概览
CR800数据采集器是小型的研究级精度的数据采集器，设计用于严酷的远程环境中独立工作。倾向支持只测量少数几个传感器的小型应用。每个CR800读取传感器的读数，再通过通讯外设传送数据；可兼容大多数传感器和通讯设备。多个CR800可以被设置成数据采集器网络；或者，众多CR800单元也可被逐个配置。
另一种数据采集器，CR850与CR800类似，但多了一体式的键盘显示器，可实施现场控制。

技术说明
CR800包含封装在塑料壳内的测量控制模块和一体式接线面板。CR800使用外部的键盘显示器和供电电源，极低的功耗使得CR800只需要使用小容量的可充电电池和太阳能板组合供电，从而不需要交流电源。为了减小非精确测量的可能性，当主电源低于 9.6 V时，CR800会暂停工作。
内部的操作系统包括数据采集器编程所需的测量、处理、输出指令。编程语言为CRBasic，使用类BASIC语法。测量指令包括：电桥设置、电压输出、热电偶、脉冲/频率信号。处理指令包括：代数运算、统计及用于现场处理的超越函数。输出指令按时间段处理数据，或控制外部设备。

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.

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.
Device Configuration Utility v.2.29.01 (54 MB) 15-08-2024
A software utility used to download operating systems and set up Campbell Scientific hardware. Also will update PakBus Graph and the Network Planner if they have been installed previously by another Campbell Scientific software package.
Supported Operating Systems:
Windows 11 or 10 (Both 32 and 64 bit)

-
The 5 V terminal is regulated and remains near 5 Vdc (±4%) as long as the CR800 supply voltage remains above 9.6 Vdc. Measurement of the output from 5 V (by means of jumpering to an analog input on the same CR800) enables an accurate bridge measurement if the 5 V terminal must be used for excitation.
-
The SC115 (2 GB) is the only device capable of extending the memory of the CR800 or CR850.
-
LoggerNet is available in a Linux version (LNLINUX).
-
Yes. EX and VX are synonymous and refer to voltage excitation.
-
Use the CURS100 device or a precision 100 ohm resistor to make 4 to 20 mA measurements.
-
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.
-
No. The setup is identical.
-
Yes. For instructions, refer to the operator’s manual.
-
Yes. The CR800 and CR850 are compatible with exactly the same options as the CR1000 but with a lower channel count.
