Thisaddendum contains the tuning procedure andservice information for the new board.Note to Installers:For FCC compliance, system components mustbe located where persons are not likely to lingerwithin 20cm (8") of the RF antennas. A 20cm (8")setback is not required provided the antennalocation does not promote lingering within 20cm(8") of the antennas. For example, do not locateantennas adjacent to a chair or bench.
2SETUP AND SERVICE GUIDEDIGITAL MICROWAVE SYSTEM 9158000-0395-02, REV. BAbout the DMS 915The Digital MicroWave System (DMS) 915 is amicrocontroller-based anti-theft system. The DMS915 produces an alarm when it detects aSensormatic tag, a packaged semiconductordiode.To detect the tag, the system performs thefollowing operations:• The system generates a “zone of protection,”typically at a store exit. This zone consists oftwo overlapping fields. The first field is a staticor frequency-hopping, frequency modulatedRF signal. The second field is a frequency shiftkey (FSK) modulated and predominatelyelectrostatic field called an E-field.• When a tag enters the zone, it combines theRF signal and the E-field into a compositesignal that radiates to the system RFantennas. The system detects the compositesignal, separates the modulation, andcompares the recovered modulation to themodulation transmitted. If the two signalsmatch, the system issues an alarm.The DMS 915 is programmed using an externalhand-held computer. Programmable featuresinclude RF hopping bank or frequency selection,RF power level selection, electrostatic fieldfrequency selection, “tag-too-close” functionenable/disable, alarm tone selection, alarmduration selection, selectable hits required foralarm, and alarm count set/reset control.System ComponentsDMS 915 components include E-field radiators, RFantennas, remote alarms, and a programmablepower packThree types of E-field radiators are:• Wire cloth – usually recessed in the floor orsometimes laid on the floor under a rubberpad.• Plate – a metal plate concealed inside apedestal at the side of the exit.• Vortex – a long aluminum bar hung across theexit.The RF antennas are used to radiate thefrequency-hopping, frequency-modulated RFsignal. These antennas mount in a variety of ways.They can be concealed above the ceiling,mounted in pods, concealed in the floor, ormounted in pedestal enclosures located at thestore exit.The remote alarm provides a audio/visual signalthat a tag has entered the “zone of protection.”The power pack powers and controls the system.The pack is typically concealed inside anenclosure.Board ReplacementThe new RF Transmitter/Receiver Board (0300-2469-01) is not compatible with the oldProcessor Board (0300-0928-01). If the old RFTransmitter/Receiver Board (0300-0385-01) isreplaced with a new RF Transmitter/Receiverboard, the old Processor Board also must bereplaced with Processor Board 0300-0928-02.Antenna ConnectionChangeConnect the Impedance Matching Filter (SECp/n 0400-1379-01) to the outer RF port (farthestfrom the IF module). Refer to Figure 1.Connect one of the RF antennas to the filter.Connect the other RF antenna directly to theremaining RF port.
DIGITAL MICROWAVE SYSTEM 9158000-0395-02, Rev. B SETUP AND SERVICE GUIDE 3Tuning ProcedureThe DMS 915 has been pre-tuned at the factory. Ifthe detector is performing satisfactorily, no tuningis required.To tune the detector, do the following:1. Using the laptop configurator or Psionprogrammer, program the Power Pack tothe following settings:E Generator Frequency - 111.5kHzSystem Type - 915RF Power - 10Select RF Bank - 903-905Alarm Settings - n/aNumber of Hits - 1Tag Too Close - OnRF Frequency - 904.2RF Modulation - Off2. Connect the oscilloscope probe to the“Recovered Modulation Monitor” test pointlocated in the IF Module (Figure 1). Set thevertical sensitivity to 1Volt/division and thetime base to 0.5 millisecond/division.3. Move a tag around in the field and changeits orientation until a signal of two voltspeak to peak is observed on the scope. Ifnecessary, the amplitude of the E-FieldGenerator can be adjusted to achieve thisvalue.4. Adjust the variable capacitor on the antennaside of the Impedance Matching Filter untilthe signal on the scope is at a maximum.Adjust the variable capacitor on the powerpack side of the filter to further maximizethe signal amplitude. Repeat thisadjustment sequence of the capacitors untilthe signal reaches its maximum peak value.Note: If the amplitude of the signal exceedsfour volts peak to peak at any time during thisadjustment, turn the E-Field amplitude down totwo volts peak to peak to prevent saturation ofthe amplifiers and consequently false readings.5. Using the configurator, reset the SystemType to “915HOP” after tuning has beencompleted.Figure 1.
