CR800为较小尺寸的测量和控制数据采集器，可在严酷的远程环境中独立工作。每个CR800读取来自传感器的输入信号，再通过通讯外设传送数据。多个CR800可被设置成一个测量控制网络，或者每台CR800可被设置成独立工作。
CR800的功耗极低，只需可充电电池加上太阳能板的组合就可持续工作，不需要交流电源。当供电电压降至9.6 V以下时，CR800会暂停工作，减少不精确测量的可能性。
典型的野外CR800系统包括：
- CR800数据采集器
- 供电电源
- 耐候机箱
- 通讯外设
- 编程和通讯软件
- 传感器
CR800兼容我们的测量控制设备，几乎每个可用的传感器，以及我们大多数的通讯设备；请参考兼容性标签以查找更多信息。

兼容性
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 & Control Peripherals
The CR800 is compatible with all of our contemporary SDMs, multiplexers, vibrating wire interfaces, terminal input modules, and relays.
Communications
The CR800 communicates with a PC via direct connect, NL100 Ethernet Interface, multidrop modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, High Data Rate GOES, and Meteosat). Data can be viewed on the CR1000KD Keyboard Display, CD295 DataView II Display, Archer-PCon Field PC, 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 an ENC12/14, ENC14/16, or ENC16/18 enclosure.
Power
Any 12-Vdc source can power the CR800 datalogger; a PS100 or BPALK is typically used. The PS100 provides a 7-Ahr sealed rechargeable battery that should be connected to a charging source (either a wall charger or solar panel). The BPALK consists of eight non-rechargeable D-cell alkaline batteries with a 7.5-Ahr rating at 20°C.
Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 Ahrs, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 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. Compatible software includes:
- Short Cut
- PC200W
- PC400 (version 1.4 or higher)
- LoggerNet (version 3.3 or higher)
- RTDAQ
- PConnect (version 3.3 or higher)
- PConnectCE (version 2.2 or higher)
- VisualWeather (version 2 or higher)
