Outputs
Output features are configured by software. Any signal can be placed on any out-
put. The main features of output signals are described below:

description.
Signal Description
IntEna (Integration Enable)
signal
This signal displays the time in which exposure was made. By using a reg-
ister this output can be delayed by up to 1.05 seconds.
Fval (Frame valid) signal This feature signals readout from the sensor. This signal follows IntEna.
Busy signal This signal appears when:
the exposure is being made or
• the sensor is being read out or
• data transmission is active.
The camera is busy.
PulseWidthMod signal
(pulse-width modulation)
Each output has pulse-width modulation (PWM) capabilities, which can be
used for motorized speed control or autofocus control. See Pulse-width
modulation on page 73.
WaitingForTrigger signal This signal is available and useful for the outputs in Trigger Edge Mode.
(In level mode it is available but useless, because exposure time is
unknown. (Signal always =0))
In edge mode it is useful to know if the camera can accept a new trigger
(without overtriggering).
See table 31 and figure 32.
