Parameters and commands
The synchronization signal is accessible through pin 6 of the 15-pin D-sub con-
nector. For more information about the synchronization signal, see section
on page 27, and the chapter
Timing of the flash pulses
To ensure high quality image results, the flash pulses should contribute predom-
inantly to the exposure of the images, also the ambient light should be mini-
mized as much as possible.
The first strobe pulse should be placed shortly before the end of internal charge
transfer of the first PIV frame.
The second strobe pulse should be placed after the end of internal charge trans-
fer of the first PIV image.
To minimize the crosstalk between the first and the second image, do not shift
the first strobe pulse position too close to the end of charge transfer. The guard
interval time t
G1
(see
Table 18: PIV mode timing parameters independent from
on page 59) is a recommended minimum. Depending on the
application it may be adjusted individually.
For the same reason, the recommended minimum guard interval time t
G2
(see
Table 18: PIV mode timing parameters independent from other parameters
page 59) for the second strobe pulse should be kept, but depending on the
application it may be adjusted individually.
Synchronization of the flash pulses can be realized e.g. by an external timing
generator that generates a pair of strobe pulses. Alternatively, the synchroniza-
tion can be implemented by using the corresponding output signal of the cam-
era. For information on synchronization output see

Examples
M=5
(0x5 = 0b101), sets the bit field to „- - 0 0 - 1 0 1“.
•
Activates Image on Demand mode (IOD) (weight =
1
)
•
Activates PIV mode (weight =
4
)
•
Sets the Exposure feature mode to Standard. (weight =
0
)
Even though the Exposure feature mode is set to Standard, not to Perma-
nent Exposure mode, the exposure is always active, due to activation of the
PIV mode.
M=7
(0x7 = 0b111), sets the bit field to „- - 0 0 - 1 1 1“.
•
Activates Image on Demand mode (IOD) with exposure timer and frame
duration timer mode (weight =
3
)
•
Activates PIV mode (weight =
4
)
•
Sets the Exposure feature mode to Standard. (weight =
0
)
