Page 12: Introduction
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 volts measured without a load to avoid damage to the radio. -
Page 13: Quickstart
• Thoroughly check all packaging material for product that may be trapped. Contact Campbell Scientific immediately about any discrepancies. Model numbers are found on each product. On cables, the model number is often found at the connection end of the cable. -
Page 14: Overview
RF407-Series Spread Spectrum Radio Overview Spread-spectrum radios spread the normally narrowband information signal over a relatively wide band of frequencies. This allows the communications to be more immune to noise and interference from RF sources such as pagers, cellular phones, and multipath. The RF407-series radios reduce susceptibility to RF interference from other spread-spectrum devices by providing user- selectable frequency-hopping patterns. - Page 15 RF407-Series Spread Spectrum Radio LBT + AFA Compliance and Performance Complies with ETSI duty cycle requirements. Radio communication effective duty cycle = (number of channels • 100) / 3600. Channel Spacing: 100 kHz Receiver Bandwidth: 150 kHz Modulation Bandwidth: < 300 kHz LBT Threshold: <...

RF407-Series Spread Spectrum Radio You will be prompted to save your configuration. Doing so will allow you to easily recall the configuration later or apply this same configuration to other devices. LoggerNet Setup Basic Setup Start LoggerNet and open the Setup screen from the Main category of the toolbar. - Page 23 RF407-Series Spread Spectrum Radio With the setup tree entered, you will now need to complete the configuration of each element. Start with selecting the ComPort element at the root of the tree. Under ComPort Connection, select port labeled RF407-Series.
- Page 24 RF407-Series Spread Spectrum Radio Select the PakBusPort element in the tree, and select the PakBus Port Always Open checkbox. Set the Maximum Baud Rate to 115200.
- Page 25 RF407-Series Spread Spectrum Radio Finally, select your datalogger in the tree. Set the PakBus Address field to the address of your datalogger. Enter the Security Code, if security has PakBus ® been set up in your datalogger. Press the Apply button to save your changes. You are now ready to connect to your datalogger using the LoggerNet Connect screen.

PakBus ® address of the RF407 series in the PakBus Address field. If the repeater is the first hop from LoggerNet, it should always be shown in the network map. This will force routes to go through the repeater. If the repeater is further down the network, it may still be helpful to display it in the network map. -
Page 27: Antenna Selection, Placement, And Mounting
RF407-Series Spread Spectrum Radio and urban areas tend to evolve over time meaning new sources of interference may develop over time. 10.2 Antenna Selection, Placement, and Mounting Antenna selection and placement can play a large role in system performance. Often directional antennas are preferred over omnidirectional antennas when possible as RF energy can be more selectively directed and received and higher gains can be realized without the consumption of additional power. -

RF407-Series Spread Spectrum Radio transmission. When an RF packet fails to be acknowledged by the destination, the radio will delay a random amount of time before resending the packet again. A receiving radio responds to the sending radio with an ACK packet for every radio packet it receives addressed to it with a valid CRC. -

Central Router. A valid setting is a single address between 1 and 4094. When set, the RF407 series will act as a branch router. Specifying a central router address can reduce the amount of PakBus RF traffic by eliminating the exchange of neighbor lists with routers beyond the central router. -

Page 40: Distance Vs. Antenna Gain, Terrain, And Other Factors
Gain, Terrain, and Other Factors B.1 Introduction The communication distance you can expect to obtain using the RF407 series depends on a number of factors that are unique to every installation. These unique factors are the path of propagation, relative antenna elevations, and the link budget. -
Page 41: How Far Can You Go
In some cases, an in-line RF amplifier may be used to provide additional system gain, but this is rare and not typical of Campbell Scientific installations. Losses derive from the attenuation of the RF signal as it propagates through the transmission lines (coaxial cables, surge suppressor, etc.) connecting the... -

Page 44: Receiver Sensitivity
Appendix B. Distance vs. Antenna Gain, Terrain, and Other Factors B.2.6 Receiver Sensitivity Receiver sensitivity is usually specified in dBm for a specific bit error rate (BER). The transceiver module used in the RF407 series is specified at –101 dBm at ~10 –4 raw BER. - Page 45 Appendix B. Distance vs. Antenna Gain, Terrain, and Other Factors and interferes with the main signal. This phenomenon gives rise to the 2-Ray Multipath Propagation Model for estimating real world distances. The path geometry defined by the relative elevations of the antennas and the distance between the antennas is a significant factor in determining the degree of interference from the reflected wave.
