4 Installation and Wiring
Notes:
Before installing the antennas please read 5.1 Project Notes . The spacing of the antennas
in a gate depends on the antenna configuration.
If multiple antennas or gates are connected to different readers, a minimum clearance of
8 m must be kept between the antennas or gates. For shorter distances (1 m
– 8 m) the
readers must be synchronized. The synchronization of the readers (see application note
N10311-xe-ID-B.doc) is only possible in one of the Automatic Modes (Buffered Read,
Notification or Scan Mode). Below a distance of 1.5 m the antennas must also be shielded
from each other. Otherwise the read range will be significantly reduced. The antennas must
have a minimum distance of 20 cm to all larger metal parts! At a distance of less than 50 cm
between the antenna and metal parts the read range will be significantly reduced.
