The CR9000XC, a compact version of the CR9000X, holds up to five user-selectable I/O modules. It is a modular, multiprocessor system that provides precision measurement capabilities in a rugged, battery-operated package. It consists of an environmental enclosure, a base system, and a chassis containing slots for the I/O modules.
The CR9000X series is our fastest data logger series, with a measurement rate of 100,000 Hz and a clock speed of 180 MHz, making it ideal for rapid sampling applications.
Campbell Scientific also offers the CR9000X, a larger version, that accepts up to nine I/O modules. For more information, visit the CR9000X Product Info page.Read More

Customers can add CR9000XC dataloggers to networks containing the older CR9000 or CR9000C dataloggers. I/O modules other than the CR9080 can be used with either the CR9000 series or CR9000X series. CR9000 series communication interfaces (i.e., NL105, BLC100, TL925, PLA100) are not compatible with the CR9000XC, and therefore have been retired. RTDAQ software is not compatible with the older CR9000(C). Customers can upgrade a CR9000C datalogger to a CR9000XC datalogger by replacing the CR9000C's CR9031 CPU module with the contemporary CR9032C CPU module.
With several channel types, the CR9000XC is compatible with many sensors, including thermocouples and 4 to 20 mA sensors.
Measurement and control peripherals typically used with the CR9000XC 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 CR9000XC datalogger's maximum measurement rate and are therefore impractical for most CR9000XC applications.
The CR9000XC typically communicates with a PC via direct connect or Ethernet. Because the CR9000XC has an on-board 10baseT/100baseT port, an Ethernet interface such as the NL100 is not required.
Storage capacity can be increased by using a PC or CompactFlash card. The CR9000XC'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 CF cards that store up to 2 GB of data. 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 CR9000XC datalogger's maximum measurement rate and are therefore impractical for most CR9000XC applications.
The CR9000XC includes a non-corrosive, sealed, aluminum enclosure that provides protection from water, dust, and most environmental pollutants.
CRBasic, the CR9000XC'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 CR9000XC is also compatible with other Campbell Scientific software.

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.
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.

Common causes include the following:
The maximum cable length depends on the interface being used.
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.
The available COM ports listed in the COM Port drop-down menu are supplied to PC400 by the Windows Operating System (OS). If there are no COM ports shown for selection, it most likely means that there are no COM ports registered with the Windows OS. This can be confirmed using the Windows Device Manager (Control Panel | Device Manager | Ports).
Most modern laptops are not equipped with native RS-232 COM ports. In this situation, a USB-to-RS-232 adapter cable must be used to connect to the data logger. Even when the drivers for this device have been properly installed, the derived COM port will not be shown for selection until the cable is attached to the laptop.
If small amounts of data are transferred per transmission, it will not be a problem. Larger amounts of data can overrun buffers in the modem, causing lost data. In that situation, lower the baud rate on the data logger to avoid the issue.
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.
