Overview
The CR211 Datalogger integrates an on-board 922 MHz spread-spectrum radio with the functionality of the CR200 Datalogger, providing both measurement and telecommunication capability in one small package.
The CR211's input channel configuration and small size are optimal for measuring one or two sensors. When paired with an ENC200 enclosure and the small 16869 battery, the packaged CR211 has a deployment size of only 6 inches by 7 inches. If an alternate spread-spectrum radio is required, see our CR206 and CR216 dataloggers.
Benefits and Features
- Ideal where only a few sensors will be measured
- Replaces our CR210 Data Logger

Compatibility
Campbell Scientific’s SDM devices and multiplexers are not supported.
Sensors
The CR211 cannot make differential measurements and is not compatible with thermocouples, our geographic position sensor, fuel moisture/temperature probe, and soil heat flux sensors. However, it can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. Our CS625 Reflectometer, 109 Thermistor, and CS15 Electric Current Sensor were specifically developed for our CR200-series dataloggers. Other compatible sensors include wind sets, tipping buckets, and barometers. For a complete list of compatible sensors, see the CR200-series brochure.
Communications
The CR211 can communicate with a PC via direct connect, NL100 Ethernet interface, MD485 multidrop modem, and our digital cellular modems. Data can be viewed on the CD295 DataView II display or a PDA (PConnect or PConnectCE software required).
The CR211's internal spread spectrum radio can transmit data to other CR211 loggers or RF411 spread spectrum radios. Certain CR211 settings must match the RF411 settings for communications between the data logger and radio to be successful. The factory default settings of these devices do not match; therefore, they must be reconfigured before communications can take place. Refer to the following application note for more information.
Quick Reference Guide for Setting Up RF401-to-CR206 Communications
If the CR211 is in the transparent mode, it can communicate with the retired CR210 loggers or RF410 radios.
Enclosures
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 CR211-based systems.
Power Supplies
When connected to the on-board charging circuit, the sealed rechargeable battery should be 7 Ahr 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.
Compatible software
- Short Cut
- PC200W
- PC400 (version 1.0 or higher)
- LoggerNet (version 2.1 or higher)

Before March 2005, a CD was shipped with PakCom PC software and PakBus ActiveX (OCX). Effective, 3 March 2005, our DevConfig, PC200W, and Short Cut packages began to include support for the CR200-series dataloggers. These programs are available for download from our website or are on our ResourceCD.
