Configuration settings
The SeaTalk NMEA converter can be configured to meet the users requirements.
The configuration is made by sending a NMEA-like sentence. The settings are stored in an
EEProm.
The configuration sentence is :
$SNBSE,address,data
<CR><LF>
(Optionally a Checksum can be appended $SNBSE,address,data*XX<CR><LF>)
( SNBSE =
S
eatalk
NMEA
B
ridge
S
et
E
eprom )
Configuration settings a read, when the bridge gets switched on. So when you change the
configuration, you need to switch it off/on to activate the changes.
How to set the configuration :
Connect the bridge to a PC.
Open a terminal programm ( i.e. hypertern ) and set it to 4800 Baud, 8 Bit, no parity, no
handshake.
Type “ $xxx “ and press ENTER
Bridge responds with “ $xxx “. When you receive the $xxx, connection to your bridge is
ok. If $xxx does not appear after you pressed ENTER, check connection, setting of Com-
Port, Baudrate etc.
Example :
In this example, we configure the bridge, so that every incoming SeaTalk sentence
will be sent to the PC as $STALK,xx,yy sentence.
In your terminal programm enter
$SNBSE,0,1
The bridge will respond with
$SNBSE,0,1
Next time you switch the bridge on, it will send every incoming SeaTalk sentence to
the PC as a $STALK,xx,yy,zz … sentence.
