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
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)
