NOTE:
RF451/RF452 has the same operating-frequency range as RF407; however, it has a higher
output power. This allows for greater communications distance but also requires more
power. To preserve battery power, it may be necessary to only turn on the radio during
certain periods of time. See
Validating CRVW3 radio operation
NOTE:
The CRVW3 –RF407, –RF412, –RF422, and –RF427 options are all versions of the same radio
series. This manual will refer to a CRVW3 with any of these options as “CRVW3–RF407.” The
standalone radios will be referred to collectively as “RF407.” Throughout this manual, RF407
can be replaced with RF412, RF422, or RF427, unless otherwise noted.
NOTE:
This manual refers to using RF451/RF452 standalone radio(s) in a CRVW3–RF451/RF452
network. The RF450, can also be used with CRVW3–RF451/RF452s. The configuration settings
are the same for RF450s and RF451/RF452s. See the RF450 manual for more information on
configuring the RF450. Note that RF450 uses a different antenna connector than
RF451/RF452 (SMA instead of RPSMA), so antennas are not interchangeable between the two
devices.
CRVW3 operation is controlled by software-configured settings made on the device. No CRBasic
programming is required. Frequency and temperature measurements are obtained at the
specified measurement interval. Optional engineering output can be calculated using advanced
settings.
