The CR206X 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 CR206X's internal spread spectrum radio can transmit data to other CR206(X) loggers, RF401A radios, RF401 radios, or RF430 radios. Certain CR206X settings must match the radio's settings for communications between the data logger and radio to be successful. The factory default settings of these devices might not match; therefore, they may need to be reconfigured before communications can take place. Refer to the Quick Reference Guide for Setting Up RF401-to-CR206(X) Communications application note for more information.
If the CR206X is in the transparent mode, it can communicate with the retired CR205 loggers or RF400 radios.
The CR206X is not compatible with SDM devices and multiplexers.
The CR206X 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 #16869 sealed rechargeable battery. The ENC200 cannot house a barometer or a battery that is larger than the #16869. However, an ENC10/12 or ENC12/14 enclosure is adequate for most CR206X-based systems.
The CR206X 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.
Newer data loggers with 250 mW radios must use OS 3 or higher for their data logger operating system.
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.
In theory, a single RF430 can communicate with 4,000 CR206X dataloggers, as this is the maximum number of unique PakBus addresses available for use in a single RF network. The practical limit depends on how frequently data is retrieved from all the remote sites.
Yes. The BMP5 Direct SDK can communicate with the data logger as long as two conditions are met:
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.
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.
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.
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.
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.
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.
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 data logger. 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.
No, because it would not work. The SC32B is used to do the following:
