MX500 NMEA Out Menu
Scroll down the list using the cursor key to the desired
NMEA 0183 sentence. Highlight the Change softkey then
press ENT to select On.
Highlight the Details softkey then press ENT to view the
characteristics for the NMEA record you select. If you
notice that the top of some text is cut off by the Capacity
Needed window, this indicates that there are more selec-
tions available than can fit in the window. Use the cur-
sor key to scroll down the list. Each record is controlled
separately. Generally speaking, the following controls are
available to you for most or all of the records:
Checksum On or Off - NMEA 0183 version 2.1 and above
requires that the checksum is present. Versions 1.5 and
2.0 do not require the checksum. The receiver provides
you the option of turning the checksum on or off to pro-
vide flexibility in interfacing.
Output Rate - maximum once per second, unless the
Multi-Hertz option is installed. Refer to the Total Load Is
section which follows.
All position information contained in any data record
is output in the local datum selected in CFG/Position;
except GGA, which provides a selection in the Details
screen to output in either WGS-84 or the datum selected
in CFG/Position.
