probleme de transmission de données avec un multiplexeur

non , normalement la connexion sealtalk est a double sens in /out , je le vois apparaitre dans le tableau de controle mpx-config. il est en émission recpt.

c est une solution, mais le mien est trop ancien, sinon il faut que je passe par le pilote, c est pas génial ça risque de saturer donc de ralentir le rafraichissement du pilote et ses performances

le miniplex 3wi-2nk est donné pour être bi-directionnelle en sealtalk , j ai bien la sortie qui s affiche en st.

Combining Ports
It is s
ometimes necessary to combine an input
and
an
output
of the multiplexer to connect to an instrument. One
of the most common
cases is
the connection
between
a
GPS
and
the multiplexer. While some GPS receivers have
properly designed NMEA ports, many only hav

e an RS

232
port which is single ended with three terminals: TxD (data
out), RxD (data in) and Ground.
Figure
30
shows how to
connect such a GPS to the multiplexer.
SeaTalk
SeaTalk
®
is a proprietary protocol developed by Raymarine
®
. This protocol is used for communication
between Raymarine navigation instruments like the ST40, ST50 and ST60 series.
To be able to use these
instruments with commonly
available navigation programs or to feed their data into

other non

Raymarine instruments, the SeaTalk data
needs to be translated into NMEA. Even Raymarine
’
s own
navigation software, Raytech Navigator, needs this
translation.
The

MiniPlex

3
can be directly connected to a SeaTalk
network. It will translate all SeaTalk data required for
navigation into NMEA sentences. Input In
1
can be set to
SeaTalk mode (
“

SeaTalk

NMEA
”
) and should be
connected as shown
in
Figure
31
.
Figure
32

shows how to power the MiniPlex

3
from the
SeaTalk network.
The SeaTalk cable is connected to
In1/SeaTalk and at the same time t
he red wire
and
shield are connected to the power terminals of
the
multiplexer.
The multiplexer will both receive and send SeaTalk
data. Received SeaTalk data is converted into NMEA
0183 and NMEA 2000. Similarly, received NMEA 0183
and NMEA 2000 data will be converted and transmitted
on the SeaTalk bus.
