Calibration
The calibration of a Victor SPX is essentially the scale of input signal to output voltage. Different controllers
may have different “max” and “min” signals that may not correspond to the same Victor SPX outputs.
Calibrating the Victor SPX allows it to adjust for these differences so that a “max” signal results in a “max”
output. Calibrating can also correct issues caused by joysticks or gamepads with off-center neutral outputs.
The Victor SPX’s default calibration is compatible with the roboRIO control system.
To Calibrate the Victor SPX:
1)
Press and hold the B/C CAL button until the Status LEDs begin to rapidly blink red & green.
2)
While holding the button, move the joystick (or other input signal) to full forward then to full
reverse. This can be done multiple times. The Victor SPX is looking for max & min PWM values
during this step, so ensure that the joystick reaches its full max and full min.
3)
Release the joystick and allow it to return to neutral. After the joystick is in the neutral position,
release the B/C CAL button.
4)
If the Victor SPX was calibrated properly, the status LEDs will blink green several times.
If the calibration failed, the status LEDs will blink red and the previous calibration will be kept.
Note:
Calibration profiles are saved even if power is removed from the Victor SPX.
To Restore Default Calibration:
1)
Remove power from the Victor SPX
2)
Hold down the B/C CAL button
3)
While holding down the button, restore power to the Victor SPX
4)
Continue holding the button until the status LEDs blink green, then release the button
