IUH-F192-V1-*
Installation
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
polarization. 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 downwards.

Connection
Connect the read/write head to the IDENTControl control interface using a shielded connection
cable (see chapter 2.5.3). Ensure that the shield is end-to-end to avoid EMC interference. (see
chapter 3.5)
Warning!
Incorrect electrical connection
Damage to the device or plant caused by incorrect electrical connection.
Check all connections in the plant before commissioning the device.
After connecting the supply voltage to the control interface, the POWER LED lights up green on
the device. If the LED does not light up on the device, the power supply is not connected
correctly.
