3. Putting into operation
Connect the interfaces of the radio unit according to the chapters 2.2 Function elements and 2.3 Interfaces at the unit . See also
the circuit diagrams for the relevant applications in chapter 10. Circuit diagrams .
The WZ FSE 2-2 has been designed to operate with additional cooling. It is necessary to use a cooling attachment of sufficient
size or a cooling attachment and a ventilator.
If the unit is in transmit mode for a longer period without sufficient cooling, the integrated over-temperature protection will be acti-
vated. The unit will reduce the power level to approx. 30 ... 50 % without negative effect on all the other functions of the unit.
If this state should remain for more than 127 transmit cycles, the transmit mode will be completely disabled to avoid the destruction
of the unit. The unit is ready to use after it has cooled down sufficiently.
3.1 Basic mode when the unit has been switched on
The RS232 interface is deactivated when the PTT is activated after switching on the unit. The set memory corresponds with the
connection of the inputs SEL0 ... SEL4 (pins 12 ... 16). All the other parameters are according to the default setting of the unit.
3.2 Memory selection at the user interface
The WZ FSE 2-2 has 32 memories where you can store the transmit and receiver frequencies as well as the power level. The
memories will be assigned according to the parameterisation software or the terminal program supplied (CD-ROM).
The memory which is to be used for operation is selected via the inputs SEL0 ... SEL4 (pins 12 ... 16). The memory can be selected
by connecting the inputs to DIP switches or to the outputs of a microcontroller.
If the inputs SEL0 ... SEL4 (pins 12 ... 16) are not connected or connected to +5 V, the memory number will be set to 31. If the
inputs are connected to ground, the memory number will be set to 0.
The following table shows the connection of the inputs.
That means:
1: Input is not connected or not connected to +5 V.
0: Input is connected to ground (Pin 10).
