To save all current pixel coefficients to EEROM, use the command
write_pixel_coeffs
.
To restore the last saved user settings and the FPN and PRNU coefficients, use the
command
restore_user_settings
.
C5 Setting Direction
The camera's readout direction can be set to forward, reverse, or external input (forward).
To set the direction internal forward, use the command
set_ccd_direction 0
.
To set the direction internal reverse, use the command
set_ccd_direction 1
.
To set the direction external forward/reverse, use the command
set_ccd_direction
2 ;
high is forward, low is reverse, and the default direction is forward.
This command also updates all parameters that are forward/reverse dependent.
C6 Setting Line Rate (EXSYNC)
The camera’s line rate (synchronization) is generated internally or input from a frame
grabber/host system. The source is selected using the
set_sync_mode mode
command through the serial port.
To set line rate internally, use the command
set_sync_mode 0
.
To set line rate externally, use the command
set_syn_mode 1
.
When using internally generated sync, the frequency can be programmed using the
command
set_sync_frequency frequency
, where
frequency
is a number in Hz
between 3500 and the specified maximum line rate. Use the command
set_sync_counter value
, to set the line rate from 3500Hz to the camera's
maximum line rate by applying a counter value. Counter values are from 0 to 65535. Line
rate can be calculated as follows:
Line rate = 1/(minimum line time + counter value * 50ns), where minimum line time is =
1/maximum line rate at applied EXRCLK.
Minimum Line
Times 40MHz 20MHz 10MHz
512 15.575µs 28.8µs 57.5µs
1024 29.725µs 55.1µs 110.1µs
2048 57.275µs 110.2µs 220.0µs
For external sync, the control signal EXSYNC determines line rate. The internal
commands
set_sync_frequency
and
set_sync_counter
are disabled when
EXSYNC has been selected.
When setting the camera to external sync, EXSYNC must be supplied.
