The RF430, RF431, and RF432 radio modems are functionally the same as the RF401, RF411, and RF416 models, except for a change to their ports. The RF430-series radios have a USB port instead of the CS I/O port that the RF401-series radios have. The USB port makes it easier to connect to newer computers, and the RS-232 port still allows them to be connected to our current dataloggers. Networks can include a mix of the RF430-series and RF401-series radios.
The RF431 spread-spectrum radio has a 920- to 928-MHz operating frequency range, which is used in Australia and Israel. Spread-spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This improves communication performance in locations where RF noise, pagers, cellular phones and multipath could cause interfence. The RF431 reduces susceptibility to RF interference from similar spread-spectrum devices by providing user-selectable frequency hopping patterns.
The RF431 supports point-to-point and point-to-multipoint datalogger communications. It can serve as a field modem/radio while connected to the datalogger or as a base station modem/radio when connected to a computer. The RF431 modem can also be used for general-purpose wireless data communications.
