Overview
The CR206 Datalogger features an on-board 900 MHz spread-spectrum radio with the functionality of the CR200 Datalogger. The CR206's input channel configuration and small size is optimal for measuring one or two sensors.
When paired with an ENC200 enclosure and the small 16869 battery, the packaged CR206 has a deployment size of only 6 in. by 7 in. This small package is optimal for the CR206 to be used as a wireless sensor within a PakBus network. The CR206 measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master data logger. For more information on how to configure a PakBus system, please read our PakBus Networking Guide in the Related Documents section.
If an alternate spread-spectrum radio is required, see our CR211 and CR216 dataloggers.
Benefits and Features
- Ideal where only a few sensors will be measured
- Stores 128,000 data points (nonvolatile)
- Data format is table-based

Compatibility
Campbell Scientific’s SDM devices and multiplexers are not supported.
Sensors
The CR206 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 CR206 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 CR206's internal spread spectrum radio can transmit data to other CR206 loggers or RF401 spread spectrum radios. Certain CR206 settings must match the RF401 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 CR206 is in the transparent mode, it can communicate with the retired CR205 loggers or RF400 radios.
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 CR206-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.

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.

Frequently Asked Questions
Number of FAQs related to CR206: 1
-
A practical maximum is to connect one multiplexer per every two control terminals on the data logger. 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.
