Technische Beschreibung

The CR6 measures almost any sensor with an electrical response, drives direct communications and telecommunications, reduces data to statistical values, performs calculations, and controls external devices. After measurements are made, data are stored in onboard, nonvolatile memory awaiting transfer to the computer. Because most applications do not require that every measurement be recorded, the program usually combines several measurements into computational or statistical summaries, such as averages and standard deviations.

Communication Options

The CR6-WIFI Option

The CR6-WIFI is the ideal solution for short-range wireless IP communications.

Using a Wi-Fi enabled device and our free LoggerLink Mobile App, you can wirelessly connect to the CR6-WIFI. The CR6-WIFI comes factory-configured as a Wi-Fi access point. Alternatively, the CR6-WIFI can be configured to join an existing Wi-Fi network with standard or Enterprise (EAP) security.

The CR6-RF407 Option

The CR6-RF407 is ideal for medium-range, license-free radio communications.

This 900 MHz, 250 mW frequency-hopping spread-spectrum radio option can join a high-speed "mesh topology" radio network of other data loggers using the included RF407 radio.

The CR6-RF412 Option

The CR6-RF412 is ideal for medium-range, license-free radio communications.

Designed primarily for unlicensed operation in Australia and New Zealand, this 922 GHz, 250 mW frequency-hopping spread-spectrum radio can join a high-speed "mesh topology" radio network of other data loggers using the included RF412 radio.

The CR6-RF422 Option

The CR6-RF422 is ideal for short- to medium-range, license-free radio communications.

Used in the EU, this 868 MHz, 25 mW radio option includes listen-before-talk (LBT) and adaptive-frequency-agility (AFA). It can join a high-speed "mesh topology" radio network of other data loggers using the included RF422 radio.

The CR6-RF452 Option

The CR6-RF452 is typically used for long-range, license-free radio communications.

With this internal 900 MHz, 1 W, frequency-hopping spread-spectrum radio option, the CR6-RF452 can be part of a "star topology" network where all RF traffic routes back through the master. It can work in a network with other devices using RF450 or RF451 radios. CR6-RF452s may be configured as master, repeater, or remote devices and can be located miles apart in harsh RF environments.

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

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 für

Number of FAQs related to CR6: 8

Alle anzeigenWenige anzeigen

  1. The CPI bus speed is adjustable in your CRBasic data logger program. Use the CPISpeed() instruction in your CRBasic program to adjust the CPI bus bandwidth to meet the following maximum combined (total) Ethernet cable lengths:

    • 1000 kB/s for maximum combined Ethernet cable lengths of 15.2 m (50.0 ft)
    • 500 kB/s for maximum combined Ethernet cable lengths of 61 m (200 ft)
    • 250 kB/s for maximum combined Ethernet cable lengths of 152.4 m (500 ft)
  2. The potential transformer and the current transformer provide differential outputs that have galvanic isolation from the voltage and current in the circuit they are measuring. However, there is no need to run the outputs of these transformers into differential inputs of the data logger and unnecessarily consume additional data logger channels. We conducted extensive testing for noise immunity, for inaccuracies from ground loops, and more before concluding that single-ended measurements in the ACPower() instruction have the same performance as differential measurements would provide. Please note that as a result of the galvanic isolation of the potential transformer and current transformer, the data logger ground is NOT connected to the ground of the circuit they are measuring.

    Said differently, you can connect differential outputs of a sensor to single-ended inputs of the data logger. However, doing so creates the possibility of poor common-mode noise rejection in the data logger and the possibility of introducing inaccuracies from ground loops between the sensor and the data logger. Note that in this application, the transformer isolation of the potential transformer and the current transformer eliminates these concerns.

    Simply connect one of the potential transformer secondary wires and one of the current transformer secondary wires to the data logger ground. Which wire in either case makes a difference, as the phase information allows the measurement of power flowing in either direction. If you measure negative real power when it should be positive, then reverse the secondary wires of the potential transformer where they connect to the data logger. Alternatively, you can reverse the secondary wires on the current transformer, but don't reverse both pairs of wires.

  3. 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."

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

     

  5. 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.
  6. 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.

  7. 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 Pin [Male] DTE).
    • Connect the modem to the RS-232/CPI port on the CR6 using cable pn 31056 (RS-232/CPI RJ45 to DB9 Socket [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.
