Chapter 3: Commissioning & Setup 33Startup problems• If the Pilot Controller does not beep or the display is blank, switch off the power,then check the fuse/circuit breaker and the SeaTalk fuse in the SPX Course Com-puter.• If the display shows the SEATALK FAIL or NO PILOT alarm message, check theSeaTalk connections.• If the STANDBY screen does not display a live compass heading, check the sensorconnections.Step 2 - Check data connectionsPilot controllerCheck the SmartPilot controller links as follows:• With on the Pilot Controller switched on, check that the Pilot Controller displayshows STANDBY.• If this does not happen or if the display shows NO PILOT, check the cabling andconnections between the Pilot Controller and the other units.SeaTalk and NMEA GPS or ChartplotterIf you have connected the SPX-5R Drive system to a chartplotter or GPS (e.g. viaNMEA or SeaTalk), check the links by displaying the default navigation data pages onthe Pilot Controller:1. Press disp to display the first data page (XTE), and check that this page shows theexpected data.2. Press disp again to check each successive data page (BTW, DTW etc)If the display shows dashes instead of data values, ensure:• The GPS or chartplotter is switched on and transmitting active waypoints.• The GPS or chartplotter is configured to transmit the required data format.• There is not a cabling error. Check for open circuit, short circuit or reversedconnections.Other NMEA connectionsTo check other NMEA connections, you will need to set up the appropriate page ofdata using Dealer calibration mode.Data pages are viewed by pressing the disp key (when in Standby or Auto mode).For details of supported NMEA sentences, see Appendix 1: NMEA 0183 sentencesStep 3 - Checking rudder bar operating senseIf a rudder reference transducer is fitted, check the rudder bar operating sense asfollows:1. Turn the wheel manually to starboard.2. Check that the rudder bar on the controller display moves to starboard.If the rudder bar moves the wrong way:i. Turn off the power.ii. Reverse the red and green wires connected to the RUDDER inputs on theSPX Course Computer.iii. Switch on the power and re-check.
