IUH-F192-V1-*
Installation
4.3.2 Minimum Distances
When positioning the read/write device, please observe the minimum distances. The lateral
distance between the read/write device and metals or liquids should be at least 50 cm. The dis-
tance between the read/write device and the ground should be at least 50 cm.
Figure 4.2
During simultaneous operation of several read/write devices, only one read/write device may
ever communicate with a tag at any given time. When arranging the read/write devices, make
sure that the measurement ranges do not overlap. You can enlarge or reduce the size of the
measurement range by changing the transmitting power. Determine the measurement range of
each read/write device at the mounting location.
4.3.3 Polarization
The polarization of the electromagnetic wave emitted by an antenna depends on the electro-
magnetic field component and the position of the antenna. Polarization can be either linear or
circular. To achieve the maximum detection range for a UHF system, the polarization of the
read/write head must match the polarization of the tag. Refer to the relevant data sheet to find
the polarization of the tag.
• Linear polarization: When an electromagnetic wave has linear polarization, the direction
of the vector of the electromagnetic field component is constant. Linear polarization can
be either vertical or horizontal. This characteristic depends on the position of the antenna.
• Circular polarization: When an electromagnetic wave has circular polarization, the vector
of the electromagnetic field component rotates around an axis parallel to the direction of
emission. The rotation of the antenna around the transmission axis has no effect.
The integrated antenna of the IUH-F192-V1-* read/write head has dual linear polarization. The
read/write head operates in combined mode by default. In combined mode, both horizontal and
vertical polarization are used for each read/write access. This increases the reading reliability
of tags with an unknown location in the room.
If the orientation of the tags is known, you can optimize the access time by setting a fixed polar-
ization. To do this, you can switch the polarization to horizontally linear polarization or vertically
linear polarization via the IDENTControl control interface software. The linear polarization plane
refers to the preferred mounting direction with the cable connection mounted vertically down-
wards.

Note
During mounting, take into account how the read/write devices may cause interference with
each other. The further the transmission channels of the read/write devices are from each
other, the lower the risk of interference.
