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 used in the US and Canada. The RF430 can transmit data to another RF430 radio, an RF401 radio, or a CR206(X) datalogger. The RF430 supports point-to-point and point-to-multipoint communications. Although it typically serves as a base station modem/radio, the RF430 can connect to the data logger’s RS-232 port to serve as a field modem (requires a null modem cable and a field power cable).
