  • Page 4: General Description

    1. GENERAL DESCRIPTION The multifunctional receiver modules RCM 110 and RCM 120 are used to receive and to process telegrams generated and transmitted by EnOcean radio transmitters. These modules can be easily integrated into control and switching units for the implementation of different application-specific system solutions.

  • Page 5: Typical Applications

    1.2 Typical Applications • Building installation • Industrial automation • Consumer Electronics The RCM modules are part of a powerful RF system solution from EnOcean for operation and control applications. Because transmitters self-powered batteries), maintenance-free RF systems can be implemented.

    Positioning and choice of receiver and transmitter antennas are the most important factors in determining system transmission range. The RCM 110 and RCM 120 receiver modules are supplied with a soldered whip antenna as a standard. This antenna enables a very compact receiver unit with good radio reception characteristics.

    3.10 FCC/IC Approval Requirements Because of the very low radiated field strength on average, the 868.3 MHz EnOcean radio technology can be approved in the USA and in Canada. In the US approval of receivers is not necessary in general. On a voluntary base an US representative can last out a "Declaration of Conformity"...
