KNX-RF Multi Transceiver Module
Product Description
The RC1180-KNX2 RF Transceiver Module is a compact surface-mounted high performance
module with embedded Wireless M-Bus protocol. The module has a UART interface for serial
communication and configuration, and a one-pin antenna connection. The module is pre-
certified for operation under the European radio regulations for license-free use and
measures only 12.7 x 25.4 x 3.3 mm with shielding. When used with quarter-wave antennas a
line-of-sight range of 500-600 meter can be achieved. The RC1180-KNX2 meets the KNX-RF
specification 5 channels in the 868 MHz frequency band.

- Page 2 KNX-RF Multi Modem The standard RC1180-KNX2 module acts like a KNX-RF Multi modem with a UART interface. The embedded protocol transmits and receives the KNX-RF data packets based on application messages from an external source (the meter or the concentrator). The module is configured through its UART interface using a simple command set.

Alternatively the RC1180-KNX2 may be powered form a separate voltage regulator. This will ensure that potential switching noise is filtered out from the power supply to the RC1180-MBUS.
