3.10 Strobe Control Output Signals
A102
f
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. The Strobe Signal Function control
registers (see page
4-42
) are used to enable and parameterize the strobe output signals.
The text below describes using the Strobe Signal Function registers for Strobe 0 to enable and
parameterize Strobe 0. Strobe 1, Strobe 2 and Strobe 3 are enabled and parameterized in similar
fashion by using the respective registers for each strobe.
Enabling the Strobe 0 Control Feature
To enable 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.
Setting the Delay for Strobe 0
The strobe delay is determined by a combination of two values. The first is the setting in the Delay
Value field of the Strobe 0 Control register (see page
4-22
). The second is the Strobe Delay Time
Base. The Strobe 0 delay will be determined by the product of these two values:
Strobe 0 Delay = (Strobe 0 Delay Value Setting) x (Strobe Delay Time Base)
The strobe delay time base is fixed at 1/1024 ms by default. Strobe 0 delay time is normally
adjusted by changing the setting in the Delay Value field of the Strobe 0 Control register. The delay
value setting can range from 0 to 4095 (0x000 to 0xFFF). So if the setting in the Delay Value field
of the Strobe 0 Control register is set to 100 (0x064), for example, the Strobe 0 delay will be 100/
1024 ms (or approximately 97.7 µs).
The strobe delay will determine the time between the start of image exposure and when the strobe
signal changes state as shown in Figure 3-14.
As mentioned above, the strobe delay time base is normally fixed at 1/1024 ms and the Strobe 0
delay is normally adjusted by changing the delay value setting only. However, if you require a
delay that is longer than what you can achieve by changing the strobe delay value alone, the
strobe delay time base can also be changed. The Strobe Time Base smart feature can be used to
change the strobe delay time base. For more information on changing the strobe delay time base,
see Section
6.7.14
