9.5 WIPE GENERATOR COMMANDS
If any of the selected effects is not available with the current pattern, no action is
taken. For instance, the selection ”vertical wipe multiplication” or ”rotation” for pat-
tern number 1 is just ignored.
9.5.1 WIPE PATTERN SELECT COMMAND (C8)
The specified wipe pattern number is to be selected. There is no translation of wipe
pattern numbers, so that the wipe pattern number of the Diamond digital has to be
specified.
The wipe pattern numbers are available on lists.
9.5.2 WIPE MODULATION COMMAND (B5)
Only the lowest two bits of the mode byte are evaluated as follows:
Low Bits Effect
00
01
10
11
modulation off
modulation on, modulation locked
modulation on, but not locked
no effect on Diamond digital
9.5.3 WIPE MULTIPLICATION COMMAND (B6)
The highest four bits of the mode byte select the horizontal multiplication factor, the
lowest four bits the vertical multiplication. The values are interpreted as binary
numbers. All values from 0 to 15 are valid. (0 is treated as 1.)
9.5.4 WIPE ROTATION COMMAND (B7)
Only the lowest two bits of the mode byte are evaluated as follows:
Low Bits Effect
00
01
10
11
wipe rotation off
rotation on, rotation mode angle
rotation on, rotation mode coupled
rotation on, rotation mode speed
9.5.5 TRANSITION MODE COMMAND (CA)
Turns the NEXT TRANSITION on or off. The Diamond digital has no next transition
key for PP/DSK so with EX=0 this command will not have much of an effect.
Only bits 0, 1 and 2 are relevant for the selection:
Bit 0 for next transition key 2
Bit 1 for next transition key 1,
Bit 2 for next transition background.
