技术说明

CR216X可用于无线传感器网络应用中。其具有吸引力,是因为比起挖沟、埋管、穿线起来,无线传感器网络经常更经济一些。此时,CR216X测量所连接的传感器,再把数据通过自己的射频电台无线地发送到主数据采集器上。主数据采集器必须支持PakBus通讯协议(例如:CR800、CR850、CR1000、CR3000)。查找如何关于如何设置PakBus系统的更多信息,请阅读我们的PakBus网络系统指导。

CR216X具有几个输入通道,可以测量一系列的传感器。气体放电管为输入通道提供了坚固耐用的电子放电保护功能。

CR216X不可以作差分测量,也不支持SDM设备、扩展板或热电偶(参阅兼容性标签查找可兼容的传感器、外设和软件)。没有提供给CR216X数据采集器的再校准服务。

Additional Compatibility Information

Communications

The CR216X 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 CR216X's internal spread spectrum radio can transmit data to other CR216(X) loggers, RF416 radios, or RF430 radios. Certain CR216X 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.

If the CR216X is in the transparent mode, it can communicate with the retired CR215 loggers or RF415 radios.

Measurement & Control Peripherals

Campbell Scientific’s SDM devices and multiplexers are not supported.

Sensors

The CR216X 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 CR216X-based systems.

Power Supplies

The CR216X 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.

常见问题解答

CR216X: 40

展开全部收起全部

  1. 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.

  2. 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. 

  3. Technically, the SRM-5A is compatible with the CR200X-series dataloggers, but it is more complicated to use it with these data loggers. To use a SRM-5A with a CR200X-series datalogger, the SRM-5A must be in the DTE position on the station modem. In addition, user-supplied adapters and gender changers are needed to complete the connections between the SRM-5A and the RS-232 port of the data logger. Contact Campbell Scientific for more information.

  4. 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.

  5. This might happen because the data logger clock is being adjusted by a remote time source. If this occurs close to the same time that the data logger is due to store data, it can result in either a skipped record or an additional record of data.

    If LoggerNet 4 is used to collect data on a schedule, check the setup for that data logger. Look at the settings on the Clock tab in the LoggerNet Setup Screen. If that is enabled, the clock is checked and set at midnight every day and may interfere with data collection at that same time.

    Skipped scans and power outages could also result in records missing from a data table. Check the data logger’s station status or Status table and look for skipped scans, watchdogs, and low 12 V counts.

  6. Some Campbell Scientific sensors with an RS-232 output are supported in Short Cut. Because of the large variety of serial data formats, other sensors require creating a program in the CRBasic Editor. CRBasic Editor is included in several of the purchased software packages, such as LoggerNet. For more information, see the “Interfacing Serial Sensors with Campbell Scientific Dataloggers” application note.

    Note: The CR200X-series dataloggers have very limited serial capabilities.

  7. 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.

  8. The maximum cable length depends on the interface being used.

    • RS-232 connections will reach 15 m (50 ft).
    • RS-485 connections go beyond 610 m (2,000 ft).
    • IP connections can be routed worldwide. 
  9. The available COM ports listed in the COM Port drop-down menu are supplied to PC400 by the Windows Operating  System (OS). If there are no COM ports shown for selection, it most likely means that there are no COM ports registered with the Windows OS. This can be confirmed using the Windows Device Manager (Control Panel | Device Manager | Ports).

    Most modern laptops are not equipped with native RS-232 COM ports. In this situation, a USB-to-RS-232 adapter cable must be used to connect to the data logger. Even when the drivers for this device have been properly installed, the derived COM port will not be shown for selection until the cable is attached to the laptop.

  10. No, because it would not work. The SC32B is used to do the following:

    • Convert data logger logic levels (on the CS I/O port) to RS-232 levels 
    • Optically isolate the data logger from the RS-232 peripheral
