3.2 DEACTIVATOR OPERATING MODES
The deactivator unit can o n l y work in 1 mode.
MODE1 - deactivation with detection - The deactivator emits ‘deactivation output power’
pulses, which are defined by TX PWR trimmer. The response after deactivation pulse is
analyzed in order to look for the presence of sticker label or tag inside detection area
(above or under deactivation pad).
4. CONFIGURATION OF DEACTIVATOR'S PARAMETERS
4.1 THE USAGE OF ONE OR TWO DEACTIVATOR PADS
If it is intended the usage of the only one deactivation antenna (deactivation pad) it makes
no difference, if it is connected to the terminal ANT1 or ANT2. We recommend keeping
recommended dimensions of the deactivation antenna; it fits 90 % of installations.
The usage of two deactivation antennas/pads can be requested in some cases. It can
happen mainly in three following cases:
1. It is requested to have two deactivation antennas/pads, which are not distant
more than approximately 2-3 m (for example one can be normal deactivation
pad and the second one can be embedded into bar code reader).
2. One deactivation antenna/pad is required, but bigger deactivation field is
requested than one deactivation pad can give.
Both of deactivation antennas should be connected to terminals ANT1 and ANT2 (for
example first deactivation antenna can be connected to the terminal ANT1 and second
one to the terminal ANT2). Both of antennas will work the same way as per settings of the
operational mode (MODE1, MODE2, MODE3 or MODE4).
