CR206

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 datalogger 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 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 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 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.
