waypoint) when Yes is selected. It also causes the NMEA data
records of APA, APB, and XTE to change their reported status of
Valid to Invalid when you reach the waypoint of the current leg.
This tells the autopilot not to use the data from the receiver. When
the alarm is canceled, which requires your highlighting of the
Can-
cel Alarm softkey then press ENT (displayed during the alarm con-
dition), these data fields will revert to valid data and the autopilot
will accept the receiver data again.
This is provided as a safety
feature so that the boat does not turn toward a new direction

2 - NMEA 0183 Output Data Control
These screens set the specific NMEA 0183 output record parameters
as well as the port control. The default setting is
No . When this selec-
tion is changed to Yes , you can turn on individual data records. Refer
to the installation manual of the device you interfaced with the re-
ceiver to determine which output records are required. Refer to the
Appendix F of this manual for receiver hardware interface information.
MX500 Model - has two user NMEA ports available, two antenna
ports (NMEA3 & 4) dedicated to the MX smart antenna, and
one Local Area Network (LAN) port.
Note: Pre plan your interface requirements to ensure all of your
interfacing needs are met. All NMEA Ports are RS-422
electrically. We recommend using these ports to inter-
face to a computer or other “single ended” interface.
The default condition of each port is Off . When you want to output
data on a NMEA port, scroll down the Item menu to the appropriate
NMEA Out port number and change Port Active to Yes . In doing so,
the receiver will display all available NMEA 0183 output sentences.
