The radio modem WZ
DFM 5/868 is the logical extension of our existing radio
modem line. The maximum RF- output power of 5 mW as well as
frequency synthesizer and signal strength output are ideal for
flexible and fast solutions.
Opens up new markets in industrial applications
Small an light - the FMN radio modem WZ DFM 5/868 is
ideal for mobile and stationary use in radio data systems. Data
rates up to 76800 baud open up new market segments in industrial
applications.
High data rates and transmission range
GMSK modulation permits data rates up to 76800 baud. In
comparison with other modulation methods, like FFSK, GMSK
modulation offers a higher transmission range and better
transmission security.
TTL or RS232 interface
The WZ DFM 5/868 is controlled via TTL interface. The
interface offers some additional signals to optimise the
transmission characteristics.
In combination with the controller WZ DFC, the modem features an
RS232 interface for programming and data transmission.
Parameters can be set via the controller WZ DFC or plug-in
jumpers. In analogy with AX.25 protocol secure data transmission
is possible. Data can be transmitted in transparent and
broadcast mode.
Frequency synthesizer and signal strength output
The WZ DFM 5/868 uses a frequency synthesizer and
covers the frequencies 869.525 MHz and 869.850 MHz. Frequency
switching is controlled by plug-in jumpers or DIP switch (with
controller WZ DFC). This feature offers flexible and fast
solutions.
The signal strength output permits an indication of the signal
strength at each site. By using this signal, the optimal
installation site can easily be found as well as topographical
data like illumination and coverage can be gained. A combination
of both features (frequency synthesizer and signal strength
output) enables the user to build up cellular networks for
professional applications in the private mobile radio sector.
Applications for many purposes
As a classic OEM product, the WZ DFM 5/868 is ideal for
integrated applications. Hence, solutions for hand terminals,
PLC applications, logistics, mobile data acquisition and several
monitoring tasks can be realized. We offer both OEM versions
with TTL interface or with controller and RS232 interface as
well as IP 65 housed units. |
