Descripción técnica

Housed in a portable, self-contained package, the CR3000 Micrologger consists of measurement and control electronics, communication ports, 16-character keyboard, display, power supply, and carrying handle. The integrated display shows 8 lines x 21 characters (64 x 128 pixels).

The CR3000 has a choice of three power-supply base options (alkaline, rechargeable, or no battery). Low power consumption allows the Micrologger to operate for extended time periods on its battery recharged with a solar panel—eliminating the need for AC power. It suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The on-board operating system includes measurement, processing, and output instructions for programming the datalogger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.

Additional Compatibility Information

Sensors

With several channel types, the CR3000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR3000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement & Control Peripherals

The CR3000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

The CR3000 communicates with a PC via direct connect, Ethernet interfaces, multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat).

Data can be viewed on its onboard keyboard display, user-supplied iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

Compatible external data storage devices are the CFM100, NL115, and SC115.

Enclosures

The CR3000 can be housed in an ENC12/14, ENC14/16, ENC16/18, ENC24/30, or ENC24/30S enclosure.

Power Supplies

The CR3000 is typically powered by its on-board alkaline or rechargeable power supply (see Ordering Info). When the rechargeable power supply is used, its internal 7 A h sealed rechargeable battery needs be charged via a vehicle (requires the DCDC18R), solar panel, or ac wall charger.

The CR3000 can also come with a low-profile base that requires a user-supplied dc source. It is preferred when the system’s power consumption needs a larger capacity battery or when it’s advantageous for the Micrologger to be thinner and lighter.

Software

CRBasic, the CR3000's full programming language,  supports simple or complex programming and many on-board data reduction processes. Compatible software includes:

  • Short Cut
  • PC200W
  • PC400 (version 1.3 or higher)
  • LoggerNet (version 3.2 or higher)
  • RTDAQ (version 1.0 or higher)
  • PConnect (version 3.2 or higher)
  • PConnectCE (version 2.1 or higher)
  • VisualWeather (version 2.0 or higher)

Downloads

CR3000 OS v.32.03 (4.91 MB) 13-08-2018

Execution of this download installs the CR3000 Operating System and Compiler on your computer.  It also updates the CR3000 support files for the CRBasic Editor.  

Note: The Device Configuration Utility is used to upload the included operating system to the datalogger.

Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive.  This is due to a change in the format of the file system from FAT16 to FAT32.  In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32.  Any programs stored and running from the CPU drive will be lost.  It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.).  In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

Number of FAQs related to CR3000: 9

Expand AllCollapse All

  1. Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:

    • YY is the year.
    • MM is the month.
    • DD is the day.
    • XX is the manufacturing plant.

    This indicates the age of the battery.

  2. 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.

  3. Yes. We have created a software application, Transformer, to help migrate CR23X program files to CR3000 program files. Transformer is available within LoggerNet 3.2 and higher.

    • From the Windows Start Menu, navigate to LoggerNet3.0 | Utilities | Transformer.
    • In LoggerNet 4.x, from the main LoggerNet window, navigate to Program | Transformer.

    Transformer uses a .csi or .dld file created in Edlog to generate CRBasic code for a CR3000. A side-by-side comparison of the two programs is provided along with an action log that highlights parts of the program that may need attention or additional editing in CRBasic.

  4. Sending a serial string out one of the data logger COM ports requires at least two instructions. Generally, the SerialOpen() instruction is used to set the characteristics of the communications port, such as baud rate and error detection (for example, 115.2k, N, 8, 1). The instructions SerialOut() or SerialOutBlock() can be used to transmit a specified string. See the CRBasic Editor Help for examples of programs using each of these instructions.

  5. The CRBasic Editor Help contains example program code for all instructions in the data logger. Look for the Example link at the top of each instruction topic. The CRBasic Help Tutorial demonstrates how to access this and other online CRBasic Editor Help files.

    Also, many programming examples can be found in the data logger and sensor manuals that are available on the Campbell Scientific website.

  6. A free program generator for all Campbell Scientific data loggers is Short Cut for Windows (SCWin). Short Cut can be used to create programs in many situations where Campbell Scientific equipment is used. The Campbell Scientific YouTube channel has a two-part series on using Short Cut.

    In situations where program requirements are too complex or specialized for Short Cut, programs can be written in any text editor that can edit and save plain ASCII text. However, creating an error-free program would be very difficult. The CRBasic Editor that comes with PC400 and LoggerNet provides a programming environment with procedure templates, integrated help, programming examples, the ability to test compile the program before sending it, and many other features that can be very helpful when developing a program.

  7. Not the same, but similar. The SDM-SIO4 provides RS-232 voltage levels; the CR1000 control ports provide 0 to 5 V only. Both usually work with all sensors, and both devices are compatible with RS-232 and TTL logic. The CR1000 is easier to set up and program for serial input. The SDM-SIO1 is a preferred alternative to the SDM-SIO4.

    When compared to the CR10X, the CR1000 can handle strings as a specific data type. It also has more integrated serial interfaces including the following:

    • Four control port pairs—COM1 (C1 TX / C2 RX) through COM4 (C7 TX / C8 RX)
    • RS-232 port
    • CS I/O port for connection to CS I/O peripherals

    The serial I/O capabilities of the CR1000/CR3000 are similar to, and faster than, the SDM-SIO4 capabilities on a CR10X or CR23X. SDM devices are addressable and are connected to a datalogger on C1 through C3. Therefore, one benefit of using multiple SDM devices on a CR1000 datalogger is that only three control ports are used.

  8. Yes. For example, the NL115 allows the CR1000 to communicate over a local network or a dedicated Internet connection via TCP/IP.
