Overview

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.

Additional Compatibility Information

Communications

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.

Measurement & Control Peripherals

The CR200X is not compatible with SDM devices and multiplexers.

Sensors

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.

Enclosures

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.

Power Supplies

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.

Frequently Asked Questions

Number of FAQs related to CR200X: 37

Expand AllCollapse All

  1. 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. 
  2. 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.

  3. 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. 

  4. Not directly. If the CS15-L is connected to a CR200(X) datalogger, the data logger can take the ac measurement and control a solid-state relay based on some threshold within the data logger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the data logger 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.

  5. 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:

    • Run now: specifies the file should be run as the current program
    • Run on power up: specifies that the file should be run as the program when the data logger powers up

    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. 

  6. Yes. Both the RavenXTV (Verizon) and the RavenXTG (AT&T) are available.

  7. Technically, the SRM-5A is compatible with the CR200X-series dataloggers, but it is more complicated to use it with these data loggers. 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 data logger. Contact Campbell Scientific for more information.

  8. This might happen because the data logger clock is being adjusted by a remote time source. If this occurs close to the same time that the data logger is due to store data, it can result in either a skipped record or an additional record of data.

    If LoggerNet 4 is used to collect data on a schedule, check the setup for that data logger. Look at the settings on the Clock tab in the LoggerNet Setup Screen. If that is enabled, the clock is checked and set at midnight every day and may interfere with data collection at that same time.

    Skipped scans and power outages could also result in records missing from a data table. Check the data logger’s station status or Status table and look for skipped scans, watchdogs, and low 12 V counts.

  9. It is possible to upgrade the OS without downloading each OS version between the existing one on the data logger 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.

  10. 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.
