Detailed Description

The FGR-115RC supported point-to-point and point-to-multipoint networks. It could serve as a field radio/modem connected to a datalogger, as a stand-alone repeater not connected to a datalogger, or as a base station radio/modem connected to a computer.

Freewave's FGR-115RC 1-Watt Spread Spectrum Radio was retired in July 2007.

Compatibility

Communications

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

Datalogger Considerations

Compatible Contemporary Dataloggers

CR200(X) Series CR800/CR850 CR1000 CR3000 CR9000X
* **

Compatible Retired Dataloggers

CR500 CR510 CR10 CR10X 21X CR23X CR9000 CR5000 CR7X
**

Notes:
*The internal radio of the CR200(X)-series loggers should not be used with the FGR-115RC.

**Although the CR9000X and CR9000 are compatible, the FGR-115RC radio does not support their fastest communication rates, and is therefore not practical for most of their applications.
