Step 2 - Check the SeaTalk and NMEA connections
SeaTalk connections
If you have connected the ST7001+ to other SeaTalk instruments or
control units, check the links as follows:
1. Select display lighting level 3 (
LAMP 3) on one of the SeaTalk
instruments or control units.
2. The ST7001+ should immediately switch on its display lighting:
• if the lighting does not switch on, there is a fault in the SeaTalk
cabling between the ST7001+ and the other units
NMEA navigator connections
If you have connected the ST7001+ to an NMEA navigator, check the
links by displaying the default navigation data pages (
XTE/BTW/DTW):
• press
disp to display the first data page, and check that this page
shows the expected data
• press
disp again to check each successive data page
If the display shows dashes instead of data values, the cause could be
one or more of the following:
• navigator not switched on or not transmitting an active waypoint
• cabling error: check for open circuit, short circuit, reversed wires
• navigator is not configured to transmit the required data format
Wind instrument connections
If you have connected the autopilot to an NMEA or SeaTalk wind
instrument, check the links by pressing
standby and auto together:
• the ST7001+ should display the Wind Vane mode screen, with the
locked wind angle and locked heading:
• if nothing happens when you press standby and auto together,
the ST7001+ is not receiving wind data: check the wind
instrument and connections
