RF401A-Series Spread Spectrum Radio
7. Product Description
7.1 Mounting
The mounting holes are designed to align with a one-inch-on-center hole
pattern and provide for ridged mounting of the radio in either a vertical or
horizontal orientation. #6-32 x 0.375 inch stainless steel Phillips head screws
(pn 505) and nylon grommets (pn 6044) are supplied for securing the radio to
the backplate of a Campbell Scientific enclosure.
7.2 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 labeled as Power.
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 for interconnect with another device. The Field Power
Cable (pn 14291) or AC to DC power adapter (pn 15966) are 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 (–).
There are many AC adapters available with barrel
connectors that will fit the RF401A series. Damage that
occurs from the use of an AC adapter that is not the 15966
AC to DC power adapter will not be covered by warranty. If
using a different AC adapter, be sure that the adapter’s “no
load” voltage is below the 16.5 Vdc; measure the output with
a DC voltmeter while the AC adapter is plugged into the
outlet but not powering anything.
7.3 USB
The radio has a USB Type B jack that can be connected to your PC using the
supplied 17648 USB cable. The connection is used for power, configuration,
and data.
INSTALL the DEVICE DRIVER BEFORE connecting the radio
to your PC 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 | RF401A Series. Click the Install the USB
device driver link 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 PC’s USB
port, connect the radio directly to the PC or to an externally powered USB hub.
