Special Functions - Scanlab RTC 5 PC Interface Board Installation And Operation Manual

Special Functions

• Synchronization of scan system and laser control
– Automatic delay adjustments (see
– Sky Writing (see page
• Pixel output mode (scanning bitmaps, see
page 192)
– Pixel frequencies up to 300 kHz, irrespective of
the 10 µs clock
– 15 ns resolution
– 0–100% laser pulse length
– Pixel-Mode 0 not supported
– Reading of analog voltages is not supported
– Pixel marking on sloped surfaces
• Commands for conditional execution of any list
command (see page 213)
• Possible wobbel motion shapes include not only
circles, but also ellipses, horizontal figure-of-8s,
vertical figure-of-8s, and "freely definable wobbel
shapes". Options for the orientation of the
wobbel shapes are: stationary in space, continu-
ously and automatically adjusted to the current
direction of motion, or any other freely assigned
motion direction. Unlike "classic" wobbel shapes,
"freely definable wobbel shapes" have an option
to vary the laser power (see
• Processing-on-the-fly (see
– two encoder inputs (RS422) with 32-bit counter
for Processing-on-the-fly correction with
encoder signals on 2 axes (see
natively: Processing-on-the-fly correction with
McBSP signals (see page
– 24-bit vector coordinates: objects larger than
the image field are possible (virtual processing
field, see page 120 and
– up to 8 objects within the Processing-on-the-fly
track delay (between trigger and marking posi-
tion, see "External List Start", page
– Accurate "external list start":
If accordingly configured via
set_control_mode, the encoder counter can
be reset via external start signals for synchro-
nizing a Processing-on-the-fly process. The
reset occurs fully simultaneously (without 10 µs
jitter) with the external start signal.
– Compensation of 2D motions (XY table)
• Enhanced signal recording (see
set_trigger4).
