Repair Yes
Calibration No
Free Support Yes

Overview

The RF450 is a frequency-hopping, spread-spectrum radio that operates within the 902 to 928 MHz license-free band. This 1 W radio provides a solution for wireless network communications over longer distances (13 to 60 miles, depending on antenna and line-of sight). Designed specifically for our PakBus® dataloggers, the RF450 works particularly well in point-to-multipoint PakBus networks.

Detailed Description

The RF450 consists of a radio module manufactured by FreeWave Technologies and a Campbell Scientific interface board. It reduces susceptibility to RF interference from other spread spectrum devices by providing user-selectable frequency hopping patterns.

Spread spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This process allows communications to be more immune to noise and interference from RF sources such as pagers and cellular phones.

Compatibility

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.

Dataloggers

Product Compatible Note
CR1000 (retired)
CR200X (retired) The internal radio of the CR200X-series dataloggers should not be used with the RF450.
CR206X (retired) The internal radio of the CR200X-series dataloggers should not be used with the RF450.
CR211X (retired) The internal radio of the CR200X-series dataloggers should not be used with the RF450.
CR216X (retired) The internal radio of the CR200X-series dataloggers should not be used with the RF450.
CR295X (retired) The internal radio of the CR200X-series dataloggers should not be used with the RF450.
CR3000 (retired)
CR5000 (retired) The RF450 does not support a connection with more than one CR5000 or CR9000X datalogger, because the host RF450 radio does not support slave switchable addressing and our CR5000 and CR9000X dataloggers do not have PakBus routing protocol.
CR6
CR800 (retired)
CR850 (retired)
CR9000X (retired) The RF450 does not support a connection with more than one CR5000 or CR9000X datalogger, because the host RF450 radio does not support slave switchable addressing and our CR5000 and CR9000X dataloggers do not have PakBus routing protocol.

Although the CR9000X is compatible, the RF450 does not support its fastest communication rates, and therefore may not be practical for many CR9000X applications.

Mounting Equipment

ENC10/12
ENC10/12R
ENC12/14
ENC14/16
ENC16/18

Additional Compatibility Information

Other Spread-Spectrum Radios

The RF450 can be used in networks containing FGR-115 radios. Campbell Scientific does not recommend using the RF450 with our RF401-series radios or RF430-series radios.

Enclosure Considerations

A desiccated, non-condensing environment is required. The RF450 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.
