Time of message is UTC time if the Device has received the time from the NMEA 2000
network, otherwise it is the time from Device start.
The format of messages sent from application to Device is the same, but without time
and direction field. Outgoing messages must end with <CR><LF>. If the message
from application is accepted, passes filters and is transmitted to NMEA 2000,
it will be sent back to the application with ‘T’ direction.
For example, the application sends the following sentence to the Device:
19F51323 01 02<CR><LF>
When this message is sent to the NMEA 2000 network, the Application receives
an answer like:
17:33:21.108 T 19F51323 01 02<CR><LF>
The Application will get no answer if the message filtered or the message syntax
is invalid.
The format of NMEA 2000 messages is available in Appendix B of NMEA 2000
Standard, which can be purchased on the site
www.nmea.org
