1T-2000 Installation ProcedureCautionChanges or modifications not expressly approved by the party responsible for complianceto the FCC rules could void the user’s authority to operate this equipment.Pre-installation requirements:1. Pedestals must be mounted at least 2-3 feet away from all mechanical and electricaldevices or large metal objects to avoid spurious resonances and noise sources. Thisincludes doorframes, window frames, walls, beams, alarm wiring, etc.1. All system wiring (including the AC power) must enter and exit the center of everyantenna base at a 90-degree angle (down the middle at a right angle to the antennabase). If the wiring makes a turn before it enters or after it exits the base, the turnmust occur at least 1 foot away from the base.2. All system wiring must never run vertically near the antenna. Wiring should rununderneath the floor or on top of the floor in electrical metallic tubing or metallicfloor molding. If the wiring must run vertically, make sure it is at least 3’ away fromthe antenna.3. AC power should be a 3-wire dedicated line.Connect the 18VAC from the transformer to TB4 pin 1 and pin 3 on the RV.Using the red/black 18ga. Twisted pair provided;Connect the red wire from TB4 pin 1 on the RV to TB1 pin 1 on the TX.Connect the black wire from TB 4 pin 3 on the RV to TB1 pin 3 on the TX.All wiring should be run perpendicular to the antennae.Installation:1. Mount the RV antenna and the TX antenna so that the aisle-width is 3 feet.2. Verify that the controls on the TX PCB are set as follows:R45 Center Freq. Pre-set at factory for 8.2MHzR17 Sweep Width Pre-set at factoryR36 Transmit Level Pre-set at factoryJP1 Slave termination HI-ZJP6 MSTR installedJP7 FBR SLV not installedJP8 WRD SLV not installed

Connect a DVM set for VAC RMS to TP1 (VIDEO) and TP5 (GND) on the RV.Adjust P7 until the DVM reads 1 VRMS maximum.6. The TP2 (DISPLAY DAC) test point is multiplexed into eight cells. In order to viewthis test point you must synchronize your scope to the square wave on TP3(DISPLAY SYNC). Set the scope for (+ ) edge trigger and adjust the timebase todisplay only the positive portion of the square wave on TP3. Connect a second scopeprobe to TP2, adjust the GND reference at the bottom of the display, adjust thevertical sensitivity for .5V/div. and set the scope for CHOP. Adjust the TP2 scopeinput for DC couple and observe that the trace has approximately 2.5VDC offset(DAC offset). You should see four discrete traces from left to right (easier to view ifyou shut off the trace for the display sync.). The cells are as follows:Signal ChannelNoise ChannelLow band energy levelHigh band energy levelAlthough the Alarm threshold has been pre-set, it can be adjusted. Adjust P2 on theRV until the signal channel is approximately 0.7VDC lower than the noise channel.When the signal channel exceeds the noise channel and the high band energy levelexceeds the low band energy level the alarm is triggered.7. Set the TP3 scope input for (-) edge trigger to view the remaining four cells which areas follows:Short term averagerDifferential averagerBeacon displayLong term averager8. Observe the short term averager on TP3 as outlined in the previous step. Thesynchronous energy on the short term averager should be less that 0.5Vp-p.9. Remove all test equipment and close the antenna base covers. Verify that the system
4is working properly with appropriate tag.10. Demonstrate the system to the storeowner or manager and obtain signature oninstallation acceptance form.
