e) void deselect_cards(void);
- Release all opened device driver handle.
- Before program terminates, it is recommended to call this function.
f) short set_list_size_with(U16 size); // 4000 - 20000
- By default, List1 size = 4000, List2 size = 4000, Q size = 49000
- If you call this function with 20000,
List1 size = 20000, List2 size = 20000, Q size = 17000
g) void get_xy_pos_with(short *xpos, short *ypos, U16 mode);
- mode = 0 ---> commanded position
- mode = 1 ---> offseted position
- mode = 2 ---> calibrated position
- void get_xy_pos(short *xpos, short *ypos); returns offseted position
h) void set_softstart_level_with(U16 index, U16 level, U16 mode);
← void set_softstart_level(U16 index, U16 level);
- mode = 0 ---> 0V - 2.56V level range : 0 – 1023
- mode = 1 ---> 0V - 10.0V level range : 0 – 1023
- mode = 2 ---> 1bit = 1uS level range : 2 – 65535 pulse width
- mode = 3 ---> 1bit = 1/8uS level range : 2 – 65535 pulse width
- mode = 5 ---> 8bit digital out level range : 0 – 255
- If you use function void set_softstart_level(U16 index, U16 level);
0V – 2.56V level range : 0 – 1048
0V – 10.0V level range : 0 – 4095
Pulse Width 1bit = 1uS : 2 – 65535
- analog output 12bit 2ch, analog input 10bit 2ch
i) void load_varpolydelay_with(U16 a1, U16 a2, U16 a3, U16 a4,
U16 a5, U16 a6, double v1, double v2, double v3, double v4,
double v5, double v6);
← short load_varpolydelay(const char* FileName, U16 tableno);
- 0 < a1 < a2 < a3 < a4 < a5 < a6 <= 180
- 0 <= vi (where i = 1 – 6)
- Do not use function void load_varpolydelay();
j) void spot_time_with(U16 time_factor);
- Before using function void spot_abs_with(); which is used for BMP,
set multiplying factor of Laser on time.
- Total Laser on time = time_factor * on_time (See below)
k) U32 read_enc_cx(void); U32 read_enc_cy(void);
- During simulate_encoder(); this function returns the simulated value.
l) Caution
- short load_correction_file(const char* FileName, short cor_table,
double kx, double ky, double phi, double x_off, double y_off);
• cor_table = 1 ---> fixed to master head
• cor_table = 2 ---> fixed to slave head
• kx = ky = 1.0 / phi = x_off = y_off = 0.0
- void select_cor_table(U16 head_a, U16 head_b);
• Do not use this function because it is meaningless.
- void set_softstart_mode(U16 mode, U16 num, U16 restartdelay);
• mode = 1/11, 2/12, 3/13 and 5/15
• mode = 5/15 is for 8bit digital output
(2) List commands (added function)
a) void spot_abs_with(short xp, short yp, U16 on_time, U16 jumpstep,
U16 jumpdelay);
- When long jump, call this function with jumpstep = jumpdelay = 0.
- From version8, on_time means 1/8us
b) void mark_end(void);
- After all marking, if you do not call jump_abs(); it is recommended
to call this function to make sure laser off.
c) void stop_timer(void); void start_timer(void);

2.4 Field correction Algorithm
The CC9054 PCI Interface Board provides a correction algorithm to
compensate for the field distortion. The algorithm is based on a
calibration data table.
An orthogonal grid of 65X65 points is superimposed on the ideal square
image field. The adjusted X and Y coordinates for the correct output of
these grid points are stored in a calibration data table.
To move the focus to any point within the image field, the CC9054
calculates the correct coordinates by interpolating from the grid points in
the calibration table. The result is transmitted to the scan head. The
correction algorithm is executed for every single micro vectoring. |

3.1 Digital Output/Input Port
A buffered 16-bit digital input/output port(TTL level) is available via
JP1/JP3 connector. This port is intended for lasers with power on/off
control. However, it can be used for any other purpose as well, e.g. for
controlling a handler.
3.2 Connectors
(1) Scan Head Connector (XY2-100 type)
The 44-pin D-SUB connector
for the scan head is compatible
with most scan heads which use
the XY2-100 standard.
The MZ channel is optionally
provided for controlling a third
axis in a 3-axis system.

above. The 25-pin D-SUB connector that is connected to JP1 with flat
cable may be installed in PC slots.
