Configuration commands

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 = SeaTalk NMEA Bridge Set Eeprom )

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 using the USB port.

Open a terminal program ( 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

established and working properly. 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 program 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.

How to read current setting

In your terminal program, enter $SNBSE,Function-Id

The bridge will respond with $SNBSE,Function-Id,data

→ For a list of function ID's and values – see page 22.
