5 Function

The ID tags are operated passively without battery. The energy required for operation is provided by the compact RFID device.

The energy is transferred via an electromagnetic wave. The receiving antenna takes up the wave and transforms it into voltage which supplies the data carrier with energy.

The radiated power is specified in ERP (Effective Radiated Power) and in EIRP (Effective Isotropic Radiated Power) for the devices. The respective value can be converted using the following formula:

P [dBm EIRP] = P [dBm ERP] + 2.15 [dB]

6 Installation

ATTENTION

Radiated electromagnetic field strengths

▷ The device sends ultrahigh frequency electromagnetic waves. It complies with the country-specific limit values for the public and workers.
▶ Disconnect the device in the vicinity of medical equipment.

6.1 Installation instructions for devices

Devices installed next to each other interfere if they are not configured correspondingly.
When mounting several RFID units adhere to the minimum distances between the systems.
Installing a unit in or on metal reduces the read and write distance.
Device performance can be affected if positioned in the immediate vicinity of powerful HF emission sources such as welding transformers or converters.

6.2 Installation instructions for ID tags

For installation in and on metal use the ID tags provided for this purpose.
Position the ID tag in the area of the sensing face. When doing so, the angle of aperture and the operating distance must be adhered to (→ Data sheet of the device).
Align the axes of the RFID device and the ID-TAG in the same way.

6.3 Avoiding interference

The device generates a modulated electromagnetic field in the following frequency ranges:

DTE80x: 865-868 MHz

DTE90x: 902-928 MHz

DTE91x: 920–925 MHz

DTE92x: 915–928 MHz

DTE93x: 918.4–923 MHz

DTE96x: 916.8–920.4 MHz

Interference in data communication is avoided if there are no other RFID UHF devices in the vicinity. If there are other RFID UHF devices in the vicinity:

▶ The mounting distances between the devices should be as large as possible.
▶ Use the RSSI filter.
▶ Use the devices in alternating operation.
▶ Switch the HF field of the device on/off.

The UHF field is attenuated if there are people or objects (cables, metal profiles, etc.) between the device and ID tag.

▶ Keep the area between the device and ID tag clear during reading or writing.

6.4 Mechanical design

1 Sensing face
2 Connections (can be rotated by 270° )

6.5 Mounting options

The device can be mounted without the accessories.

▶ For installation, please use the threaded sleeves on the back of the device.
▷ The required screws are not supplied with the device.

No liquid should be allowed to accumulate on the connected sockets and plugs.

▶ Mount the device preferably vertically, with the connections facing downwards.

6.6 Mounting distances

Operating mode	Distance side (A)	Distance front (B)
Reading and writing at 100% transmitting power (simultaneous operation)	>0.6 m	>0.6 m
Reading and writing at 100% transmitting power (alternating operation)	>0.3 m	>0.3 m

Interference in data communication is avoided if there are no other RFID UHF devices in the vicinity. If there are other RFID UHF devices in the vicinity:

▶ The mounting distances between the devices should be as large as possible.
▶ Use the RSSI filter.
▶ Use the devices in alternating operation.
▶ Switch the HF field of the device on/off.

6.7 Positioning of the ID tags
