(from the receive
r) into a
digital
signal, detects the
ADS-B-frames in the signal,
and
sends
them to the
PC.

receive r to the network.
7 Switches
The decoder-layout has by default 4 switches to control the work of the
decoder.
Fig. 3 Default setting of the 4-position switch

Switch 4 - Remot e co nt rol
If s witch 4 is O N (and s witch 3 OFF), then the de coder ha s t o be
remo t e cont rolled by the adsbScope so ftware if you use a U SB
int e rface. The receiver works in USB mode (no data via WiFi). With USB
cable connected to the 4 pin connector (shown on schematics in Chapter
13) the receiver works just as microADSB-USB receiver. In this mode the
firmware of the receiver can be updated.
The swit ch 1, will have no effect. Aft er powe r-on or res et, the
decoder will not st art t o send dat a by it self; it will wait for a
com mand fro m the s oft ware .
If s witch 4 is OFF, t hen t he decoder starts t o s e nd dat a
immediately after powe r-on o r reset.
Switch 3 - s erial
If t he switch 3 is O FF, t hen t he USB-interfa ce will be used. But if
the swit ch 3 is ON, then the W i Fi-I nt erface will be us e d inst ead.
Switch 2 - Ti meTA G
If this swit ch is ON , t he n a precis e time code (for MLAT) will be
generate d by the decoder for each received frame. The adsbPIC decoder ti me t ag is base d o n a 12MHz clock. (So me ot her
decoders /re cei vers use a 20 MHz clock instead.)
The adsbScope software via USB ca n acti vat e the time tags by
software. If t his was done, then t he decoder will send ti me tags
eve n if t he s wit ch is i n o pe n position.The time tag can be used to
triangulate airc raft position i n collaboration with othe r decode rs .
If you don’t pa rti ci pate i n such a net wo rk, t he n you s ho ul d
deactivate t he ti me tags t o re duce t he l oad at the U SB/ W i Fi Interf a ce.
Switch 1 - DF1 7
This swit ch has no f unction, if switch 4 is ON .
If s witch 4 is OFF, then this swit ch controls whi ch frames are
reporte d to the PC. As long switch 1 is OFF, all receive d frames
will be reported t o the PC. But if swit ch 1 is ON, t hen only DF17,
DF18 and DF19 -frames will be t ransferre d.

second cli
ck activates the list of data again.
If
the box
has collected more then 20000 lines,
then
it will
be
erased
to
save
memory space.
The de coded cont e nt
of
the information is listed i
n the lower text
box.
If
the box

The software counts the number
of
ADS-B frames (data
packets)
per minute and displays
it in the lower right corner
of
the program
windo w and in the program
status
bar. Behind t his value is sh
own
(i

course
you can
choose
any other RAW -data-server, e.g.
receivers
with ad
sbScope
-Software
. You can
change
the IP-
a
ddr
ess
and the port number
of
the used RAW -dat a-server via
t he
net work-set up. Connections to other RAW-data
severs
have no
time limit.
11.1.5 Server ( decoded data )
The software contains
a
server
at port 30003. Via this server
the
received and deco ded information can be forwarded to multiple
clients.
The output format is
(hopefull
y) co mpatible
to RadarBox and SBS-
Basestation. However, I was
not able
to test this i
n detail
To start
the
server
one can click the left
of
the both gray network-server-
i
cons (right
of
the OSM icon). The
server is
st arted, a comme nt is
written in the upper log-window and the icon
gets colors.
Now
clients
can connect the
server
at port 30003. To deactivate the
server just click on the iconagai
n.
To test the running
server
you can start your internet-browser on
the same computer and type in http://localhost
