Overview
The CR295X is a small, low-cost data logger that reads input from one or two sensors, then transmits the data using the GOES satellite transmitter. Multiple CR295Xs can be configured as a network, or units can be deployed individually. CRBasic, its full programming language, supports simple or complex programming and many onboard data reduction processes. It supports stand-alone operation in harsh, remote environments.

Detailed Description
The CR295X includes an additional RS-232 serial port that allows communications with the TX320, TX312, or SAT HDR GOES satellite transmitter. It has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.
The CR295X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples. (Refer to the Compatibility information on the web page for compatible sensors, peripherals, and software.) Recalibration services are not offered for the CR295X dataloggers.

Additional Compatibility Information
Communications
The CR295X is compatible with our TX320, TX312 (retired), and SAT HDR GOES (retired) satellite transmitters.
The CR295X can communicate with a PC via direct connect, NL201 Network Link Interface, NL240 Wi-Fi Network Link, MD485 multidrop modem, and digital cellular modems. Data can be viewed on an iOS device, an Android device, CD295 DataView II Display, or a user-supplied PDA. To use an iOS or Android device, go to the Apple Store or Google Play and download our LoggerLink Mobile Apps free of charge. User-supplied PDAs require either PConnect or PConnectCE software.
Measurement & Control Peripherals
Campbell Scientific’s SDM devices and multiplexers are not supported.
Power Supplies
Typical power supply is a BP12 12 Ahr or BP24 24 Ahr battery, CH100 or CH200 regulator, and an SP10 or SP20 solar panel. The CR295X includes a cable for connecting it with the satellite transmitter and power supply.
Enclosures
An ENC16/18 enclosure can house the CR295X logger, satellite transmitter, and power supply; smaller enclosures cannot house the power supply required for GOES communications. Hardware is included with the data logger for mounting to an enclosure backplate.
Sensors
The CR295X can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. It cannot make differential measurements and is not compatible with the freezing-rain/ice, fuel moisture/temperature, geographic position, present weather, soil heat flux, soil matric water potential, and strain sensors listed on our price lists.

Not directly. If the CS15-L is connected to a CR200(X) datalogger, the data logger can take the ac measurement and control a solid-state relay based on some threshold within the data logger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the data logger can trigger it with a small 5 Vdc mA signal.) For more information, see the “Measurement and Control Peripherals” section of the operator’s manual.
-
Yes. The simplest method is to use conditional program statements that execute most of the code based on time. For example, the data could be scheduled to log at 6 a.m. and finish at 8 p.m. using CRBasic instructions such as IfTime(). Another option is to use an IfThen/EndIf construction that does a logical test of light-level measurements based on a light sensor. An additional option is to use calculated sunrise and sunset times along with a combination of RealTime() and Case instructions.
For more information, see the “Decisions, Decisions, Decisions…” article.

Current data loggers compatible with the BMP5 Direct SDK are the CR200X-series, CR1000, CR3000, CR800, and CR850.
Retired compatible data loggers include the CR10X-PB, CR23X-PB, and CR510-PB. These data loggers must have the optional PakBus operating system installed, which is available on the Downloads page of our website.
-
The maximum cable length depends on the interface being used.
- RS-232 connections will reach 15 m (50 ft).
- RS-485 connections go beyond 610 m (2,000 ft).
- IP connections can be routed worldwide.
-
Technically, the SRM-5A is compatible with the CR200X-series dataloggers, but it is more complicated to use it with these data loggers. To use a SRM-5A with a CR200X-series datalogger, the SRM-5A must be in the DTE position on the station modem. In addition, user-supplied adapters and gender changers are needed to complete the connections between the SRM-5A and the RS-232 port of the data logger. Contact Campbell Scientific for more information.
-
No, because it would not work. The SC32B is used to do the following:
- Convert data logger logic levels (on the CS I/O port) to RS-232 levels
- Optically isolate the data logger from the RS-232 peripheral
-
Some Campbell Scientific sensors with an RS-232 output are supported in Short Cut. Because of the large variety of serial data formats, other sensors require creating a program in the CRBasic Editor. CRBasic Editor is included in several of the purchased software packages, such as LoggerNet. For more information, see the “Interfacing Serial Sensors with Campbell Scientific Dataloggers” application note.
Note: The CR200X-series dataloggers have very limited serial capabilities.
-
The internal battery is not rechargeable. In the case of low internal battery voltage, data will only be maintained as long as a power supply is connected. Collect all data from the data logger before disconnecting the power.
The battery, a 15598, is not user replaceable. The data logger should be returned to Campbell Scientific to have the battery replaced. To request a return material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.
-
The CRBasic Editor Help contains example program code for all instructions in the data logger. Look for the Example link at the top of each instruction topic. The CRBasic Help Tutorial demonstrates how to access this and other online CRBasic Editor Help files.
Also, many programming examples can be found in the data logger and sensor manuals that are available on the Campbell Scientific website.
-
A data logger can be programmed to initiate data transfer by using the SendVariables() or ModemCallback() instruction in CRBasic.
NOTE: These instructions are not supported in the CR200X operating system.
