If the
All
box is not checked, you must define which particular reference station to
use by entering the reference station’s code. The
Code
entry box allows you to
specify which Differential Base Station will be used by the MX9400.
Once you have configured this dialog box and clicked the
OK
button, WinFrog sends
the configuration option messages to the MX9400. It may take a few moments for the
changes to take affect in the MX9400.

EDIT:
Adding the MX9400 device creates four data items: POSITION, PSEUDORANGE,
EPHEMERIS and TIMEDATE.
The MX9400 can provide WinFrog with an internally calculated (DGPS) position
message in one of two NMEA formats; GGA and GLL. This is added to the vehicle by
adding the
GPS,MX9400, POSITION
data item.
The MX9400 can also output raw Pseudorange and Ephemeris data for WinFrog to
calculate the position itself (using WinFrog’s GPS Calculations extension module).
This is setup by adding both the
GPS, MX9400, PSEUDORANGE
and the
GPS,
MX9400, EPHEMERIS
data items to the vehicle’s device list.
Additionally, a Time/Date message can also be output to provide WinFrog with more
precise timing information. Add the
GPS, MX9400, TIMEDATE
data item.
Typically, both options are desired; the internally configured position provides a backup
position to WinFrog’s more flexible Multi-Ref solution.
As per any and all devices, once you’ve added a MX9400 data item to a vehicle’s
Device list, it must be edited to suit the vehicle’s configuration. Note that not all data
items require this vehicle specific configuration.
Data item: GPS, MX9400, POSITION
The POSITION data item must be edited once it is added to a vehicle’s device list.
Highlight the data item in the vehicle’s device list, then select the Edit button. The
Configure Position dialog box appears as seen below.
