Settings for the DIP switch
The SRIF 2002 communicates via an asynchronous serial interface (UART
interface). The transfer rate has to be preset by the user.
Transfer rates of 9,600, 19,200, 38,400, 57,600 and 115,200 baud can be set via
the quadruple DIP switch of the SRIF 2002. Data communication is always
8E1 (8 data bits, even parity, 1 stop bit).
The SRIF 2002 carries out the setting of the DIP switch after every power-on reset.

The typical setting / factory setting is the baud rate 57,600.
Note
This presetting can be overwritten with the help of the additional asynchronous
serial interface (UART protocol: 4800 baud; 8N1). The procedure is described in
Chapter 3.3, page 17).
ECOS products such as the MPS, the hand-held terminal, or similar products use
the serial parameterization to overwrite this switch setting.
The transmitting power of the radio module can be reduced via the S4 switch.

Please refer to Technical Data in Chapter 6, page 29, for the corresponding
transmitting power.
The typical setting or factory setting is “Full transmitting power”.
