Technical Description
The CR6 is the only monitoring platform currently available that operates as an edge device and gateway with connectivity, provides an industry standard for rugged design, has universal sensor compatibility and communication options, and includes VSPECT for vibrating wire measurements.
Edge and Gateway Device
The variability and site-specific challenges and constraints that exist in robust monitoring networks typically result in a wide array of devices to achieve full functionality. With built-in and modular measurement, processing, control, and communication capabilities, the CR6 is the only device that is needed.
As a gateway device, the CR6 converts the data measured into the format or protocol required to seamlessly communicate on your network—whether on your computer or the cloud. Entry into the network does not require a separate edge device, as the CR6 also fills this role. Additionally, the CR6 forms a network as a connectivity device via spread-spectrum radio, Wi-Fi, serial, and RS-485.
Using the CR6 as an edge device and gateway with connectivity allows you to standardize on a single platform in your monitoring program. This simplifies purchasing, inventory management, and an overall required knowledge base. The CR6 is capable of a wide range of over thirty-five M2M protocols that include PakBus, MQTT, DNP3, IPv4, IPv6, HTTP/HTTPS, and PPP. Connectivity options include cellular, radio, satellite, Ethernet, and Wi-Fi. These communication methods enable access to critical data and the ability to receive alarms triggered by user-configured thresholds and events.
Native Vibrating Wire Using VSPECT
VSPECT, Campbell Scientific’s patented technology for measuring vibrating wire sensors, significantly improves vibrating wire sensor measurements—regardless of the manufacturer of the sensor. For more details about this unique technology visit our VSPECT® Essentials web resource.
Integrated Benefits for Simplicity and Reduced Costs
The integrated benefits and capabilities of the CR6 make it the most flexible platform available. In addition to several spread-spectrum radio options that are compatible with available frequencies across the world, it also includes Wi-Fi, Ethernet, and compatibility with modular cellular and satellite modems. Using Campbell Scientific communication peripherals ensures complete compatibility and extremely low power consumption.
The built-in charge regulator, with direct connections for main power or solar panels, is used to keep your battery charged. An intelligently designed and maintained power supply ensures long-term functionality and helps to capture data from critical events when you need it.
With regular data collection intervals or remote access, the 4 MB of onboard CR6 memory will likely be sufficient. However, if your application requires high measurement frequency; long, unattended deployments; or data storage redundancy, the CR6 has built-in expandable memory via a microSD card.
Communication Options
The CR6 Automated Monitoring Platform is available in different integrated communications frequency radio options.
CR6-WIFI
The CR6-WIFI comes factory-configured as a Wi-Fi access point. Alternatively, the CR6-WIFI can be configured to join an existing Wi-Fi network with standard or Enterprise (EAP) security.
CR6-RF407
This 900 MHz, 250 mW, frequency-hopping spread-spectrum radio option can join a high-speed “mesh topology” radio network of other CR6s, ideal for medium-range, license-free radio communications.
CR6-RF412
Designed primarily for unlicensed operation in Australia and New Zealand, this 922 GHz, 250 mW, frequency-hopping spread-spectrum radio can join a high-speed “mesh topology” radio network of other CR6s and is also ideal for medium-range, license-free radio communications.
CR6-RF422
Used in the EU and ideal for short- to medium-range, license-free radio communications, this 868 MHz, 25 mW option includes listen-before-talk (LBT) and adaptive-frequency-agility (AFA). It can join a high-speed “mesh topology” radio network of other CR6s using the included RF422 radio.
CR6-RF452
With this internal 900 MHz, 1 W, frequency-hopping spread-spectrum radio option, the CR6-RF452 can be part of a “star topology” network where all radio-frequency (RF) traffic routes back through the gateway. This option is ideal for long-range, license-free radio communications.
Universal Measurement and Control Terminals
The Universal or “U” terminals allow each terminal to be configured to measure a multitude of different types of sensor outputs. This allows the CR6 to be used in many different applications, regardless of the sensor types required—analog, digital, smart, or vibrating wire. This nearly limitless array of sensors includes inclinometers, meteorologic, hydrologic, piezometers, water quality, etc. The flexibility of Universal channels allows you to standardize on a single monitoring platform for all projects.
Support Staff
Recognized for more than 45 years for our outstanding customer support, Campbell Scientific includes experienced product engineering teams, knowledgeable technical support, attentive sales staff, and market-focused professionals who are committed to ensuring your success throughout the lifetime of your project.
Rugged Design
Unique to all CR6 Automated Monitoring Platforms is the design and manufacturing process used to ensure operational integrity in the most extreme environments. Each CR6:
- Includes surge electrostatic discharge (ESD) and over voltage protection, as well as dust protection.
- Is fully tested for shock and vibration tolerance.
- Is factory chamber tested for its full operational temperature range (standard range -40° to +70°C and extended range -55° to +85°C).
- Has been proven in hundreds of real-world applications.
These extreme measures are required to manufacture a product with a meantime between failure (MTBF) of 557 years! This means that if you purchase a CR6 today, your probability of failures during the warranty period (three years) is 0.6%. The CR6 Automated Monitoring Platform will last the entirety of your project, even if that means decades.

