Instruction Manual

RF401-series and RF430-series Spread Spectrum Radio/Modems

• RF430 915 MHz Spread Spectrum Radio—transmits data to another

RF430 radio, RF401 radio, or a CR206(X) datalogger. The 915 MHz

frequency is used in the US/Canada.

• RF431 922 MHz Spread Spectrum Radio—transmits data to another

RF431 radio, an RF411 radio, or a CR211(X). The 922 MHz frequency is

used in Australia/Israel.

• RF432 2.4 GHz Spread Spectrum Radio—transmits data to another RF432

radio, an RF416 radio, or a CR216(X). The RF432 is intended mainly for

certain European and Asian markets.

If the RF430’s operating system is prior to OS2, its USB port will

only communicate at 38.4 kbps. Therefore, the RF430 operating

system will need to be updated to a newer version if the network

will contain dataloggers that do not support 38.4 kbps. Operating

system updates are available from

www.campbellsci.com/downloads.

FIGURE 1-2. RF430 has a USB port allowing it to be connected

directly to a PC’s USB port.

Unless specified otherwise, throughout this manual RF430 refers

to the RF430, RF431, and RF432 radios.

1.3 Combination Mode Communications

Besides the “direct” to PC communications described in the Quick Start and

Installation sections, it is possible to combine methods in datalogger

communications. Some examples:

• Phone to RF401: PC to external modem to COM220 to RF401 to

datalogger (see Appendix I, Phone to RF401 Series)
