The
radio modem WZ DFM 10/430S is the logical extension of
our existing radio modem line. The integrated frequency
synthesizer and signal strength output make it perfect for
flexible and fast solutions.
Opens up new markets in industrial applications
Small and light - the FMN radio modem WZ DFM 10/430S is
ideal for mobile and stationary use in radio data systems. Data
rates up to 19200 baud open up new market segments in industrial
applications.
High data rates and transmission range
GMSK modulation permits data rates up to 19200 baud with 50 kHz
channel spacing. In comparison with other modulation methods,
like FFSK, GMSK modulation offers a higher transmission range
and better transmission security.
Free of license and no registration fees
No registration fees need to be paid for the WZ DFM 10/430S.
It is license free and can be used without any permission in
Germany.
TTL or RS232 interface
The WZ DFM 10/430S is controlled via TTL interface. The
interface offers some special 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 standard
terminal program or the software supplied. In analogy with the
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 10/430S uses a frequency synthesizer and
covers the frequencies from 433.100 MHz to 434.750 MHz.
Frequency switching is controlled by software, 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 10/430S 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.
The WZ DFM 10/430S has been successfully integrated in a
variety of customer applications. |
