CR23X Micrologger® for Data Acquisition
Services Available
Repair Yes
Calibration Yes
Free Support Yes

Resumen

The CR23X Micrologger® was a portable, self-contained package that could store over 1,000,000 data points. It consisted of measurement and control electronics, communication ports, keyboard, 2-line alphanumeric display, power supply, and a battery-backed clock. The CR23X measured most sensor types directly, communicated via modems, reduced data, controlled external devices, and stored both data and programs in either non-volatile Flash memory or battery-backed SRAM.

Descripción técnica

The CR23X is a self-contained, rugged datalogger that can measure most sensor types directly, communicate via modems, reduce data, control external devices, and store both data and programs in either non-volatile Flash memory or battery-backed SRAM.

The CR23X has an integral, 2-line, alphanumeric display and power supply. A battery-backed, real-time clock and 2M of nonvolatile data storage is included. The CR23Xs are available with a sealed rechargeable battery base, an alkaline base, or in a low-profile version without batteries.

  1. Look for a stamp on top of the battery. The stamp should 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.

    To evaluate the condition of the battery:

    1. Charge the battery.
    2. Let the battery sit for a couple of hours.
    3. Measure the open circuit voltage to get an estimated indication of condition.
  2. 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.

  3. A practical maximum is to connect one multiplexer per every two control terminals on the datalogger. 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.

  4. No. The CR23X program must be translated into CRBasic using the Translator software or by hand.
  5. E08 errors are occasionally created by voltage surges or transient voltages. Section 3.9 of the CR23X manual explains in greater detail what a watchdog is and possible causes.  If these are happening frequently, it is likely an issue with the system  that needs to be resolved. The first step in this resolution process would be to check the system power (inputs and outputs) and verify it is within the expected tolerances as outlined in the Specifications page (OV-23) of the CR23X Micrologger Operator's Manual

  6. 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.