The potential transformer and the current transformer provide differential outputs that have galvanic isolation from the voltage and current in the circuit they are measuring. However, there is no need to run the outputs of these transformers into differential inputs of the data logger and unnecessarily consume additional data logger channels. We conducted extensive testing for noise immunity, for inaccuracies from ground loops, and more before concluding that single-ended measurements in the ACPower() instruction have the same performance as differential measurements would provide. Please note that as a result of the galvanic isolation of the potential transformer and current transformer, the data logger ground is NOT connected to the ground of the circuit they are measuring.
Said differently, you can connect differential outputs of a sensor to single-ended inputs of the data logger. However, doing so creates the possibility of poor common-mode noise rejection in the data logger and the possibility of introducing inaccuracies from ground loops between the sensor and the data logger. Note that in this application, the transformer isolation of the potential transformer and the current transformer eliminates these concerns.
Simply connect one of the potential transformer secondary wires and one of the current transformer secondary wires to the data logger ground. Which wire in either case makes a difference, as the phase information allows the measurement of power flowing in either direction. If you measure negative real power when it should be positive, then reverse the secondary wires of the potential transformer where they connect to the data logger. Alternatively, you can reverse the secondary wires on the current transformer, but don't reverse both pairs of wires.

When idle, the CR1000, CR6, and CR1000X consume less than 1 mA @ 12Vdc. Similar to the CR6, the CR1000X has a much faster processor that requires more power when up and running. As such, there will be higher current draws during active measurements, serial communications, or when plugged into a PC via USB or Ethernet.
It may be helpful to think of the CR6 and CR1000X as being built on the same "platform."

Campbell Scientific sells, and embeds in their products, microSD cards that have single-level cell (SLC) memory. In contrast, many electronics retailers sell microSD cards that have multi-level cell (MLC) memory. The difference between these two types of memory is significant.
- The SLC microSD cards from Campbell Scientific are better suited for industrial and environmental applications where wide operating temperatures, low power consumption, and longevity are very important. Most SLC memory cards are designed with industrial applications in mind and, therefore, often have additional perks such as enhanced protection from ESD (electrostatic discharge) and mechanical damage.
- The MLC microSD cards commonly available at electronics retailers are less expensive, but they are generally not well suited for the majority of applications in which Campbell Scientific data acquisition products are used.

- Connect the modem to the RS-232/CPI port on the CR6 using cable pn 31056 (RS-232/CPI RJ45 to DB9 Female DCE).
- Connect the modem to a C or U terminal pair on the CR6, where the pair has been configured for serial I/O.
- Connect the modem to the CS I/O port on the CR6 using an SC105.
