General Description
The SD 2.0 Wireless Radio is a 2.4 GHz 2-way radio module intended for wireless
transmission of sensor data. The board’s small package and modular design facilitate
integration with a wide range of sensors, and in particular it is designed to be
permanently mounted to KCF’s line of Smart Diagnostics sensors.
The radio features a proprietary multi-frequency network protocol to allow simple setup
and operation of up to 100 sensor nodes per receiver, making it an ideal solution for
multi-point monitoring of industrial equipment. The communication protocol of the radio
is highly configurable to allow tailoring of data collection to numerous different
applications. Sampling rate, collection interval, input channels, etc. are all adjustable by
the user.
The radio is designed to be attached via land-grid-array (LGA) soldering to the sensor
board it is serving, thereby minimizing the size of the entire sensor/radio package and
eliminating the size, expense, and long term reliability risks of a connector. The radio is
powered via the LGA connection to the sensor board.
The radio communicates using an antenna provided by KCF which attaches to the radio
module using a standard U.FL connector.

FCC Compliance Information
FCC ID: Z5ISD2
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
Changes or modifications to this device (including operating at different power
levels or substituting a different antenna) not expressly approved by KCF
Technologies, Inc. may void the user’s authority to operate this equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
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. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
CAUTION: to minimize RF exposure it is recommended to maintain a minimum
separation of 20cm between the device and the user during operation.
