Release 2.02
=============

2.02:1 Added calibration parameters for the tilt movement.
       Different Cohu models may have different tilt offsets and
       different number of tilt steps per degree.

2.02:2 Added calibration parameter ("Field Angle Compensation") for
       the zoom function (for calibration of different lenses).


Known problems and limitations in version 2.02
==============================================

Note! Some limitations are also model dependent and can behave
      different on different Cohu models!

2.02:3 To use this version of the driver, firmware 4.30 or higher
       is required.

2.02:4 Tilt movement limits are sometimes exceeded during continuous
       movement when set close to the mechanical limits.

2.02:5 A camera address must already be assigned to a Cohu PTZ device
       before using it with this driver (the Cohu PTZ device have no
       DIP-switches for assigning camera addresses).

2.02:6 A zoom move will set autofocus=on. After a zoom move, a short
       delay is required before a manual focus move is possible.

2.02:7 When saving a preset in the Cohu PTZ unit ("device presets"),
       the digital zoom position is not saved (e.g. "device presets"
       are only saved in optical zoom area).

2.02:8 When saving a preset position, only pan, tilt and zoom positions
       are saved in the preset.
