'FRAME BY FRAME' MODE
In all operating Modes (0-7), the PlusCard can be set to only display full
frames of colours, stepping from colour to colour when the control
input crosses standard threshold levels. This is called Frame-by-Frame
mode and is controlled from the 'Frame' control on the rear of the
PlusCard. The different profiles for an 11 colour scroll are shown
below. The scrolling speed between full colours is set by the relevant
mode selected: in modes 0 to 5, the gel moves at the preset speeds;
for modes 6 and 7 the inter frame gel speed is controlled by a DMX
address.
Selecting Frame-by-Frame Mode
The 16 position 'Frame' select switch is labelled 0-9 and A-F where
A=10, B=11 etc. Where proportional position control is required,
select the switch to position 0 (Frame by Frame off). For Frame-by-
Frame operation, select the number of frames after frame 0.
For example:
2 Colours
Frame=1
5 Colours
Frame=4
16 Colours
Frame=F
The Frame-by-Frame software has been designed to include
hysteresis and 'dead bands' between colours (typically 4%). This
avoids any unwanted repeated changes due to noisy analog signals.
