MX575:

There are two ways the MX575A DGPS compass can be connected to the MX51x, namely:

PORT3 as source of Positioning, Heading and ROT.

•

PORT1 (or 2) as source of Heading and ROT only

•

If the MX575 is used as a positioning and heading device on NMEA Port3, set Data input

port no to 3. This will automatically configure the MX575 to work at 19,200 Baud rate

and the HDG output will be set to 10 Hz on power up.

If the MX575 is used as a heading & ROT device only, set Data input port no to the port

number used (1 or 2) other than port 3. (See MX575 Satellite Compass Installation &

Operation Manual for details).

Set the constant MX575 Heading Offset (or bias) if any.

Datum - Current Position Calculation

This screen controls which datum the MX51x uses to display the position Lat/Lon. There

are over 100 datums to choose from. Appendix A provides a complete list of available

datums. You can enter an offset to WGS-84 if your specific datum is not provided for in

the MX51x. Use the Previous or Next softkeys or the cursor key to scroll through the list

until you find the datum you need. Highlight Escape then press ENT to go back to the

original datum displayed when you first pressed the EDIT key.

Depth - NMEA Input Control

This screen allows you to configure the depth unit (meters, feet, or fathoms) for the NAV

4 and TIDE 1 screens .

Depth information is accepted by the MX51x from the NMEA 0183 data sentence DBK,

DBS, DBT, or DPT on any input NMEA port. Refer to the Installation section of this

manual for hardware interface instructions.

Press the EDIT key and move the cursor to the Echo Sounder Connected line. Press the

ENT key to Change softkey to activate the input data options described below:

Depth Unit - select between meters, feet, or fathoms. This data field sets the depth unit

displayed in NAV 4 and TIDE 1, regardless of whether a sensor is connected or not.
