OziExplorer Configuration Setting

1. Go to the GPS tab on the Configuration dialog
2. Using GPS Make combo box select MLR
3. Using the GPS Model combo box select the model from the list. If your model is not on the list select the model as Other MLR.
4. Using the GPS Symbol Set combo box select the Symbol set to match the symbols in your GPS. If unsure leave it as it is as the most likely symbol set has already been selected.
5. Adjust the GPS Parameters to match the specification of your model of GPS. These parameters may be mentioned in the manual. If unsure leave them as they are as the most likely set of parameters has already been selected. MLR GPS receivers do not have Events (one of the parameters), this can be set to 500 so they can be used as markers on the map.
6. Set the GPS Upload/Download Datum to match the datum setting in your GPS.
7. Set the GPS NMEA Output Datum to match the datum setting in your GPS.
8. Goto the Comms tab on the Configuration dialog.
9. Select the Comm Port Number to match the one you are using on the PC
10. Set Parity to none
11. Set the Stop Bits - some models such as the FX series require 2 Stop bits, others such as the SP24 require only 1. Check your GPS manual for details.
12. Set the Upload/Download Baud rate to match the setting you have in your GPS. Note : This may always need to be set to 4800. For the "Fast" download methods the baud rate will be adjusted automatically by the software.
13. The NMEA Baud rate must be set the same as the Upload/Download Baud Rate.
14. Do not alter the AutoPilot settings unless required.

Special Instructions

Datums

The MLR expects and transmits the positions for NMEA strings and upload/download positions in whatever datum the GPS is currently set to. It is import therefore that in OziExplorer configuration the GPS Upload/Download datum and the NMEA Output datum be set to match the datum setting in the GPS.

The "Fast" download methods use "WGS 84" and this is automatically used in the software.

Baud Rates

The MLR always uses a Baud rate of 4800. In OziExplorer configuration set the GPS Upload/Download and the NMEA Baud rates to 4800. If required for the "Fast" download methods the baud rate is automatically adjusted by the software.

Upload/Download

These comments apply to the SP24 GPS but probably also apply to the other models.

To do any download from the unit you must have the GPS set to Menu Level 2 or 3 (at least for the SP24).

Not that the Symbol number is not included with a waypoint when downloading using the "Fast" method.

Waypoint and Route Download (from the GPS)

Some units have a high speed Waypoint download ability, there is an option on the MLR menu in OziExplorer called  "Get Waypoints from GPS (fast method)", if your GPS supports this option then no special settings in the GPS are required, download can be initiated by the software.

If you are downloading using the "Get Waypoints from GPS (nmea method)" then the GPS settings as described below are required.

The Data Output Format setting must be set to WPTS + ROUTES

After making this change in the GPS you must select the VALID option which is on the same screen as the FORMAT option.

Waypoint and Route Upload (to the GPS)

The Data Input setting must be set to NMEA

Track Download (from the GPS)

Some units have a high speed Track download ability, there is an option on the MLR menu in OziExplorer called  "Get Track from GPS (fast method)", if your GPS supports this option then no special settings in the GPS are required, download can be initiated by the software.

If you are downloading using the "Get Track from GPS (nmea method)" then the GPS settings as described below are required.

The Data Output Format setting must be set to TRACK

After making this change in the GPS you must select the VALID option which is on the same screen as the FORMAT option.

Track Upload (to the GPS)

MLR GPS receivers do not allow the track to be uploaded to the GPS.
