Overview

The CR6 measurement and control datalogger is a powerful core component for your data-acquisition system. We combined the best features of all our dataloggers and added faster communication, low power requirements, built in USB, compact size, and improved analog input accuracy and resolution. The CR6 also introduces our new universal (U) terminal, an ingenious way to allow virtually any sensor—analog, digital, or smart—to be connected to any U terminal. This is also our first multipurpose datalogger capable of doing static vibrating-wire measurements.

Compatibility

Sensors

The CR6 has 12 U terminals and four C terminals that are programmable for a variety of functions. This allows the CR6 to measure virtually any sensor, including voltage, resistive bridge, static vibrating wire, pulse, switch closure, SDI-12, and serial RS-232/RS-485.

Measurement & Control Peripherals

The CR6 includes an interface that allows it to connect directly with our CDM device (the SC-CPI interface is not required). The CR6 is also compatible with all of our contemporary SDMs, multiplexers, terminal input modules, and relays. 

Communications

The CR6 has an on-board 10/100baseT port for Ethernet communication, a USB port for communication with a PC, and a slot to store data on a microSD card. Compatible telemetry devices include our multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, High Data Rate GOES, and Meteosat). Data can be viewed on the CR1000KD Keyboard Display, CD100 Mountable Display with Keyboard, or an iOS or Android device (requires LoggerLink).

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 or charge regulator, is used to charge a 12 Vdc battery, such as our BP7, BP12 or BP24.
  • 12 Vdc battery or other reliable 12 Vdc source
  • Chg 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 SW12 or 12V Power Output terminals)  

Software

CRBasic, the CR6's full programming language, supports simple or complex programming and many on-board data reduction processes. Compatible software includes:

  • LoggerNet (version 4.3 or higher)
  • DevConfig (version 2.10 or higher)
  • PC400 (version 4.3 or higher)
  • PC200W (version 4.3 or higher)
  • Short Cut (version 3.1 or higher)
  • CRBasic (version 3.5 or higher)
  • LoggerLink (version 1.3 or higher)
  • RTDAQ (version 1.2 or higher)
  • LNDB (version 1.2 or higher)

Downloads

CR6 OS v.6.01 (5.93 MB) 10-02-2017

Execution of this download installs the CR6 Operating System and Compiler on your computer.  It also updates the CR6 support files for the CRBasic Editor. 

Note: Upgrading the Operating System will reset all the CR6’s settings back to the factory defaults.  Sending this OS remotely is not recommended.  To restore settings after the update, it is recommended that a backup be made of the current logger settings or take programmatic measures to ensure your settings can be restored. This can be done using the DevConfig backup utility or CRBasic instruction SetSetting.

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

 

Related FAQs

Number of FAQs related to CR6: 2

  1. 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.
  2. 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.
