CR205 Datalogger with 915-MHz Spread-Spectrum Radio

Overview

In September 2005, the CR205 Datalogger was replaced by the CR206 Datalogger. The CR206 has improved communication capability. The CR205 can be used within a CR206(X) network, but the CR206(X) needs to be in the transparent mode. Contact one of our application engineers for details.

Benefits and Features

  • Ideal where only a few sensors will be measured
  • On-board 12 Vdc lead acid battery charger
  • Stores 32,000 data points (nonvolatile)
  • Data format is table-based

Compatibility

Communications

The CR205's internal spread spectrum radio can transmit data to other CR205 loggers or RF400 radios. It can also communicate with CR206(X) loggers, RF401 radios, or RF430 radios if they are set to the transparent mode. Certain CR205 settings must match the radio's settings for communications between the datalogger and radio to be successful. The factory default settings of these devices might not match; therefore, they may need to be reconfigured before communications can take place. 

The CR205 can communicate with a PC via direct connect, NL100 Ethernet interface, MD485 multidrop modem, and digital cellular modems. Data can be viewed on the CD295 DataView II display, Archer-PCon Field PC, or a user-supplied PDA (PConnect or PConnectCE software required).

Measurement & Control Peripherals

The CR205 is not compatible with SDM devices and multiplexers.

Sensors

The CR205 can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. It cannot make differential measurements and is not compatible with the freezing-rain/ice, fuel moisture/temperature, geographic position, present weather, soil heat flux, soil matric water potential, and strain sensors listed on our price lists.

Enclosures

Applications with minimal power requirements can use the ENC200 enclosure to house the datalogger and the #16869 sealed rechargeable battery. The ENC200 cannot house a barometer or a battery that is larger than the #16869. However, an ENC10/12 or ENC12/14 enclosure is adequate for most CR205-based systems.

Power Supplies

The CR205 uses an external power supply and has a built-in regulator. When connected to the on-board charging circuit, the sealed rechargeable battery should be 7 Ahr or smaller. Using larger batteries with the datalogger's built-in charger may result in excessive PC board heating. This is especially a concern when the battery is deeply discharged or failing with a shorted cell. Campbell Scientific also recommends that solar panels be 10 W or less and wall chargers be 1 A or smaller.

Software

The CR205 is compatible with the following software packages:

  • Short Cut
  • PC200W
  • PC400 (version 1.0 or higher)
  • LoggerNet (version 2.1 or higher)
  • PConnect (version 3.0 or higher)
  • PConnectCE (version 2.0 or higher)
  • VisualWeather (version 2 or higher)

Frequently Asked Questions

Number of FAQs related to CR205: 3

Expand AllCollapse All

  1. The CR200X-series and the retired CR200-series dataloggers are NOT compatible with SDMs or multiplexers. If more channels are needed or may be needed in the future, consider purchasing a CR800, CR850, or CR1000 instead.

  2. The CR200-series datalogger is unique in that it does not have an on-board program compiler like other Campbell Scientific dataloggers. This means that the CRBasic file (*.cr2) must be compiled on the computer first, and then the compiled binary file (*.bin) must be sent to the datalogger. When a program is created in CRBasic, the last step is to compile the file and, therefore, create the program BIN file.

    It is very important that the compiler used to generate the BIN file match the operating system version in the datalogger. If a BIN file is sent to the datalogger and the compiled version does not match the current OS, the program send will fail and an "Incorrect OS Version" message will be displayed. 

    To help avoid issues with OS version mismatch, if the CR2 file is chosen as the file to download to the datalogger, LoggerNet version 2.1b and greater will first query the datalogger for its OS version and then attempt to find the matching compiler in the LoggerNet program files directory (by default, this is C:\Program Files\Campbellsci\LoggerNet). If the matching compiler exists, LoggerNet will compile the file and send that file to the datalogger. Note that if the *.bin file is chosen, LoggerNet will not compile the file before sending it.

    The software CD that is shipped with each CR200-series datalogger contains the appropriate compiler for the datalogger OS. Copy this file into the LoggerNet program files directory so that it is available for use by LoggerNet. In CRBasic, select this file as the compiler to be used when compiling CR2 files from the Options | Supported Loggers menu item.

  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.
