CR210 Datalogger with 922 MHz Spread Spectrum Radio


The CR210 was a small, low-cost datalogger with an internal 922 MHz spread spectrum radio. It was replaced by the CR211, which has improved communication capability. The CR210 can be used within a CR211(X) network, but the CR211(X) needs to be in the transparent mode. Contact one of our application engineers for details.

Communications RS-232



The CR210's internal spread spectrum radio can transmit data to other CR210 loggers or RF410 radios. It can also communicate with CR211(X) loggers, RF411 radios, or RF431 radios if they are set to the transparent mode. Certain CR210 settings must match the radio's settings for communications between the datalogger 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. 

The CR210 can communicate with a PC via direct connect, NL100 Ethernet interface, MD485 multidrop modem, and digital cellular modems. Data can be viewed on the CD295 DataView II display, Archer-PCon Field PC, or a user-supplied PDA (PConnect or PConnectCE software required).

Measurement & Control Peripherals

The CR210 is not compatible with SDM devices and multiplexers.


The CR210 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.

Other Sensors

  • CS15 Current Transformer

  • 255-100 Evaporation Gauge
  • 237 and LWS leaf wetness sensors
  • WXT520 Weather Transmitter


Applications with minimal power requirements can use the ENC200 enclosure to house the datalogger 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 CR210-based systems.

Power Supplies

The CR210 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 Ahr or smaller. Using larger batteries with the datalogger'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.


The CR210 is compatible with the following software packages:

  • Short Cut
  • PC200W
  • PC400 (version 1.0 or higher)
  • LoggerNet (version 2.1 or higher)
  • PConnect (version 3.0 or higher)
  • PConnectCE (version 2.0 or higher)
  • VisualWeather (version 2 or higher)

Frequently Asked Questions

Number of FAQs related to CR210: 2

  1. The CR200X-series and the retired CR200-series dataloggers are NOT compatible with SDMs or multiplexers. If more channels are needed or may be needed in the future, consider purchasing a CR800, CR850, or CR1000 instead.

  2. A practical maximum is to connect one multiplexer per every two control terminals on the datalogger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
