Control
DFW-SX910/X710
PAINT Control
Issue the following commands using BlockWrite or
QuadletWrite.
F0F30000h
<= 08004600h
F0F30004h
<= 0002FFFFh
F0F30008h
<= UUUUVVVVh
Specify UUUU and VVVV within the range from –4
to +4 using 16-bit signed integers.
The values which you set will be preserved even if the
power to the camera is turned off. To restore the initial
value, set UUUU and VVVV to 0.
Memory Shot Control
The following instructions are provided to allow you
to operate the camera in the external synchronization
mode.
1
Stop the video transmission.
2
Set camera features, such as video mode, frame
rate, etc.
If you change the image size to a smaller one, a
higher frame rate will be available.
3
Issue the following commands using BlockWrite or
QuadletWrite.
F0F30000h
<= 08004600h
F0F30004h
<= 0010FFFFh
F0F30008h
<= 80000000h
Then, the Memory Shot feature is activated.
4
Set the external trigger feature to ON.
F0F00830h
<= 82000000h
5
Issue the start capturing command.
F0F40000h
<= 0100nnnnh
nnnn indicates the number of frames to be
captured. When the specified number of frames is
captured or the memory fills up with data, the
capture mode will be released. To find the number
of the frames captured, read out F0F40000h. The
end flag shows that the capture mode has been
released.
0101000Ah
When the mode is released after 10 frames are
captured, bit 16 indicates an end flag.
6
Set the external trigger feature to OFF.
F0F00830h
<= 80000000h
7
Issue the video start command.
The camera outputs the frames in the memory area
and then enters the “idling” state. The frames are
output sequentially in the captured order. You
cannot specify a frame to be output on a random
basis.
8
If output ends, issue the video stop command.
This step cannot be skipped.
One procedure is completed. You can perform the
operation from step
4
over again.
To exit from the Memory Shot mode and
return to the normal mode
Issue the following commands using BlockWrite or
QuadletWrite.
F0F30000h
<= 08004600h
F0F30004h
<= 0010FFFFh
F0F30008h
<= 00000000h
If you perform the procedure with a camera of
which the external Trigger Mode is set to OFF
Capturing starts at the moment you issue the command
in step
5
.
User Memory Control
Issue the following commands using BlockWrite or
QuadletWrite.
F0F30000h
<= 08004600h
F0F30004h
<= 0011FFFFh
F0F30008h
<= 80000000h
The user memory area is opened. User Memory is
mapped to F0F50000h-F0F500FFh.
QuadletRead/Write and BlockRead/Write are
available.
If you issue the following commands using
BlockWrite or QuadletWrite, the user memory area is
locked and will be inaccessible.
F0F30000h
<= 08004600h
F0F30004h
<= 0011FFFFh
F0F30008h
<= 00000000h
Notes on ACR access
The Access Control Register is managed by the time-
out control. A series of commands must be completed
within a time-out duration. The time-out duration is
specified using the ACR access commands.
F0F30000h <= 08004600h
Access control key (32-bit)
F0F30004h <= 0011FFFFh
Access control key (16-bit) +
‘F’ + time-out (12-bit)
F0F30008h <= 80000000h
Control commands
Time-out duration is specified using 12-bit values, and
the unit is 1 ms. FFF indicates 4095 ms.
