3.10 Strobe Control Output Signals
A102f cameras include a feature designed to help you control strobe lighting. The feature allows a
user to enable and parameterize up to four strobe control output signals. The signals are
designated as Strobe_0, Strobe_1, Strobe_2, and Strobe_3.
Enabling the Strobe Control Feature
The Strobe Signal Function control registers (see page 4-15) are used to enable and parameterize
the strobe output signals. To enable and parameterize the strobe_0 signal:
• Set the On_Off field of the Strobe_0_Cnt register to 1 to enable the strobe_0 signal.
• Set the Signal_Polarity field to 0 for a low active signal or 1 for a high active signal as
desired.
• Set the Delay_Value field. The setting in this field will determine the time between the start of
image exposure and when the strobe signal changes state as shown in Figure 3-14.
The delay can be set to a value between 0 and 4095. The units for the delay are 1/1024 ms.
For example, if the delay was set to 100, the delay time would be 100/1024 ms (or
approximately 97.7 µs).
• Set the Duration_Value field. The setting in this field will determine the duration of the strobe
signal as shown in Figure 3-14.
The duration can be set to a value between 0 and 4095. The units for the duration are 1/1024
ms.
Figure 3-14: Strobe Signal
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. See Section 5.7.11 for information on assigning output signals to physical output
ports.
The Strobe_1_Cnt register is used to enable and parameterize the Strobe_1 output signal. The
register is used in similar fashion as described for Strobe_0. Once the Strobe_1 output signal has
been enabled and parameterized, it must be assigned to a physical output port on the camera.
The Strobe_1 signal can only be assigned to physical output port 1.
The Strobe_2 and Strobe_3 output signals are also enabled, parameterized, and assigned to a
physical output port in similar fashion to Strobe_0.
