The field ‖ GPS NMEA output options ‖ is used to adjust how AIS-CTX will feed
position data to your application. If you use the excellent built-in GPS receiver also
for navigation or as a backup, ‖
Output GPS data every second ‖ should always be
selected. By default, AIS-CTRX CARBON will be set to ‖ Output GPS data every
four seconds ‖. ‖ Disable GPS data output ‖ should be chosen if you have an
application where you already have a GPS connected for navigation and application
cannot manage more than one GPS simultaneously (causes that one's own boat
jumps between the different GPS the receivers' positions). AIS-CTRX CARBON GPS
data should be shut off for Raymarine plotters . Intelligent applications can handle
several GPS signals at the same time by using primary- and secondary functionality,
and thereby have an automatic backup.
The field ‖
Alarm NMEA output options ‖ need only be used if you connect your AIS-
CTRX CARBON to a Raymarine system. AIS-CTRX CARBON transmits by default a
status message that all is like the will in accordance to the AIS Class B standard.
Because Raymarine units interpret the status message as an alarm and thereby fills
up its alarm buffer so quickly that it becomes full and stops the plotter, AIS-CTRX
CARBON can be set to only feed out live alarms by setting the alarm message in
position ‖
Output only active alarms ‖.
The field ‖ Safety related message text ‖ is not used.
All the modifications are applied only after the icon in the respective field ‖ Update ‖
has been clicked.
Figure 28 In the field [Commands] data from AIS-CTRX CARBON can be set to be output in different
ways.
