The CR200X, our smallest lowest-cost data logger, provides stand-alone operation in harsh, remote environments. It reads input from one or two sensors, then transmits the data using communication peripherals. CRBasic, its full programming language, supports simple or complex programming. Multiple CR200Xs can be configured as a network, or units can be deployed individually.Read More
The CR200X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.
The CR200X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples (refer to the Compatibility tab for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR200X datalogger.

The CR200X can communicate with a PC via direct connect, NL201 Network Link Interface, NL240 Wi-Fi Network Link, MD485 multidrop modem, and digital cellular modems. Data can be viewed on an iOS device, an Android device, CD295 DataView II Display, or a user-supplied PDA. To use an iOS or Android device, go to the Apple Store or Google Play and download our LoggerLink Mobile Apps free of charge. User-supplied PDAs require either PConnect or PConnectCE software.
The CR200X is not compatible with SDM devices and multiplexers.
The CR200X can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. It cannot make differential measurements and is not compatible with the freezing-rain/ice, fuel moisture/temperature, geographic position, present weather, soil heat flux, soil matric water potential, and strain sensors listed on our price lists.
Applications with minimal power requirements can use the ENC200 enclosure to house the data logger and the pn 16869 sealed rechargeable battery. The ENC200 cannot house a barometer or a battery that is larger than the pn 16869. However, an ENC10/12 or ENC12/14 enclosure is adequate for most CR200X-based systems.
The CR200X uses an external power supply and has a built-in regulator. When connected to the on-board charging circuit, the sealed rechargeable battery should be 7 A h or smaller. Using larger batteries with the data logger's built-in charger may result in excessive PC board heating. This is especially a concern when the battery is deeply discharged or failing with a shorted cell. Campbell Scientific also recommends that solar panels be 10 W or less and wall chargers be 1 A or smaller.
Execution of this download installs the Operating System and Compiler on your computer for the following dataloggers:CR200X, CR206X, CR211X, CR216X and CR295X. It also updates the support files for the CRBasic Editor.
Note: Newer CR206X dataloggers (serial # ≥ 19122) and newer CR211X dataloggers (serial # ≥ 19143) have 250 mW radios that must use OS 3 or higher for their datalogger operating system.

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 IfTime(). 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.
The maximum cable length depends on the interface being used.
The internal battery is not rechargeable. In the case of low internal battery voltage, data will only be maintained as long as a power supply is connected. Collect all data from the datalogger before disconnecting the power.
The battery, a 15598, is not user replaceable. The datalogger should be returned to Campbell Scientific to have the battery replaced. To request a returned material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.
Technically, the SRM-5A is compatible with the CR200X-series dataloggers, but it is more complicated to use it with these dataloggers. To use a SRM-5A with a CR200X-series datalogger, the SRM-5A must be in the DTE position on the station modem. In addition, user-supplied adapters and gender changers are needed to complete the connections between the SRM-5A and the RS-232 port of the datalogger. Contact Campbell Scientific for more information.
Not directly. If the CS15-L is connected to a CR200(X) datalogger, the datalogger can take the ac measurement and control a solid-state relay based on some threshold within the datalogger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the datalogger can trigger it with a small 5 Vdc mA signal.) For more information, see the “Measurement and Control Peripherals” section of the operator’s manual.
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 datalogger to avoid the issue.
One of the simpler ways to approximate how long it will take for a data table to fill up is to open the LoggerNet Connect screen, click the Station Status button, and view the Table Fill Times tab.
It is not possible to connect two dataloggers to one modem and transmit data from both dataloggers. However, two dataloggers can be networked together so that data is sent from one datalogger to the other, and then the datalogger connected to the modem can transmit the data from both dataloggers.
The CRBasic Editor Help contains example program code for all instructions in the datalogger. 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 datalogger and sensor manuals that are available on the Campbell Scientific website.
It is possible to upgrade the OS without downloading each OS version between the existing one on the datalogger and the most current one available. For example, a CR1000 can be upgraded directly from OS 14 to OS 25. However, when a large jump in OS versions is made, the upgrade will likely restructure the Status table and the Setting table, and they will need to be manually reloaded.
Note that in many instances, an OS update may not be necessary. Before updating, check the OS Revision History to see if a newer version would provide desired benefits.
