Overview

The CR216X is a small, low-cost datalogger that includes an internal 2.4 GHz spread-spectrum radio for transmitting data to another CR216(X), an RF416 radio, or RF432 radios. The 2.4 GHz frequency can be used worldwide.

The CR216X provides stand-alone operation in harsh, remote environments. It reads input from one or two sensors, then transmits its data wirelessly via its internal radio. Multiple CR216Xs can be configured as a network, or units can be deployed individually.

Technical Description

The CR216X can be used in a wireless sensor network. Wireless sensor networks are appealing because they are often more economical than trenching, laying conduit, and pulling wire. When used as a wireless sensor, the CR216X measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master datalogger. The master datalogger must use the PakBus communication protocol (e.g., CR800,CR850, CR1000, CR3000). For more information on how to configure a PakBus system, please read our PakBus Networking Guide (see sidebar).

The CR216X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.

The CR216X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples (refer to the Compatibility tab for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR216X dataloggers.

Additional Compatibility Information

Communications

The CR216X 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 CR216X's internal spread spectrum radio can transmit data to other CR216(X) loggers, RF416 radios, or RF430 radios. Certain CR216X 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.

If the CR216X is in the transparent mode, it can communicate with the retired CR215 loggers or RF415 radios.

Measurement & Control Peripherals

Campbell Scientific’s SDM devices and multiplexers are not supported.

Sensors

The CR216X 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 #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 CR216X-based systems.

Power Supplies

The CR216X 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.

  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. 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. 
  3. 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.

  4. The internal battery is not rechargeable. In the case of low internal battery voltage, data will only be maintained as long as a power supply is connected. Collect all data from the datalogger before disconnecting the power.

    The battery, a 15598, is not user replaceable. The datalogger should be returned to Campbell Scientific to have the battery replaced. To request a returned material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.

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

  6. 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.

  7. Starting with LoggerNet 4.0, there is a tab in the Setup screen to retrieve a file stored on one of the datalogger drives from the datalogger on a schedule.

    • In LoggerNet 4.0, the tab is named Image Retrieval.
    • In LoggerNet 4.1, the tab is named File Retrieval.
  8. One of the simpler ways to approximate how long it will take for a data table to fill up is to open the LoggerNet Connect screen, click the Station Status button, and view the Table Fill Times tab.

  9. The CRBasic Editor Help contains example program code for all instructions in the datalogger. 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 datalogger and sensor manuals that are available on the Campbell Scientific website.

  10. This might happen because the datalogger clock is being adjusted by a remote time source. If this occurs close to the same time that the datalogger 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 datalogger. 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 datalogger’s station status or Status table and look for skipped scans, watchdogs, and low 12 V counts.
