Enclosures

The CR6 and its power supply can be housed in any of our standard enclosures.

Power

The CR6 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (CHG, BAT, or USB) to operate in one of the following four modes:

  • UPS (recommended)—A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter is used to charge a 12 Vdc battery, such as our BP7, BP12, or BP24.
  • 12 Vdc battery or other reliable 12 Vdc source
  • Charge only—dc power supply (16 to 32 Vdc)
  • USB—Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the SW12 switched battery terminals or the 12V power output terminal)

Software

CRBasic, the CR6's full programming language, supports simple or complex programming and many on-board data reduction processes. The CR6 is compatible with CRBasic (version 3.5 or higher).

Downloads

CR6 OS v.9.02 (6.87 MB) 22-04-2019

This download is for the CR6 datalogger. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files. 

Why Update? This OS contains new support for the Campbell Scientific CELL2xx external modems and bug fixes.  With this OS update it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.  

Note: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.

CPI Calculator v.1.0 (2.49 MB) 06-07-2016

The CPI Calculator is a downloadable Microsoft Excel spreadsheet used to estimate the usage and capacity of a CPI network.  The calculator provides an overview on CPI devices including the CDM-A108, CDM-A116, CDM-VW300, CDM-VW305, and the CSAT3B.  The calculator can also estimate the measurement speed of the CDM-A108 and CDM-A116 based on the number of channels and measurement parameters.

 

The CPI Calculator is an estimation tool and will help you better understand and design CPI networks by considering the following:

  1. What is the capability of each CDM or CPI device
  2. What is the CPI network capacity
  3. How much of the CPI capacity are the CDMs or CPI devices using

 

FAQs for

Number of FAQs related to CR6: 6

Expand AllCollapse All

  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.

  2. When idle, the CR1000, CR6, and CR1000X consume less than 1 mA @ 12Vdc. Similar to the CR6, the CR1000X has a much faster processor that requires more power when up and running. As such, there will be higher current draws during active measurements, serial communications, or when plugged into a PC via USB or Ethernet.

    It may be helpful to think of the CR6 and CR1000X as being built on the same "platform."

  3. The CR6 has true RS-232 levels on the RJ45 (CPI), and the data logger can be programmed for RS-232 levels on C1-C2 and C3-C4.

     

  4. Campbell Scientific sells, and embeds in their products, microSD cards that have single-level cell (SLC) memory. In contrast, many electronics retailers sell microSD cards that have multi-level cell (MLC) memory. The difference between these two types of memory is significant.

    • The SLC microSD cards from Campbell Scientific are better suited for industrial and environmental applications where wide operating temperatures, low power consumption, and longevity are very important. Most SLC memory cards are designed with industrial applications in mind and, therefore, often have additional perks such as enhanced protection from ESD (electrostatic discharge) and mechanical damage.
    • The MLC microSD cards commonly available at electronics retailers are less expensive, but they are generally not well suited for the majority of applications in which Campbell Scientific data acquisition products are used.
  5. Yes. The communications tasks run independently of each other, and multiple computers can be connected at the same time. If PakBus is being used to communicate, ensure that the computers are using different PakBus addresses to communicate to the data logger.

  6. The serial modem can be connected to a CR6 using any of the following methods:

    • Connect the modem to the RS-232/CPI port on the CR6 using cable pn 31055 (RS-232/CPI RJ45 to DB9 Male DTE).
    • Connect the modem to the RS-232/CPI port on the CR6 using cable pn 31056 (RS-232/CPI RJ45 to DB9 Female DCE).
    • Connect the modem to a C or U terminal pair on the CR6, where the pair has been configured for serial I/O.
    • Connect the modem to the CS I/O port on the CR6 using an SC105.
