2.1 Description of device-specific features
The radio unit WZ FSE 2-2 is a radio transmitter / receiver available as OEM version (PCB). It has been designed for voice and
data transmission in the 2 m band.
Because of its small and compact design, the WZ FSE 2-2 is suitable for integration in data systems where it is important to
achieve high data rates over long distances.
In connection with a GMSK modem, data rates up to 9600 bps and with an FFSK modem, data rates up to 2400 bps can be
achieved.
The radio unit complies with the requirements of the German VDV (Verband Deutscher Verkehrsunternehmen - Public transport
companies association) and can be used within the public transport sector.
Features of the WZ FSE:
•
setting via an extended command interpreter in the terminal program
•
32 memories - transmit channel, receive channel and power level can be programmed separately
•
memory selection via hardware or software
•
automatic control of the power level in case of mismatching; this can be programmed via software
•
debouncing time for the hardware selection lines; the time can be programmed via software.
•
protection of the unit via automatic control of over-temperature; this can be programmed via software
display of the over-temperature (e.g. you can connect an LED including a pre-resistor at the user interface, for further infor-
mation see chapter
7.3 Instructions in the case of malfunction )
•
display of the analogue RSSI value (signal strength) via terminal program; the measurement signal of the analogue RSSI
value is available at the user interface
•
display of the error status of the unit; it can be programmed via software how long the error status is displayed (e.g. you can
connect an LED including protective resistor at the user interface, for further information see chapter
7.3 Instructions in the
case of malfunction )
• download of files from the PC to the WZ FSE to program all the parameters
•
upload of files from the WZ FSE to the PC to view the programmed parameters via terminal program
•
download of files from the PC to the WZ FSE for loading new software to the WZ FSE
Parameters of the programming software:
•
setting the output mode (normal or extended)
•
setting the software handshakes (Xon/Xoff or NO)
•
display of the commands via echo
•
setting the RS232 baud rate (1.2 kBaud to 115 kBaud)
•
setting the PTT (active HIGH or active LOW)
•
activation of the PC interface during transmitting operation
•
restoring the factory default of the WZ FSE
•
setting the waiting time and the blinking periods of the ERROR output of the user interface
Tolerance band for logical levels:
level min. max.
High Output 4,0 V 5,5 V
Low Output 0,0 V 0,9 V
High Input 4,2 V 5,2 V
Low Input 0,0 V 0,5 V
