1Transceiver Exciter Installation GuideIntroductionThe exciter is an additional Low Frequency (LF) antenna for a Transceiver. By using exciters, additional LF Fields can be created and the tag detection zones can be extended.Each Transceiver supports a maximum of three transceiver exciters. The LF Fields of the Transceiver and all exciters will be in phase.Figure 1: Exciter Front PanelThe exciter is connected to a transceiver (Part Number SR4TX01) from the exciter’s XCVR PORT to any one of the transceiver’s three SATELLITE EXCITERS ports using a standard ethernet cable (CAT5, EIA 568A termina-tion). The exciter also draws its power from this connection.Firmware UpdatesThe exciter does not contain firmware. Its operating features are dependent on the Transceiver.Installation TipsWhen installing the exciter:• Use both mounting holes to ensure that the exciter is secure.• Mount the exciter so that the front panel is easily accessible and visible from thefloor. If mounting above a ceiling, place the exciter so that the front panel is visiblefrom the floor when a ceiling tile is removed.• Check that the LF Field radiated by the exciter(s) and the Transceiver is continuous(no dead spots) and that it covers the correct area. See “Configuration” on page 4.Location SelectionAny of the following are suitable locations for an exciter:
2Transceiver Exciter Installation Guide• On the wall above the egress point or monitored area.•Inside a wall cavity.• On the sidewall along the hallway mounted flat against the wall.Location ConsiderationsWhen planning the exciter location, consider the following: •Ceiling Height and Corridor Width — The exciter LF Field should extend to thefloor and from one wall of the corridor to the other. Tags must not be able to passunder or around the LF Field.•Any Nearby Metal — Large metal surfaces close to the exciter can distort theLF Field in unpredictable ways. This effect can increase or decrease the LF Fieldstrength and even extend the LF Field shape. At times this effect can be used toadvantage but the desired result can only be obtained experimentally. Metal plate,foil, or mesh must not come between the exciter and the tags to be queried and read.The exciter top, bottom, and rear panels must be at least 3 in. (7.6 cm) from anymetallic surfaces. •LF Field Shape — In the absence of large metal objects the LF Field is a sphere witha 15 ft. (4.5 m) maximum radius centered around the exciter. As a result, theLF Field range is unaffected by rotating the exciter, or by placing the exciter verti-cally or horizontally.•Adjacent Floors — If the LF Field extends into adjacent floors, it will cause tags onthe adjacent floors to be reported as if on the exciter floor.LF Field CoverageWhen the exciter is used to monitor an egress point, such as a door or elevator, the LF Field(s) should cover all possible approaches. As many as three exciters can be used with a single Transceiver to modify the LF Field for this application.Tags must be detected at least 8 ft. (2.4 m) before the door when the Transceiver is part of a door locking system. This ensures adequate time for the lock to ener-gize before the tag reaches the doorway.The LF Field should not extend into adjacent areas, including adjacent floors, containing tags. These tags could cause the Transceiver to activate the lock even though tags are not approaching the exit.Exciter InstallationTo install the exciter:1 Mount the exciter with #8 hardware using the two mounting holes.2 Record the exciter location for later consideration.3 Route the cable (not supplied) from the exciter to the Transceiver.
3Transceiver Exciter Installation Guide4 Disconnect the Transceiver from its power supply.5 Plug the cable into the Transceiver and the exciter.6 Reconnect the Transceiver power supply.7 Verify that the exciter power LED and the field intensity LED are on. See Figure 1 for the location of these indicators. If they are not lit, check that the Transceiver has power, and that the cable plug is properly inserted.8 Adjust the exciter LF Field as described in “Configuration” below.ConfigurationThe exciter is configured by adjusting the LF Field strength and size. Before you set the LF Field StrengthEnsure that the Transceiver UHF Threshold is properly set: That is, the red UHF Rx LED on the Transceiver is lit most of the time but continues to flicker occasionally. If this is not true, set the UHF Threshold as described in the Trans-ceiver Installation Manual.The LF Field causes a tag to transmit a UHF message to the Transceiver. When in test mode, the Transceiver beeps when a tag message is successfully received. The beeping sound allows you to estimate the LF Field size. The LF Field should be:• Strong enough to make the tag respond throughout the desired area. That is, theTransceiver beeps continually while the tag is anywhere within the desired area.•Not strong enough to make the tag respond outside of the desired area. That is, theTransceiver does not beep when the tag is outside of the desired area.•Not strong enough to bleed onto adjacent floors. That is, the Transceiver does notbeep when the tag is on an adjacent floor.To set the LF Field:1 Set test mode by moving switch 1 down on the transceiver’s MODE DIP swtich block. 2 Confirm tag operation by holding the tag close to the Transceiver. The Trans-ceiver should beep continuously. 3 Using the tag, explore the desired coverage area while constantly re-orienting the tag with respect to the exciter. The Transceiver should beep continuously.Within the desired coverage area there may be locations with low LF Fieldstrength called dead spots. The Transceiver will stop beeping when the tagenters a dead spot. The size and number of dead spots should be minimized.However, a small number of dead spots may be acceptable.
4Transceiver Exciter Installation GuideSome dead spots are less important than others. For example, if the aim is torecord the movement of tags through a door, a dead spot far from the doormay be less important than one near the door.4 If the dead spot size and number is unacceptable, or if the LF field coverage area is too small, increase the strength of the LF field by turning the LF FIELD ADJ screw on the exciter clockwise. The exciter adjustments are delicate. Do not turn the adjustments forcefullyto the limits. Do not needlessly wiggle or turn the adjustments. As you turn the LF FIELD ADJ screw, the LF FIELD INTENSITY Indicator becomes: w Brighter as you turn the ADJ screw clockwise and increase the LF Field strength; —or— w Dimmer as you turn the ADJ screw counterclockwise and decrease the LF Field strength.5 If the tag is detected outside of the desired area, decrease the LF Field strength by turning the adjustment counterclockwise until detection is limited to the desired area.Be aware that if the LF field reaches into adjacent floors it may cause tags onthose floors to be reported as if on the exciter floor.6 Continue moving between steps 4 and 5 to achieve the best compromise between a minimum number of dead spots, and limited detection.7 If a suitable compromise cannot be achieved, consider relocating the exciter and repeating the procedure.8 When you have successfully set the LF Field strength, turn off test mode on the transceiver and fix the exciter cables permanently in place.Tip: If the exciter is above a suspended ceiling, place a colored adhesive dot on theceiling tile to mark the exciter location. Consult facility management before placingthe dots.
