Safety precautions
Safety precautions
Please note!
• The units are not suitable for operation in rooms with an explosive atmosphere as well as damp environments or in
rooms with aggressive air or increased electromagnetic requirements.
• Mind the instructions for putting into operation.
• Both the casing and the antenna may become very hot (you may get burned) during sending operation. Provide for
sufcient cooling and air circulation.
• Installation of the antenna needs to be in accordance with the valid regulations and requirements for protection of
human beings within electromagnetic elds.
• Avoid to touch conductive parts of the unit.
• Do not open the device yourself, only permit repairs by the manufacturer.
ESD protection measures
Comply with the ESD protection measures according to DIN EN 61340-5-1/2 when opening the unit (potential
equalisation between body and ground of the unit via high-value resistance (approx. 1 MOhm) e. g. with a usual
wrist band.).
Read the user manual carefully to be able to use the wealth of features of the WZ FSE 2-2. You can nd further information
about this topic on our website http://www.fmncom.com.

1. General instructions
• In order to be allowed to operate the radio unit you must apply for a license at your local authorities and they will
assign you a frequency.
• Alle connection cables have to be equipped with an earth-connected shielding.
The connection cable for the antenna has to be equipped with a wave impedance of 50 Ω.
• The manufacturer recommends to mount devices in printed circuit board version into a metal housing.
• Corresponding mechanisms are to be used for detection of single bit errors during a data transmission (e.g. protocol
with creation of check sum).
• Only use antenna designated for the frequency range. Failure to observe this instruction will cause the approval to
expire and may result in legal action.
• The connected antenna has to be tuned to the working frequency of the radio set to get a maximum range.
• The use of an antenna that has not been tuned can lead to destruction of the radio unit.
• Provide sufcient cooling! (e.g. a heat energy of about 30 W has to be eliminated in case of a transmitting power of
6 W.)
• Further troubleshooting can be necessary in case of operation e.g. at switching power supplies.
• The compliance with the instructions for use and for putting into operation also belongs to the intended use. Every
other use is considered to be not intended. The manufacturer accepts no liability for any damages resulting from
such other use.

2. Product description
2.1 Description of device-specic 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 les from the PC to the WZ FSE to program all the parameters
• upload of les from the WZ FSE to the PC to view the programmed parameters via terminal program
• download of les 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

1) The input can be set to active LOW or active HIGH via the setting of the parameters; the PTT is set to active LOW by de-

2) Optionally available with similar to TTL (4,0 ... 5,0 V).
3) The duration of the display can be programmed via software.
4) The internal wiring additionally serves as EMV protection against radiation or emission.
5) The RXC (Clock) is only made available in receiving operation at the user interface at devices with FFSK modulator.
6) The data that is to be send has to be synchronous to the generated clock TXC at the version synchronous.
7) A synchronization of the data takes automatically place in the device at the version asynchronous. In this connection, the
norm V.24/V.28 (1 start bit, 8 data bit, no parity, 1 stop bit, asynchronous) is to be kept at the data input. Since an additional
loss of data is caused during sending at this version, the RTS signal after the last transferred data bit has to remain acti-
vated correspondingly longer (see chapter 11. Timing charts of the unit).
8) Two binary zeros and two binary ones (33 h, 66 h, 99 h oder cc h) have to be transmitted alternating to the synchronization
at devices with GMSK modulator. A change between a binary zero and a binary one (55h, AAh) should be avoided. This
sequence brings the quickest synchronization, but it can possibly lead to a higher fault rate at the data transmission.
The synchronization sequence has to have a length of at least 16 bit.
After the synchronization, you should send a start bit in order to mark the beginning of the data transmission for the opposite

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 sufcient
size or a cooling attachment and a ventilator.
If the unit is in transmit mode for a longer period without sufcient 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 sufciently.
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).

Note
If the WZ FSE 2-2 is disconnected from the supply voltage e.g. to realise low-power mode, make sure that no
power is applied to the user interface. Otherwise, you may encounter problems.

You can use any terminal program for parameterisation.
The manufacturer recommends to use the Hyperterminal program from Microsoft® Windows.
1. Start the Hyperterminal
2. Select the COM – port of the computer to which
the WZ FSE is connected.
3. Setting the COM properties
Bits per second: 9600 Baud
Data bits: 8 Bits
Parity: none
Stop bits: 1 Bit
Flow control: Xon/Xoff
Xon: ASCII-HEX 0x11 1)
Xoff: ASCII-HEX 0x13 1)
4. Click the Properties Icon
1) The ASCII-HEX values can be changed via software.

5. Click the Settings menu
6. Click the ASCII Setup
7. Make the following settings:
ASCII Sending
- Send line ends with line feeds
(Carriage Return, ASCII-Code Hex 0D)
- Echo typed characters locally
- Line delay: 0 ms
- Character delay: 2 ms
ASCII Receiving
- Append line feeds to incoming line ends
- Wrap lines that exceed terminal width
The terminal program is ready for use after the options have been conrmed.
If you use another terminal program, you have to make the settings similar to the Hyperterminal.
