With several channel types, the CR350 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. CR350 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 CR350 also supports true RS-232 and RS-485 on COM2 and COM3, along with a dedicated RS-232 DB9 port.
The CR350 is compatible with low current and voltage solid-state relays but not with SDM or CDM devices.
The CR350 series is compatible with CRBasic (version 3.6 or higher).
An ENC10/12 or ENC12/14 enclosure is adequate for most CR350-based systems.
The CR350 can communicate with a PC directly via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters (HDR GOES, Argos, Meteosat, Iridium, and Inmarsat). Data can be viewed on an iOS or Android device (requires our free LoggerLink app), CD295 DataView II Display, or other third-party devices.

The CR350 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:
This download is for the CR350 datalogger. 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.
