•OUTPUT
Outputs are either LTP, HTP or PERM. A channel can only output one level at any one time. If it receives
more than one output command, which one should it choose to obey? LTP, HTP and PERM lays down
the rules for this situation, following conventions established for various types of device.
LTP channels respond to the latest command received. Most intelligent light channels are customarily set
to LTP, allowing, for example, overlayed color/gobo information, hence
last takes precedence, or LTP.
HTP channels respond to the highest level instruction received. Such a setting is appropriate for intelli-
gent fixture dimmer channels as mentioned above and also for dimming power packs. If two scenes are
output to the same channels, it will be the highest level signal in each channel that will be obeyed.
PERM channels remain on, even when a general blackout is in force. This is to cater for those lamp
types which need to cool when switched off before they can be switched on again. The PERM output is
also suitable for color changer lamps, while the changing mechanism would be set to LTP.
