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.Read More
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.

The RF411A is over the air compatible with the RF411, RF431, CR211, CR211X, and AVW211.
The RF411A is also compatible with the RF410 and CR210, but the communication protocol must be set to transparent. Also, if RF410 and RF411A radios will be in the same RF proximity, do not use 28, 44, 52, 56, or 60 for the RF410 Net Address. RF410 radios with Net Addresses of 28, 44, 52, and 56 interfere with RF411A radios with Net Addresses of 0, 1, 2, and 3, respectively. The RF410 Net Address of 60 interferes with all RF411A Net Addresses.
Campbell Scientific does not recommend using the RF411A in networks containing FGR-115 or RF450 radios.
Do not mix RF411A radios using the Transparent protocol setting with RF411A, RF411, RF431, CR211(X), or AVW211 devices using a PakBus protocol setting. This will produce unsuccessful RF traffic. However radios with the PakBus Aware and PakBus Node settings can coexist in the same network.

*Use a 18663 null modem cable.
**It is possible to connect a mixed-array data logger (e.g., CR10, CR10X, CR23X, 21X, CR7) by using an SC932A or SC105 between the data logger's CS I/O port and the RF411A's RS-232 port.

The RF401A and RF411A have distinct advantages over their predecessors, including greater maximum transmit power, lower average power consumption, improved packaging, and the inclusion of USB, RS-232, and CS I/O on a single device.
These radios ship with an SC12 serial cable and a 10873 RS-232 cable.
The USB device driver for this product has been packaged with the Device Configuration Utility. Please ensure that you are using the latest version of the Device Configuration Utility.
Antenna selection depends on multiple criteria:
To help with antenna selection and site placement, consider renting and using a demo kit to test the pathway quality. Campbell Scientific offers a 900 MHz demo kit for the RF401, RF430, CR206X, and AVW206, as well as a demo kit for the RF450. Contact Campbell Scientific for assistance.
