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.
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 information 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.

They use the same protocol, but the CR800 PakBus protocol is less limited in its capability.
No, because it would not work. The SC32B is used to do the following:
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 maximum cable length depends on the interface being used.
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 Data loggers” application note.
Note: The CR200X-series data loggers have very limited serial capabilities.
The SC32B is not needed for a data logger that has an RS-232 port. If the RS-232 port is not being used by another peripheral, the port can be used with a serial cable or a serial-to-USB cable to connect to the computer.
It is not possible to connect two data loggers to one modem and transmit data from both data loggers. However, two data loggers can be networked together so that data is sent from one data logger to the other, and then the data logger connected to the modem can transmit the data from both data loggers.
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.
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.
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.
