Additional Compatibility Information

Sensors

With several channel types, the CR800 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 CR800's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement and Control Peripherals

The CR800 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

The CR800 communicates with a PC via direct connect, NL201 Ethernet Interface, multidrop modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat.

Data can be viewed on the CR1000KD Keyboard Display, CD100 Mountable Display with Keypad, user-supplied iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

The SC115 is the only compatible external data storage device. The CR800 does not have a peripheral port and is therefore not compatible with the CFM100, NL115, or NL120.

Enclosures

The CR800 and its power supply can be housed in any of our standard enclosures. 

Power

Any 12 Vdc source can power the CR800 datalogger. Power supplies commonly used with the CR800 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 A h rating at 20°C.

Both the PS150 and PS200 consist of a sealed rechargeable 7 A h battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS150 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.

Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 A h, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).

Software

CRBasic, the CR800's full programming language, supports simple or complex programming and many onboard data reduction processes.

Downloads

CR800 OS v.32.07 (4.41 MB) 15-05-2024

Execution of this download installs the CR800 Operating System and Compiler on your computer.  It also updates the CR800 support files for the CRBasic Editor.  

Note: This OS has crossed the 2 Meg CR800 size limit for remote download.  The OS must be downloaded to the 2 Meg CR800 via direct connect with the Device Configuration Utility.  All OS download methods are supported by the 4 Meg CR800.

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.

  1. How can I troubleshoot FTP communications between my data logger and a server?

    Refer to the FTP Troubleshooting application note for help. 

  2. Why are single-ended measurements used in the ACPower() instruction in CRBasic when the outputs of the potential transformer and current transformer are inherently differential?

    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. Can the CR800 be programmed through either a mountable or portable keyboard display?
    Yes, but it is difficult and time consuming. The display is best used to make small changes in an existing program already installed in the datalogger.
  4.  Comment établir une connection avec un système d’acquisition de données à travers le port de série RS-232 (Pour le CR800, CR1000X et CR3000)

    1. Connectez l'alimentation électrique au système d’acquisition de données

    • Assurez-vous que le câble  est branché dans “Power In”
    • Pour tester la puissance dans un système d’acquisition qui n'a pas d'ecran, utilisez un multimètre pour tester. (Si l'alimentation est en cours, vous devriez lire environ 12 Volts)

    2. Télécharger le pilote

    • Si vous avez acquis le système d’acquisition de données de chez Campbell Scientific, un CD a été fourni avec le logiciel du pilote.
    • Si vous n'avez pas le CD,  Vous pouvez télécharger la dernière version du pilote a www.campbellsci.ca/l17394.
    • Si vous avez acquis le système d’acquisition de données d'un autre fabricant,  Vous devez télécharger la dernière version du pilote de leur site Web.

     3. Ouvrez le Gestionnaire de périphériques

    • Dans le menu Démarrer de Windows, accédez -> “Device Manager” -> “Ports”
    • Si le programme “Device Manager” est bloquée, vous avez besoin d’obtenir les autorisations nécessaires de l'administrateur informatique.
    • Si l’icône ci-dessous apparaît, cela signifie que le pilote n’été pas installée correctement et doit être réinstallé.

       

           
    4. Tester le cable
    • Pour s'assurer que le câble fonctionne correctement, connectez l'extrémité de ce câble dans un port USB de votre ordinateur.
    • Si “USB Serial Port” apparaît sous l’onglet “Ports” mentionné ci-dessus, le câble fonctionne correctement.

  5. Is the CR800 or CR850 compatible with an Iridium satellite transceiver?
    Yes. Many customers use the Iridium satellite transceiver.
  6. Can a CR800 poll a CR5000 to get low-frequency data via RF?

    No.

  7. Is there any required calibration for the CR800 or CR850?
    Calibration is recommended every two years.
  8. Does the data from the CR800 or CR850 need to be downloaded before changing the 12 Vdc battery?
    No, unless the internal lithium battery is below 2.7 Vdc. The lithium battery helps preserve the data, program, and clock setting when the 12 Vdc battery is removed.
  9. Does the CR800 or CR850 work with a 2 kHz (maximum) burst mode for the VoltDiff() instruction like the CR1000 does?

    Yes. The CR800 and CR850 are compatible with exactly the same options as the CR1000 but with a lower channel count.

  10. Is it possible to connect a fiber optic line directly to the RS-232 interface on the CR800 or the CR850?
    No. A device is needed that can convert fiber optic to RS-232. Many customers have used products from B&B Electronics for this purpose.
