Introduction to the KFX Module Operation
The KFX Key Fob Receiver Configuration window is used to configure the
settings of the KFX Receiver module. The KFX receiver is designed to send
bytes of data when Key Fob buttons are pressed or released. These data bytes will
be sent to the target device (such as a NCD relay controller) or any other device
with an XBee socket. This allows the KFX module to be used in many types of
devices provided there is an XBee socket on-board. The KFX comes
preconfigured to operate with NCD relay controllers.
When a Key Fob button is pressed, the “Press” bytes are sent to the target device.
When a Key Fob button is released, the “Release” bytes are sent to the target
device. Note data shown in this control panel are in decimal values. If your
application requires HEX values, then simply convert HEX to Decimal using the
following online tool:

The first number in every row identifies how many bytes will be sent. The
following number boxes indicate the data to be sent. Note that changes MUST be
stored to the KFX module prior to use. Also note, this is a “LIVE” window.
Pressing buttons on the Key Fob should make the associated squares shown in the
control panel turn green.
