Radio communications option
CR300 series-RF data loggers include radio options. The RF407-series frequency-hopping spread-spectrum (FHSS) radio options include the RF407, RF412, RF422, and RF427. RF407-series are designed for license-free use in several countries:
The RF407 option has a 902 to 928 MHz operating-frequency range appropriate for use in the United States and Canada (FCC / IC compliant).
The RF412 option has a 915 to 928 MHz operating-frequency range appropriate for use in Australia and New Zealand (ACMA compliant).
The RF422 option has an 863 to 873 MHz operating-frequency range appropriate for use in most of Europe and some of Asia (ETSI compliant).
The RF427 option has a 902 to 907.5 MHz/915 to 928 MHz operating-frequency range appropriate for use in Brazil.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his or her own expense.
Radio options cannot be mixed within a network. An RF407 can only be used with other RF407-type radios, an RF412 can only be used with other RF412-type radios, an RF422 can only be used with other RF422-type radios,
Throughout these instructions, RF407-series represents each of the RF407, RF412, RF422, and RF427 radio options, unless otherwise noted. Similarly, the RF407-series standalone, or independent radio represents each of the RF407, RF412, RF422, and RF427 models, unless otherwise noted.
The most frequently used configurations with the RF-series data logger and RF-series radio include the following:
