* 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. An
antenna is attached to the circuit board while a 25-pin header is for the application-specific installation.
