STROBES
The camera can provide up to two strobe pulses for synchronization with an external
light source, additional cameras or other peripheral devices. The user can set each
strobes pulse duration and the delay with respect to the start of the exposure period
or the start of the readout period. The maximum pulse duration and the maximum
delay can be set up to 1 second with 1.0us precision. The strobe pulse can be
assigned to either external output. Figure 18 shows two strobe signals positioned
with respect to the start of exposure. See Section 2.14 I/O Control.
