Resumen
El CR200X es un datalogger de bajo coste, fiable y de poco consumo. Compacto y adecuado para aplicaciones donde hay que medir pocas señales de sensores. Funciona muy bien en ubicaciones remotas para aplicaciones autónomas en adquisición de datos.
El datalogger utiliza el mismo lenguaje de programación que nuestros otros dataloggers, de forma que su funcionamiento es extremadamente flexible.
Note: End-of-Life Product: For new projects, the CR300-series dataloggers are recommended instead of the CR200X-series dataloggers. The CR300-series dataloggers build on the successful features of the CR200X-series dataloggers, while adding new features. The CR200X-series dataloggers will continue to be available for customers with existing CR200X networks until 16 January 2018.

-
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.
-
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.
-
A data logger can be programmed to initiate data transfer by using the SendVariables() or ModemCallback() instruction in CRBasic.
NOTE: These instructions are not supported in the CR200X operating system.
-
No, because it would not work. The SC32B is used to do the following:
- Convert datalogger logic levels (on the CS I/O port) to RS-232 levels
- Optically isolate the datalogger from the RS-232 peripheral
-
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.
-
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 datalogger. 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.
-
Some Campbell Scientific sensors with an RS-232 output are supported in Short Cut. Because of the large variety of serial data formats, other sensors require creating a program in the CRBasic Editor. CRBasic Editor is included in several of the purchased software packages, such as LoggerNet. For more information, see the “Interfacing Serial Sensors with Campbell Scientific Dataloggers” application note.
Note: The CR200X-series dataloggers have very limited serial capabilities.
-
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 datalogger. If the clock is updated too often, there is the risk of the datalogger 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 datalogger does not automatically adjust for DST. Data continuity can be maintained by keeping datalogger clocks on standard time.
In addition, if the datalogger’s internal 3 V battery is bad and the datalogger’s main 12 V power supply is cycled, the datalogger’s clock will reset to a default time.
-
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.
-
Data will only be lost if the datalogger’s internal 3 V battery is also bad. The “table definitions out of date” message simply implies that the datalogger 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 datalogger and should not affect data stored on the datalogger.
The datalogger 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 datalogger powers up
If the latter option is not set for the datalogger, the datalogger 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.

Información de compatibilidad adicional
Comunicaciones
El CR200X puede comunicar con el PC por conexión directa, interface Ethernet NL201, interface Wi-Fi NL240, por RS485 mediante MD485, y por telefonía móvil. Los datos pueden visualizarse mediante un móvil/tablet iOS o Android, teclado-display CD295 DataView II, o una PDA. Para usarlo con un dispositivo iOS o Android, debe descargarse la App LoggerLink desde Apple Store o Google Play
Periféricos de medida y control
El CR200X no es compatible con dispositivos SDM ni multiplexores.
Sensores
El CR200X puede medir variedad de sensores incluyendo sensores SDI-12 y señales 4-20 mA. No puede medir en modo diferencial y tampoco es compatible con los siguientes sensores: hielo/lluvia helada, temperatura y humedad del combustible, GPS, tiempo presente, flujo de calor en suelo, potencial de agua mátrico en suelo, galgas extensiométricas, termopares, RTDs.
Armarios
Las aplicaciones con poco consumo pueden utilizar la caja ENC200 para albergar el datalogger y la batería recargable #16869. En la caja ENC200 no caben un barómetro o batería mayor que la #16869. Sin embargo, es habitual utilizar las cajas ENC10/12 o ENC12/14 en la mayoría de aplicaciones que incluyen CR200X.
Fuentes alimentación
El CR200X requiere una fuente de alimentación externa, aunque incluye un regulador de carga. Si se utiliza el regulador de carga, la batería recargable debe ser de máximo 7Ahr. Si se utilizan baterías de mayor capacidad, la circuitería interior se calentará excesivamente. Esto será un problema si se produce una descarga profunda de la batería o hay alguna celda cortocircuitada. Campbell Scientific también recomienda que los paneles solares utilizados no superen los 10W y que los transformadores a 220Vac utilizados no superen 1A.
