6 Setting-up the ST4000+
Checking connections
Navigation interface (GPS, Decca, Loran)
If you have connected the ST4000+ to a NMEA navigator, check the
links by displaying the default data pages (
XTE, BTW and DTW):
• press
disp to display the first data page, and check that this page
shows the expected data
• press
disp again to check the other data pages
If the display shows dashes instead of data values, the cause could be
one or more of the following:
• a cabling error: check for an open circuit, short circuit or reversed
wires
• the navigator is not configured to transmit the required data
format
• the navigator is receiving signals that are too weak for reliable
navigation: refer to the navigator handbook for further action
Wind instrument interface
If you have connected the ST4000+ to a NMEA or SeaTalk wind
instrument, check the links as follows:
• Press
standby and auto together:
• the ST4000+ should display the Wind Vane mode screen, with
the locked wind angle and locked heading as shown
• if the ST4000+ is not receiving wind data, it will display a
NO DATA message: check the wind instrument and
connections
