Ctrl Command select_cor_table
Function assigns the previously loaded correction tables #1 and #2 to the scan head control ports
Parameters
head_a
= 0: turns off the signals for scan head A (primary scan head connector)
= 1: assigns correction table #1 to scan head A
= 2: assigns correction table #2 to scan head A
head_b
= 0: turns off the signals for scan head B (secondary scan head connector)
= 1: assigns correction table #1 to scan head B
= 2: assigns correction table #2 to scan head B
Integration Pascal:
procedure select_cor_table(head_a, head_b: word);
C:
void select_cor_table(unsigned short head_a, unsigned short head_b);
Basic:
sub select_cor_table(ByVal head_a%, ByVal head_b%)
Comments • In a double scan head system, table #1 will be used for scan head A,
and table #2 will be used for scan head B:
select_cor_table(1,2)
.
• However, each of the two correction tables can be assigned to any of the two scan head
control ports. This allows, for example, to switch rapidly between two correction files
for one scan head, e.g. one for a pointer laser and one for the main laser with a different
wavelength. (Use
select_cor_table(1,0)
and
select_cor_table(2,0)
to switch from
one file to the other.)
• The default setting is
(1,0)
, i.e. correction table #1 will be used for scan head A,
whereas the output signals for scan head B are turned off.
Also see chapter 5.3 "Using Two Different Correction Files", page 42.
• The RTC
®
3 3D version can store only one correction file.

Ctrl Command select_list
Function selects which list will be executed upon receipt of an external start signal
Parameter
list
= 0: selects list 1
= 1: selects list 2
Integration Pascal:
procedure select_list(list: word);
C:
void select_list(unsigned short list);
Basic:
sub select_list(ByVal list%)
Comments • By default, list 1 is selected.
• A list can only be started via an external start signal if the list is closed and if no list is
executing at the moment.
