Setting the Duration for Strobe 0
The strobe duration is determined by a combination of two values. The first is the setting in the
Duration Value field of the Strobe 0 Control register (see page
4-22
). The second is the Strobe
Duration Time Base. Strobe 0 duration will be determined by the product of these two values:
Strobe 0 Duration = (Strobe 0 Duration Value Setting) x (Strobe Duration Time Base)
The strobe duration time base is fixed at 1/1024 ms by default. Strobe 0 duration is normally
adjusted by changing the setting in the Duration Value field of the Strobe 0 Control register. The
duration value setting can range from 0 to 4095 (0x000 to 0xFFF). So if the setting in the Duration
Value field of the Strobe 0 Control register is set to 250 (0x0FA), for example, the Strobe 0 duration
will be 250/1024 ms (or approximately 244.1 µs).
The strobe duration will determine the duration of the strobe signal as shown in Figure
3-14
.
As mentioned above, the strobe duration time base is normally fixed at 1/1024 ms and the Strobe
0 duration is normally adjusted by changing the duration value setting only. However, if you require
a duration that is longer than what you can achieve by changing the strobe duration value alone,
the strobe duration time base can also be changed. The Strobe Time Base smart feature can be
used to change the strobe duration time base. For more information on changing the strobe delay
time base, see Section
6.7.14
.
Assigning the Strobe 0 Signal to a Port
Once the Strobe 0 output signal has been enabled and parameterized,
it must be assigned to a
physical output port on the camera
. The Strobe 0 signal can only be assigned to physical output
port 0. Strobe output signals are assigned to physical ports by using the Output Port Configuration
smart feature. See Section
6.7.11
for information on assigning strobe output signals to physical
output ports.
If you enable the Strobe 1, Strobe 2 and Strobe 3 output signals, you must also use the Output
Port Configuration smart feature to assign these signals to physical output ports on the camera.
The Strobe 1 signal can only be assigned to physical output port 1. The Strobe 2 signal can only
be assigned to physical output port 2. The Strobe 3 signal can only be assigned to physical output
port 3.

If you start an image exposure and the strobe signal for the previously captured image
is still running, the running strobe signal ends immediately and the next delay and du-
ration begin.
The Strobe Control Output Signal registers are defined in version 1.31 of the IIDC
specification.
Because the strobe control output signal feature is so new, the Basler BCAM 1394
Driver does not yet include a method call to access this feature. As a work-around, you
can use the techniques described in the tutorial for the Basler Smart Features Frame-
work Software to directly read from or write to the strobe control output signal registers.
