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.

Frequently Asked Questions

-
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.
-
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.
-
If small amounts of data are transferred per transmission, it will not be a problem. Larger amounts of data can overrun buffers in the modem, causing lost data. In that situation, lower the baud rate on the data logger to avoid the issue.
-
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.
-
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
-
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.
-
A free program generator for all Campbell Scientific data loggers is Short Cut for Windows (SCWin). Short Cut can be used to create programs in many situations where Campbell Scientific equipment is used.
In situations where program requirements are too complex or specialized for Short Cut, programs can be written in any text editor that can edit and save plain ASCII text. However, creating an error-free program would be very difficult. The CRBasic Editor that comes with PC400 and LoggerNet provides a programming environment with procedure templates, integrated help, programming examples, the ability to test compile the program before sending it, and many other features that can be very helpful when developing a program.
-
Yes. All Campbell Scientific data loggers currently have nonvolatile memory. Nonvolatile memory was added to the CR10X in 1996. All data logger models introduced since then have included nonvolatile memory.
Nonvolatile memory is reliant on the 3 V lithium battery inside the data logger. As long as this internal battery has a charge above 3 V, no data should be lost if the data logger loses power.
-
Possibly. If a voltage greater than 16 Vdc is applied to the wiring panel, it could damage the input and result in inaccurate measurements.
Additionally, in some cases the sensors can be damaged if they are wired to the wrong channels. If a sensor, wired into an analog input channel, has an output of more than 5 Vdc, measurements on adjacent analog input channels may be upset. For example, the maximum full-scale range on the CR5000 is ± 5Vdc.
-
Many of our more recent data loggers have a Micro B USB port. Simply use a Type A to Micro B, male-to-male cable. Although any USB cable, with the correct connectors and drivers, should work, there is a better chance of success using a cable supplied by Campbell Scientific.
For data loggers with an RS-232 port, only a serial or USB to RS-232 cable (sometimes called a USB-to-serial-adapter cable) is needed. Although any USB to RS-232 cable should work with the appropriate drivers, there is a better chance of success using the USB to RS-232 cables sold by Campbell Scientific.
There are several options for data loggers that don’t have an RS-232 port but have a CSI/O port:
- Use the SC-USB connector/interface instead of the SC32B.
- Use the SC32B with a 17394, USB-to-9-pin male RS-232 cable.
- Use a user-supplied USB interface with the SC32B.
For data loggers with a CSI/O and RS-232 or USB port, it is not necessary to use the SC32B unless there is another device connected to the RS-232 port or there are concerns about low-level noise from a permanently connected, ac-powered computer.
