Most:

NMEA Version - Some of the NMEA 0183 records are no longer supported by version

2.3. However, you may have an autopilot, plotter, or other older model equipment

that does not support the newer version of the NMEA 0183 standard. The MX51x

provides you the flexibility to interface using older versions of the NMEA standard

to support these devices.

Decimals In Lat/Lon - The software allows you to select from 2 to 5 decimal places in

records containing position or waypoint information.. The MX51x provides you the

flexibility to match the expected input on these devices.

Decimals In BRG or HDG - The MX51x allows you to select from 0 to 1 decimal places in

records containing bearing information.

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

limitation. 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 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 is” counter will help you maximize the port

usage on the receiver. It monitors the total throughput capability 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.

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 equipment may require this

data record as R01. The MX51x allows you to configure the ID either way (R00 is

the default).
