RF401A-Series Spread Spectrum Radio
1. Introduction
This manual discusses the configuration, operation, and maintenance of the
Campbell Scientific RF401A and RF411A frequency-hopping spread spectrum
(FHSS) radios. This manual will refer to these devices collectively as either
“radio,” “RF401A series,” or “RF401A-series radio” unless otherwise noted.
The RF401A-series radios are designed for license-free use in several
countries. The RF401A has a 910 to 918 MHz operating-frequency range
appropriate for use in the United States and Canada. The RF411A has a 920 to
928 MHz operating-frequency range appropriate for use in Australia and New
Zealand.
The RF401A-series radios provide a high level of RF compatibility with
previous products. The RF401A is compatible with the RF400, RF401,
RF430, CR205, CR206, CR206X, and AVW206. The RF411A is compatible
with the RF410, RF411, RF431, CR210, CR211, CR211X, and AVW211.
2. Cautionary Statements
• This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. See Appendix A,
Part 15 FCC Compliance Warning, for more information.
• Ensure maximum protection against surges. Use coaxial (antenna) surge
protection. Keep RS-232, CS I/O, and USB connections short or use
protective isolation and surge protection when appropriate.
• Where an AC adapter is used, Campbell Scientific recommends pn 15966.
Any other AC adapter used must have a DC output not exceeding 16.5
volts measured without a load to avoid damage to the radio. Over-voltage
damage is not covered by factory warranty.
• Campbell Scientific does not recommend using RF401A-series, RF401-
series, or RF430-series radios in networks containing RF450 radios. The
RF450 radios will interfere with the transmission of the RF401A-series,
RF401-series, and RF430-series radios.
• Line-of-sight obstructions and RF interference will affect the transmission
distance. See Appendix B, Distance vs. Antenna Gain, Terrain, and Other
Factors, for a discussion of antenna gain and other factors affecting
distance.
3. Initial Inspection
• The RF401A-series radios ship with an SC12 serial cable, a USB A to
USB B Cable, 2 grommets, and 2 screws.
• Upon receipt of the RF401A-series radio, inspect the packaging and
contents for damage. File damage claims with the shipping company.
Contact Campbell Scientific to facilitate repair or replacement.
