3.10 Strobe Control Output Signals
A620f 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 control registers (see pages 4-38 and 4-39) are used to enable and
parameterize the strobe output signals. To enable and parameterize the Strobe 0 signal:
• Set the value in the On/Off field of the Strobe 0 Control register to 1.
• Set the value in 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 3-11.
The delay can be set to a value between 0 (0x000) and 4095 (0xFFF). The units for the delay
are 1/1024 ms. For example, if the delay was set to 100 (0x064), 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 3-11.
The duration can be set to a value between 0 (0x000) and 4095 (0xFFF). The units for the
duration are 1/1024 ms.
Figure 3-11: 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 6.7.10 for information on assigning output signals to physical output ports.
The Strobe 1 Control 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.
