The location and orientation of the module are important factors in the RF performance. With the unit located outside of
any metal enclosures, the antenna is adjusted to achieve the best range. The range is dependent on its placement and the
building in which it is used. The construction of the building, obstructions, and RF interference from other devices are
factors determining the effective range of the unit. To prevent unit-to-unit RF interference, multiple modules operating at
the same frequencies should not be installed within 3-5 feet of each other.
Physical Description
The module, shown below, consists of various components attached to a printed circuit board. A set of
spring loaded pogo-pins connect to the antenna that is mounted in the plastic button frame. A 10-pin
header is provided for the application-specific installation.
There are six (6) different build options for this module. The options specify the number of installed
push buttons/switches, the number and color of installed LEDs.
