Operator's Manual
There are several special case screens which provide added support.

xxx loads the port by - The NMEA 0183 standard limits the port
baud rate to 4800 bits per second. It is impossible to turn on
every NMEA 0183 data record on one port in the receiver at a
once per second output rate, due to the NMEA standard limi-
tation. xxx loads the port by tells you how much throughput
capacity is required to send the selected data record out the
port (where xxx is the NMEA data sentence identifier). If you
change the Output Rate, xxx loads the port by: value will
adjust to reflect the change after you move the cursor to the
next line. This is a very helpful tool to ensure that you don't
loose 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 avail-
able from the receiver at a once per second output rate at one
time. The Total load is counter will help you maximize the port
usage on the receiver. It monitors the total throughput capa-
bility of all the output 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.
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 equipment may require this
data record as R01. The receiver allows you to configure the
ID either way (R00 is the default).
