The new family of pin-compatible modules meeting the KNX RF standard operating in the 868 MHz band with Listen Before Talk (LBT) to reduce collisions.
One receiver can be linked with up to 64 transmitters, enabling very large RF networks. It can be used with S, A and E modes of installation. Among other features, the modules offer automatic battery supervision and signal strength information.
The RC1180-KNX is a surface-mounted high performance transceiver module measuring only 12.7 x 25.4 x 3.3 mm, and can easily be integrated into any sensor or actuator. A UART interface is used for serial communication and configuration. An antenna is connected directly to the RF pin. The RC1180-KNX modules are certified for operation under the European radio regulations for license-free use. When used with quarter-wave antennas a line-of-sight range of 800 meter can be achieved.
