TMQ AP9 - NMEA and GPS Connections; NMEA Terminal Strip Configuration; GPS Data Input

TMQ AP9 Autopilot (V6.0 - 965) Page 31 of 51 31/1/2017
Caution: If the boat is carrying temporary “weather helm” as a result of sail trim or net
drag, realignment may not be necessary. Check BEFORE realigning.
NMEA Connection
The internal terminal strip T6 NMEA allows for the following connections:
1. GPS data input – for waypoint or GPS steering
2. Heading data input – as heading reference
3. TMQ proprietary data input and output – data for TMQ remote display for
example AP56
Note: + 10 V for power to remote display is taken from T5
NMEA Terminal Strip T6 - Pin Configuration
Pin 1 – Heading data – output NEG
Pin 2 – Heading data + output DAT1
Pin 3 – NMEA heading – input IN –
Pin 4 – NMEA heading + input IN +
Pin 5 – TMQ data – output NEG
Pin 6 – TMQ data + output DAT2
Pin 7 – GPS data – input IN –
Pin 8 – GPS data + input IN+
GPS Data Input
The AP9 pilot will accept two forms of GPS data in NMEA 0183 format as follows:
· GPS Plotter data – APA, APB or XTE + BOD for waypoint steering – pilot
display shows the bearing the pilot will steer to the waypoint (BTW on the
plotter).
· GPS data as heading reference – used when magnetic heading reference from a
compass is not available – pilot display shows the course made good over the
ground (COG) *
* Note: This is a special remote mode which has to be internally set into the
AP9 using a computer with Hyperterm program. Boat must be making
more than 2 knots true speed over ground for this method of operation.
