PLEASE READ FIRST
IMPORTANT INFORMATION FOR USERS IN SWEDEN, NORWAY AND GREECE
Please note that these countries do not allow full use of the 863-870 MHz band. The wavebands used can easily be
limited to suit the country requirements by setting a mask in the radio settings. The restrictions in those countries will
not limit the general performance of the radios. Please contact Campbell Scientific for further information.
Antennas sold in Europe for the RF422:
Whip antenna (009964) for use on the desktop and indoor networks (2.1 dBi).
Enclosure mount (009962), wide-band antenna, mounts through the top of an enclosure with 0.4 m cable. Gain ~ 2 dBi.
Wall/pole mount antenna (009965) with 5 m of cable. Gain: ~2 dBi (incl. cable losses). Suitable for use at the base or at
a station where the antenna needs to be raised.
Other higher gain pole mount antenna are available, but the gain must not exceed 2.1 dBi, after allowing for losses in
the cable. Note: raising the antenna is generally beneficial when trying to achieve maximum range.

RF407-type radios, an RF412 can only be used with other RF412-type radios, an RF422 can
only be used with other RF422-type radios, RF427 can only be used with other RF427-type
radios.
Throughout these instructions, RF407-series represents each of the RF407, RF412, RF422, and
RF427 radio options, unless otherwise noted.
See also Specifications (p. 9).
RF407-Series Spread Spectrum Radio 1

1.1 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 signals. The RF407-
series radios reduce susceptibility to RF interference from other spread-spectrum devices by
providing user-selectable frequency-hopping patterns.
The RF407-series radios can provide up to three mile transmission range with an inexpensive
whip antenna. The radios can provide greater than 16 mile transmission range when using a
higher-gain directional antenna at ideal conditions.
1.2 Configuration options
The following images show the most frequently used configurations with the RF-series data
logger and RF-series radio:
RF407-Series Spread Spectrum Radio 2

2. Precautions
lThis 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 Part 15 FCC compliance warning (p. 39) for more information.
lIt is recommended that the RF422 868MHz radio be installed at least 200meters from any
4G LTE cellular transmitter including towers and cellular modems/gateways.
lEnsure 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.
lA Campbell Scientific wall charger is recommended when AC power is used. Any other AC
adapter used must have a DC output not exceeding 16volts measured without a load to
avoid damage to the radio. Over-voltage damage is not covered by factory warranty.
lLine-of-sight obstructions and RF interference will affect the transmission distance. See
Line of Sight Technical Paper and Link Budget Technical Paper for a discussion of
antenna gain and other factors affecting distance.
RF407-Series Spread Spectrum Radio 3

3. Initial inspection
lUpon receipt of the RF407-series radio, inspect the packaging and contents for damage.
File damage claims with the shipping company.
lImmediately check package contents against shipping documentation. 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.
4. QuickStart – Basic networks
NOTE:
This procedure assumes the RF407-series devices are using factory default settings.
4.1 Configure the base RF407-series radio
Configure the RF407-series radio that is connected to the computer. This is sometimes referred
to as the base radio.
RF407-Series Spread Spectrum Radio 4

connect the computer RS-232 port to the RF407 RS-232 port.
4.2 Configure the remote RF407-series data
logger(s)
Follow these instructions multiple times to set up multiple data loggers. In this case, each data
logger must be given a unique PakBus address. For more complicated networks, it is
recommended that you use Network Planner.
RF407-Series Spread Spectrum Radio 6

NOTE:
Most Campbell Scientific devices come from the factory with a default PakBus address of 1.
For this reason, it is best not to assign PakBus address 1 to any device in the network. Then, if
a new device with default settings is added to the system, it will not create a conflict.
1. Ensure the antenna is connected.
2. For data loggers with an external radio, connect the radio and data logger CS I/O ports
using an SC12 cable.
3. Supply 12 VDC power to the data logger.

6. Product description
6.1 Mounting
The mounting holes are designed to align with a one-inch-on-center hole pattern and provide
for either vertical or horizontal mounting. #6-32 x 0.375-inch stainless steel Phillips head screws
and nylon grommets are supplied for securing the radio to the backplate of a Campbell Scientific
enclosure.
6.2 Power
There are three ways the radio may be powered for operation. The radio may be powered via
CSI/O, USB, or the 2.5mm DC power jack.
The Power connector is most commonly used to supply power to the radio when the radio is
used as a standalone PakBus® router / RF repeater or when the RS-232 port is used to
interconnect with another device. Either a Campbell Scientific Field Power Cable or AC to DC
power adapter can be used for supplying 12VDC to the power connector.
The power connector of the radio uses the inner conductor for positive (+) voltage and the
outer/sleeve conductor for ground (–).
CAUTION:
There are many AC adapters available with barrel connectors that will fit the RF407-series
radios. Damage that occurs from the use of an AC adapter that is not the recommended AC
to DC power adapter will not be covered by warranty. If using a different AC adapter, be sure
that the adapter “no load” voltage is below the 16VDC; measure the output with a DC
voltmeter while the AC adapter is plugged into the outlet but not powering anything.
6.3 USB
The radio has a USB Type-B jack that can be connected to your computer by using a USB cable.
The connection is used for power, configuration, and data transfer.
RF407-Series Spread Spectrum Radio 13

NOTE:
INSTALL the DEVICE DRIVER BEFORE connecting the radio to your computer via USB for the
first time. You will need the device driver properly installed before you can connect to the
radio via USB. To install the device driver, download the latest version of Device Configuration
Utility from our website. Under Device Type, select Radio >RF407 Series. Click Install USB
Driver and follow the prompts.
Most host USB ports will supply a sufficient amount of voltage and current for all normal
operations. When used as a base radio, an external power supply is generally not required. When
sourcing operational power from the computer USB port, connect the radio directly to the
computer or to an externally powered USB hub.
When the radio is connected to the computer, a virtual COM port will be added to the list of
available ports. It will be descriptively labeled, for example “RF407 Series (COM10)”, where
COM10 denotes the COM port enumerated by the Windows® operating system.
Regardless of the Active Interface radio setting, the USB port can always be used for connecting
with Device Configuration Utility for radio configuration.
The USB interface is only available for operational, network communications when the radio
Active Interface setting is set as USB.
6.4 CSI/O
The CSI/O port is a 9-pin (male) connector that is typically connected to a Campbell Scientific
data logger by using the supplied SC12 cable. See Table 6-1 (p. 15) for the pinout.
The CSI/O port is not a typical RS-232 connection and is specific to Campbell Scientific products.
CSI/O cannot be used for radio configuration using Device Configuration Utility.
For a typical remote radio site, the radio only needs to be connected to the data logger CSI/O
port by using the supplied SC12 cable. This connection supplies operational power to the radio
and serves as the data connection between the radio the data logger. The Active Interface setting
must be set to CSI/O SDC.
An alternative, but much less common, use of CSI/O is connection to another communications
peripheral through an A100 CSI/O null modem adapter. This is typically only used when creating
a “phone to RF base” configuration. The radio Active Interface setting must be set to CSI/O ME
Master and the other device (for example COM220) must be capable of being configured as a
modem enabled (ME) peripheral.
