Movement limits
|
The Min/Max Pan/Tilt angle parameters represents the angles that the protocol min/max values corresponds to.
The mechanical limits are used to limit the movement withing the min/max angles. This is useful if there is some form of obstacle within the cameras movement range. Setting these limits will stop the camera from moving beyond them, this is true for both absolute and relative movements aswell as continuous ones.
The limits are enforced within the camera hardware by updating the software pan/tilt limits.

Absolute movements
|
|
Focus/Zoom is sent for all absolute movements, if the attached camera doens't support either Zoom or Focus the Lens drive has to be inhibited according to the instructions under "Lens Configuration" in the manual. Otherwise the unit will not correctly detect when it has reached the requested positons.

| NumberOfPresets |
The number of device presets positions available in the device. A unit might not be able to handle all 255 presets due to lack off memory, but it will always support atleast 16 |

| MinPanAngle |
The minumum pan angle times 10. This represents how far to the left the device can go. |
-1800 - 1800 |
| MaxPanAngle |
The maximum pan angle times 10. This represents how far to the right the device can go. |
-1800 - 1800 |
| MinTiltAngle |
The minumum tilt angle times 10. This represents how far down the device can go. |
-1800 - 1800 |
| MaxTiltAngle |
The maximum tilt angle times 10. This represents how far up the device can go. |
-1800 - 1800 |

| Field angle compensation |
Calibration constant for click-in-picture (center) movements when using lenses with non linerar zoom scale. Higher values give smaller pan/tilt movements. First calibrate the "Min field angle" and the "Max field angle" limits(see above) and then zoom in half way (optical, i.e. "zoom=5000"). Calibrate by confirming that clicking on an object brings the object to the center of the image. |

The optical data limits are used to tune image centering:
- Zoom out completely and adjust Max Field Angle until the spot you click becomes centered accurately.
- Zoom in completely and repeat for Min Field Angle.
