General Description

The RF430 spread spectrum radio includes a USB port to make it easier to connect to newer computers that do not have RS-232 ports. This 100 mW spread spectrum radio/modem operates in the 910 to 918 MHz frequency range, which is allocated in the US and Canada. The RF430 can transmit data to another RF430 radio, an RF401 radio, or a CR206(X) datalogger.

Usually, the RF430 radio connects to a PC’s USB port to serve as a base station modem/radio. The RF430 may also connect to the datalogger’s RS-232 port to serve as a field modem (requires a null modem cable and a field power cable).

Spread spectrum radios distribute the normally narrowband information signal over a relatively wide band of frequencies. This improves performance in environments of RF noise, multipath, pagers, and cellular phones. The RF430 reduces susceptibility to RF interference from similar spread spectrum devices by providing user-selectable frequency hopping patterns. Operation of the RF430 does not require that the user be assigned an FCC license.

RF430 and RF401 Differences
The RF430 radio is functionally the same as the RF401. The difference between the two is that the RF430 has both USB and RS-232 ports, while the RF401 has RS-232 and CS I/O ports.
