Chapter 2: SmartPilot Commissioning 21
NMEA navigator connections
If you have connected the SmartPilot to a NMEA navigator, check the links by
displaying the default navigation data pages on the SmartPilot controller:
• press disp to display the first data page (XTE), and check that this page
shows the expected data.
• press disp again to check each successive data page (BTW, DTW etc)
If the display shows dashes instead of data values, check for the following:
• the navigator is not switched on or not transmitting an active waypoint
• a cabling error. Check for open circuit, short circuit or reversed wires
• the navigator is not configured to transmit the required data format
Wind instrument connections
• If you have connected the SmartPilot to a NMEA or SeaTalk wind instrument,
check the links by pressing standby and auto together:
• the SmartPilot should display the Wind Vane mode screen, with the locked
wind angle and locked heading.
• if the controller does not display WIND mode, the SmartPilot is not receiving
wind data. Check the wind instrument and connections.
Step 3 - Check the autopilot operating sense
Check the rudder position sensor
1. Turn the wheel manually to starboard.
2. Check that the rudder bar on the controller moves to starboard.
If the rudder bar display moves the wrong way:
i. turn off the power
ii. reverse the red and green wires connected to the RUDDER inputs on the
SmartPilot computer
iii. switch on the power and re-check
