2.1 KL6021-0023 - Introduction
Fig.1: KL6021-0023 – serial interface terminal for the connection of the KL6023 wireless adapter
The KL6021-0023 serial interface connects the wireless adapter via an RS485 signal. The KL6023 wireless
adapter operates as an EnOcean radio receiver and receives the radio signals from EnOcean sensors.

Product overview
2.3 KL6023 - Introduction
Fig.2: KL6023 - Wireless Adapter for EnOcean radio technology
The KL6023 Wireless Adapter receives signals from battery-less sensors with EnOcean technology. These
signals are converted by the Wireless Adapter to a RS485 signal and directly processed further by the
KL6021-0023 serial Bus Terminal. With a radio signal range of at least 30m, the wiring of buildings can be
simplified significantly.

KL6021-0023 and KL602310 Version: 2.0.0
Product overview
The status LEDs of the Wireless Adapter are helpful during commissioning. The LEDs indicate all telegrams
they receive as faulty or faultless. With a maximum distance of 300m between the receiver and the Bus
Terminal station, it is possible to place the receivers at any radio-technically favorable location within a
building. The system does not stipulate a maximum number of transmitters per receiver unit. In practice,
between 25 and 100transmitters per receiver are used.
