4. System implementation

SEMI industry uses hdx LF RFID technology. This particular method relies on field gaps, where the RFID field is switched off.

In this gap the transponder answers with its code. This method has the advantage of high read range in laboratory

conditions. However, in a EMV polluted environment, read range of hdx transponders is significantly reduced as even low

noise signals have a direct impact on read range.

Therefore it is absolutely mandatory for system integration to make sure that power supply for ACM 9 and therefore ARE i9

is absolutely stable and clean with no noise. It is recommended to use linear power supplies rather than switching power

supplies. All other applications benefit from this as well.

Please make absolutely sure that ACM 9 communication module is properly grounded. This ensures proper functionality of

the entire system comprising of ACM 9 and ARE i9. Please see chapter 2.1.2 for details on grounding of ACM 9.

Grounding can be achieved by grounding DIN hat rail, as clamp on backside of ACM 9 is connected to ground. Alternatively

the grounding pin on the backside of ACM 9 can be used to achieve this.

ACM 9 is typically mounted on a metal DIN hat rail in a metal electrical cabinet. There is no influence of metal on

performance of ACM 9 and therefore nothing to watch out for.

It is recommended to mount ARE i9 onto a non-conductive surface. However, ARE i9 is designed to work when mounted on

metal as well. There is a slight decrease in read/write range when compared to mounting on non-conductive surfaces, but in

most cases the read/write range will still be plenty for the application.

Frequency converters used in electronic motors are a source of significant EMV noise. Make sure to stay away as far as

possible from those frequency converters when designing spots where ARE i9 is to be used. Noise from frequency

converters significantly reduce read range of ARE i9.
