The motion driver configuration settings are held in a .bff configuration file which is selected and opened when the motion driver is run. There are a wide range of parameters that can be configured to affect the basic configuration and motion output by opening and editing the file in a text editor (eg NotePad).

The detailed pitch, roll, and heave settings and the range utilisation parameters can also be set through the motion driver window using the P, R, H and M "settings" buttons in the main window. These settings windows also provide more detailed pop-up tool tips for each of the parameters.

The Basic, Platform Geometry, Hot Button/Key, Runway Effect and other non cue related settings should be made directly in the .bff file before the motion driver is run. Many settings can also be made user the Driver_Setup .exes in the motion driver folder.

NOTE some parameters have different uses for different platform types - these are indicated below. The configuration parameters are:

BASIC SETTINGS

Rig_Type=1  Platform Type, =0 for independent DOFs, =1 for 3 point support coupled actuator drives.

Act1_Rev=0  For 3-pt rigs with non-reversible feedback encoders - software drive direction reverse on individual 
Act2_Rev=0  channels. (No effect when Rig_Type=0).
Act3_Rev=0

Mode=BIN  to define motion cue output mode, must be BIN, HEX2, MEM, GAL, SCN5, POLO or NONE for the V2 motion driver.

Port=COM*  set the output COM port number, COM1, COM2 etc for modes which use a COM port.

Baud=115200 serial output baud rate. Note for MEM output use with the PID Servo Controller the controller's baud rate is set in the PID26.cfg file.

Nsets=100  Number of data sets to run before sending motion data to output. This setting allows the driver to execute a number of calculation loops to allow the noise and washout filters to stabilise before starting to export data. The main function buttons on the driver will remain disabled until the loops have been executed.

FALim1=200 For Rig_Type=0 Lower bound of movement range within the 1-255 scale, for Rig_Type=1 the actuator working stroke length.

FALim2=100 For Rig_Type=0 Upper bound of movement range within the 1-255 scale, for Rig_Type=1 the %tage of stroke the pitch cue can use.

LALim2=50 For Rig_Type=0 Upper bound of movement range within the 1-255 scale, for Rig_Type=1 the %tage of stroke the heave cue can use.

Roll_Rev=1 Reverse roll output sense, =0 No, =1 Yes

HEAVE CUE SETTINGS (See the pop-up tool tips in the driver H settings windows for more details)

VaScaleg=1.0 Scaling factor to be applied to raw vertical accelerations for heave calcs - when aircraft is on the ground.

VaScalea=1.0 Scaling factor to be applied to raw vertical accelerations for heave calcs - when aircraft is in the air.

TCva=0.1 Time constant for initial low pass (smoothing) filter of vertical acceleration in sec/rad.

VaPw=1.0 Exponential factor to be applied to accel values above 1.0m/s^2 to exaggerate response.

VaSat=10.0 Cap level for acceleration magnitude that will be processed for cue in m/s^2.

TCvp=5.0 Time constant for high pass filter to washout heave cue in sec/rad.

Turb_Scalea=0.0 Scaling factor to be applied to recorded light-turbulence heave accel in air.

TCvf=0.1 Time constant for final low pass (smoothing) filter of heave cue in sec/rad.

VAMax=10.0 +/- Heave demand that will give full scale heave of rig (in accel units - m/s^2) set this to the same value as VaSat.

VALim1=10 For Rig_Type=0 Lower bound of heave movement range within the 1-255 scale, for Rig_Type=1 the %tage of stroke length of the start/hold position.

VALim2=000 For Rig_Type=0 Upper bound of heave movement range within the 1-255 scale, for Rig_Type=1 this MUST be left at 000.

[NOTE when Rig_Type=0 setting VALim1 and VALim2 to the same value is a special case for 2 DOF independent actuator platforms. This special case setting mixes some of the otherwise unused heave cue into the pitch and roll axes to allow some heave effects such as touch-down bumps to be felt in a 2 DOF platform with no heave axis. The value of VALim1 sets the percentage of the heave cue which will be add to the pitch and roll axes, so should be in the range 0-100.

Heave_Rev=0 Reverse output sense, =0 No, =1 Yes.

RUNWAY HEAVE EFFECTS SETTINGS

The runway heave motion is generated from two superimposed sine waves. The combination of slow and fast sine waves can be configured using these parameters. The overall effect is scaled using the Turb_Scaleg parameter in the Heave settings section. The notional unit of the wave amplitude is m/s^2 and the resulting value is added to the actual heave acceleration which is used for the heave cue.

RW_Amp_3=0.0 Slow acceleration sine wave amplitude at takeoff speed m/s^2.

RW_CPS_3=0.75 Slow sine wave frequency at takeoff speed - in cycles per second (Hz).

RW_Amp_1=1.0 Fast acceleration sine wave max amplitude m/s^2, set a very small value to effectively disable if platform does not have good high freq response.

RW_Dia=0.5 Wheel Diameter for Fast Wave Frequency - m, set at unrealistically large dia to simulate centerline bumps.

RW_Tos=100.0 Reference take-off speed for calcs - knots.

HOT KEY/BUTTON SETTINGS

Key_Kill=Esc     Kill, Prefix, Drive and Hold hot keys. The drive and hold hot keys require the "Prefix" key to be held down
Key_Prefix=\   at the same time to operate
Key_Drive=d
Key_Hold=h

Joy_But=1    Joystick number for driver remote control buttons, =0 to disable, otherwise set to joystick number on system

But_Kill=2      Kill, Drive and Hold joystick buttons, set any =0 to disable it (these are active only if Joy_But is non-zero)
But_Drive=11
