PTZF Swap
The PTZF SWAP facility is an engineering function to reverse the polarities of
the Pan, Tilt, Zoom and Focus drives. When a receiver is initially installed the
direction of PTZF functions should be checked and reconfigured where
necessary.
Feedback Pots
The receiver tests head potentiometers to determine drive feedback and
direction. This also determines whether the head is capable of presets. During
this operation each function (Pan, Tilt, Zoom, Focus) will be exercised by the
receiver as a integrity test. Any faults will be displayed on-screen.
Endstops
These can be set for Pan, Tilt, Zoom and Focus. Alternatively, they can be
switched off.
Speed Table
Eight head speeds can be programmed corresponding to the eight grades of
sensitivity on the right hand joystick. Using this table, it is possible to set up a
Joystick speed curve. An example is shown below.
Error Table
Eight error values can be
programmed corresponding to
the eight speed values set in the
Speed Table. Using this table, it is possible to control the rate that the head
decelerates towards a preset. The value programmed correlates to a distance
away from a target with a head speed. Two example tables are given below.
