6.1 Possible Interference Sources
*
Warning:
It is possible that external interference sources will influence the read range, e.g. monitors,
switching power supplies, power cables parallel to data cables, mounting on metal etc.

Note:
With growing distance between reader and interference source the influence decreases.
LCD monitors have a minimal influence on the read range. In particular the reader should be
mounted on non-metallic material, such as plastic or wood. Metal screws (M6 - ISO 1207, 4762
or 7045) for mounting the reader have an insignificant influence on the read range.
Use only regulated power supplies. deister electronic GmbH offers suitable power supplies.
To reduce the influence of external electrical interference, connect the cable shield to ground
(GND) of the power supply.
