Data Export Items
The X-Plane version of
the 3 DOF motion driver runs with most recent versions up to X-Plane v10.
The driver uses flight data
exported by X-Plane using its UDP data export facility. The correct
data items must be defined in X-Plane for export, together with the
IP Address and receiving port number of the target PC (ie the PC the
motion driver is to run on).
To set the data items
for export start X-Plane v9.6 then go to Settings - Net Connections -
Inet 3 and set the "IP for Data Output" to the IP Address
of the motion driver PC. If the driver and X-Plane are running on
the same PC then set the IP Address to 127.0.0.1
Under the same
settings set the port number of the data receiver to 48001, this is
the default used in the .bff config file, you change this if
Tick the IP of data
receiver check box, then close the Net Connections window.
Now open the
Settings - Data Input & Output window and tick the first check
box on the following X-Plane v9.5/6 data items: 1, 3, 4, 13, 14, 17, 18, 21, 37, 66 and
127. This adds the selected data items to the UDP data packet.
On other versions of
X-Plane the network connection windows in which the IP address is
set may be different.
For X-Plane v10.0
the data items needed are: 1, 3, 4, 13, 14, 16, 17, 21, 37, 66, 127
For X-Plane v9.0 the
data items needed are: 1, 2, 4, 13, 14, 18, 37, 66, 124, 17, 21
For X-Plane v8.6 the
data items needed are: 1, 2, 3, 11, 12, 16, 34, 63, 119, 15, 19
Set the UDP data rate
at the bottom right of the window. This defines the frequency of the
data export. Ideally it should be marginally faster than the loop
rate of the motion driver. I suggest something like 40 sets/sec. If
the motion driver is routinely indicating that it is waiting for
data this data rate can be increased or the motion driver loop speed
can be decreased by increasing the length of the inserted pause using the
MD_Delay parameter in the motion driver .bff config file.
The data rates might
need some experimenting on your system. More powerful PC's will be
better able to support good X-Plane frame rates and motion driver
loop speeds simultaneously. If you can't achieve satisfactory rates
on an older PC then it may be best to run the motion driver on a LAN
PC so that it and the flight sim are not fighting for system
