Panel Reader Tuning

The Panel Reader is factory tuned for optimum performance in the absence of nearby metallic

objects. In some mechanical installations, mounting the panel reader near stationary metal

objects is unavoidable, and sometimes it becomes necessary to install metal shields behind the

Panel Reader in order to limit its effective read zone. In these instances, the presence of metal

can detune the Panel Reader’s antenna circuit, and compromise performance. The easiest way

to determine this is to simply measure the Panel Reader’s reading distance with and without

metallic object’s present.

When it has been determined that a metal object does compromise the read distance

performance, it may be possible to retune the Panel Reader. In order to do this, please refer to

the separate tuning document supplied with your reader.

Panel Reader Synchronization

Please consult Allflex before attempting synchronization. When multiple Panel Readers are

installed nearby one another, in some instances there may be mutual interference induced

among them due to their independent exciter signal timing. If Panel Reader performance is

compromised or inhibited when a second Panel Reader is activated, the user should employ

the wired synchronization option. In order to synchronize the control boxes for both readers

must be upgraded to include a synchronization board. Both boxes then need to ne joined

using a specific cable. One reader unit must be configured as a master unit, and all others

must be configured as slave units, using Configurator®. Detailed instructions must be

sought from Allflex for the synchronization option.
