via direct connect or Ethernet. Because the CR9000X has an on-board 10baseT/100baseT port, an Ethernet interface such as the NL201 is not required. 

Storage capacity can be increased by using a PC or CompactFlash card. The CR9000X's PCMCIA card slot supports one Type I, Type II, or Type III PC Card or the CF1 adapter and one CompactFlash (CF) card.

The storage capacity of Type II cards exceeds 1 GB. Type III cards provide data storage capacities exceeding 1 GB but may not be suitable for all environments. Campbell Scientific offers several CF cards that have passed our ESD testing and operate properly with our data loggers (see Ordering tab). Please note that the PCMCIA and CompactFlash cards need to be industrial-grade and have a storage capacity of 2 GB or less.

Other communication peripherals are compatible but they do not support the CR9000X datalogger's maximum measurement rate and are therefore impractical for most CR9000X applications.


Two enclosures are offered for the CR9000X. The 8253 fiberglass environmental enclosure is designed for field applications where the enclosure will be exposed to the elements. The 8255 lab enclosure is for applications where the CR9000X will reside inside a building.


CRBasic, the CR9000X's full programming language, supports simple or complex programming and many on-board data reduction processes. CRBasic is included in RTDAQ, LoggerNet, and PC400.

RTDAQ Real-Time Data Acquisition Software must be ordered separately; the CR9000X is also compatible with other Campbell Scientific software.

  1. The CR9000X and CR9000XC differ only in the number of I/O cards they can hold. The CR9000X can hold 9 I/O cards, and the CR9000XC can hold 5 I/O cards. We provide both sizes to accommodate our customers; the same I/O cards can be used in either chassis.

  2. There are two ways to upgrade an operating system:

    Method 1

    1. Connect to the CR9000X using the serial link or the Ethernet link.
    2. Use the RTDAQ | Clock/Program Tab | Send Program… button.
    3. In the Files Type box in the file browser window, use the drop-down arrow to select OBJ Files (*.obj). Browse to the computer file where the desired operating system resides.
    4. Double-click the file, or click the Open button. A warning will appear.
    5. After reading the warning, click Yes to begin downloading the new operating system.

    Method 2

    1. Download and install the Device Configuration Utility software, or launch it from RTDAQ.
    2. Connect the CR9000X RS-232 port to the computer.
    3. Select CR9000X from the list in the Device Configuration Utility.
    4. Select the Send OS tab, and follow the instructions displayed in the software interface screen.
  3. The CR3000 program will have to be modified so that each measurement or control instruction includes the appropriate module number. Some parameters might differ as well.
  4. Yes. The simplest method is to use conditional program statements that execute most of the code based on time. For example, the data could be scheduled to log at 6 a.m. and finish at 8 p.m. using CRBasic instructions such as TimeIntoInterval(). Another option is to use an IfThen/EndIf construction that does a logical test of light-level measurements based on a light sensor. An additional option is to use calculated sunrise and sunset times along with a combination of RealTime() and Case instructions.

    For more information, see the “Decisions, Decisions, Decisions…” article. 

  5. The maximum cable length depends on the interface being used.

    • RS-232 connections will reach 15 m (50 ft).
    • RS-485 connections go beyond 610 m (2,000 ft).
    • IP connections can be routed worldwide. 
  6. Common causes include the following:

    • Loss of power to the data logger and the program Run On Power-up attribute not being set (For help with this, see the “How Do You Run?” article.)
    • A FillStop instruction in a CRBasic program used to set data tables to stop storing new data when full
    • Logical conditions for writing to data tables that do not evaluate as TRUE

  7. No, because it would not work. The SC32B is used to do the following:

    • Convert data logger logic levels (on the CS I/O port) to RS-232 levels 
    • Optically isolate the data logger from the RS-232 peripheral 
  8. The data logger will not reset the SW12 unless it is done under program control using the SW12() or PortSet() instructions, or unless the data logger compiles or recompiles a program. This could be done when a new program is sent to the data logger, or if the power is cycled.

  9. The CRBasic Editor Help contains example program code for all instructions in the data logger. Look for the Example link at the top of each instruction topic. The CRBasic Help Tutorial demonstrates how to access this and other online CRBasic Editor Help files.

    Also, many programming examples can be found in the data logger and sensor manuals that are available on the Campbell Scientific website.
