1. BASIC INFORMATION USE: The deactivator is determinate for the deactivation the RF sticker labels in frequency range 8.2 MHz ± 3.625 %. The deactivator can also detect deactivation less hard tags in the above-mentioned frequency range. The deactivator works with all kinds of hard tags and sticker labels in the market for 8.2 MHz The synchronization between deactivators and EAS system is the way for the elimination of bad influence between the deactivators and EAS system.
3. DEACTIVATOR PARAMETERS AND THEIR MUTUAL INTERACTIONS 3.1 SENSING AND DEACTIVATING POWER The deactivator needs two output power levels for its operation. RX Sensitivity Level - Is used for the detection of sticker labels and tags. The bigger this power is the higher detection height is reached, but the higher the probability is, that the sticker label is deactivated before its detection.
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.
4.2 SETTINGS OF THE DEACTIVATION POWER The deactivator deactivation power is determined by settings of the TX PWR trimmer. The value of this parameter determines the height of the deactivation field. This level should be chosen the way to assure the reliable sticker labels deactivation. There is general rule valid, that 50 % level of output power is sufficient for the most sticker labels. Th e va l u e of this parameter is set at 50 %; setting beyond this level is not allowed by the manufacturer.
5. INSTALLATION There are several simple and essential rules mentioned, which keeping will assure very good parameters of the deactivation. • Don’t install deactivation antennas/pads to the near proximity of metal objects. There should be no metal object under the deactivation antenna/pad closer than from 3 to 4 cm. There should be no metal object next to the deactivation antenna/pad closer than from 5 to 10 cm.
6. ELECTRONIC BOARD DESCRIPTION 6.1 TERMINAL DESCRIPTION Pic. 3 - Location of terminals on the board. SWITCH - The deactivator switch. AC 15V - Power supply terminal (AC 15V/11VA). EXT.DEAC - Reserved for the future board expansion. LF SYNC OUT – Not used in USA ANT1 ANT2 - Deactivation antennas terminal.
6.2 JUMPERS AND DIP SWITCH DESCRIPTION Pic. 4 - Location of jimpers and DIPs on the board. JP1 - The free place for spare jumpers. JP2 - Source of high frequency synchronization. JP3 - Delay between received trigger signal and the transmitted one – in mode of low frequency mode.(Not USED IN USA MODEL) JP4, JP5 - In order to be able to put antenna on resonance, the effects of loop geometries and different cable lengths can be composed to certain degree.
6.3 TRIMMERS DESCRIPTION Pic. 5 - Location of trimmers on the board. TX PWR - Deactivation output power (set at 50%). RX PWR - Sensing output power (set at 50%). Stepping - The range of sweeping is set from the production fixed at 50%.
Pic. 6 - Location of LEDs on the board. 7. DECLARATION 7.1 EQUIPMENT MODIFICATION CAUTION Equipment changes or modifications not expressly approved by manufacturer, the party responsible for FCC &/or CE compliance, could void the user's authority to operate the equipment and could create a hazardous condition. 7.2 FCC COMPLIANCE “This equipment has been tested and found to comply with the limits for Class A digital device pursuant to Part 15 of the FCC Rules.
