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.

常见问题解答

CR200X: 39

展开全部收起全部

  1. 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. 

  2. 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.

  3. 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.

  4. 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.

  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. Current data loggers compatible with the BMP5 Direct SDK are the CR200X-series, CR1000, CR3000, CR800, and CR850.

    Retired compatible data loggers include the CR10X-PB, CR23X-PB, and CR510-PB. These data loggers must have the optional PakBus operating system installed, which is available on the Downloads page of our website.

  7. 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.

  8. Yes, but only with a direct connection, such as an RS-232 cable or a USB-to-serial adapter. While connected to the data logger, press the Send Program button on the Clock\Program tab, and browse to the program file. 

  9. They use the same protocol, but the CR800 PakBus protocol is less limited in its capability.

  10. If the automatic clock synchronization option (LoggerNet [version 4] Setup, Datalogger, Clock tab) is used, do not set the Allowed Clock Deviation too tight (for example, 1 s), as the PC will try to change the clock either because of drift in its own clock or because of delays in the communication from the PC to the data logger. If the clock is updated too often, there is the risk of the data logger skipping records if the time is pushed forward just before it is supposed to store data.

    Although most PCs are usually synchronized with Internet time, the default update time is several days, and a PC can typically drift tens of seconds in that period.

    Clock issues also appear when changing to or from daylight saving time, as the data logger does not automatically adjust for DST. Data continuity can be maintained by keeping data logger clocks on standard time.

    In addition, if the data logger’s internal 3 V battery is bad and the data logger’s main 12 V power supply is cycled, the data logger’s clock will reset to a default time.
