  • Page 14: Radio Transmission

    Functional Description 10/2003 Radio transmission The SRIF 2002 comprises all necessary functions for the transmission of digital data in the 5.8 GHz range in transmit and receive mode. It is possible to set 127 frequencies (channels) independent of each other. The channels can either be programmed via an additional asynchronous interface (UART protocol: 4800 Baud;...

  • Page 15: Parameterization Via The Parallel Interface

    10/2003 Functional Description The SRIF 2002 communicates via a serial asynchronous interface (UART protocol). The transfer rate has to be preset by the user. Transfer rates of 9600, 19200, 38400, 57600 and 115200 can be set via the quadruple DIP switch of the SRIF 2002 (see Figure 1, page 11).
  • Page 16 Functional Description 10/2003 The coding switch to be connected short-circuits the selected address lines with the reference line (inverse logic !). Due to the missing eighth address line, the settings on the coding switch starting from 8x are interpreted as entries starting from 0x. Operating Instructions SRIF 2002 Page 16 of 33...

  • Page 21: Notes On The Radio Operation

    10/2003 Functional Description Notes on the radio operation Conditions for the radio path A radio path usually exists between a stationary unit (e.g. SDA or TRX245) and a mobile unit (e.g. MPS, HT, MDA, BA). Various physical quantities influence the signal propagation on the radio path. In order to achieve a radio transmission which is as interference-free as possible, the total of all of the physical parameters should be as good as possible.
  • Page 22 Functional Description 10/2003 ● Radio path: The radio path in open space is the most optimal one. Stationary obstacles (e.g. walls or metallic objects) limit the transmission range and movable or smaller objects (also humans) also influence the radio path. Since the radio transmission in this frequency range is not only carried out directly, but also via reflexions, other paths are also possible (multipath propagation).
