Ideal for small applications
View the QuickStart Guide
Overview
The CR310 is a multi-purpose, compact, low-cost measurement and control data logger that includes an integrated 10/100 Ethernet port and removable terminal connectors. This entry-level data logger, with its rich instruction set, can measure most hydrological, meteorological, environmental, and industrial sensors. It will concentrate data, making it available over varied networks and deliver it using your preferred protocol. The CR310 also performs automated on-site or remote decision making for control and M2M communications. The CR310 is ideal for small applications requiring long-term, remote monitoring and control.
The primary differences between the CR300 and CR310 are that the CR310 offers removable connectors and a 10/100 Ethernet connection.
The CR310 has multiple radio options that are suitable for different regions:
- CR310-RF407: US and Canada
- CR310-RF412: Australia and New Zealand
- CR310-RF422: Europe
- CR310-RF427: Brazil
Note: Campbell Scientific does not recommend the CR310 for use as a PakBus router in networks with more than 50 devices. Large arrays or string variables may also reach memory limits. For such applications, a CR1000X Measurement and Control Datalogger is recommended.

Additional Compatibility Information
Measurement & Control Peripherals
The CR310 is typically not used with measurement and control peripherals because of its limited number of control ports. It is also compatible with low on current and voltage solid-state relays.
The CR310 is not compatible with SDM or CDM devices.
Sensors
With several channel types, the CR310 is compatible with nearly every available sensor. This includes analog output voltage (0 to 2.5 V) and current (0 to 20 mA or 4 to 20 mA) sensors, thermistors, and RTDs to name a few. It is also compatible with pulse or frequency output sensors such as anemometers, rain gauges, and flow meters. CR310 dataloggers are not capable of applying reverse excitation, and they cannot be used with some conductivity or soil matric potential sensors.
SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR310 does not directly support RS-485 sensors.
Communications
The CR310 can communicate with a PC via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters. Data can be viewed on an iOS device, an Android device, or CD295 DataView II Display. To use an iOS or Android device, go to the Apple Store or Google Play and download our free LoggerLink Mobile Apps.

Software
The CR300 series is compatible with CRBasic (version 3.6 or higher).
Power
The CR310 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (Chg, Bat, or USB) to operate in one of the following four modes:
- UPS (recommended) - A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter (29796) is used to charge a 12 Vdc battery, such as our BP7 or BP12.
- 12 Vdc battery or other reliable 12 Vdc source
- Chg only - DC power supply (16 to 32 Vdc)
- USB - Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the switched battery terminal SW12)
Enclosures
An ENC10/12 or ENC12/14 enclosure is adequate for most CR310-based systems.

CR300 Series OS v.11.01 (4.96MB) 23-07-2024
This download is for the CR300 series of dataloggers including all CR300 and CR310 models. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files.
Why Update? This OS resolves several bugs found in the previous OS. See the revision history for a complete list. With this OS update, it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.
Note/Warning: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.
