Polygon Delay - Scanlab RTC 5 PC Interface Board Installation And Operation Manual

• For RTC5OUT.out version up to 525, zero-length timed
mark or arc commands behave like non-timed mark or
arc commands with a length of zero.
• For RTC5OUT.out versions up to 526, the behavior of
mark or arc commands with a length of zero is
independent of the laser control signals.

Polygon Delay

Between two successive mark or arc commands,
there is no need for a complete stop of the scanners.
Therefore the mark delay between two successive
mark or arc commands is replaced by a polygon delay
