The CR9000X is a large, modular multiprocessor system that provides precision measurement capabilities in a rugged, battery-operated package. It consists of a base system and a chassis with slots for up to nine user-selected I/O modules. The CR9000X is our fastest datalogger, with a measurement rate of 100,000 Hz, making it ideal for rapid sampling applications.
For the entire list of available I/O modules for the CR9000X and CR9000XC, visit the CR9000X-Series I/O Modules page.
Campbell Scientific also offers the CR9000XC, a compact version, that accepts up to five I/O modules.
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 datalogger 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 data logger 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.

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 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.

There are two ways to upgrade an operating system:
The maximum cable length depends on the interface being used.
RTMC Pro software is capable of email alarms. For example, an alarm could be set to trigger when there is a communication failure.
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.
The advantage of the BrHalf4W circuit is that the effect of lead resistance is measured and compensated for. The disadvantage is that it requires two differential (four single-ended) voltage input channels and four wires to the sensor.
Some sensors have four wires and are sensitive enough that the lead resistance would cause too great an error.
The BrHalf, a two-wire measurement, does not compensate for lead resistance.
The BrHalf3W lead compensation assumes that both leads are of the same resistance.
Use the full-bridge instruction, BrFull(). An example program for the CR1000 can be found in the “Datalogger Programming” section of the “ST350 Strain Transducer Instruction Manual.”
The voltage excitation channels are high impedance when not connected, meaning that internally they are isolated from the data logger ground. The connected sensor, however, may tie the voltage excitation channel to ground, such as through a completion resistor.
Data will only be lost if the data logger’s internal 3 V battery is also bad. The “table definitions out of date” message simply implies that the data logger is running a program that the PC software does not recognize. After successfully connecting, the message “updating table definitions” should appear. This means that the PC software has knowledge of the program running on the data logger and should not affect data stored on the data logger.
The data logger assigns two attributes for program files:
If the latter option is not set for the data logger, the data logger will not have a program running when it powers up, which will result in lost data. For more information, see the “How Do You Run?” article.
