Detailed Description
This version of the CR800 is for OEMs. The OEM can purchase this product without a label or with a company label.
The CR800 is a smaller measurement and control data logger designed for stand-alone operation in harsh, remote environments. Each CR800 reads input from sensors, then transmits the data via a communication peripheral. Multiple CR800s can be configured as a network or units can be deployed individually.
The CR800's low power consumption allows it to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. This data logger suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
A typical field-based CR800 system consists of:
- CR800 Datalogger
- Power Supply
- Weatherproof Enclosure
- Communications Peripheral(s)
- Programming and Communications Software
- Sensors
The CR800 is compatible with our measurement and control devices, nearly every available sensor, and most of our communication devices; refer to the Compatibility tab for more information.

Compatibility
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)
