TUNING PROCEDURE TR4022____________________________________________________________________________________________________________________________CHECKPOINT SYSTEMS, INC. CONFIDENTIAL AND PROPRIETARY INFORMATION, FOR INTERNAL USE ONLY.Rev. 00 Page 31.0 INTRODUCTIONThis document describes the procedures required to properly tune a Strata System with theTR4022 board. Many of the adjustments for the Strata are pre-tuned during the manufacturingtest process therefore adjustments required in the field have been minimized.Adjustments such as center frequency and sweep are preset for 8.2 Mhz operation. If the systemis required to detect a different frequency tag the sweep range will need to be readjusted by theinstaller.Once properly configured, if poor performance results, the CSE should direct their efforts towardfinding the source of the interference in the environment. Several test signals are provided by theTR4022 board, which may be viewed on an oscilloscope. These signals allow the CSE to identifyand measure ambient noise levels, resonances and other sources of environmental interference.The DSP (digital signal processor) system automatically subtracts stationary resonances seen bythe antennas. The system offers flexibility to adjust for these circumstances. However, thesolution for environmental problems, is to determine the environmental problems and resolvethem. The options for adjusting to environmental problems are performed both in the analog anddigital realm by the technician. The analog solutions are reducing power on the transmit antennas(2-loop and/or 3-loop), reduce the baseband gain, and adjust the sweep. In the digital toolboxthere are four user selectable filter parameters. These tools should be used only after the CSE hasattempted to correct the environment.The Strata system is powered by a +24Vdc power supply, P/N 121878. This power supply canpower up to a maximum of three antennas.2.0 SYSTEM DESCRIPTIONThe Strata system is a transceiver design using both a 3-loop, 2-loop, and a 1-loop antenna design.The Strata alternates between using the 2-loop antenna and the 3-loop antenna. The 1-loopantenna is used as a shield that is tied to ground. This technique provides the system withdifferent views of the detection field allowing the system to improve detection by minimizing theholes typically found at the crossbars of typical swept antennas.During an antenna’s cycle, the system performs two “blasts” which are called a “bin”. There aresixteen bins per frame. A bin consists of two “noise” cycles and two blast cycles, a blast is atransmit cycle and then a receive cycle. During the noise cycle, the system is not transmitting,only receiving ambient noise. This allows the system to establish the baseline noise level of theenvironment for later comparison. The system then transmits or “pulses” the field and thenreceives or “listens” for an echo of a tag signal. This frame is repeated on the other antenna. Atag response need only be present on one of the antennas to cause an alarm. In effect the systemprovides the best of both worlds, a 2-loop and 3-loop design.

The illustrations on thenext pages shows the position of the jumpers, switches, and potentiometers on the TR4022 boardused during configuration. The top of the shield is held with 4 thumb turn screws. With the top ofthe shield removed all the switches can be set without removing the electronics from the antenna.If for some reason the circuit board needs to be removed from the antenna housing, remove thethree mounting screws from the backside of the board housing. Removing the rear cover of theantenna assembly can access them. Before completely removing the electronics package from theantenna loosen the screw near the TX1 and TX2 antenna connector and remove the spade lug.MAKE SURE WHEN REINSTALLING THE ELECTRONICS PACKAGE THAT THE SPADELUG FROM THE SHORTED TURN IS REINSTALLED IN THE SAME PLACE.

(At the end of an alarm cycle the inhibit LEDwill light momentarily)DS2 – Alarm This LED indicates the system is alarming (useful for when the sounder and lights aredisconnected).DS3 - HeartbeatThis LED indicates the system is operating normally. This LED blinks at an approximate1 Hz rate. If the led is not blinking, it is a catastrophic failure and the board should bereplaced.DS4 – Transmitter StatusThis LED indicates the ‘power’ level of the transmitter, this led is normally on.

CONFIDENTIAL AND PROPRIETARY INFORMATION, FOR INTERNAL USE ONLY.Rev. 00 Page 19Screen 78.0 TUNING8.1 Master / Slave SetupThe first step in the process for tuning a Strata pedestal with the TR4022 board is toconfigure SW 6-1 according to how the pedestal is used in conjunction with otherpedestals. Configure either as a Master (ON) , or Slave (OFF). See Switch 6 –Master/Slave configuration8.2 Group Addressing (VERY IMPORTANT)If the pedestal is working as part of a group of pedestals and connected together by theinterpedestal cable, set the group address at SW5-1, 2, 3 the same for all the pedestals inthe group. See Table 4. If a pedestal or group of pedestals is installed within 40’ of oneanother then they may have to be slaved. When slaving is required the group address forall the pedestals must be set the same.8.3 SlavingSlaving can be accomplished by attaching a two wire shielded cable with a drain wire tothe OUT connector J8 terminals 4 & 5 (drain wire to terminal 3) on the last pedestal in thegroup to the IN connector J7 terminals 4 & 5 (drain wire to terminal 3) on the firstpedestal of the next group. NOTE: Polarity of the wires is important.Screen 7Alarm Counter Display (above shows 29)
TUNING PROCEDURE TR4022____________________________________________________________________________________________________________________________CHECKPOINT SYSTEMS, INC. CONFIDENTIAL AND PROPRIETARY INFORMATION, FOR INTERNAL USE ONLY.Rev. 00 Page 20Apply 24 VDC power and check that DS11 is illuminated. DS3 should also be flashingintermittently.The transmitter output is preset at the factory and should not require adjustment.Adjust the baseband gain potentiometer R89 for a noise level of less than 1.5V at Screen1. This can be viewed by attaching an oscilloscope to the DAC test point TP16 andselecting Screen 1 by depressing SW2. Scope setting: 1V/DIV; 200uS/DIV.While viewing Screen 1 check the sweep setting of the transmitter for the frequency of thetags being used. Standard retail systems are set to sweep from 7.6 – 8.7 Mhz. Using aGrid Dip Meter placed flat on the floor approximately 1.5 to 2 feet from the antennacheck the sweep range by varying the frequency dial on the meter. The followingillustrations will give you an idea of what the induced signal from the Dip Meter will looklike at Screen 1. 8.7 Mhz 8.2 Mhz 7.6 MhzSet the detection parameters at SW4-3 & 4 to OFF/OFF. This is the same as the ‘C’ filteron earlier Strata. If more filtering is required because of environmental influences seeTable 3.Set SW5-4, 5, 6 for the type of tags being used. See Table 4. All OFF has no ‘Q’qualification and thereby will not defeat alarms caused by merchandise.Set the volume of the Sonalert by adjusting potentiometer R46.No other adjustments are required. Test the system with several of the customers’ tags toinsure that the system is detecting properly. The sensitivity of the system may vary due toenvironmental influences and the selection of the filtering set by SW4-3 & 4.
