• The
init_rtc5_dll
command is also available without explicit access rights to any partic-
ular RTC
®
5 board.
•
init_rtc5_dll
is not available as a multi-board command.
• After initialization of the DLL with
init_rtc5_dll
, you can additionally select between
two DLL operational modes (see
and
®
5 mode.
• The
init_rtc5_dll
command does not cause a reset of the RTC
®
5 board. Board resets
can only be initiated via the command

Normal
List Command
jump_abs
Function
moves the output point (of the laser focus) along a 2D vector at jump speed from the
current position to the specified position (absolute coordinate values) within a two-
dimensional image field.
Call
jump_abs( X, Y )
Parameters
X, Y
absolute coordinates of the jump vector end point in
bits
as signed 32-bit
values; allowed range: [–8388608 … 8388607] (out-of-range values will be
edge-clipped). The complete value range [–8388608 … 8388607] is only
usable as a virtual image field e.g. for (enabled) Processing-on-the-fly
applications. The current coordinates will be clipped to [–524288 … 524287]
(real image field size) during runtime directly prior to use of the correction
table.
Comments
• If the jump speed has not been previously explicitly set via
, then the jump will be executed at a predefined jump speed of
10000
bits per ms
.
• The “laser active” laser control signals are off during the jump (if necessary, they will be
switched off before the jump).
• After a jump command, a (variable) jump delay is inserted. Exception: a zero-length
jump vector’s subsequent (variable) jump delay will not be executed. However, the
command itself still requires a 10
µ
s clock cycle for execution.
• During the conversion of specified coordinate values into scan system output values,
any previously defined coordinate transformations, assigned correction tables etc. are
taken into account after successful microvectorization (see
). As of version
DLL 520, OUT 519, coordinate transformation settings that were only collected until
then will possibly take effect via
jump_abs
,
at_once
= 2).

RTC

5 unchanged functionality (except for the extended range of values).
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified coordinate values by 16
(the permissible range of values is correspondingly reduced).
Version info
Last change with version DLL 520, OUT 519: behavior for coordinate transformations with
at_once
= 2 (see
)
