ensure that you don’t lose data due to lack of throughput
on the data port.
Total load is - Due to the throughput limitation of the
NMEA 0183 standard, you can not turn on all of the
output records available from the receiver at a once per
second output rate at one time. The “Total load” counter
will help you maximize the port usage on the receiver. It
monitors the total throughput capability of all the out-
put records that are currently turned on. If you go over
100% and you require all of the data records that are
currently turned on, try reducing the Output Rate for one
or more of the less critical data records. Continue this
process until the Total load is 100.0% or less.
There are several special case screens which provide
added support.
Rnn - Active Route Data Record:
The NMEA-0183 standard allows you to output the active
route with an ID sentence that begins either as GPR00 or
GPR01. Some of the equipment you might interface may
require this sentence to outputs R00 and other equip-
ment may require this data record as R01. The receiver
allows you to configure the ID either way (R00 is the
default).
WPL - Waypoint Location Data Record:
The receiver outputs all of the waypoints in the active
route. If you want to output the complete Waypoint
Bank, simply high light the Send All softkey then press
ENT from the NMEA WPL screen.
