Ctrl Command set_offset
Function defines an offset in the X and Y directions which will be added to all subsequent vector
outputs.
Parameters
x_offset,
y_offset
offset in bits
Allowed range: [ – 32768 …+32767]
Integration Pascal: procedure set_offset(x_offset, y_offset: smallint);
C: void set_offset(short x_offset, short y_offset);
Basic: sub set_offset(ByVal x_offset%, ByVal y_offset%)
Comments • See chapter 5.1 "Coordinate Transformations", page 40.
References set_matrix, set_offset_list
List Command set_offset_list
Function same as set_offset (see above), but a list command
Integration Pascal:
procedure set_offset_list(x_offset, y_offset: smallint);
C: void set_offset_list(short x_offset, short y_offset);
Basic: sub set_offset_list(ByVal x_offset%, ByVal y_offset%)
Comments • This command allows definition of an offset within a list.
• See chapter 5.1 "Coordinate Transformations", page 40.

Ctrl Command set_piso_control
Function changes the delay which is inserted before the RTC
®
4 reads the Status Signal Word from
the scan head
Parameters L1, L2 lengths of the data cables for scan head A and scan head B in meters
Integration Pascal:
procedure set_piso_control(L1, L2: word);
C: void set_piso_control(unsigned short L1, unsigned short L2);
Basic: sub set_piso_control(ByVal L1%, ByVal L2%)
Comments • This command provides adjustment of the timing of the (bi-directional) communication
between the scan head and the RTC
®
4 to reflect the length of the data cable.
• The command should be used if the data cable is longer than approximately 12 m
(and if the Status Signal from the scan head is to be evaluated).
See also chapter 6.5 "Data Cable", page 55.
• The maximum length for the data cable is 75 m.
