Multi-protocol stack RF module for building automation
The new module is designed for sensors, actuators and other home and building automation equipment. The module operates in the 868 MHz band, using Listen Before Talk (LBT) and frequency agility to reduce collisions. Up to 5 frequencies are scanned and automatically selected. One receiver can be linked with up to 64 transmitters, enabling very large RF networks. The fast acknowledge and retransmission feature ensure link reliability. Complete repeater functionality is also built in the protocol stack, and can retransmit messages in two hops. It can be used with S, A and E modes of installation. Among other features, the module offer automatic battery supervision and signal strength information. The RC1180-KNX2 surface-mount transceiver module measures 12.7×25.4×3.3mm. A UART interface is used for serial communication and configuration. An antenna is connected directly to the RF pin. The RC1180-KNX2 module is 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.
