Device Alerts
The
AIS
WatchMate
will display device alerts (sentence $xxALR) received from other
instruments. These alerts may indicate operational status or problems. When a device alert
arrives, the message associated with it is displayed and you are given the opportunity to
send a confirmation back to the device that generated the alert. This tells the device that you
have acknowledged the situation. The specific types of alerts and messages are determined
by the attached devices. Please consult the manuals for the other devices for details about
each message.
When a message arrives, it is displayed automatically and the alarm is beeped briefly to
notify you. Press the
Confirm
or
Ignore
button to dismiss the message. If you press the
confirm button, an acknowledgment message (sentence $xxACK) is sent back to the device
containing the message ID.
An example message (the message content is supplied by the other device and will vary
from device to device):
NMEA Device Alert
ID: 003
HDG: HEADING SENSOR INACTIVE
