Direct connection of the CR800 to a PC is most conveniently done through the "Computer RS232" port (Figure OV1-3). Table OV1-2 gives a brief description of each "Computer RS232" pin. The Computer RS-232 port is a DCE device when connected to a PC with a serial cable.
CR800 and CR850 Overview OV1.3 Power Supply and AC Adapter The CR800 requires a separate 12 V power supply. The PS100 power supply has a 7 amp hour battery with built in charging regulator. Optional adapters for AC power are available. Charging power can also come from a 17-28 VDC input such as a solar panel. OV2. Memory and Operating Concepts OV2.1 Memory The CR800 has 2 MB Flash EEPROM that is used to store the Operating System. Another 128 K of Flash is used to store configuration settings.
CR800 and CR850 Overview OV2.3 Instruction Execution within the Datalogger The execution of instructions within the datalogger is accomplished using three separate task types: measurement, SDM, and processing. As it is named, the measurement task handles measuring the signals received on the datalogger’s wiring panel, as well as outputting signals for control of other devices. The measurement and control hardware is manipulated on a rigidly timed sequence.
CR800 and CR850 Overview is converted to a value determined by the processing included in the instruction, and then the datalogger proceeds to the next instruction. Because of this step-by-step instruction execution, conditional measurements are allowed in sequential mode. The exact time at which measurements are made may vary if other measurements or processing are made conditionally, if there is heavy communications activity or other interrupts. OV2.3.
CR800 and CR850 Overview conflicting use of measurement hardware. In this scheme the main scan has the highest priority and prevents other sequences from using measurement hardware until the main scan is completed (including processing). Other tasks, such as processing from other sequences and communications, can occur while the main sequence is running.
CR800 and CR850 Overview • Datalogger to datalogger communications – Special PakBus instructions simplify transferring data between dataloggers for distributed decision making or control. All devices that send or receive messages in a PakBus network must have a unique PakBus Address. The CR800 default PakBus address is 1. In a PakBus Network each datalogger must be set to a unique address before it is installed in the network. To communicate with the CR800, the PC software (e.g.
CR800 and CR850 Overview • Updates to DevConfig are available from Campbell Scientific's web site. These may be installed over top of older versions. OV3.1 Main DevConfig Screen The DevConfig window is divided into two main sections: the device selection panel on the left side and tabs on the right side. After choosing a device on the left, you will then have a list of the serial ports (COM1, COM2, etc.) installed on your PC.
CR800 and CR850 Overview OV3.2 Deployment Tab The Deployment Tab allows the user to configure the datalogger prior to deploying it. OV3.2.1 Datalogger Serial Number displays the CR800 serial number. This setting is set at the factory and cannot be edited. OS Version displays the operating system version that is in the CR800. Station Name displays the name that is set for this station. PakBus Address allows you to set the PakBus address of the datalogger. The allowable range is between 1 and 4094.

Security Password 2 When this level is set, data collection is unrestricted, requiring no security code. If the user enters the Security2 code, the datalogger clock can be changed and variables in the public table can be changed.
CR800 and CR850 Overview as neighbors on the port specified by Selected Port. As you select items in this list, the values of the Begin and End range controls will change to reflect the selected range. You can add multiple lists of neighbors on the same port. Begin and End Range are used to enter a range of addresses that can either be added to or removed from the neighbors list for the port specified by Selected Port.
CR800 and CR850 Overview OV3.2.3 Advanced Is Router allows you to control whether the datalogger will act as a PakBus router. PakBus Nodes Allocation Specifies the amount of memory that the CR800 Allocates for maintaining PakBus Routing information. This value represents roughly the maximum number of PakBus Nodes that the CR800 will be able to track in its routing tables.
CR800 and CR850 Overview OV3.3 Logger Control Tab The clock in the PC and the datalogger will be checked every second and the difference displayed. The System Clock Setting allows you to configure what offset, if any, should be used with respect to standard time (Local Daylight Time or UTC, Greenwich mean time). The value selected for this control will be remembered between sessions. Clicking the Set Clock Button will synchronize the station clock to the current computer system time.
CR800 and CR850 Overview OV3.4 Send OS Tab - Downloading an Operating System DevConfig can send operating systems to all Campbell Scientific devices with flash replaceable operating systems.

When you click the Start button, DevConfig offers a file open dialog box to prompt you for the operating system file (*.obj file).
CR800 and CR850 Overview OV3.5 Settings Editor Tab The CR800 has a number of properties, referred to as “settings”, some of which are specific to the PakBus protocol. PakBus is discussed in more detail in the PakBus Networking Guide available from the Campbell Scientific website (www.campbellsci.com). The Settings Editor tab provides access to most of the PakBus settings, however, the Deployment tab makes configuring some of these settings a bit easier.
CR800 and CR850 Overview Clicking the Revert to Defaults button on the Settings Editor will send a command to the device to revert to its factory default settings. The reverted values will not take effect until the final changes have been applied. This button will remain disabled if the device does not support the DevConfig protocol messages.
CR800 and CR850 Overview OV4. Quick Start Tutorial OV4.1 Software Products for the CR800 PC200W Starter Software supports a direct connection between the PC and the CR800, and includes Short Cut for Windows (Short Cut) for creating CR800 programs. PC200W provides basic tools for setting the datalogger’s clock, sending a program, monitoring sensors, and manually collecting and viewing data. CR800 support was added to PC200W in Version 3.0.
CR800 and CR850 Overview 2. The CRBasic Editor is a program editor used to create more complex CR800 programs. Short Cut generated programs can be imported into the CRBasic Editor for adding instructions, or for functionality not supported by Short Cut. For those users of CR10X dataloggers who are switching to CR800 dataloggers, the Transformer Utility can be used to convert a CR10X program to a CR800 program, which can be imported into the CRBasic Editor.
CR800 and CR850 Overview OV4.3 Setting the CR800 PakBus Address The CR800 default PakBus address is 1 (Section OV2.5).
