概要
The CR206X is a small, low-cost data logger that includes an internal 900 MHz spread-spectrum radio for transmitting data to another CR206(X), an RF401(A) radio, or an RF430 radio. The 900 MHz frequency is used in the US and Canada.
The CR206X 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 CR206Xs can be configured as a network, or units can be deployed individually.

詳細
The CR206X 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 CR206X measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master data logger. The master data logger must support 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.
The CR206X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.
The CR206X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples (refer to the Compatibility information for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR206X datalogger.

Communications
The CR206X 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 CR206X's internal spread spectrum radio can transmit data to other CR206(X) loggers, RF401A radios, RF401 radios, or RF430 radios. Certain CR206X 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. Refer to the Quick Reference Guide for Setting Up RF401-to-CR206(X) Communications application note for more information.
If the CR206X is in the transparent mode, it can communicate with the retired CR205 loggers or RF400 radios.
Measurement & Control Peripherals
The CR206X is not compatible with SDM devices and multiplexers.
Sensors
The CR206X 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 CR206X-based systems.
Power Supplies
The CR206X 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.
Operating System Considerations
Newer data loggers with 250 mW radios must use OS 3 or higher for their data logger operating system.

よくある質問
CR206Xに関するよくある質問の数： 41
すべて展開すべて折りたたむ
-
In theory, a single RF430 can communicate with 4,000 CR206X dataloggers, as this is the maximum number of unique PakBus addresses available for use in a single RF network. The practical limit depends on how frequently data is retrieved from all the remote sites.
-
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.
-
Not directly. If the CS15-L is connected to a CR200(X) datalogger, the data logger can take the ac measurement and control a solid-state relay based on some threshold within the data logger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the data logger 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.

はい。BMP5 Direct SDK は、次の 2 つの条件が満たされている限り、データロガーと通信できます。
- データロガーとコンピュータ間の通信リンクは透過的です。
- 過度の遅延はありません。
-
Current data loggers compatible with the BMP5 Direct SDK are the CR200X-series, CR1000, CR3000, CR800, and CR850.
Retired compatible data loggers include the CR10X-PB, CR23X-PB, and CR510-PB. These data loggers must have the optional PakBus operating system installed, which is available on the Downloads page of our website.
-
いいえ。このシナリオでは、ベース RF401A は、transparent通信プロトコルを介して RF400 デバイスとのみ通信でき、PakBus プロトコルを介して CR206X データロガーとのみ通信できます。
-
Are the CR200X, CR206X, CR211X, CR216X, or CR295X dataloggers compatible with SDMs and multiplexers?
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.

技術的には、SRM-5A は CR200X シリーズ データロガーと互換性がありますが、これらのデータロガーで使用するのはより複雑です。SRM-5A を CR200X シリーズ データロガーで使用するには、SRM-5A をステーション モデムの DTE 位置に配置する必要があります。さらに、SRM-5A とデータロガーの RS-232 ポート間の接続を完了するには、ユーザー提供のアダプタとジェンダー チェンジャーが必要です。詳細については、Campbell Scientific にお問い合わせください。
-
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 data logger to avoid the issue.
-
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 data logger before disconnecting the power.
The battery, a 15598, is not user replaceable. The data logger should be returned to Campbell Scientific to have the battery replaced. To request a return material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.
ケーススタディ
2012 年 8 月、RESPEC は、ルイジアナ州ナポレオンビル岩塩ドームの西側斜面で発生しつつある陥没穴に現場計測機器と早期警報監視サービスを提供する契約を締結しました。地下深くの塩水洞窟で構造的な亀裂が発生し、周囲の堆積物が洞窟に流れ込み、地表に陥没穴ができ、かき乱された堆積物からガスが放出されました。時間が経つにつれて、陥没穴は 40 エーカー以上に拡大し、最大深度では 400 フィートを超えました。 RESPEC のエンジニアは、発生しつつある陥没穴の周囲の傾斜と水位を継続的に監視するために、リアルタイムの早期警告システムを導入しました。陥没穴は沿岸のヒノキ沼地にあるため、監視システムは過酷な条件 (例: 猛暑、極度の湿度、ハリケーン、大雨、昆虫) で最小限のメンテナンスで稼働する必要がありました。このシステムは、Campbell Scientific のデータ......続きを読む
水資源コンサルティングおよびサービス会社である RESPEC は現在、ニューメキシコ州カールスバッドにある旧 I&W 施設の下にある塩水洞窟の早期警報システムの運用と保守の契約を結んでいます。この塩水洞窟は、地表から 450 フィート下にある塩層であるサラドの溶液採掘によって形成されました。 塩水は、ドリルビットの周囲と上部の溶解を防ぐために塩を掘削する際によく使用され、塩層に真水を注入して溶解を促し、その後塩水を汲み出すことで採掘されます。このプロセスによって地下の洞窟が形成され、規制当局は、2008年にニューメキシコ州で崩壊した他の2つの洞窟に似ている可能性があると結論付けました。 カールスバッド塩水洞窟は、崩壊の危機に瀕していると考えられており、隣接する住宅地、米国の主要幹線道路 2 本、農場および牧場の店舗、教会、および南側の大規模農業コミュニティを支えるカールスバッド灌漑地区の運河に直接影響を及ぼす可能性があります。また、崩壊により塩水が上部の帯水層に流れ込み、地元の地下水が塩分で汚染される可能性もあります。 2009 年 4 月以来、RESPEC は地表沈下監視と早期警報システムの提供を任されています。RESPEC は当初、近くの監視井戸に 4......続きを読む
