Using the Web Server
– To define the output of an NMEA message on a given
port, you just need to select the message type from the
Message drop-down list, the output port from the Output
drop-down list, then enter its output rate, in seconds,
in the
Rate field, and finally click on the Add button.
The new message definition will then appear as a new
row in the table on the right. Note that for messages
PTT, TTT and XDR, you don’t have to define an output
rate, due to the very nature of these messages.
– To change the definition of an existing message (port,
rate), select the corresponding row in the table. This
populates the three fields on the left with the
definition of that message. Edit the port and/or rate
and then click on the
Modify button to save your
changes.The table row is updated accordingly.
Note that depending on the current selection on this
page, the button located underneath the three fields
on the left may be either grayed or with a different
label (
Add or Modify).
– Deleting a message definition can be done by simply
clicking on the corresponding “trash” sign in the Clear
column on the far right. This deletes the table row.
– There is also a Clear All button underneath the table
that allows you to delete all the message definitions
from the table in one click.
