The RF411A is a 900 MHz radio designed for license-free use in several countries, including Australia and New Zealand. It provides a hassle-free way to create long-distance wireless links between your computer, data loggers, and measurement devices. The RF411A has a 920 to 928 MHz operating-frequency range and a configurable transmit-power output of 5 to 250 mW.
The RF411A is compatible with all of its RF400-series radio predecessors, including the RF410, RF411, and RF431. This also means that it is compatible with the CR210, CR211(X), and AVW211.
Note: The RF411A radios are recommended for existing installations that require compatibility with products such as the RF411, CR211, and AVW211. For new installations, Campbell Scientific recommends using the RF412 or RF451.
The RF411A is a frequency hopping spread spectrum radio designed for 900 MHz license-free ISM band operation. It has a 920 to 928 MHz operating-frequency range and a configurable transmit power output of 5 to 250 mW. It provides one of three selectable active connections including CS I/O, RS-232, and USB. It has a reverse polarity SMA (RPSMA) antenna jack connection. It is over the air compatible with legacy 9XStream products including the RF410, RF411, RF431, CR210, CR211(X), and AVW211.
